Product Description

Product introduction

Hot dip Galvanized steel coils are widely used in the construction industry, as raw Material for the production of corrugated panels, fencing products, drywall panel profiles, ventilation systems etc. Recommended for both outside and inside usage, galvanized steel has a high resistance to corrosion in different environments, due to a protective layer of zinc of 100 – 275 grams per squaremeter.

Galvanised steel is mild steel with a coating of zinc The zinc protects the steel by providing cathodic protection to the exposed steel, so should the surface be damaged the zinc will corrode in preference to the steel Galvanised steel is one of the most widely used products, used extensively in the building sector, automotive, agricultural and other areas where the steel needs to be protected from corrosion
Hot-Dip Galvanizing or HDG is a process in which zinc bonds to steel at the molecular level to produce a four-layer corrosion-resistant finish. The first three layers are zinc-iron alloy layers that are actually harder than the base steel. The fourth or top layer is pure zinc.

The main process of hot-dip galvanized steel coil is chemically degrease and electrolytically degrease the cold-rolled coil, clean the oil on the surface of the steel strip, and then anneal in a reducing atmosphere annealing furnace, and then immersed in a molten zinc pot for hot dip galvanizing. After smoothing, tensioning, and finally passivation or oiling and other post-treatment processes. The purpose of hot-dip galvanizing is to improve corrosion resistance and extend the service life of the material, while having an aesthetic surface and increasing the artistic effect.

Galvanized steel is a carbon steel that has been coated with zinc. The most common method of zinc coating is the hot-dip process. … When the material is removed from the zinc bath and cooled a reaction to the oxygen in the air occurs.

The reaction causes the zinc to become part of the steel (an iron-zinc alloy bond).

Many people know what galvanized steel is. It is used for a wide variety of applications ranging from HVAC ductwork to gardening pails; household decorations to garbage cans. The spangle finish on the surface makes it visually appealing, but also makes it more durable and corrosion resistant.

So, how is galvanized steel made? Where does that spangle come from? Well, let’s find out.
