In modern construction and industrial fields, the choice of materials is crucial. Hot-dip galvanized steel sheet, as a product of surface treatment technology, has become the preferred material for many engineering projects due to its excellent corrosion resistance and economy. This article will take you to an in-depth understanding of the characteristics and applications of hot-dip galvanized steel sheet.

What is hot-dip galvanized steel sheet?

Hot-dip galvanized steel sheet, also known as hot-dip galvanized steel sheet, is produced by hot-rolled steel strip or cold-rolled steel strip as the substrate through a continuous hot-dip galvanizing process. The zinc layer on its surface can prevent the surface of thin steel sheet and steel strip from corroding and rusting. Generally, the thickness of the hot-dip galvanized layer is about 60um, the zinc layer is thicker, the adhesion is strong, and the zinc layer is not easy to fall off. The minimum galvanizing amount is 40-60g/m2, and the maximum is 600g g/m2.

Hot-dip galvanized steel sheet can be divided into hot-rolled galvanized sheet coil and cold-rolled hot-dip galvanized sheet coil.

Common steel types for hot-dip galvanized sheets include: general commodity rolls (CQ), structural galvanized sheets (HSLA), stamped galvanized sheets (DQ), deep-drawn hot-dip galvanized sheets (DDQ), bake-hardened hot-dip galvanized sheets (BH), dual-phase steel (DP), TRIP steel (phase transformation induced plasticity steel), etc.

Features

Strong corrosion resistance, good surface quality, conducive to deep processing, economical and practical, etc.

Application areas

1. Construction industry: used for roofs, walls, balconies, etc., to provide lasting protection.

2. Automobile manufacturing: used for body and chassis to enhance the durability of vehicles.

3. Home appliance industry: used for the shells of home appliances such as washing machines and refrigerators to improve the corrosion resistance of products.

4. Agricultural machinery: used for tractors, harvesters, etc. to withstand harsh outdoor environments.

Hot-dip galvanized steel sheets have become one of the indispensable materials for modern industry with their excellent performance and wide application. Whether in the fields of construction, automobiles or home appliances, hot-dip galvanized steel sheets are an ideal choice for improving product performance and extending service life.
