AS1397 G550 Galvalume Steel Coil 55% AL-ZN Regular Spangle Structural Steel Grade

AS1397 G550 structural steel grade AFP Aluzinc Steel Galvalume Steel Coil 55% AL-ZN Regular Spangle

Aluminium-zinc-steel plated light steel has quite a few excellent characteristics: Strong corrosion resistance, 3 times that of pure galvanising; beautiful zinc flowers on the surface, can be used as building roof exterior panels. Abbreviation AZ150, aluminium-zinc-steel plates keel for a long time without colour change on the bare surface, such as chemical corrosion, the surface of the physical reaction occurs, the formation of aluminium protective film on the surface of the keel, so that the outside world of chemical substances and the keel separated from the separation of the keel, to protect the keel of the main body of the material, to prevent rusting.

Corrosion resistance is mainly because of aluminium, the protective function of aluminium. When the zinc is abraded, aluminium forms a dense layer of aluminium oxide, preventing the corrosion-resistant substances from further corroding the interior.

Aluminium-zinc-steel-plated alloy steel coils have been subjected to more than 20 years of outdoor exposure tests in a variety of atmospheric environments, confirming that aluminium-zinc-plated steel sheets provide much better protection for cut edges than galvanised steel sheets.

Aluminium zinc steel plating: AZ150 for short, aluminium zinc plating is galvanized corrosion 2-6 times, aluminium zinc plating keel long-term naked surface has no colour change, such as in the case of chemical corrosion, the surface of the physical reaction occurs on the surface of the keel to form a protective film of aluminium, so that the outside world of the chemical substances and the keel separated from the separation of the keel to protect the keel of the main body of the material, to prevent rusting.

Aluminium zinc plating: aluminium zinc plated light steel has a number of excellent characteristics:

(1) strong corrosion resistance, 3 times that of pure galvanised; (2) beautiful zinc flowers on the surface, which can be used as a building exterior panels.

Abbreviation AZ150, aluminium-zinc-plated keel for a long time without colour change on the bare surface, such as chemical corrosion, the surface of the physical reaction occurs, the formation of aluminium protective film on the surface of the keel, so that the outside world of chemical substances and the keel separated from the separation of the keel, to protect the keel of the main body of the material, to prevent rusting.

Corrosion resistance is mainly because of aluminium, the protective function of aluminium.

When zinc is abraded, aluminium forms a dense layer of aluminium oxide, preventing further corrosion of the corrosion-resistant material inside.

Aluminium-zinc plated alloy steel coils have been subjected to outdoor exposure tests for more than 20 years in a variety of different atmospheric environments, confirming that the protective function of aluminium-zinc plated steel sheets with cut edges is much better than that of galvanised steel sheets.

Heat reflectivity: Aluminium-zinc-plated mild steel has a high thermal reflectivity, twice that of galvanised mild steel, and is often used as a thermal insulator.

Application:

Buildings: roofs, walls, garages, soundproof walls, pipes, and modular houses, etc

Automobile: muffler, exhaust pipe, wiper accessories, fuel tank, truck box, etc

Home appliances: refrigerator backplate, gas stove, air conditioner, electronic microwave oven, LCD frame, CRT explosion-proof strip, LED backlight, electrical cabinet, etc

Agriculture: pig houses, chicken houses, granaries, greenhouse pipes, etc

Others: heat insulation cover, heat exchanger, dryer, water heater, etc.

Shandong Decho Building Materials Technology Co., Ltd (hereafter called “DBM” ) is a professional manufacturer and exporting company of coated steel coils and sheets, with over 13 years of experience in steel industry and 11 years of steel mill work experience, with extensive product knowledge and experience in production process, especially for the supply of coated steel coils with a stable and reliable supply chain of manufacturers and logistics.
