Product Specification

Cladding Standard

The CSSBI 20M Standard for Sheet Steel Cladding for Architectural, Industrial and Commercial Building Applications is intended to assist specifiers, designers, buyers, manufacturers, and erectors of architectural sheet steel roofing by providing information which 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. Currently the CSSBI does not have a standard specifically for the structural standing seam roof panels.

Paint Specification

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 prepainted 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.
