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: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:Color steel sandwich panel wall, you can directly spray really stone paint what is the practice
According to the following construction methods to achieve good results: 1, in the sandwich panel (plate) on the gap to be caulking. It is recommended to use the home of the heart of the card to worry about toughness to fill the joints, and then paste the seam (master understand). 2, if directly in the sandwich panel (plate) on the batch of putty powder or spray paint really easy to drop off the phenomenon of paint, the first primer, it is recommended to use the home of the board of people worry-free putty scraping again There are), to be dry and then approved scraping putty powder. 3, spray really stone paint.
Q:Color plate and color steel sandwich panel difference
Color steel plate galvanized coated iron plate, the use of color steel plate is not insulated. Color steel sandwich panels are double-sided steel plate with the center of the core material through the machine continuous pressure from the type. The core material has foam, rock wool, polyurethane and extruded. The main feature is the insulation of insulation. hope this helps
Q:Color steel sandwich board surface rust how to do
The surface rust is because the color plate surface paint off the inside of the steel plate caused by oxidation. General this situation waiting for oxidation rust, perforation. Refurbishment is not impossible, but the cost is high. You can try to wash the rust with acid, Brush paint.
Q:Rock wool sandwich board Yanmian generally what brand, quality Zeyang?
Rock wool sandwich panels in the rock wool are generally divided by the region, the quality can be, this has a national test report on it, the quality of the country by the check, OKorder Wang Teng Steel Co., Ltd. Yanmian sandwich Board quality is good, the price is reasonable, you are welcome to come to order!
Q:50mm thick roof color steel sandwich board price is generally how much money a m2?
One meter 38
Q:The foam sandwich panels of the insulated chicken coop are burned! How to do hollowing out?
Magnesium cement curing to release a high heat, generally in the 1000 ~ 1350J / gMgO, and the heat release rate is very fast, the highest reaction system center temperature up to 150 degrees Celsius. Ordinary Portland cement hydration heat is only 300 ~ 400J / g, can be seen magnesite cement is the ordinary cement hydration heat 3 to 4 times. As can be seen from the above data, especially in the summer high temperature production, must strictly control the magnesite cement curing process. At present in Hebei Wen'an, Cangzhou area, in order to save production space, usually finished a board, and then according to this board for the operating platform in the above do 3 to 5, we all know, thermal conductivity of foam material is poor, and Ling Magnesium cement curing is a fast high heat process, so the production often encountered due to exotherm is too high and burned foam board situation, that is, "burn board" "hollowing" phenomenon.
Q:Is the sandwich panel toxic?
Sandwich panels are environmentally friendly materials, how many are a bit, no big problem, you can rest assured that use. But I would like to remind is in the color of the steel house, pay attention to the improper use of the kitchen to prevent fire. For the quality of sandwich panels, the world color steel is good to understand the next.
Q:Color steel sandwich board found how to do leakage?
Color steel sandwich panels: 1. Corrugated sandwich board may be in the fixed when the nail is too tight lead to corrugated subsidence, the formation of small puddles, it will leak, the solution with mildew copper phosphate repair. 2. Flat sandwich plate may be due to the possibility of two plates of the gap between the edge of the gap is not enough height, the general rain is no problem, the rainfall is large, the solution is to increase the height of the edge fold (the cost of repair each gap about 15 yuan about). Also do not understand can ask!
Q:Polyurethane sandwich panel production line
Polyurethane sandwich panel production line that is polyurethane composite insulation board production line, is in the upper and lower layers for the cement cloth, aluminum foil, non-woven Cloth, paper and other soft surface base material, the production of phenolic (polyurethane) foam sandwich panel special equipment, sandwich panel thickness of 20-100mm, width 1200mm, length custom. Products are mainly used for external wall insulation and central air conditioning ducts and so on. Its working principle for the polyurethane liquid by the perfusion metering pump to a certain percentage of mixed into the mixing head after mixing evenly on the bottom of the sandwich panel surface material, and the upper surface material together with the laminating machine, in the laminating machine Chain plate between the foam curing molding; after the molding of the sandwich panels in the production line after trimming on both sides, is automatically track the cutting machine cut into the required length of the product. Polyurethane sandwich panel is made of polyurethane rigid foam as the insulation layer of bimetallic, single metal, non-metallic composite sheet, usually used in industrial plants, logistics warehousing, integrated housing walls, roofing system.
