* Line loads as defined in BS 5950 Part 6 Section 2.2. Roof loading should be calculated in accordance with BS 6399 : Part 3 Part 2 for wind loading) CP & P recommend using a line load of 3kN/m and a minimum imposed UDL of 1.5kN/m2. Snow and wind loading may be more severe than this, however.

These load span tables have been calculated in accordance with BS5950 Part 6, and provide safe working loads (factor 1.5). All profiles comply to MCRMA manufacturing tolerances. Information contained within this document is subject to change as Corus is constantly developing it's products.
