28 Gauge Zinc Coated Galvanized Steel Coil

What mean of 28 Gauge Zinc Coated Galvanized Steel Coil?

What is 28 Gauge?

Gauges are used to specify the thickness of the sheet metal. Gauge is neither standard nor metric, and its values are independent of those measurement systems. Generally speaking, for the same material, the higher the number, the thinner the sheet of metal.

The term “28 gauge” refers to the thickness of the steel sheet. In the gauge system, a higher number indicates a thinner sheet. Specifically:

  • 28 Gauge Thickness: Approximately 0.0157 inches or 0.40 millimeters. 

Gauge is different from inches in that there is no conversion formula. Even if the non-ferrous metal plate and steel plate are the same Ga., the thickness is actually different.

Zinc-Coated Galvanized Steel

Galvanized steel is steel that has been coated with a layer of zinc to prevent rust and corrosion. There are two primary methods of galvanizing steel:

  1. Hot-Dip Galvanizing: The steel is dipped in molten zinc, creating a robust and durable coating.
  2. Electro-Galvanizing: A thinner, more uniform zinc layer is applied using an electrical current in a zinc ion solution.

1.Product Introduction

Hot dipped galvanized steel coil are processed by continuous hot-dip galvanizing from cold-rolled steel coilZinc coating on both sides can effectively prevent corrosion and rust, and increase the service life of steel plate.
