The classification of metal curtain walls can be divided into aluminum composite panels, single-layer aluminum panels, honeycomb aluminum panels, sandwich thermal insulation aluminum panels, stainless steel panels, film-coated steel panels, and enamel steel panels. According to the different surface treatments of the panels, metal curtain walls can be mainly divided into curtain walls such as light panels, matt panels, profiled panels and corrugated panels.
Stainless steel plates include mirror stainless steel plates, matt stainless steel plates, titanium plates, etc. The durability and wearability of stainless steel plates are good, but too thin plates will bulge, and too thick plates have high self-weight and price. Therefore, stainless steel plates are not common in the use of curtain walls, but play a greater role in the local decoration of curtain walls. effect.
Coated steel plate is a decorative steel plate with color film, which has the characteristics of good corrosion resistance, bright color, beautiful appearance, convenient processing and forming, and has the original strength of the steel plate and the price is low. The substrates of coated steel sheets include cold-rolled substrates, hot-dip galvanized substrates, and electro-galvanized substrates. The types of color filters can be divided into single layer and composite. The surface texture is various, and the common ones are wood grain, stone grain, wire drawing, pattern and so on.
Coated steel sheets are used in industries such as building appliances and transportation. For the construction industry, they are mainly used for the roof walls and doors of industrial and commercial buildings such as steel structure workshops, airports, warehouses, and refrigeration. In recent years, the number of color steel sheets used in civil buildings is also gradually rising.
