Steel-wood doors have been favored and popular by more and more consumers because of their high quality and low price. But how to choose high-quality and desirable products in the dazzling steel-wood doors?
First of all, the steel-wood suit is defined as follows: the exterior of the door leaf is shaped by steel plate, the interior is wooden keel, the door cover is made of multi-layer board, and the door line is made of plastic steel or wood plastic, so that the product has no deformation, no cracking, no pollution, Long life and other advantages. However, the steel doors and doors on the market are now uneven. Some manufacturers' products are used to deceive consumers and disrupt the order of the steel door market. Therefore, when choosing this type of product, you should pay attention to the following points:
Door leaf surface treatment process
The surface treatment processes on the market are mainly divided into two categories: 1. Filming process: PVC material with imitation wood grain on the surface of the steel plate (ie, plastic molding), the production process is that the PVC material is heat-bonded to the steel plate, and such products are used. In the process, due to changes in heat and cold, degumming, delamination, leg color, etc. may occur, and the phenomenon of degumming and rusting after sharp scratching of the surface is serious; 2. Transfer baking varnishing process: anti-corrosion treatment of galvanized steel plate → The bottom surface of the steel plate is sprayed and processed → baked → the wood grain is heated and transferred to the paint on the bottom surface of the steel plate → baking → the surface is painted by automobile. The performance is relatively stable.
Door cover material
The door cover materials on the market are mainly divided into four categories:
1. Multi-layer veneer door cover: multi-layer board film (PVC) or sticker paint, etc. Due to the surface bonding process, the veneer and the plate are easy to fall off, delaminate, and surface layer appear in a humid and dry environment. Foaming, uneven. Long-term use of anaerobic bacteria between the veneer and the plate will cause deformation of the material, affecting the use and aesthetics.
2. MDF door cover: It is mainly made of MDF surface sticker for painting or PVC film. Because MDF is made of straw fiber and glue, it is formed by high pressure, so it will expand, mold and deform after water absorption. Its density is greatly reduced, which affects the nailing force and service life.
3, steel door cover: the production process of steel door frame is adopted, the door cover and the door leaf have no color difference, the steel plate is shaped, and the surface adopts transfer paint process. Most of these door covers are single-sided lines and have a single line. The installation method is the same as that of the steel door, which makes it lose the essence of the interior door of the steel-wood set.
4, multi-layer board UV paint veneer cover: is a new type of door cover, multi-layer board using transfer wood grain, surface UV paint finish technology, product color is full, gorgeous, because of the use of UV paint finish It achieves the best condition of use and has the characteristics of no deformation, no cracking, moisture, heat, abrasion and pollution.
Line material
The lines on the market are mainly divided into three categories: 1. Wood-plastic lines: wood-plastic substrate surface film (PVC) or sticker paint. Due to the surface bonding process, it is easy to use between the veneer and the substrate during use. Shedding, prone to surface foaming, wood plastic substrate easy to powder and other phenomena; 2, plastic steel line: plastic steel substrate surface film (PVC), due to its surface using a bonding process, veneer and substrate during use It is easy to fall off and foaming on the surface layer; 3. Plastic steel paint line: The surface of high-quality plastic steel substrate adopts transfer wood grain and UV paint finish technology, the product color is full and gorgeous, so that the product reaches the best state.
Steel plate thickness
The thickness of the steel plate is the part that best reflects the quality of the product. Due to the diversification of market prices, the thickness of the steel plate is also different. If the surface of the product is flat, smooth and stable, the thickness of the steel plate should be 0.5mm and 0.5mm or more. Collision and impact resistance can achieve good results. The inferior products of some enterprises use 0.3mm or thinner steel plates, resulting in poor surface flatness and insufficient steel rigidity of the door. Such products have seriously disrupted the normal competition order of the steel-wood door industry, damaged the interests of consumers, and brought more quality complaints and after-sales problems to the dealers of steel-wood doors. It is recommended that the market resolutely resist such inferior products.
