Steel doors because of its inexpensive by more and more consumers of the favor and favorable, but how to choose in the dazzling steel doors to the quality of the Italian products? First of all, the steel and wood suit is defined as: the external use of steel plate stereotypes, the internal wood keel, the door with multi-layer board, the door line with plastic or wood plastic, so that the product has no deformation, no cracking, Long life and other advantages. But now the steel doors on the market uneven, and some manufacturers of products shoddy consumers, disrupt the steel door market order. Therefore, in the choice of such products, should note the following:
Door leaf surface treatment process
The surface treatment process is divided into two categories: 1, foil process: the surface of the steel sheet affixed to the grain of PVC material (ie, plastic), the production process for the PVC material by heat sealing paste in the steel, such products in use The process, due to changes in hot and cold, there may be degumming, from the layer, leg color and other phenomena, and sharp scratches the surface after degumming and corrosion more serious; 2, transfer paint process: steel phosphating solution → The bottom of the steel plate spray treatment → baking → the wood will be heated to the bottom of the steel paint on the paint → baking → surface using automotive paint process. Performance is relatively stable. In the case of
The door of the door materials are divided into four categories:
1, multi-layer board veneer door cover: multi-layer board foil (PVC) or stickers paint, etc., because of its surface using the bonding process, in a wet and dry environment between the veneer and the plate easily fall off, delamination, Bubble phenomenon, not flat. Long-term use of veneer and plate will produce anaerobic bacteria, the material deformation, affecting the use and appearance.
2, MDF door cover: the main use of MDF surface stickers do paint or paste PVC film production, because the density board is straw fiber with glue, made by high pressure, it will be in the water after swelling, mold, deformation, after expansion Its density greatly reduced, thus affecting the nail force and service life.
3, steel door sets: the use of a steel door frame of the production process, the door and the door without color, formed by the steel plate, the surface using transfer paint process. Most of these doors for the single-sided lines and a single line, the installation method and the same steel doors, so that it lost the essence of steel doors and windows interior doors.
4, multi-layer board UV paint trim door cover: is a new type of door sets, multi-layer board using transfer wood, surface UV paint finishes, full color products, bright, due to the use of UV lacquer finish so that products To achieve the best use of the state, with no deformation, no cracking, moisture, heat, wear, no pollution and so on. In the case of
The lines on the market are divided into three categories: 1, wood-plastic lines: wood-plastic substrate surface foil (PVC) or stickers paint, because of its surface using the bonding process, in the process of use between the veneer and the substrate 2, plastic steel lines: plastic substrate surface film (PVC), because of its surface using the bonding process, in the course of the use of veneer and the substrate 3, plastic steel paint lines: in the high-quality plastic substrate surface using transfer wood and UV paint finishes, products full color, bright, so that the product to achieve the best condition.
Thickness of steel plate
Steel plate thickness is the best part of the product quality, due to the diversification of market prices, steel plate thickness is also different, such as to achieve product surface smooth, smooth, stable performance, steel plate thickness should reach 0.5mm and 0.5mm above, its prevention Hit, impact resistance in order to achieve good results. And some enterprises of inferior products, the choice of 0.3mm or thinner steel plate, resulting in poor surface roughness, the door of the lack of steel. This product seriously disrupted the steel doors of the industry's normal competitive order, damage the interests of consumers, to the steel doors of the dealers also bring more quality complaints and after-sales problems, the proposed market firmly resist this inferior products.
