Summary for aluminium vs galvalume roofing Discussion
Aluminium vs Galvalume roofing is the core question here: Abhishek Barasia asks whether colored aluminium corrugated roofing or colored aluminium-zinc alloy (55%) steel roofing is better for a 1,00,000 sq ft warehouse, and whether aluminium’s higher cost is justified over time. Umesh Dalela answers briefly that pre-coated aluminium sheets are better for a normal warehouse, suggesting aluminium as the preferred option in that context. Dr. Thomas H. Cook adds an important caution from his area: aluminium can be too soft where hail is a concern, implying that local weather and impact resistance should influence the choice. The thread does not settle the issue universally; instead, it points to a tradeoff between aluminium’s advantages and the durability needs of the specific site.
Q. I am constructing a 1,00,000 sgft warehouse and wish to know which roofing material is better
a) Colored Aluminium corrugated roofing
b) Colored Aluminium-Zinc alloy (55%) steel corrugated roofing
Aluminum roofing is supposed to be costlier but are the advantages of aluminum roofing weigh out the costs in the long run?
Thanks

Sir:
In my area aluminum would be too soft due to the hail.
