Galvalume steel coils are of course also very common in our lives. Because its advantages are quite prominent, more people choose to use it. Today I would also like to take this opportunity to introduce to you the precautions for using aluminum-plated magnesium-zinc sheets? If you want to know, come and take a look.
Galvalume steel coil
There is a lot of basic information that we need to know before using galvanized steel coils. After all, there are many knowledge points involved. The use of galvanized steel coils has many excellent properties, namely 33360 has extremely strong corrosion resistance, which is 3 times that of pure galvanized steel sheets; the surface has a beautiful luster and can be used as exterior wall panels of buildings. Corrosion resistance The corrosion resistance of "aluminized steel coil" is mainly due to aluminum and its protective effect. What you need to know at this point is that when the zinc is worn away, the aluminum will form a dense layer of aluminum oxide that prevents the corrosion-resistant material from corroding the interior. Heat-resistant aluminum-zinc alloy steel plate has good heat resistance and can withstand high temperatures above 300 degrees Celsius. In fact, the use of galvalume-coated steel coils is similar to the high-temperature oxidation resistance of aluminized steel and is often used. Chimney pipes, ovens, electric lamps and fluorescent lampshades. Heat-reflective galvanized steel sheet has a high heat reflectivity, which is twice that of galvanized steel sheet, a commonly used insulation material. Economical Because 55% AL-Zn has a lower density than Zn, its weight is 3% or more greater than the surface area of galvanized steel when using Al-Mg-Zn. Same as gold plating.
Galvanized steel coils should be stored indoors such as warehouses to keep them dry and ventilated, and should not be placed in an acidic climate for a long time. When storing outdoors, protect it from rain to avoid oxidative discoloration caused by condensation. When transporting galvanized steel coils, attention must be paid to avoiding external impacts. SKID is required to support the steel coils on the transport vehicle to reduce stacking and rain measurement. When working, use the same lubricant as the aluminum plate. When it is necessary to drill holes or cut galvanized steel sheets, the scattered iron sheets must be cleared away in time. In addition, everyone needs to pay attention to using galvanized color plates with caution in alkaline medium conditions; damp wood and concrete should not be in contact with galvanized plates for a long time; small batch testing to prevent poor link performance; or read. The use of galvanized steel coils should prevent the anti-grain film from turning black due to moisture and high temperature during processing and stacking; if processing, storage, transportation, etc. are prone to surface scratches and other problems, it is recommended to use peritoneal treatment; electrical cabinets are processed and produced Passed bending test before.
