Many Benefits of Galvalume that most people are unaware off

Galvalume is a tough, durable coating that protects the steel from corroding. Although corrosion resistance is the best benefit that galvalume promises, there are many other benefits Galvalume is known for. Before we dig into it, let’s have a look at what is galvalume and what are its uses.

Galvalume Overview

Galvalume is made by combining aluminium and zinc in the ratio of 55% to 44% and some amount of silicon that ensures durability and even adhesion. It is the aluminium that differentiates galvalume from galvanized steel. Steel coated with galvalume has a similar appearance to galvanized steel but has a smooth appearance made possible by binding all crystals to close together. 

Application of galvalume is via the hot-dip process. It applies to both the sides and offers protection to edges as well. Usage of zinc and aluminium in the coating lends it the property of aluminium to enhance protection capabilities above and beyond zinc. While aluminium offers barrier protection, zinc protects against scratches. Zinc also prolongs the life of steel that lies underneath. 

The Benefits of Galvalume

As mentioned earlier, the primary benefit of galvalume is corrosion resistance. The addition of aluminium enhances the coating’s corrosion resistance. Robust protection is guaranteed if the steel panel is in an area where high humidity predominates such as marine environments. Other benefits of galvalume coatings include:

1. Galvalume coatings do not add to the weight of the steel. Therefore, the metal’s chief strength to weight ratio is kept. Similar to steel, the coating is strong. The coating also doesn’t flake or crack when the sheet is bent and is flexible enough. 

2. Galvalume coated steel also has superior reflectance in sunlight. This reduces heat absorption through roof panels. Re-emissive pigments added to the coatings improve energy efficiency and protection from corrosion. Insulation properties of sheets coated with galvalume leads to saving of costs in both summers and winters. Galvalume is also resistant to high temperatures. 

3. Besides energy efficient, the galvalume solar sheet price in India is also less than stainless steel. It comes with minimal maintenance and repair needs. Galvalume has a service life of 40-60 years. 

4. Galvalume is used in both architectural and structural roofing. Galvalume steel panels can be installed over any surface ranging from asphalt shingles to wood underlayment. 

5. Galvalume enhances the versatility of steel. Galvalume coated steel can be bent, stamped, rolled, and fabricated without losing the protection of the coating. Galvalume also improves the fire resistance capacity of a surface. 

Make sure to select a reputed company such as JSW Steel when hunting for galvalume. JSW is the first licensed galvalume produced and top steel manufacturers in India that uses technology from BIEC International Inc., USA.
