General Information Of Hot Dip Galvanized Steel Coil

Hot-dip galvanized steel coils are available with a pure zinc coating through the hot-dip galvanizing process. It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hot-dip process is the process by which steel gets coated in layers of zinc to protect against rust. It is especially useful for countless outdoor and industrial applications.

Application Of Hot Dip Galvanized Steel Coil

Production of cold formed corrugated sheets and profiles for roofing, cladding, decking, tiles, sandwich walls, rainwater protective systems, air conditioning duct as well as electrical appliances and engineering

With GI as base metal, after pretreatment (degrease and chemical treatment) and liquid dope with several layers of color, then after firing and cooling, finally the plate steel is called pre-painted galvanized steel. Pre-painted galvanized steel is good capable of decoration, molding, corrosion resistance. It generally displays superior workability, durability and weather resistance.

Q:Aluminum alloy rolling doors and color steel shutter door that good
Hello, the shutter door material mainly galvanized steel plate, color steel plate, aluminum alloy, stainless steel, PVC soft board, PVC soft door curtain.
Q:What are the characteristics of hot-rolled steel coils and cold rolled steel coils? What loading and unloading tools should be used? What items should be paid attention to?
When placing materials to roll on both sides of the main pad wood pallets, prevent rolling back and forth. In addition the floor should be thickened, cannot have uneven or debris, because the line of steel coils when gravity concentrated in contact with the ground floor, there is a fracture easily, debris, easy to leave the indentation in the steel roll.
Q:What brand steel tapes are of good quality?
Durable durable depends on your personal use frequency, the high frequency nature is easy to wear, resulting in scale. If you like fuzzy units if buying tape need verification it is best to buy the Great Wall Seiko goods, because the time to measure the number of verification inspection of steel tape, basically qualified rate of the Great Wall Seiko steel tape can reach one hundred percent.
Q:The difference between aluminized color steel roll and ordinary color steel roll
Substrate selection: AZ150 (aluminum zinc content 150g/m2); G345A high strength galvanized steel sheet (55% aluminum, 43% zinc and 1.6% silicon) corrosion resistance data: 5%NaCL 35 DEG C, 1000Hrs, Field good, Scribe, No, Blister, 2mm belowQ.U.V: 2000hrs, MAX.2 color, light to keep the rate above 90%, the above data show that aluminum zinc coated board (AZ150, G345A, PVDF) is very suitable for the extreme environment of buildings or other facilities, highly corrosion resistance and weather resistance, and the major steel plate can ensure the service life of 20 years. In addition, high strength steel has been widely used abroad, and it has good economic performance, and it is also the domestic development trend.
Q:How can the outer diameter and weight of steel coil be converted?
To obtain the outer diameter of the steel coil is calculated according to the density of 7850, according to the density, in general, hot-rolled is 0. 96~0, 98, cold rolled, according to 0. 98~0. Ninety-nine
Q:What is the accuracy of steel tape inspection
In addition, the project is through the detection of steel tape, steel tape each batch have the error him different, so do projects each into a batch of steel tape has to go through the inspection department, let this batch of steel tape has reached the same error range. All the measuring tools in this project are unified into these steel tape measures, so that the measurement error is guaranteed
Q:Why can hot rolled coils be placed outside?
Because hot-rolled steel coils are generally used as raw material for semi-finished products, they have to be further used for pickling and cold rolling to make more use. The rust and dust can be removed after pickling
Q:Where are the coils and the steel plates used? Where did the steel plate come from?
Steel plate is divided into many kinds of PU, low alloy, boiler plate, vessel plate, high strength plate, etc..
Q:A roll of 1 meters wide color steel roll about how many tons?
In general, between 3.5 and 5 tons. Our company uses 0.17*1000 white color steel roll. The weight is usually around 4.5 tons. Different manufacturers will have different sealing rolls.
Q:What's the length of a coil of cold rolled steel? Is there a standard?
But in the process of production, not the large volume, a few kilometers long have. The small volume sold by the finished product is much shorter.
GZTSTEEL is a modernized non-government enterprise. We keep science and technology as the impetus for the development of our company. Our products include high-precision hot galvanized steel sheet (coils), hot-coating Al-Zn-Si steel sheet (coils), and Prepainted steel sheet(coils) and equipment. We have integrated both manufacture and sale.
