HYBRID STEEL FRAME + TIMBER TRUSS SOLUTION LEVERAGES LIGHTWEIGHT STEEL

LIGHT GAUGE STEEL WALL FRAME AND ROOF TRUSS TECHNOLOGY SPECIALIST SCOTTSDALE CONSTRUCTION HAS RELEASED AN INNOVATIVE ALTERNATIVE TO TRADITIONAL TIMBER FRAMES FOR HOUSES AND LIGHTWEIGHT STRUCTURES.

ScotFrame enables the use of steel wall frames in combination with timber trusses, confirmed Scottsdale Director – Global Sales, Gordon Simpson, adding the company was targeting builders and timber frame plants with the solution.

“There are many good reasons to choose ScotFrame. Globally there’s a shortage of wood and many companies can’t secure timber supply; steel is a very viable alternative for the 21st century. And it offers unique advantages, among them speed of construction and trueness in terms of the straightness of walls and angles. It’s also about 30 per cent lighter than timber, a palpable advantage in terms of safe and easy on site construction.”

ScotFrame steel walls are anchored using concrete screws and bolts. A screw or nail connection can then be used on a timber ribbon plate to the ScotFrame steel wall top plate. Standard connections are used for the timber trusses, enabling simple assembly for carpenters and on-site contractors, without the need for specialist installers. Meanwhile the use of wood trusses allows for future complex renovations. ScotFrame steel walls are also designed for simple manufacture, from rolling the profiles to assembling the framing.

Simpson confirmed that the company was offering the steel frame solution at a cost well below comparable solutions for traditional builders.

Benefits to manufacturers and fabricators include design and engineering software that is simple to learn, with skills being directly transferable for existing detailers; good margins in manufacturing steel frames; less waste and no sorting required – all items are automatically measured pre punched and cut by the rollformer; less space required for fabrication and storage of raw steel coils; no jigs or tables needed for assembly; light weight for assembly and handling in factory; Simple and quick fabrication technique, without the need to turn the frames over.

Onsite benefits to contractors include easier and lighter to erect wall frames; standard 28mm service holes punched in frames for electrical wires and water pipes; precise straight and true wall frames every time; reduced number of straps and brackets required; simple to fix down framing to foundations; no need for craning wall framing to second level on-site – lightweight frames are much easier to handle. ■
