Product Description

Good Thermal Resistance Hot Dip Galvanized Steel Coil For Architecture Roofs

01. Anticorrosive:13 years in heavy industrial areas,50 years in the ocean,104 years in the suburbs and 30 years in cities.
02. Cheap:The cost of hot-dip galvanizing is lower than that of other coatings.
03. Reliable:The zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more durable.
04. Strong toughness:The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
05. Comprehensive protection:Every part of the plated piece can be galvanized,and is fully protected even in depressions,sharp corners,and hidden places.
06. Save time and energy:Galvanizing process is faster than other coating methods.

Brief Introduction

Galvanized Steel Coil gets coated in layers of zinc because rust won't attack this protective metal. The most external layer is all zinc, but successive layers are a mixture of zinc and iron, with an interior of pure steel. These multiple layers are responsible for the amazing property of the metal to withstand corrosion-inducing circumstances. Zinc also protects the steel by acting as a "sacrificial layer." If rust does take hold on the surface of Galvanized Steel Coil, the zinc will get corroded first. This allows the zinc that is spread over the breach or scratch to prevent rust from reaching the steel. For countless outdoor, marine, or industrial applications, Galvanized Steel Coil is an essential fabrication component.

The Protection Principle

1. Anodic reaction: Zn-2e=Zn2+

(The alloy coating loses electron, sacrificing itself in dissolution.)

2. Cathodic reaction: Fe2++2e=Fe

(Fe gains electron reaction, being protected)
