1.5*1220*2440 gi steel sheets mainly use for constructions steel structure ,prefab buildings decking floor .our products have higher zinc coating 120-275gsm ,high tensile and yield strength,ASTM A653 steel grade , 30 years wanrranty .

According to production methods, seamless steel pipes can be divided into: hot-rolled seamless pipes, cold-drawn pipes, precision steel pipes, hot-expanded pipes, cold-spinned pipes, and extruded pipes.

Golden color PPGI slittings are based on prepainted hot-dip galvanized sheets,prepainted aluzinc steel,zinc coated steel ,electro-galvanized sheets, etc. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic coatings are applied on the surface, and then The product is baked and cured.

55% Alu GL COILS galvalume steel sheet is composed of aluminum-zinc alloy structure, which is composed of 55% aluminum, 43.5% zinc and 1.5% silicon solidified at a high temperature of 600°C. Its entire structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary crystal An alloy .The corrosion resistance of "aluminized zinc steel coil" is mainly due to the protective function of aluminum and aluminum. When zinc is worn, aluminum forms a dense layer of aluminum oxide, which prevents corrosion-resistant substances from further corroding the interior.

Fingerprint resistant GL steel sheet is an alloy coated steel sheet widely used in many fields such as building materials, home appliances, automobiles, environment, machinery, and ships. The galvanized steel sheet is covered with aluminum-zinc alloy on the surface of the steel sheet. RFP GL Coils is composed of 55% aluminum, 43.5% zinc and 1.5% silicon solidified at a high temperature of 600°C. The entire structure is composed of aluminum-iron-silicon-zinc, forming a dense An alloy-coated steel plate of quaternary crystal.
