At Capital Steel Buildings all our structures are built using extremely strong high tensile steel combined with Portal Frame methodology. Portal Frame means that that the buildings are constructed in bays with the bays being joined together by attaching Purlins  and rails horizontally between the sections. The Purlins are normally of a z-section or top hat section design. Buildings constructed from the cold-formed steel Portal Frame method have many advantages over the more traditional hot rolled steel buildings. With a cold-formed Portal Frame the first advantage is cost. This is due to the fact that cold-formed steel technology utilises significantly less steel than hot rolled steel sections.

Also, with cold-formed steel there is no need for welding as the joints are bracketed and bolted togeter and delievered  direct to site from the factory already marked, cut to length and hole punched. .

There is also no need to paint a cold rolled steel structure as the C-sections and also the  Z - sections are pre-galvanised giving the inside of your Capital Steel Building a clean, almost clinical feel. There is also the distinct advantage of reduced transportation costs due to efficient stacking of the cold-formed steel sections and cladding.

Our structures undergo complete structural analysis and testing in the Dept of Civil Engineering at Strathclyde University, Glasgow under Dr James Lim. These are valued development partners with Capital Steel Ltd.
