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: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:Color steel sandwich panels are prefabricated or on-site production processing
Not prefabricated, is custom production.
Q:Fire protection recommendations for color steel sandwich panels
Color plate can fire from six aspects: First, the use of good fire performance rock wool as a core material, which is a permanent solution. Second, in the process of building, the core material to stay away from welding, gas welding and other fire operations; Third, in the course of the use of some heat, the fire should not be next to the steel plate, to maintain a certain distance. If you want to set the kitchen in the color steel room, you need to have insulation layer, the wall should be installed fireproof rock insulation layer; Fourth, the wire, the cable is best not to pass from the core material, if necessary to wear protective cover Tube, socket, switch box should be used metal galvanized box and the use of mounted method; Fifth, indoor and outdoor with a simple fire fighting equipment, conditional installation of fire alarm should be convenient to facilitate the rapid evacuation of personnel; At least 6 meters to maintain a safe distance. Insulating materials that are not strictly flame-retardant are not flammable but are self-igniting. Strict, scientific and effective management, so that the fire away from the flammable color steel plate sandwich filler material, is to prevent color steel room fire is one of the important ways.
Q:Blockboard (sandwich panel) decoration cabinet right?
The cabinet can be used with blockboard, blockboard grip screw force, high strength, with quality Kennedy, sound absorption, insulation and other characteristics, and moisture content is not high, between 10% -13%, easy processing, the most use widely. Blockboard than solid wood sheet stability, but fear of wet, construction should be avoided to avoid the kitchen. Uses: furniture, doors and windows and sets, partition, false walls, heating hood, curtains and so on.
Q:Does the country 's steel market have sandwich panels?
Sandwich panel products are composed of two layers of metal panels (or other material panels) and directly in the middle of the panel foam, mature molding of the composition of the polymer core insulation. These sandwich panels are easy to install, lightweight and efficient. Filling system is also used to close the molecular structure, you can put an end to the condensation of water vapor. The forming of the outer steel sheet takes into account the structural and strength requirements, and takes into account the appearance, the inner layer is formed into a flat plate to suit various needs. Guoqiang steel market with sandwich panels.
Q:What is the thickness of the upper and lower panels of the rock wool sandwich panel?
1. Upper / lower steel plate thickness: 0.25 ~ 0.8mm color steel / electric, hot galvanized sheet / stainless steel plate 2. Core material: (mine) rock wool capacity of 120 ~ 150kg / m 3. Side seal steel strip or no side seal steel strip: 0.4mm ~ 0.8mm galvanized sheet 【Product Specifications】 1. Effective width of the mouth: 950mm, 1150mm; thickness of 40mm ~ 150mm; length is not limited 2. Board protection form: complex PVC protective film 【Product Features】 1. Advantages: good fire resistance, sound insulation better. 2. Disadvantages: strength is not good enough. 3. Fire rating: Class A
Q:Are you using a polystyrene sandwich panel or a rock wool sandwich panel?
Mainly to see the use of activities, fire or rock wool sandwich board is good
Q:Sandwich panel prices, and specifications
Y-2100 intelligent polystyrene sandwich board vertical production line, is our company according to the relevant requirements of the market for the bold design of their own innovative manufacturing in line with the "building partition with light strip" JG / T169-2005 standard production line self Equipment, size and cross-section size, product specifications in line with national recommended series. The production line will be divided into the storage process system, polystyrene particle grammar system, automatic feeding system, sandwich material mixing system, forming plate machine, casting system, mold recycling system, a product casting molding, the production of calcium silicate cement fiber pressure Plate pallet heart panel. A board machine production line can achieve the class output 600-800 square meters of finished products, automatic control of the production process, each production line required artificial 4-6 people.
Q:Color steel plate wall how many meters a general support, corrugated color plate non-sandwich panels
Is there any angle between the top and bottom of the color plate? If not, the two panels at the junction should be set up a support point. If there is, 2-3 sets of color board can be set up to support, depending on the size of the project area average annual wind. We usually set up a 2 support.
Q:Sided 0.8 thick stainless steel plate extruded board sandwich panels there are production
Good insulation or polyurethane
