Shandong Hengze New Material Co., Ltd. is a China aluminum zinc steel coil factory. As a supplier with own China aluminum zinc steel coil factory, We are very familiar with China aluminum zinc steel coil, let’s talk about it.
Aluminum-zinc steel coil/plate (GL coil, Galvalume steel AZ 150g) is the basis of the Galvanized steel coil, also including the 55% aluminum.
The total global production of the Galvalume steel coil/plate has reached 24 million tons since it entered the practical stage in 1972, and the current annual output is about 3 million tons.
30 ~ 35% of aluminum-zinc coated steel is used for the ceiling, wall, etc. Besides being a trademark of BIEC, the aluminum-zinc plate is also registered and licensed by BIEC for the following products:
Aluminum-zinc plated steel coil/plate has a distinctively smooth, flat and gorgeous star – white base. Special coating structure makes it has excellent corrosion resistance. Aluminum-zinc plate with normal service life can be up to 25 a, good heat resistance, can be used in the high temperature of 315 environments; Good adhesion between the coating and paint film, with good processing performance, can be stamping, cutting, welding, etc. The surface is very conductive. The high-quality aluminum zinc steel coil factory price is also very reasonable.
China aluminum zinc steel coil coating is composed of 55% aluminum, 43.4% zinc and 1.6% silicon by weight. The process of aluminum-zinc plating is similar to that of galvanized steel and aluminum plating. When exposed to the same environment on both sides, 55% al – Zn alloy-coated al – in steel has superior corrosion resistance. The aluminum-zinc coated steel plate with 55% al – Zn alloy coating not only has good corrosion resistance but also has excellent adhesion and flexibility.
The corrosion protection layer must be applied to the surface of the steel plate because it will produce rust corrosion when exposed to moisture. Generally, the corrosion protection layer is divided into hot-dip Zn and hot-dip Al-Zn alloy (the composition of the Al-Zn alloy is 55% of aluminum, 43.5% of zinc and 1.5% of silicon, referred to like 55% all-in). According to the data, 55% al – in combined corrosion resistance is 4 times of the same thickness.
According to the experience of the foreign specifications, generally pressed steel plate (pit) the base material of anticorrosive coating shall be not less than 350 g/O hot-dip galvanized (Z35) or hot dip aluminized zinc 185/150 g/O(AZ185/150)
As a cold-rolled steel building structure, the lowest floor of hot-dip galvanized layer any Zinc/Galvanizing specification of 275g/O(Z27), coastal exposed parts requirement of 350g/O(Z35).
1. Thermal reflection: Aluminum – and zinc-coated steel, which is often used as an insulating material, has a high thermal reflectance, twice that of galvanized steel.
2. Heat resistance: Aluminum-zinc alloy steel has a good heat resistance and can withstand temperatures of more than 300 degrees Celsius. Similar to the high-temperature oxidation resistance of aluminized steel, it is often used in chimneys, ovens, illuminators, and solar lampshades. Corrosion resistance:
The corrosion resistance of aluminized zinc steel coil is mainly due to the protection function of aluminum. When zinc is worn, aluminum forms a dense layer of alumina, preventing further corrosion of the corrosion-resistant material inside.
3. Economy: Since the density of 55% Al-Zn is smaller than that of Zn, the area of aluminum and zinc-plated steel is more than 3% larger than that of plated steel with the same weight and the same thickness.
4. Easy to paint on: There is excellent adhesion between the aluminum-zinc plate and the paint, which can be applied without pretreatment and weathering.
Aluminum-zinc plate coating is more excellent adhesion, so without Weathering and another pretreatment, it can also be directly on the advertising board and general plate coating.
The Aluminized zinc plate has a silver-white gorgeous surface.
5. Processing and spraying: Aluminum-zinc plating steel sheet and galvanized steel sheet have similar processing performance and spraying performance.
Architecture: roof, walls, garage, soundproof walls, plumbing, and modular housing
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 belt, LED backlight, electric gas cabinet, etc.
Others: thermal insulation cover, heat exchanger, dryer, warm water, etc.
The difference between a galvanized sheet and aluminum zinc plate mainly lies in the difference of the plating layer. The surface of the galvanized sheet is evenly distributed with a layer of zinc material, which plays an anodic protection role to the parent material. In other words, the substitutive corrosion of zinc material protects the use of the parent material.
Aluminum zinc plate the surface of the coating is composed of 55% aluminum, 43.5% of the zinc and small amounts of other elements, aluminum zinc plating coating under the microscopic surface for a honeycomb structure, composed of aluminum in the “honeycomb” containing zinc, in this case, aluminum zinc plating coating have anodic protection role, but on the other hand due to the shrinking of zinc content on the one hand, because of the zinc material by aluminum bag not the role of electrolysis anode protection so greatly reduced, so once the aluminum-zinc plate is cut, the cut off the edge of the protection of basic loss was will soon be under the condition of corrosion, so the plating aluminum zinc plate should be cut less as far as possible, Once cut, apply rust-proof paint or zinc-rich paint to protect the edge, can make the plate life extension.
