The surface of Zn-Al-Mg steel sheet presents a unique smooth, flat and gorgeous star flower pattern, and the base color is silver-white. The special coating structure makes it have excellent corrosion resistance. Compared with garden beds made of other materials, Zn-Al-Mg steel steel sheet has the following advantages:
Zn-Al-Mg steel sheet has strong corrosion resistance, and its normal service life can reach 25 years, which is 3-6 times longer than galvanized sheet and is equivalent to steel. The corrosion resistance of aluminized zinc sheet comes from the protective layer maintenance function of aluminum and the dedication maintenance function of zinc. Zn-Al-Mg alloy steel coils have been exposed to outdoor exposure tests for more than 20 years in a variety of different atmospheric environments. It has been verified that 55% Zn-Al-Mg steel has a cutting edge maintenance function, which is better than galvanized steel and 5% Zn-Al-Mg steel. better. Under what environment will the corrosion of galvanized steel accelerate? It is well known that corrosion will accelerate in an acidic environment, but most of the garden soils we use are neutral, so there is almost no effect.
Most metals will heat up in the sun, which will cause crops to grow poorly. However, this problem will not occur for Zn-Al-Mg steel, because Zn-Al-Mg steel has a high degree of heat reflectivity, which makes it possible to provide a relatively constant temperature environment for plants and soil; It has excellent heat resistance and can be used in high temperature environments up to 315 degrees.
Zn-Al-Mg plated steel sheet has outstanding processing functions and can be stamped, cut, welded, etc. The coating has good adhesion and impact resistance.
