Application of Galvanized Steel Strip

Galvanized steel strip is widely used in the production of steel pipes or shaped steel, which are popular in construction, light industry, automobiles, agriculture, and commercial industries. Besides, it is also popular for commercial packaging materials.

1. Construction industry: building roofs, lightning, baffles, sidewalls, chimney, partitions, gutters, rain rails, rolling doors, heating pipes, greenhouse pipes, thermal insulation pipe shells, etc.
2. Light industry: it can be used in home appliance shells, civil chimneys, kitchen utensils, etc.
3. Automobile industry: Parts of large cars, trucks, trailers, luggage carts, refrigerated trucks, rims, garage doors, wipers, mudguards, fuel tanks, water tanks, bicycle frames, etc.
4. Other aspects: ideal for manufacturing various metal or mechanical products, such as box covers, electrical cabinets, dashboards, office furniture, spring blades, saw blades, etc.

What Is Galvanized Steel Strip?

Galvanized steel strip is a long and narrow sheet made with cold-rolled or hot-rolled steel. Through hot-dip galvanizing, a thick zinc layer is plated to offer a uniform surface. Also, after complex physical and chemical reactions, a corrosion-resistant zinc-iron alloy layer will be formed between the substrate and zinc molten bath. Generally, the steel strips are supplied in coils. According to the different base metals, you can find cold-rolled strips and hot-rolled strips.

How Are Galvanized Steel Strips Made?

At Wanzhi Steel, we commonly make steel trips from pre-galvanized coils. It contains three steps.

1. Pickling Process. It aims to remove rust, oil, and dirt on the steel surface to ensure that no nodules or bubbles are produced during the galvanizing process. After pickling, it is cleaned in a tank with ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride. It will make sure the surface is clean and smooth.

2. Galvanizing Process. After pickling, the substrate will be immersed in a bath of molten zinc at a high temperature for galvanizing. Some will be cleaned with ammonium chloride or zinc chloride aqueous solution first, and then go through the continuous annealing furnace before galvanizing.

3. Slitting Process. The galvanized steel coil will be slitted into strips as the width customers required. Then roll up into coils for sale. The zinc layer thickness is customizable to customer requirements. Generally, it will be not less than 50 g/m2.

Surface Treatment

The common surface treatment of galvanized strips includes passivation, pre-phosphating, and oiling. Passivation mainly refers to chromate passivation. It can change the structure and gloss of the zinc coating to improve its corrosion resistance and adhesion between the coating and the base metal. Adding some activators, such as fluoride, phosphoric acid, or sulfuric acid, is helpful to form a thicker chromate film after passivation. If you have special requirements, please let us know in advance.

How to Store GI Strips?

Although the galvanized steel strip has been zinc coated. But as a kind of metal material, it will rust if exposed to humid and acidic environments. There are two types of strips on the market, namely, electro-galvanized strips and hot-dipped strips. The zinc layer thickness of hot-dip galvanized steel is relatively thick, so it has strong corrosion resistance. So just make sure the storage environment is dry and ventilated. In addition, it must also be arranged neatly.

About GI Strip Price

The price will be different with raw materials, production technology, zinc coating thickness, and labor costs. That’s why factories in China often offer lower prices. But according to the industry standard, the sale price of steel products won’t be too higher or lower. As an experienced manufacturer, we advise that do not to rely on low prices to avoid being fooled. At Wanzhi Steel, we always provide great discounts for bulk orders.
