Steel doors are favored and favored by more and more consumers because of their high quality and low price, but how to choose high quality products in the dazzling steel doors?
First of all, the steel-wood suite interior doors are defined as follows: the outside of the door leaf adopts steel plate shaping, the inside is a wooden keel, the door covers are made of multi-layer plates, 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. But now the steel doors on the market are uneven, some manufacturers' products shoddy consumers, disrupting the market order of steel doors. Therefore, when selecting this type of product, the following points should be noted:
Door surface treatment process
Currently, the surface treatment process on the market is mainly divided into two categories: 1. Foil process: The surface of the steel plate is embossed with wood-like PVC material (ie, plasticized). The production process is PVC material that is heat-sealed on the steel plate. Such products are used. During the process, degumming, layering, and leg color may occur due to changes in heat and heat, and the phenomenon of degumming and rusting after the sharps are scratched on the surface is severe. 2. Transfer paint process: steel plate is treated with a phosphating solution → The bottom of the steel plate is sprayed → baked → the wood grain is heat transferred to the bottom of the steel plate and the paint is baked → the surface is painted by car. The performance is relatively stable.
Door material
The door covering materials currently on the market are mainly divided into four categories:
1. Laminate veneer door cover: Multi-layer film (PVC) or sticker paint, etc., due to the surface using a bonding process, in the wet and dry environment, the veneer and the plate easily fall off, delamination, appearance surface layer Foaming phenomenon, uneven. The long-term use of anaerobic bacteria between the veneer and the plate will cause deformation of the material, affecting its use and aesthetics.
2, MDF door cover: The main use of MDF surface stickers do paint or PVC film production, because the density board is made of straw fiber plus glue, made of high pressure, it will expand after water swelling, mildew, deformation, after expansion Its density is greatly reduced, thus affecting the nail holding power and the service life.
3, steel door cover: the use of steel door frame manufacturing process, door and door leaf color-free, set by the steel plate, the surface of the transfer paint process. Most of these types of door covers are single-faced and relatively single-lined, and the installation method is the same as that of steel doors, which makes them lose the essence of steel-wood suite interior doors.
4, multi-layer UV paint veneer door cover: is a new type of door cover, multilayer wood grain transfer printing, surface UV paint finishes technology, product color full, bright, due to the use of UV paint finish so that the product To achieve the best state of use, with no deformation, no cracking, moisture, heat, wear, no pollution and so on.
Line material
The lines on the market are mainly divided into three categories: 1. WPC lines: wood-plastic substrate surface film (PVC) or sticker paint, due to the surface using a bonding process, between the veneer and the substrate during use Falling off, prone to surface blistering, wood-plastic substrate easy to powder and other phenomena; 2, steel line: plastic steel substrate surface film (PVC), due to the surface of the paste process, in the use of the process of veneer and substrate Between the easy fall off, surface blistering and other phenomena; 3, plastic paint lines: the use of wood grain and UV paint finishes on the surface of high quality steel substrate, product color full, bright, so that the product reaches the best state.
Steel plate thickness
The thickness of the steel plate is the part that can best reflect the product quality. Due to the diversification of market prices, the thickness of the steel plate is also different. If the surface of the product is to be smooth, smooth and stable, the thickness of the steel plate should be 0.5 mm or more and 0.5 mm or more. Impact and impact resistance can achieve good results. For inferior products of some companies, 0.3mm or thinner steel sheets are used, resulting in poor surface smoothness and insufficient door steel rigidity. Such products severely disturbed the normal competition order of the steel and wood door industry, damaged the interests of consumers, and brought more quality complaints and after-sales problems to distributors of steel and wooden doors. It is suggested that the market should firmly resist such inferior products.
Consumer reminder: When purchasing steel wood suite interior doors, we can comprehensively consider the above points and consider the product's price/performance ratio. Under selected selection, select high-quality products to avoid damage from consumer rights.
