2, purchase of steel doors and windows

The use of low-cost steel doors and windows profiles, calcium carbonate content of more than 50%, additives containing lead salts, poor stability, and affect human health. The inner lining steel is a hot bar plate, the thickness is not enough, some even do not have inner lining steel, glass, hardware also have bad products. The service life is only two or three years.
2) Pay attention to surface quality. The color of plastic profiles on the surface of doors and windows is blue-white or ivory white, clean, smooth and smooth. There are no scratches or bumps on the large surface, and there is no welding or fracture at the welding joint. The surface of the good quality steel doors and windows should have a protective film, and the user should tear off the protective film before use.
3) Pay attention to glass and hardware. The glass should be smooth and dry. The glass and plastic profiles are not in direct contact and there is a sealing bead that closes the gap. The hardware is complete, the position is correct, the installation is firm, and the use is flexible.
4) The sealing strip should be flat, without curling, no groove removal, and no odor. When the doors and windows are closed, there is no gap between the fan and the frame.
5) All four doors and windows are integrated and screwless.
6) Sliding doors and windows open and slide freely, the sound is soft and there is no dust shedding.
7) Special steel linings are embedded in the window frames and fan profiles.
8) The glass should be flat and securely installed. The installed glass does not directly contact the profile. Glass glue cannot be used.
9) If it is a double glass flat layer, there should be no dust and moisture in the interlayer.
10) The switch parts are closed tightly and the switch is flexible.

2) The structure should be reasonable. The anti-theft door with the door frame is more secure and easy to install in the summer. The distance between the gate fence steel pipe is not more than 6 cm (the best hand does not come in).
3) The lock must use the anti-theft lock that locks the third tongue lock with multiple insurance functions. It can be opened or locked indoors and outdoors, and the door lock can be used to protect the iron plate, making it difficult for the keyless person to shake.
