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
mm Sq.metre Sq.metre %
0.3 406 384 6
0.38 320 306 5

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.
