Frame

Steel frame systems provide contractors and their clients with peace of mind that the build can be carried out faster and more accurately than with traditional methods.

The market for steel framing is expanding at a rapid rate and it offers numerous benefits, from high strength and longevity to the versatility and cost-effective nature of the system. But what are steel framing systems and how do they work?

What are steel framing systems used for?

Steel framing systems can be used in numerous ways, from constructing large steel buildings to dry lined walls and industrial buildings. The steel structures create a skeleton frame which comprises vertical columns and horizontal beams which are riveted, bolted or welded together to create a grid. They are typically used in infill situations where they are installed between the primary structure of the building. 

Steel frame systems aren’t just used for high rise buildings like office blocks and skyscrapers but also extensions for a residential property, for a cost-effective way of separating a new space, or for outbuildings such as a barn, garden room or another structure that requires support for the other building materials. It can also be used for commercial buildings like retail settings or leisure centres, schools and educational environments or hotels and hospitality settings. 

It’s a very versatile approach for creating a secure structure that can then be built around, whether that’s cladding exterior walls, adding traditional brickwork or glass panels. It can also be used for creating internal wall partitions as well. 

Benefits of using a steel frame system

There are many benefits for steel frame systems. One of the primary reasons it’s gained popularity since it was first introduced in the 1920s is that it’s incredibly fast to construct. The frame needs to be bolted or welded together but the components are pre-fabricated, so they’re quick to build on-site. Since steel is a durable material, it’s a great material for hardwearing load-bearing framing that is able to withstand a lot of weight.

Steel can also withstand extreme temperatures, from hot summers to freezing winters, without affecting its structural integrity which makes it ideal for this purpose.  A steel frame system won’t crack or warp like wood or concrete, and there won’t be issues with water retention or corrosion. It’s an environmentally friendly material that delivers versatility and adaptability to any project. 

How much does steel framing cost?

The cost of steel framing is higher than a wood frame or traditional metal studs, but it does offer benefits that these materials do not, which may balance the price for some projects.

A 3000mm length of steel frame base track will set you back around £25 compared to just £4.50 for the equivalent metal stud or £4.70 for a wooden stud. However, a steel frame is far stronger and provides a sturdier base for partitions in a building to support the weight from the primary structural frame.

There are several factors which can influence the cost of a steel frame, such as the type of steel you use. Carbon steel, stainless steel or specialist finishes will all impact the final cost considerably, as will the supplier you use. The transportation costs can also affect the price – a one-floor structure that’s being transported to an easy to access site compared to a high rise building that requires framing 20 floors up will naturally cost different amounts. Lastly, if there are special fixings required, such as bracing straps, these will cost extra. 

How to install a steel frame stud wall

Steel frames are great for internal walls. They are built from tracks along the top and bottom, with studs which slide into the tracks to create the wall. The ease of installation and removal makes this a popular method – you can ensure the outer borders fit together perfectly with the walls before you begin drilling. The steel frame itself can be drilled into so you can fit the top and bottom tracks to a variety of materials, from concrete and wood to bricks. 

To insert the stud into a track, you will need to insert it on its side and twist it so it snaps together tightly. Through this you then attack the border studs using screws (pre-drill pilot holes first to make this easier). Screw the tracks and studs together on the top and bottom sides using flat head screws so they can be covered over with the drywall easily. 

When the framing is in place, insert the inner studs in the same way. These studs don’t need to be screwed into place and can be spaced out at consistent gaps in the wall, usually either at 40cm or 60cm. You can then fill the wall with insulation and fit the plasterboard over the top using plasterboard screws into the studs. 

To conclude

Steel frames are popular in various construction projects, particularly for load-bearing walls in large buildings. They can withstand higher weights, are corrosion, water and fire-resistant, and they’re fast to build.
