In the field of architectural decoration, the choice of wall panel materials directly affects the aesthetics, durability and functionality of the space. In recent years, coated steel plates have gradually become the “star material” for public buildings, commercial spaces and even high-end residential wall panel decoration due to their unique performance advantages. This article will analyze the reasons why they are so popular from multiple dimensions such as performance, design, and economy.
1. Physical properties: the core advantage in dealing with complex environments
1. Corrosion resistance and weather resistance
The coated steel plate uses galvanized steel plate or aluminum-zinc alloy plate as the substrate, and the surface is covered with a polymer film (such as PVC, PET) to form a double protective layer. The substrate itself has anti-rust ability, and the coating layer can isolate water vapor, acid and alkali substances and ultraviolet erosion. For example, in coastal high-humidity areas or clean spaces in hospitals, its service life can reach more than 15 years, far exceeding ordinary paint or wood panels.
2. High strength and impact resistance
The steel substrate gives the laminated board high compressive resistance (tensile strength can reach more than 300MPa), which can effectively resist external force collision. It is especially suitable for scenes with dense traffic such as shopping malls and subway stations to reduce the risk of wall damage.
3. Fire prevention and environmental protection
High-quality laminated steel plates can reach B1 fire protection standards, are non-flammable when exposed to fire, and do not release toxic gases. At the same time, its production process adopts environmentally friendly technology, and the recyclability of some products is more than 90%, which is in line with the development trend of green buildings.
2. Design expression: breaking the limitations of traditional decorative materials
1. Infinite possibilities of color and texture
Laminating technology can accurately reproduce wood grain, stone grain, metal brushing and other effects, and provide thousands of customized color options. For example, an international brand exhibition hall uses imitation copper rust texture laminated steel plates to create an industrial retro style, breaking the inherent impression of the cold and hard metal materials.
2. Three-dimensional shape and light and thin characteristics
The coated steel plate can be processed into punching, bending, special-shaped splicing and other forms, with a thickness of only 0.5-1.2mm, which greatly saves space. For example, an art gallery uses a wavy coated steel plate wall, which not only achieves a dynamic visual effect, but also avoids the heavy feeling of traditional stone.
III. Construction and maintenance: a balance between efficiency and cost
1. Modular installation, shortening the construction period by 50%
The coated steel plate is often installed by snap-on or dry hanging, without on-site painting or complicated processing. Taking an office building project as an example, it only takes 5 days to complete the installation of 2000㎡ wall, saving 60% of labor costs compared with traditional tile paving.
2. Maintenance-free and easy to clean
The surface coating layer has anti-fouling properties, and it can be cleaned by wiping with water on a daily basis. Compared with the 3-5 years of renovation cycle of latex paint wall, the maintenance cost of the coated steel plate is almost zero.
4. Economic analysis: better cost in the whole life cycle
Although the unit price of coated steel plate (about 80-200 yuan/㎡) is higher than that of latex paint or ordinary gypsum board, its comprehensive cost advantage is significant:
Durability: The service life is up to 20-30 years, which is more than 3 times that of traditional materials.
Energy saving: Some products add insulation layer to reduce building energy consumption.
Renovation cost: Directly replace a single panel to avoid overall demolition waste.
