Alstro is one of the leading metal-business and exporter of Galvanised Steel. Galvanised steel is corrosion resistant, eco-friendly, durable, light weight and high in strength. During the process of galvanising, zinc reacts with steel and forms zinc-iron alloy layers. These layers are bonded metallurgically to the base steel, with the relatively pure zinc layer on the outer surface to act as a protective coat. It creates an impervious barrier on the steel, thus preventing it from coming in contact with moisture and preventing corrosion.
Also, galvanizing enables the sheet to achieve excellent adhesion and abrasion resistance. Another shielding mechanism is zinc’s property to galvanically protect steel. When base steel is exposed to cuts, edges or scratches, the zinc coat’s corrosion protects the steel.
Features
