Galvanized plate

Galvanized plate belongs to steel. The so-called Galvanized plate is a layer of zinc plated on the surface of the steel sheet, which can prevent the steel sheet from corrosion and play a protective role, thus increasing its service life. According to different processing methods, it can be divided into hot-dipped galvanized steel, colored galvanized steel, electro-galvanized steel, single and double-sided differential galvanized steel, alloyed galvanized steel, stamped painted galvanized steel, alloy galvanized steel and so on.

Galvanized steel is hot rolled steel strip or cold rolled steel strip as a substrate, after continuous hot dip galvanizing process and produced, the product has a strong corrosion resistance, good surface quality, conducive to deep processing, economic and practical characteristics, used as a substrate for downstream products, galvanized steel is widely used in the construction industry: light steel keel, corrugated panels, ventilation ducts, floor load-bearing panels, movable rooms, factory roofs, housing, municipal engineering fence panels and so on. Home appliance industry, air conditioners, refrigerators, washing machines, microwave ovens, water heaters, computer chassis, solar energy and other home appliances shell and base plate, automotive industry: car body, outer plate, inner plate, base plate, doors, etc., furniture industry: closets, tables, bedside cabinets, filing cabinets, filing cabinets, shelves and other types of furniture rails, and other industries, storage and transportation, packaging, grain silos, chimneys, buckets, rosin barrels, galvanized pipe, beer fermentation Other industries, storage, packaging, grain silos, chimneys, water barrels, rosin barrels, galvanized pipes, beer fermentation tanks, power distribution cabinets, containers, fertilizer tanks, etc.

Common Galvanized plate specifications

1. Conventional specifications

Conventional specifications of Galvanized plate thickness is generally between 0.12-4.0mm and width is between 600-1500mm. Common models are SGCC, DX51D, etc.

2. cold rolled specifications

Cold rolled Galvanized plate thickness is generally between 0.5-2.5mm, width between 820-1250mm. The common types are SPCC, SPCD, SPCE, etc.

3. Hot Rolled Specification

The thickness of hot rolled Galvanized plate is generally between 1.2-10mm and the width is between 1000-1500mm. Common models are Q235, Q345, etc.

The recommended standard thickness, length and width of Galvanized plate and its allowable deviation. In general, the thicker the Galvanized plate the greater the allowable error, rather than a fixed 0.02-0.04 mm, the thickness deviation is also based on yield, tensile coefficient and other different requirements, the length and width deviation is generally in the range of 5mm , the thickness of the sheet is generally between 0.4-3.2 .

Galvanized plate specification considerations

1. The specification of Galvanized plate should be selected according to the use of environment and actual needs.

2. Galvanized plate should be transported and used to avoid scratching, collision and other damage.

3. The service life of Galvanized plate is related to the thickness and quality of its zinc layer, and attention should be paid to its maintenance and care.
