Hi-Rib Roof and Wall Cladding Systems
Hi-Rib Roofing and Cladding systems are metal sheets with corrugation, corrugation gives high strength to the sheets. Our sheets are light weight which gives 1000 mm wide coverage with 30 mm rib depth at 200-250 mm c/c with two/three stiffener ribs which makes it the strongest profile in its category.
Base Material
There are basically two types of material-Galvalume and Galvanized steel.
Galvalume
Galvalume high tensile cold rolled steel as per AS:1397, -coating class AZ 150 (min 150gsm/m2 zinc aluminium alloy coating mass, total of both sides), 550 MPa/300 MPa yield strength. The alloy coating comprises of 55% aluminium, 43.5% Zinc and 1.5% silicon. Available in bare finish and colour coated finish with sheet thickness between 0.47mm to 0.60mm.
Galvanized Steel
Galvanized cold rolled steel as per IS:277, coating class Z 120 (min 120gsm/m2 zinc coating mass, total of both sides), 240 MPa yield strength. Available in colour coated finish.
(Consult Blua for any non-standard thickness/colour/yield strength will be made available on demand.)Fixing Procedure
The sheets shall be fixed over the purlins/Girts with Zylon coated hex head self drilling fasteners with integrated neoprene/EPDM washers.
Blua Hi-Rib sheet is also available in Crimped Curved Shape. It can be used to give building a unique aesthetic look.
