Do Yiwu make many stainless steel doors and windows?

Whether a stainless steel door and window company is reliable depends not only on the service price, but also on many factors such as service effect, service professionalism and service efficiency. It is suggested that we can find more companies to compare.

Buying stainless steel doors and windows depends on the following points:

1, quality requirements

The thickness of the steel plate of the qualified security door frame should be 0. 15cm, and the thickness of the door body is generally 0.4cm Check the weight of the door, which should be above 40kg. Remove the cat's eye, doorbell box or lock handle to check the internal structure of the door body. The thickness of the steel plate of the door body should have several reinforced steel skeletons, so that the front and rear panels of the door body can be organically connected together to enhance the overall strength of the door body. Generally, the door is filled with polyurethane or honeycomb paper, which plays the role of heat preservation and sound insulation. Among them, the fire door should be filled with asbestos and other materials with fire prevention function, and knocking on the door by hand will make a "bang" sound. Consumers should be flexible in opening and closing doors manually, and the production of fire doors should have the qualification certificate issued by the state.

2. Process quality

Pay special attention to check whether there are welding defects such as open welding, incomplete welding and missing welding. See whether the door leaf and door frame are closely matched, whether the gap is uniform, whether the opening is flexible and whether the joints are tight. The surface of the door panel should be treated with anti-corrosion, and generally it should be painted and sprayed with plastic. The surface of the paint layer should be free of bubbles and uniform in color. Most doors are also embedded with rubber sealing strips on the door frames, so there will be no harsh metal collision when closing the door.

3. Lock check

Qualified anti-theft doors generally adopt special anti-theft locks that have passed the inspection by the public security department, and at the same time, 0.3cm thick steel plates should be placed at the lock mouth for protection. At present, many special anti-theft locks are multi-directional locks. Their advantages are that not only the door lock is locked, but also the upper and lower cross bars can be inserted and locked to fix the door, which greatly improves the prying resistance of the door.

4. Brand guarantee

Brand is a symbol of product quality and service. Brand mainly refers to product brand and dealer brand. When buying security doors in the market, it is best to buy them in a regular large-scale home building materials city. Attention should also be paid to the "FAM" logo, enterprise name, implementation standards and other contents of the security door when purchasing, so that the door that meets the standards can be both safe and reliable.
