C4S Roof Profile
C4S is a unique product to Coverworld, manufactured from Plastisol coated steel, providing an exact match to the old ‘Trafford Tile’ asbestos profile.
CR38 Roof Profile
CR38 profile can be installed on suitable steel or timber purlins with a minimum pitch of 4°, after deflection. This is the strongest of our trapezoidal profiles which makes it useful for use on roofs with greater purlin centres and can be specified for industrial, commercial projects.
Available in the full range of finishes and colours with a matching wall cladding profile (CW38) option.
Crimp curving option also available, subject to enquiry.
Suitable for use as a single skin sheet or as the outer weather sheet of a built-up insulated twin-skin system.
