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: What kind of support is needed: Fix the screws on the C steel

Q: What is the current project wall, which kind of roof? There are commonly used models: Sandwich board consists of three parts: the upper and lower two forming steel plate, the middle of the core board (with rock wool, polystyrene, polyurethane) thickness of 50mm / 75mm / 100mm, both sides of the strip. Mainly used for the activities of the wall panels and roof panels, and a variety of large factories. The color pressure plate is an integral part of the sandwich panel, that is, the upper and lower forming plates. Generally used for site Wai block, warehouse panel. The model wall is made of 950 rock wool wall sandwich panel composite board, roof 960 rock wool roof sandwich panel

Q: Build a color steel sandwich panel production plant how much money: The general machine price of 25 million or so, the venue costs plus how much raw materials you need, you can run the general about 100 million, but the funds to return to the fast, can not have too much debt.

Q: How about the sound insulation of the sandwich panel?: Insulation material does not have the same frequency of noise barrier effect is not the same, impermeable to prevent the snow from the inside into the Caigang sandwich panels. Snow is important to pass through the gap or node into the color steel sandwich panels. To achieve the performance of anti-seepage, the need to use the sealing ring in the screw seal after the adoption of hiding-type flow, the overlap in the board with a sealant or riveting solution. Because of the variety of metal sheet roofing, color steel sandwich panels from heavy public buildings to the plant, Caigang sandwich panels sound insulation to a sound insulation coefficient a. 8% annual increase in the progress of Caigang sandwich panels after the installation of the roof without access to the mouth, steel structure with energy saving, environmentally friendly recyclable, Caigang sandwich board confidence that few people can see on the spot.

Q: Introduction of foam sandwich panels: Foam sandwich panels beautiful appearance, bright color, the overall effect is good, it sets load, insulation, waterproof in one, and no secondary decoration, is a wide range of uses, especially in the construction site for temporary facilities such as office, Wall, etc., but also reflects the modern construction site of civilized construction, especially in the rapid installation and put into use, can be installed in the removable, material turnover index, there are obvious advantages, a substantial reduction in temporary construction site costs, Will be indispensable for new lightweight building materials.

Q: Which color plate sandwich board price is low and good insulation: If you are building a house, Henan Tianfeng Group has a new energy-saving sheet, called polyurethane, is the kind of material used in the refrigerator, it can be said that the best insulation, and hope to help you.

Q: Are thermocol roof insulation boards or thermocole sandwich concrete bricks durable?: I typed in thermocol and this is what it gave me. Hope it helps. polystyrene (p?l'ēstī`rēn), widely used plastic plastic, any organic material with the ability to flow into a desired shape when heat and pressure are applied to it and to retain the shape when they are withdrawn. Polystyrene is a colorless, transparent thermoplastic that softens slightly above 100°C; (212°F;) and becomes a viscous liquid at around 185°C; (365°F;). It is resistant to acids, alkalies, oils, and alcohols. It is produced either as a solid or as a foamed plastic marketed under the trade name Styrofoam. Its many uses include electrical and thermal insulation, translucent window panels, storage-battery cases, and toilet articles

Q: Is the sandwich board harmful to the human body?: No harm, just pay attention to fire

Q: The steel roof and the sandwich panel are waterproof: The two are actually the same class of things, sandwich panels only the color plate and insulation layer together, the installation more convenient. And the pressure steel roof need to lay another insulation layer and the roof. For both, the weak links of water are between the plates. In the actual project, the seam of the steel plate roof can be made in many forms, some of the overlapping form of waterproof performance is very good, and the common sandwich board roof shape is relatively simple, so the waterproof performance is also worse.

Q: Color steel sandwich panels how much consumption: Consumption is mainly based on the need to build the room size to calculate, the general consumption of 2% to 5%
