Standard for Roofing & Siding
The CSSBI 21M Standard for Steel Farm Roofing and Siding is intended to assist, buyers, manufacturers, and installers of sheet steel farm roofing and siding by providing information that can be adopted by reference where desired. The requirements provided include recommended minimum requirements for such factors as grade of steel, thickness, metallic coating designation, loading and deflections, as well as design, fabrication and erection in general.
The CSSBI S8 publication Quality and Performance Specification for Prefinished Sheet Steel Used for Building Products applies to hot dipped metallic coated sheet steel prefinished with colours of proven durability and suitable for exterior exposure as delivered from the coil coater. Specific requirements are included that cover the base steel, metallic coating, paint qualification tests, exterior exposure (weathering), accelerated corrosion tests, and colour match. This specification can be adopted by reference and sets a minimum level of performance for prefinished sheet steel building products.
The Canadian suppliers to our CSSBI manufacturer members have introduced pepainted product lines to deliver improved performance for today and well into the future: Perspectra Series™ and WeatherX™. These systems are the result of an extensive investigation of the most current paint system technologies for sheet steel products. These are cost-effective systems designed to provide outstanding weathering performance and corrosion resistance.
