Why steel buildings require highly experienced demolition contractors to demolish them



A lot of the Cardiff demolition that goes on every year within the city will involve dismantling and demolishing steel-framed buildings.
These need to be demolished and approached differently than how you would demolish say a building made from brick, stone and masonry.
The reason for this is that often very heavy, sections of steel will be at great height, therefore extra care needs to taken when demolishing these buildings.

The excavator needs to approach the steel building quite close, and we then use something called a metal shear, which cuts through the RSJ beam.


Demolition and factory strip-out

Sometimes, a company will take over a large warehouse, yet the previous tenant might have left vast amounts of steel racking, machinery or internal buildings that are no longer needed.

An excavator often needs to track through the roller shutter doors and then start dismantling the racking and taking all of the waste to be recycled.



Factory strip-out

We, therefore, can completely demolish and flatten the whole metal building, or we could carry out internal demolition work, simply removing plasterboard partitions, that are no longer needed, or perhaps lifting a heavy piece of cast iron machinery onto a lorry, or it may entail demolishing a breezeblock building.

We can do it all, whether the buildings made of metal, stone or brick we can demolish it for you.

Why steel buildings need extra attention when demolishing

However, the steel framework, that is used to construct the building can often be under a lot of tension, and also stress, so this is why you need a highly experienced demolition company to undertake the work.

For example, the demolition excavator often needs to be close to the building, and if the steel beams are not cut the correct way, the shear could slip, and the metal beam could fall potentially hitting the cab of an machine.

This can result in a loss of life, because the metal beams used to construct buildings are so heavy, and it’s not like a few bricks, stone or masonry simply bouncing off the cab of a machine, no a metal beam will simply crush the occupant within the excavator, so this is why extra care is needed when demolishing metal buildings.


Method statements and risk assessments

A highly experienced demolition company, like ours, based in Wales will often need to visit the demolition site, and have a walk-through and around the building. This is of course if it safe to do so.

With some fire-damaged buildings, it might be unsafe for anybody to enter say the factory. Therefore, looking at the building from a distance, a plan of work needs to be considered, then this is when the method statements are drafted.


Method statements and risk assessments

Then, detailed method statements and risk assessments must be created; and these must be written carefully with great thought going into how the steel building will be demolished.


Factory Demolition

There is a need to set out exactly how the factory will be demolished; usually, the safest way is to use a vast, perhaps even a 50-ton-plus excavator fitted with a hydraulic shear, which will cut through the metal quickly.

There are many highly experienced demolition contractors throughout the United Kingdom.

However, there is a reason why South Wales demolition Ltd are asked to demolish so many steel buildings throughout the United Kingdom.
That is simply because we have a highly experienced team of demolition managers who can advise on how the method statements and risk assessments should be written. also, sometimes the company will need to obtain advise from an external health and safety adviser as well.

Because we have demolished so many metal buildings here in Cardiff, ranging from vast and car showrooms, through to fire damaged buildings in the Valleys, which have had equipment left in the building, which is well over 10 tons in weight, often that item can’t be salvaged it, therefore, needs to be lifted by our powerful excavators.

Therefore, we have successfully demolished many steel buildings throughout the United Kingdom, transporting our excavators and a low loader to all corners of Britain to carry out our demolition work.

Our powerful excavators can be fitted to the end with a shear, so that we can cut the steel, and then another digger can lift them and load them either onto a truck or into a waste bin.

The metal is then transported to a recycling yard; often, the steel is exported worldwide.


Steel dismantling and demolition Cardiff

We offer some of the best prices to either partially demolish part of the building or take away the building entirely. We have a range of trucks, excavators, and attachments that can be used to demolish the building.

We have the demolition excavators, the staff, and the attachments to demolish any building safely. So please do call us today.

How do you ensure that the majority of the waste from your demolition contract is recycled?



When you are demolishing a huge building, such as a hospital, there are quite literally tons of waste are created. This could be plastics, rubble perhaps it could even steel. This all needs to be sorted and then recycled. However, with that said, some demolition companies will recycle more waste than others. So, we thought we would write a comprehensive article, explaining exactly how we recycle as much of the waste as we possibly can.


