To meet these requirements, the quality of steel doors is very good

　　Many people do not know from which aspects to look at the quality of steel doors when they choose them. In fact, as long as the following points are met, the quality of steel doors is very good.

　　1. Opening problem: the door frame and door leaf cannot be closed normally after installation, and the door frame at the top of the door leaf hinge is common. Preliminary cause analysis is door leaf welding

　　The hinge welding is too large, the hinge bulges, and the door leaf edge bulges, resulting in the door leaf can not be closed normally. Field problem The hinge of door frame and door leaf needs to be sanded from the new welding

　　Etc.

　　2. Hinge washer: the hinge has no washer, and the friction between opening and closing of the door leaf is too large; In subsequent production, the washer must be worn.

　　3. Side of the door leaf: one side of the door leaf hinge is bulging, because both sides are squeezed during the pressing process of the door leaf; Eliminate problems in subsequent production

　　Question.

　　4. Door leaf cracking: there are too few welding points on the door leaf panel buckle, and the hinge door leaf panel cracking will increase the welding points in subsequent production, and the welding will be firm

　　Connect.

　　5. Hidden danger of hinge welding: the previous batches of hinge welded door leaves are directly welded on the door leaf sheet. Under the gravity of natural opening, the hinge welded door leaf is directly welded on the door leaf sheet.

　　The side of the door leaf will open, and the hinge on the top of the door leaf will pull the door leaf to deform, causing the subsequent door leaf to fail to close normally.

　　6. False welding of hinge: the hinge splice on the door frame and door leaf has false welding, and the hinge falls off and cracks after being used for a period of time.

　　7. Door frame mounting block: the door frame mounting block with lace is not bent, and is directly welded on the door frame, which cannot be installed normally, and the site installation stops.

　　Sand needs to be removed from new welding and paint.

　　8. The door leaf is too long: after the installation of some door leaves on the site, the lower part has been rubbed to the ground; The problem door leaf cannot be reworked and needs to be disassembled and replaced seriously.

　　9. The position deviation between the door frame mounting block and the door frame mounting hole is more than 2cm, and the door frame is twisted and cannot be installed.

　　10. Other problems: The gap between the door frame and the door leaf is different in size. Some door leaves are too wide to close.
