Product Description

Hot dip Galvanized sheet is supplied with rectangular plate after cross cutting; Hot dip Galvanized Coil is mainly used in construction, household appliances, automobile, container, transportation and home industry. Especially in steel construction, automobile manufacturing, steel warehouse manufacturing and other industries. Hot dip galvanized sheet is supplied with rectangular plate after cross cutting; Hot dip Galvanized coil supplied in coil shape after coiling. Galvanized sheet coil is produced by continuous hot-dip Galvanizing process with hot-rolled steel strip or cold-rolled steel strip as substrate. Commonly used thickness is 0.25mm-3mm, width is 1000mm-1250mm-1500mm. Their main characteristics are: strong corrosion resistance, good surface quality, benefit from deep processing, economic and practical.

Our markets mainly are Middle & South America, Southeast Asia, the Middle East and Africa, covering nearly 30 countries and obtaining a well-deserved reputation from clients around the world

Classification of galvanized reel substrate

Hot dip galvanized substrate: The organic coating on the hot dip galvanized steel plate to obtain the product is hot dip galvanized color coated plate. In addition to the protective effect of zinc, the organic coating on the surface also plays the role of isolation protection and rust prevention, and the service life is longer than that of hot galvanized sheet. The zinc content of hot-dip galvanized substrate is generally 180g/m2 (double-sided), and the maximum zinc content of hot-dip galvanized substrate used for external construction is 275g/m2.

Hot aluminized zinc substrate: The hot aluminized zinc steel plate (55%Al-Zn) is used as the new coating substrate, usually containing 150g/m2 aluminum zinc (double sided). The corrosion resistance of hot - plated aluminum zinc plate is 2-5 times that of hot - plated zinc plate. Continuous or intermittent use at temperatures up to 490ºC will not cause severe oxidation or oxide skin. The ability to reflect heat and light is twice that of hot-dip galvanized steel plate, and the reflectance is greater than 0.75, which is the ideal building material to save energy.

Electroplated zinc substrate: electrogalvanized plate for the substrate, coated with organic coating baking products for electric galvanized color coated plate, because of the thin zinc layer of electrogalvanized plate, usually zinc content is 20/20g/m2, so the product is not suitable for use in outdoor production of walls, roofs, etc. But because of its beautiful appearance and excellent processing properties, it can be mainly used in household appliances, audio, steel furniture, interior decoration, etc.

Characteristics of galvanized reel substrate

Electroplated zinc substrate: the coating is thinner, corrosion resistance is not as good as hot dip galvanized substrate

Hot dip galvanized substrate: the thin steel plate is immersed in the melted zinc groove, so that the surface adhesion of a layer of zinc, this galvanized plate has good coating tightness and weldability

Hot aluminized zinc substrate: The product is plated with 55% Al-Zn, has excellent corrosion resistance, its service life is more than four times that of ordinary galvanized steel plate. It is the replacement product of galvanized sheet

Type of galvanized coil

Polyester (PE): Good adhesion, wide range in formability and outdoor durability, moderate chemical resistance, low cost

Silicon modified polyester: namely (SMP), the coating has good hardness, wear resistance and heat resistance, as well as good external durability and powder resistance, luster retention, flexibility, medium cost

High durability polyester: namely (HDP), excellent color retention and UV resistance, excellent outdoor durability and powder resistance, good film adhesion, rich color, excellent cost performance

Polyvinylidene fluoride: namely (PVDF), excellent color retention and UV resistance, excellent outdoor durability and powder resistance, excellent solvent resistance, good formability, dirt resistance, limited color, high cost
