Supply of non - colour coated galvalume hirib profile sheet of nominal 1015-1020 mm effective cover width and 28-30
mm deep ribs with subtle square fluting in the five pan at nominal 202-205 mm centre-to-centre. The end rib shall be
designed for anti-capillary action, to avoid any seepage of water through the lateral overlap. The feed material is
manufactured out of nominal 0.45 mm Base Metal Thickness (BMT) or 0.5mm TCT, Hi-strength steel with minimum 550
MPa yield strength, metallic hot dip coated with Aluminium-Zinc alloy (55% Aluminium, 45% Zinc) as per AS 1397 —
Zincalume AZ150 (Min. 150 gmssq.mt total on both sides). The steel manufacturer's test certificate for the chemical
and mechanical properties of steel must be submitted for approval by the engineer-in-charge.
