The building materials of the steel structure included Galvalume coils, and Colored coils. Metal building materials are used for the basic building structure and are used as a wall and roof for steel structures.
It uses slabs (especially continuous casting slabs) as materials, and after heating, makes a strip metal from the grinding units and finishing units.
The hot metal wire from the final rolling machine is cooled to a temperature set by the laminar flow and then rolled into a metal wire.
Depending on the different needs of the users, the cool steel line goes through different ways of completing the lines (measuring, straightening, reversing or cutting, checking, measuring, packing and marking, etc.), processing into steel plates, flat coils and cutting strip products.
It is commonly used in the steel industry, which differs from the hot-rolled coil. It referred to a line of thick metal and rolled into a coil through a window in a heated room. Compared to hot rolled coils, the top of the folded coils is lighter and smoother, but will create more internal stress. Anneal insertion is usually done after a cold wrap.
Galvanized refers to the advanced therapeutic technology of attaching a layer of zinc to metals, alloys, or other materials that will play a role in beauty and prevent corrosion. The main method used today is hot-dip galvanizing.
The manufacturing process of a hot-dip sheet metal includes mainly: real sheet preparation → pre-filtration treatment → hot-dip filtration → post-filtration treatment → finished product testing, etc.
Traditionally, it has been based on pre-purification treatment.
Galvalume steel is an aluminum-zinc alloy structure, consisting of 55% aluminum, 43% zinc, and 2% silicon reinforced at temperatures above 600 ° C. The entire structure is made of aluminum-iron- Silicon-zinc. This alloy forms dense quaternary crystals.
Strong corrosion resistance
It is three times the size of pure metal, and the top has beautiful zinc flowers, which can be used as building exterior panels.
Resistance to corrosion of galvalume steel coils is mainly due to the protective function of the aluminum. When zinc is applied, aluminum forms a thick layer of alumina to prevent corrosion-resistant materials from further corrosion.
Galvalume steel plate has excellent heat resistance, can withstand temperatures above 300 degrees Celsius.
The hot light of the galvalume steel sheet is very high, twice as much as the galvanized steel sheet. People often use it as a heat sink.
Because the density of 55% AL-Zn is less than the weight of the Zn, less than the same weight and the same thickness of the refining layer, the galvalume steel plate area is 3% larger than the extracted metal.
Colored steel coils are covered with various colors of natural holes.
In addition to the zinc layer protection, the colored metal adhesive line uses a dipped hot metal fiber as a base cover.
It protected the metal sheet from corrosion of metal. The lifespan of 1.5 times the use of mineral steel.
Colored trucks have low weight, good appearance and excellent anti-corrosion performance, and can be processed directly. They are widely used in the construction industry, the home electronics industry, the electronics industry, the furniture industry, and the transportation industry.
Coats used for colored coils should choose an environment suitable for the environment, such as polyester silicon modified polyester, polyvinyl plastisol, polyvinylidene chloride, etc. Users can choose according to purpose.