Do you demolish steel buildings in Wales?

We most certainly do, we have invested in large excavators, which are very powerful and allow us to demolish metal buildings.
Are you also able to demolish residential structures as well?

We most certainly can, whether it is a house, perhaps it’s a block of flats, we can safely demolish the whole building in a short period of time.


Can you write the health and safety method statements and risk assessments?

We most certainly can, in-house we can create certain method statements and risk assessments these can be created in a relatively short period of time then they can be submitted to local councils, such as Cardiff County Council for approval.


A large powerful jaw crusher is

A jaw crusher is simply a very powerful machine, dates are powered by a large diesel engine, which moves open and closes a jaw, The excavator is used to drop rubble, such as bricks, stone, and mortar into what is called the hopper.

Out the other end emerges aggregate, known as hard-core, which is widely used as the base for roads, and also to construct the foundations of the building. Therefore around 100% of the bricks and the stomach can be recycled, what’s even better, is this reduces the number of lorries that are needed to transport the stone off the demolition site, so not only are you recycling the product, but you are also reducing the amount of trucks, that are needed to transport the waste to another recycling yard.


Metal recycling

Again around 100%, of the steel that comes out of a demolition site, can often be completely recycled and made into for example new cars. We have huge, very large excavators, which are fitted with specialist demolition machines, these cut through the metal like a hot knife through butter.

Then once the steel has been cut into smaller sections, it’s time to take it away recycling yard, where it can get completely recycled.
We have a range of huge excavators, these demolish many buildings within the city of Cardiff, yet we also frequently travel to the large Bristol as well. We then completely demolish factories, warehouses, and light industrial units.

We also have other demolition equipment such as 360° rotating grounds, which can pick up the steel from the ground, and it carefully into a skip.



When you are demolishing a house, or perhaps a commercial building, a lot of waste comes from the UP the sea windows and doors.
What’s great about the DC windows and doors is that the frames are wanted, as the company often manufactures back into new doors and windows, therefore using our excavators that have a rotating wrap, in a matter of seconds we can pick out those items, and we can place them into a separate skip, so that they can get recycled as well.

How are various building materials recycled on demolition sites?




Each and every year a wide range of different buildings are demolished right across the city of Cardiff. From hospitals, through to just a simple humble garage require demolition, and then all of the waste will need to be recycled.

We demolish everything from Victorian houses through hospitals

Every month, we demolish a wide range of buildings, ranging from Victorian house, but that’s mostly made of brick and stone. On the other end of the spectrum, could be a large concrete-built building that requires what’s called a “hydraulic hammer” to keep striking the concrete until its broken into pieces.



Helping to protect the environment

As more people rightly focus on protecting our amazing and great planet, protecting the environment and the eco-system is of huge importance, so is now a much greater emphasis now more than ever to recycle building materials, such as stone, brick and plastics.

So how are building materials recycled on demolition sites?

The vast majority of the buildings, but that we demolish within the city of Cardiff in South Wales, as well as right throughout the Vale of Glamorgan, will include buildings that have a large amount of stone, brick, plastics rubber within the building, there’s also likely to be a lot of timber as well.



How is timber recycled?

Timber within a building, is often found within the wooden floorboards, within the structural timbers which make up the roof joists, batons and timber beams as well as also within the walls sometimes as well.

Wood is often recycled in a few different ways; we think that the best way is to salvage the timber, that’s so it can be reused. Even if the wood is given away for free, yet goes on to be used within a home for perhaps the next 100 years, well, that’s great way of helping to protect our planet, as less trees will need to be cut down.


Why not purchase timber from a Cardiff reclamation yard?

The timber can then be sold to say a reclamation yard, such as a reclamation yard in Cardiff, where it can go on to be reused, for example the floorboards could perhaps go into another property, and they could be therefore around another hundred years?

The alternative, is to send the timber to a recycling facility, such as a biomass / wood recycling facility whereby it often put through a machine and made into wood chips.

The wood chips can then be made into biomass, which helps to generate electricity.


How is stone and masonry and bricks recycled?

