WHAT IS COLD-FORMED STEEL (CFS)?
- Cold-formed members;
- Hot-rolled members;
In Canada, the standard for design of cold-formed steel members are defined in the CSA S136-16, North American specification for the design of cold-formed steel structural members.
WHERE IS CFS USED?
- Steel Building Systems
- Steel Studs & Joists
- Steel Siding & Cladding
- Roof Deck & Composite Floor Deck
- Steel Roofing
WHY CHOOSE CFS?
- Significantly lighter building material compared to industry alternatives such as timber, concrete and masonry resulting in reduced construction costs for lateral force resisting systems and foundations.
- Available design guides, software and technical resources.
- Strength-to-weight ratio that is up to seven times greater than that of dimensional lumber.
- Consistent manufactured product with high versatility and innovative capabilities.
- Standard coating from galvanization/galvalume.
- Alternative coatings for severe environmental conditions available.
- Provides protection from corrosion.
- Referenced durability experiments indicate estimated coating lifespan in excess of 100 years.
- Can be constructed in extreme cold weather conditions without the need of heating.
- Highly sustainable material containing an average of 25% recycled content and having a recycling rate of more than 90% at the end of its lifespan.
- Dimensionally stable and can be fabricated to exact specifications to minimize on-site waste.
- ULC rated designs available for various building code requirements.
- Non-combustible members reducing the fuel source compared to wood construction.
- Referenced fire experiments show structural reduction retention factor remains 1.0 for temperatures up to 700*F and stiffness retention factor remains 1.0 up to 200*F
- Factory penalization of mid-rise steel building components (wall and floor panels) can be completed for mass production, prefabricated and assembled in a factory setting and erected on site to reduce the base building construction time.
- For mid-rise construction mobile cranes can be used for erection.
