Description

ISO 4998 Hot-dip zinc-coated Galvanised Steel Coil 0.8*1250MM Mini Spangle Chromate Conversion Coating

ISO 4998 is an international standard that specifies the requirements for continuously hot-dip zinc-coated carbon steel sheet of structural quality. It covers the general requirements, dimensions, mechanical properties, and coating requirements for hot-dip zinc-coated carbon steel sheets used in structural applications. The standard provides guidelines for the zinc coating weight, surface finish, and other properties of the zinc-coated steel sheets.

Hot-dip galvanizing is a method of applying a protective zinc coating to carbon steel sheets. The steel sheet is immersed in a bath of molten zinc at high temperatures, typically around 450°C (840°F). The zinc reacts with the steel surface, forming a metallurgical bond and creating a zinc-iron alloy layer.

The zinc coating provides excellent corrosion protection to the underlying carbon steel. It acts as a barrier between the steel and the environment, preventing moisture and corrosive substances from reaching the steel surface. The zinc sacrificially corrodes, protecting the steel even if the coating is scratched or damaged.

The hot-dip process ensures strong adhesion between the zinc coating and the carbon steel sheet. This results in a durable and long-lasting protective layer that can withstand exposure to various weather conditions and corrosive environments.
