— Engineered for Excellence —
Ranki Engineering (Pvt) Ltd imports premium quality Zinc-Aluminium, both colour coated (pre-painted) and in non-colour in coil form from Korea for value addition, by profiling same into roofing, cladding and related accessories.
Since Aluminium is known to possess excellent anti-corrosive properties, it provides a protective barrier against corrosion under normal weather conditions.
Atmospheric exposure tests have confirmed that the corrosion resistance feature of Zinc-Aluminium alloy coated steel is far superior to an ordinary zinc coating, since the 150 gms/ m² coating (coating mass AZ 150) on an average, lasts up to four times that of galvanized steel which has a coating mass of 270 gms/ m² (Z27) in similar environmental conditions.
Material specifications of ZINC ALUMINIUM alloy coated steel and Pre painted steel
Conformity to International Standards:
ZINC – ALUMINIUM alloy coated steel and Pre painted steel conform to the following International Standard Codes:
AS1397, ASTM B117, ASTM A792
ZINC-ALUMINIUM steel is chosen as the substrate for the Pre-Painted Steel range, used in roofing and wall cladding applications.
Pre-painted steel goes through a four-stage process, ensuring long-lasting performance and weather resistance. The result is a finish that combines the strength of steel, corrosion resistance of Zinc-Aluminium, and an oven-baked surface that resists fading, peeling, chipping, and cracking.
A chemical conversion layer is applied to prepare and protect the steel surface.
An epoxy primer is baked onto the surface to enhance adhesion and corrosion resistance.
A weather-resistant exterior-grade topcoat is applied for a smooth, long-lasting finish.
The coated steel is oven-baked to seal the layers, ensuring superior durability and protection.
