Cold rolling is the process whereby steel is treated below its recrystallization temperature which is versus to hot rolled steel to produce uniform, flat steel coils. Not only does this compress the thickness of the material, but it also boosts tolerance, improves tensile strength, and smooths surface finishing by hardening the inner strains of the metal. The cold rolling process results in an estimated 20% improvement in overall steel strength, so it's easy to see why cold rolling is coming into higher and higher demand among industry professionals, engineering firms, and product designers.
1. Light in weight : These profile sheets use steel or aluminum as the base material, hence the weight of these profile sheets are light in weight and thus exert minimum pressure on roofs or floors.
2. Heat insulation : These sheets are coated with colors which have better insulation properties.
3. Water resistant : The coating on these sheets is of standard thickness that doesn’t allow water to seep through these.
4. Weatherproof : In extreme weather conditions like windy, rainy weather, these lie sturdy on their position without getting damaged
5. Extreme loading capacity : All the sheets are good in tensile strength that helps to bear heavy loads without getting damaged.
6. Attractive appearance: Available in beautiful colors and designs and thus are very attractive in appearance
7. Green and environmental : Color and other materials used in these sheets are eco-friendly and have not any harmful effects on the environment.
8. Economical : These sheets are very economical and thus can save lots of extra costs like installation costs and maintenance costsAdvantage
