How to choose steel doors?
Steel-wood doors have been favored and favored 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, the steel-wood suits are defined as follows: the outer part of the door leaf is shaped by steel plate. The interior is a 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 the advantages of no deformation, no cracking, no pollution, long service life and the like. However, the steel-wood doors on the market are uneven, and some manufacturers' products are used to deceive consumers and disrupt the order of the steel-wood 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. Film-coating process: PVC material with imitation wood grain on the surface of steel plate (ie, plastic molding). The process of making PVC material is heat-bonded to the steel plate. During the use of such products, degumming may occur due to changes in heat and cold. , the phenomenon of layering, leg color, etc., and the phenomenon of degumming and rusting after the sharp object scratches the surface.
2, transfer paint process: steel plate anti-corrosion treatment by phosphating solution → steel plate bottom surface spray treatment → baking → transfer wood grain heating to the bottom of the steel plate paint → baking → surface using automotive paint process. The performance is relatively stable.
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 can reach the best condition of use, has the characteristics of no deformation, no cracking, moisture proof, heat prevention, wear resistance, no pollution, etc. More features can be viewed in the Chinese door and window net.
The lines on the market are mainly divided into three categories:
1. Wood-plastic line: wood-plastic substrate surface film (PVC) or sticker paint. Due to the bonding process on the surface, the veneer and the substrate are easy to fall off during use, and the surface layer is foaming and wood-plastic. The substrate is easily powdered and the like.
2, plastic steel line: plastic steel substrate surface film (PVC), due to its surface using a bonding process, in the process of use between the veneer and the substrate easy to fall off, the surface layer foaming.
3, plastic steel paint line: on the surface of high-quality plastic steel substrate using transfer wood grain and UV paint finish technology, product color is full, 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.