Bricks and also the stone can be 100% recycled, they can be put through something called a “jaw crusher”– this is a brilliant machine, whereby you feed at one end stone and bricks, and out of the other end flow what is called, crushed hard-core.

This can be reused as the base for roads, it can also often be used within the foundations, of new buildings.


What happens to the plastics?

Within a building can be quite a lot of plastics, for example plastics can be within the UPVC windows and doors.

On top of that there could be also plastics which are used in the soffit boards of the house.

What’s great is that UPVC doors and also the windows can be easily recycled, this plastic is often used to make new windows and doors.


Non-ferrous and ferrous metal recycling

Throughout a house there will be quite a lot of ferrous and also nonferrous metals, such as lead, copper and aluminium.

For example, there is often a lot of copper pipework used throughout the house, as well as sometimes copper hot water tanks, to help keep it warm through the homes central heating system.

Then you will also have a lot of ferrous metals, for example you will also have a lot of steel that is sometimes used within the guttering, it might be used also for some RSJ beams as well.


Demolition within Cardiff

We have demolished many properties, such as houses within the city of Cardiff, this could range from say very large 5-bedroom Victorian houses, that made from brick and also stone.

We have also demolished much more modern properties, for example a house that might’ve been built fairly recently within the 1980s, so the house might not that old, yet an architect may advise that it’s best to be demolished, that’s if you want a house to have a totally different internal layouts inside and for the building to be heavily extended.

Sometimes its more cost effective, to demolish and rebuild a new property.

What’s great about picking our company, is that we will aim to recycle as much of the waste as we possibly can, either through using jaw crushers or perhaps simply taking the wood, to timber recycling facility.

We are also one of Cardiff’s most established and also respected demolition and site clearance companies, we have a large range of different excavators, we have a fleet of Hitachi excavators, which are perfectly suited to safely demolishing any type of building within the city.

We can demolish anything, perhaps it’s a large fire damaged warehouse, that is incurred a lot of damage through a large fire which may have partially collapsed the roof?

The heat might have been so intense, during the fire in a warehouse, that it might have actually bent the steels within the building.

Then, we can also demolish residential housing as well, we also offer free and competitive prices throughout the city.

The different types of buildings that we demolish within the Cardiff area


At any one time, there are various buildings being demolished within the city of Cardiff in South Wales. From large steel buildings, such as car show rooms, through to streets of housing that need to be demolished, for better for energy efficient housing to be built in its place. Therefore, demolition contractors Cardiff, are always in strong demand.


Demolition management that has 40+ years’ experience.

When it comes to demolition management, we have managers that could quite literally right the book on how to demolish buildings. Whether it’s a large car show room, buildings made of concrete or brick, our managers will know how to safely demolish the building. Which type of machine should be used.


We specialise in demolishing steel buildings, such as factories and warehouses

Steel buildings need to be demolished in a different way from brick-built structures, such as houses.
The reason for this is, steel buildings are very strong, and the steel needs to be cut, it requires cutting via using propane, oxygen or it can be cut using a shear, which is attached to an excavator.

The shear can then cut the sections of steel, and cut the RSJs into manageable sections of metal, which can be loaded onto lorries, and taken away.

Often large excavators are needed for this type of Cardiff demolition, for example, often 30+ ton machines, which have the power to cut through the steel, often cutting large angle iron, RSJs, and also metal beams in seconds.

This metal can then be taken to a local scrap yard for recycling. We specialise in steel demolition, whether that’s demolishing a warehouse, a factory or a light industrial unit.



We demolish steel buildings, right throughout South Wales.

Internal demolition

Its sometimes the case, that the owner of say a large factory, doesn’t want the whole building demolished, using large high-reach excavators.

Sometimes, instead, the owners may want say an old piece of machinery, metal racking, or let’s say an internal building demolished.
Often this work needs to carried out over a weekend, such as during a bank holiday, so the noise and vibration doesn’t affect the business when it is open, and say manufacturing items.

We have the demolition equipment, the excavators, the staff, to demolish any type of metal building.

