cold rolled hot dip galvanized steel coil/

Galvanized steel coils are widely used in the construction industry, as raw material for the production of corrugated panels, fencing products, drywall panel profiles, ventilation systems etc. Recommended for both outside and inside usage, galvanized steel has a high resistance to corrosion in different environments, due to a protective layer of zinc of 100 – 180 grams per square metre.

Hot-dip galvanized steel coils are produced by immersing steel in a zinc bath. An appropriate galvanizing process requires a pretreatment process during which the steel passes through different baths which prepare the surface for zinc coating. In this stage, chemicals are used to clean the surface of the steel. After the chemical treatment, the steel coils pass through a bath of melted zinc at temperatures around 460 ° C. The resulting uniform coating is finished through a process of skin-passing to provide smooth and shiny appearance of the finished product. To store for a longer period, the hot-dip galvanized coils can be delivered with a final oil coating, according to the customer’s demand.

PROFILAND STEEL produces hot-dip galvanized steel coils with very good workability at further cold forming and bending processes.

Technical specification for the hot-dip galvanized produced by PROFILAND STEEL::

• Steel grade: DX51D+Z• Zinc coverage: 30-180 g/sqm on both sides (depending by the requested specification);• Thickness: between 0,2 mm and 1,00 mm;• Width: 600mm,914mm,1000mm, 1220mm and 1250 mm;• Coil weight: 4-6 mt;• Coil ID: 508 mm;• Coil OD: 900-1500 mm ;

Depending on their usage, the hot-dip galvanized coil can be delivered slightly oiled.

Q: Can Caoyan sandwich wall be installed? How to install Thank you: With steel frame or stainless steel, but the cost is high, it is best to use the general public canopy affordable.

Q: Can polyurethane sandwich panels be used for cold storage?: Yes. Polyurethane cold storage board is a good insulation of lightweight polyurethane as the inner material, the external by the SII, PVC color steel plate and stainless steel plate made of polyurethane sandwich panels, the advantage of doing so is to prevent cold storage board because of the large temperature difference between inside and outside The temperature of the spread, so that the cold storage more energy-efficient, improve the efficiency of cold storage. Luoyang Tianjiang chemical production of polyurethane cold storage board also has fire, flame retardant and high temperature and other excellent features.

Q: Purification workshop manual sandwich board how much money to install a square can do: You search under the Suzhou Jinjiaba town and Zhenze town side of the factory, cheaper.

Q: Sandwich composite panel and color steel tile difference which the high cost: Sandwich panels are also called Caigang sandwich panels, is the middle of two-layer steel plate plus polyurethane foam or rock wool building plate; color steel tile is a single layer of pressure plate. Sandwich panels are more expensive.

Q: How to calculate the force of the sandwich panel: Are generally estimated that we are doing this. Do not know how to calculate, but how many people we have to do the number of board

Q: What is the glue used in color steel sandwich panels?: One component, two component ~

Q: Sandwich board formaldehyde excessive fine how much: You do not want to fine, and hurry up and then do good relations with the department, otherwise you do not exceed the standard will be fined.

Q: I have a small shed, want to use sandwich panels construction, how can the summer 40 degrees with air conditioning to save power: Wall plug a layer of sandwich panels no problem, but the window and sandwich panels to achieve the same insulation effect is difficult!

Q: Polyurethane sandwich panels in the polyurethane is what material, what are the benefits of industrial building materials should choose polyurethane?: Polyurethane is a two-component AB material (isocyanate and combined polyether) mixed foam, is the thermal insulation material in the lowest thermal conductivity of 0.017 ~ 0.024 (thermal conductivity of the lower the better insulation). Polyurethane sandwich panels used in the filling process of polyurethane, pre-made pre-insulation board directly installed on-site use. If your plant area is relatively large, it is recommended that you only use the whole color plate, and then use the field of polyurethane spray foam process, this process than the infusion process is the advantage of spraying seamless, better insulation. The cost is still lower than the infusion process.

Q: We are the construction unit to the scene into the decoration with the sandwich panels and fire retardant coating supervision requirements were re-test and then also use a good brush-resistant paint sandwich panels to do re-examination Will this want to detect what the purpose of what is the detection of the project. Good people to help answer Thank you: The purpose of the test is whether the material meets the design requirements The item is refractory grade
