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.

Q:What's the material of ASTM A653 G30 galvanized sheet?
Galvanized steel sheet is to prevent the corrosion of steel plate surface and prolong its service life, and the surface of steel plate is coated with a layer of metal zinc. This kind of zinc coated steel plate is called galvanized sheet.
Q:Which is good, z15 grade steel plate and z25 grade steel plate?
Both Z15 and Z25 are the properties of steel against lamellar tearing. Their properties are marked by the fracture shrinkage index of tensile specimens in thickness direction (15 and 25 in Z15 and Z25 are the minimum values of fracture shrinkage)
Q:What are the problems encountered in the construction of steel sheet piles? How to deal with
Based on the soft, sometimes the construction was adopted into the adjacent pile phenomenon, measures is the number of adjacent piles are welded together, and in the application of play pile connected locking coated with butter and other lubricants to reduce resistance
Q:How to choose welding method for welding different plate and thick steel plate?
For welding efficiency:General welding or argon arc welding of thin plate, medium plate with gas shielded welding (such as two welding), thick plate with submerged arc welding (usually not groove, single-sided, once the penetration of up to 20mm).
Q:Will the plating steel be rusty? Will it rust when touching the water?
Galvanized steel plate as long as the plating is good, the surface coating does not fall off, will not rust, often see electroplating parts rust, because the coating is formed.
Q:The difference between steel edge sealing strip and steel plate putty water stop belt
The good bonding between galvanized steel sheet and concrete makes the waterproof performance better. The utility model relates to a steel edge rubber water stop strip, which is characterized in that a water stopping product is adopted, which adopts a non equal thickness structure, a strong strength area and a waterproof zone, and makes the parts of the utility model be uniform and reasonable in force. The utility model relates to a steel edge rubber water stopping strip, which is additionally provided with an installation hole and is connected with the steel bar. The utility model has the advantages of firm fixation, easy displacement, and uniform and reasonable force for each part. When the utility model is in construction, the clamping surface of the clamping plate of the utility model is large and is not easy to be dislocated; the steel plate is additionally provided with an installation hole and is connected with the steel bar; the utility model has firm fixation and is not easy to displace. Good adhesion between galvanized steel sheet and concrete, and steel rubber stop makes waterproof better. A waterproof products produced by our factory in the buried steel edged waterstop is combined to galvanized steel and natural rubber raw material consisting of a rubber body material, it adopts the aging of natural rubber and excellent antioxidant performance, with strong self adhesive; high temperature in summer has no flow, low temperature in winter not the crisp; and has excellent water resistance, acid and alkali resistance and aging resistance; long service life, the product itself is non-toxic, the characteristics of a good environment.
Q:What is the difference between color steel plate and hot galvanized sheet?
Color steel plate is divided into two kinds, one is hot galvanized after spraying color, not a hot galvanized plate directly after spraying, hot galvanized and color steel plate is a kind of anti-corrosion measures, galvanizing after spraying outdoor powder, not only has good antiseptic effect, and the color is beautiful, just hot galvanized plate no antiseptic, decorative effect
Q:What's the effect of water stopping between steel plate and water stop strip? What's the difference between the process and the sealing process?
Water swelling, water stop, rubber water stop and water stop steel plate are compared between the three:After using the water stopping strip (water stopping steel plate and water stop bar), the water can be prevented from soaking through the concrete, and the double protection function of water proofing and water stopping can be realized.
Q:Is PCM steel better than galvanized steel?
Color plate refers to the color coated steel plate, color coated steel plate is a kind of organic coating plate.PCM color steel plate positive general selection of linear polymer oil free polyester resin paint, add amino resin and special catalyst design,
Q:What is reinforced steel plate?
Dimension refers to the thickness, width, length of a steel plate