We can demolish steel buildings, separating the non-ferrous, and ferrous metals, we can use a range of Hitachi excavators, which can range from 14 ton to over 30 ton.

We travel throughout the United Kingdom, demolishing steel buildings, whether the structure needs to be cut into sections by a burner, that’s a person who uses oxygen and propane to carefully cut the steel into sections, then the sections of steel, can get loaded onto a lorry.

Sometimes the building will need to cut into sections, via use of a metal shear, the excavator can pull down the steal RSJ’s, then using a shear, the metal can be cut into sections, then loaded into recycling bins, where the scrap is taken to a local metal recycling yard, where the non-ferrous, can be sorted from the ferrous metals, and sent for recycling,


Metal recycling here in South Wales.

Our company can therefore demolish steel buildings, we can take tons of metal to a scrap yard, so that all of the metal can get recycled.
The metal then is often made into new cars, washing machines, or even tin cans, for baked beans!

How we safely dismantle and demolish steel buildings



Right across the United Kingdom, a large number of steel framed buildings, will often need to be demolished and dismantled every year by various demolition companies.

This is often because a company or landlord has bought the site, therefore they might need to build a larger factory or warehouse on that same site.

Therefore, the old building, that is the factory might not large enough for the new company that has bought that site.


If you need the following buildings demolished, we can help:

– Steel factories
– Warehouses
– Steel framed buildings


How do you demolish a steel building?

First of all, an asbestos report will be needed.

Therefore, first of all an asbestos company will need to go out and visit the demolition site and to carry out an asbestos survey to sea if there is any asbestos within the building.

Therefore before any demolition work can be carried out, and before any demolition excavators start working, the asbestos will need to be fully removed from the building in its entirety.


Health and safety method statements and risk assessments

The next stage is to create health and safety method statements and risk assessments these will need to be created.

A detailed demolition method statement will need to be created, which gives step-by-step instructions for the site management to follow.

It should detail everything from the excavators that will be used, right through to how the demolition company will prevent noise from disturbing the local residents during the demolition process.


The next stage would then be to consider dust suppression

When you are demolishing any type of building, whether it be a residential house or perhaps a large factory, normally a lot of dust will be created during the demolition process.

When you consider an old factory that needs to be demolished, the steel sheets, or the steel beams, on the steel angle iron will often have a lot of dust, built upon the steel building during years that the building was used to manufacture goods.


How do you manage dust during the demolition process?

If a large excavator was to come along and start to rip off all of those exterior metal sheets, then dust is likely to escape into the air, causing health issues and also a nuisance to the local area, such as the local residents would see a mass of dust blowing over and into their properties.


Dust suppression

Therefore dust suppression equipment will need to be brought into the demolition site, this could be a water cannon, or even a old fire engine can be used, which puts a huge jet of water into the air to help reduce the amount of airborne dust and also pollutants that are caused by the demolition process.


Next, it’s time to bring in the demolition excavators

Depending on the size of the steel building, will dictate what demolition excavators need to be used.

For example, for a single story steel building, sometimes it’s perfectly sufficient to use a 14 ton excavator fitted with a rotor grab fitted to a machine such as a Hitachi excavator.

Then it’s time to start taking down the building, but sometimes a 14-ton machine won’t be enough, sometimes a larger excavator is needed such as a high reach excavator.


What is a high reach excavator?

For those that do not know a “high reach excavator” is, well its simply an excavator that is normally around 70 tons in weight or above, it has a huge arm, rendering it capable of reaching the top of some tower blocks, steel framed buildings, as well as also other types of structures as well such as bridges for example.



Then it’s time for the demolition work to begin, and this normally starts with taking off the steel sheets, which clad the outside of the building.

This is often done through use of a rotor grab, fitted to a Hitachi demolition excavator, which can rotate 360° and grab the steel sheets, and place them in a steel recycling bin.

There is time to start cutting the structural steels, normally a shear is used for this, a sheer will cut the steel angle iron, and snip into bits.

Then it’s time to bring in the shear so that it can start cut the RS J beams and cut these into sections, and either place these on to an 8-wheeler lorry, or a large recycling skip.
