Galvanized sheets are an all-rounder solution in construction. From building a shed to a warehouse, from fencing to privacy screens for garages, this material can do it all. However, why is it favoured more over other materials? Factors like tensile strength, zinc coating, chromation and more have contributed to the popularity of GC sheets. Let’s discuss how.
High Tensile Strength
Most materials have a limit to the stress they can withstand while being pulled or stretched. In brittle materials, the tensile strength is close to the point of yield. In more ductile materials, the ultimate tensile strength is higher. Tata Shaktee galvanized sheets have a high tensile strength of 700 MPa, which enables them to withstand extreme conditions like hailstones and other natural forces. It also helps them bear substantial burdens, providing dependable and long-lasting coverage.
Uniform Zinc Coating
When the zinc coating is uniform on a GC sheet, it extends its durability and longevity. Stainless steel sheets are galvanised by immersing them in molten zinc, which covers the surface, producing a uniform coating. This is crucial since the layer of zinc provides anti-corrosive properties. Therefore, if it’s uneven, the non-galvanised parts will corrode faster, reducing the sheet’s lifespan drastically.
Superior Adherence
Superior technology and processes ensure proper surface cleaning before coating. The cleaner the surface of the steel, the better the zinc adhesion will be. If the surface of the steel is unclean, the adherence to the zinc coating is low. This will cause the galvanised surface to peel off, reducing the sheet’s lifespan.
Tata Shaktee GC sheets ensure superior zinc adherence which preserves durability even under challenging conditions.
Perfect Overlapping
Consistent corrugations on a galvanized sheet enable perfect overlapping, which results in improved weather-proofing. Moreover, there is no unnecessary particle and moisture retention between the overlapped joints. Therefore, it prevents corrosion from originating within the overlappings. Uneven corrugations also lead to gaps, resulting in a badly fabricated roof. Perfect overlappings also allow for effortless installation and watertight structures.
Adequate Chromating
When sufficient chromate solution is used at the galvanising stage, it prevents the formation of white rust. As a result, the sheet’s lifespan is enhanced. It also makes the galvanized sheets more capable of resisting harsh weather conditions.
With such impressive factors, it’s no wonder why GC sheets are popular right now! At Tata Shaktee, we combine high tensile strength, uniform zinc coating and more to ensure your roofs last for many years, reducing the need for repair or replacement.
