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 customers 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+ZZinc 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:Color steel plate, color steel sandwich panels, clean color steel plate is the same thing?
Color plate is veneer 0.4 mm about 23 yuan sandwich panel is a double color plate in the middle plus benzene plate on the 0.3 0.2 is about 45 yuan purification board is used in pharmaceutical plants, food purification plant hanging shed wall panels clean plate surface smooth The price is also expensive and more critical is what you want to do
Q:Color steel sandwich panel can do the widest, can be more than rice
The effective width of the color steel sandwich panel is based on the shape of the steel plate you choose. The surface of the sandwich panel has a flat plate and a few peaks, such as: 1) The surface is flat so that its effective width can reach 1.16 m The maximum width of the steel plate is 1.2 m due to the sandwich panel edge structure in order to increase the compressive strength to be folded 2 cm) 2) the surface is a wave shape of the steel plate that you should choose the peak size and size to calculate its maximum effective width.
Q:How to use the sandwich board to the concrete square column into a cylindrical and finishes are made of aluminum-plastic package
With a sandwich made of a semi-circular in the bottom of the column, the top and the middle of every 500 or so, with expansion bolts wooden side of the board will be fixed on the column, with a sandwich panel saw a narrow wood, Into a round wooden column of the pillars, and then stick to the aluminum plate.
Q:What is the difference between a simple room sandwich panel and a steel plate?
Sandwich panels are two color steel plate sandwich material, usually folder foam or rock wool, insulation, insulation, sound insulation effect.
Q:Polyurethane sandwich board how much money and manufacturers of the situation
According to the production method points: continuous plate and non-continuous plate. According to the panel material points: Caigang sandwich panels and cement sandwich panels According to the use of points: cold storage board and wall panels (cold storage board is generally non-continuous plate, the outer wall is generally continuous plate)   In addition, according to the thickness of polyurethane foam, flame retardant grade and panel thickness, the price range.   Generally calculate the price per square meter.
Q:Is polystyrene sandwich board flammable?
Conventional flat polystyrene polystyrene sandwich panels are non-flame retardant, there is a Hongxin source flame retardant polystyrene sandwich panels, but relatively less flame retardant effect such as rock wool and other core material sandwich panels , And now fire requirements are not allowed to use polystyrene sandwich panels
Q:Rock wool sandwich panels up and down the interface how waterproof
With a butyl water seal tape placed in the overlapping position.
Q:Is there any profit in the rock wool sandwich panels?
Now the fire board profits should be about 20%.
Q:What are the quality standards for color steel sandwich panels?
Reference to national standards: GBT_23932-2009_ Building metal surface insulation sandwich panels
Q:Steel structure plant color steel sandwich panel roof design fire resistance 0.5H, need to apply fire retardant paint
Steel structure color steel sandwich panel fire for 0.5 hours, if it is required to color steel fire board is 0.5 hours, then you must do fire paint, choose a thin fire paint more cost-effective, cheap. If it is required to color steel plate in the sandwich material to 0.5 hours, then you choose the appropriate sandwich material, such as rock wool made of sandwich materials.
