In the metal curtain wall decoration materials, aluminum veneer occupies the main market share, followed by color steel plate, stainless steel plate, etc. These curtain wall materials have their own characteristics, which can perfectly replace the traditional ceramic tile, silicon calcium plate curtain wall, aluminum plastic plate and other curtain walls. Because the curtain wall made of metal plate has the characteristics of fire prevention, rust prevention, changeable shape, and considerable recycling value, which can save a lot of cost for the later decoration and replacement. However, customers often ask if we are the manufacturer of color steel plate. It can be seen that many architectural decoration companies and owners lack systematic understanding of aluminum veneer and color steel plate.
What is color steel plate?
Color steel plate can be divided into two types:
The first one is the curtain wall panel directly sold after antirust and color roller coating treatment of galvanized steel plate. In some places, it is also called color coated plate. Only the conventional 1220 * 2440 mm colored plate is available. The disadvantage is that it can not be customized modeling, color customization can not be carried out according to customer requirements, and the general decoration company will cut and install on site after purchasing.
The second one is that our curtain wall manufacturers purchase galvanized steel plate, after sheet metal modeling processing, and surface paint treatment, we can customize the size modeling, bending, punching and carving according to the customer's engineering drawings, or color matching according to the international color card, which is the same as the aluminum veneer structure. The difference is the difference between aluminum and steel.
What is aluminum veneer?
Aluminum veneer is actually the same as the second process of color steel plate mentioned above, but it has more advantages. Firstly, aluminum plate is lighter than steel plate. The weight of 1 mm aluminum plate is 2.73 kg, and that of 1 mm steel plate is 7.86 kg per square meter. Therefore, the bearing capacity of the wall structure is greatly reduced, which means that if aluminum veneer is used, the cost of auxiliary materials such as curtain wall steel structure can be reduced, and the corresponding safety can also be achieved Greatly improved.
Price of aluminum veneer and color steel plate:
When it comes to the price of two kinds of materials, I believe most customers are easy to get into a misunderstanding. They think that color steel sheet should be much cheaper than aluminum veneer. In fact, there is nothing wrong with the tonnage price of these two metals. However, we often overlook an important problem, that is, steel plate is nearly three times heavier than aluminum plate,
For example: two kinds of materials with thickness of 2mm,
Aluminum plate: 16 yuan / kg, 2 * 2.73 * 16 = 87.36 yuan (excluding processing fee and baking fee)
Hot dip galvanized steel sheet 5 yuan, 2 * 7.86 * 5 = 78.6 yuan (excluding processing fee and baking fee)
The price difference of raw materials is 87.39-78.6 = 8.76 yuan
And because the steel plate is too heavy, higher density, so the processing costs, baking costs, steel frame auxiliary materials costs, will be appropriately increased! As a result, color steel plate is more expensive than aluminum veneer, because of oxidation reaction, the corresponding steel plate can not be preserved for a long time, which is one of the reasons why manufacturers use aluminum plate as metal curtain wall material.
