Hot-dip galvalume steel plate is also called aluminum-zinc coated plate, aluminum-zinc natural color plate, aluminum-zinc fingerprint-resistant plate, aluminum-zinc light plate, because the surface coating of the plate is an alloy composed of aluminum, zinc and other trace elements. , with outstanding performance in terms of corrosion resistance, gradually replacing galvanized sheets. Galvalume sheets are mainly used in steel structure roofs, walls, switch cabinets, and home appliance panels.
The difference between galvalume plate and profiled steel plate is as follows: galvanized plate is 99% aluminum-plated, while galvanized plate is generally divided into 5% galvanized and 55% galvanized. Aluminum zinc plating is slowly developed on the basis of pure zinc plating. 5% and 55% refer to the aluminum content.
Hot-dip galvanized steel sheets, hot-dip galvalume steel sheets, or aluminum sheets and cold-rolled sheets are steel sheet substrates that are not painted or baked. The above types of steel sheets are the base sheets of color steel sheets. Each steel sheet has its own advantages and performance. 1: Hot-dip galvalume steel plate; this base plate has good impact properties and good elongation and yield value. The color steel plates produced in this type
According to foreign experience and specifications, the anti-corrosion coating of the base material of general profiled steel plates (pit plates) should be no less than hot-dip galvanized 350g/㎡ (Z35) or hot-dip galvanized 185g/㎡ (AZ185). As a building structure, cold-rolled The hot-dip galvanizing Zinc/Galvanizing specification for steel sections and floor slabs is 275g/㎡ (Z27), and the requirement for coastal exposed parts is 350g/㎡ (Z35).
Plate thickness: 0.5mm0.60mm. Base color plate: hot-dip galvanized ≥ AZ150 steel plate. Strength: 235Mpa345MPa. Performance features: The unique 360-degree double-lock curling process produces the most sealed upright fastening seam to ensure the best climate temperature Tightness; adding preset sealant to the fastening seam can prevent leakage in any harsh climate;
