The Galvalume^® Steel Advantage

Economic Advantages of Galvalume^® Over Galvanized


Total Coated	Area Per Ton		% Area more in Galvalume^® over Galvanised
Sheet Thickness	Galvalume^® Coated	G-90 Galvanized	% Area more in Galvalume^® over Galvanised
mm	Sq.meter	Sq.meter	%
0.3	406	384	6
0.38	320	306	5
0.64	188	183	3
1	116	114	2

Galvalume^® is a Value-for-Money product as there is significantly More Area Per Ton of coated steel, especially for lower gauges.

Superior Corrosion Resistance

Galvalume^® provides Galvanic & Barrier Protection as opposed to predominantly galvanic protection by Galvanized steel, thus Galvalume^® lasts 2-4 times longer than equivalent thickness Zinc coating (traditional Galvanized sheet) and outlasts Aluminium Coated Type 1 & 2 products, when exposed to same atmospheric conditions.

Packaging

JSW offers effective packaging as per your requirements and in compliance with international norms. Emphasis is placed to ensure durability, prevention of any damage during transportation and better storage.
