Stainless steel floor-elastic doors in shopping malls and office buildings are frequently used equipment, but they often experience "frequent failures": some doors make harsh noises when opening and closing, some doors close quickly and slowly, or even fail to close automatically, which not only affects the user experience, but also poses safety risks. Why is the stainless steel floor pop-up door always stuck?

Corners are cut on core components. Many low-priced floor spring doors use inferior floor springs with a load-bearing capacity of less than 80kg. Kunming shopping mall doors often need to be equipped with glass, and the overall weight exceeds 100kg. Long-term overload use will cause hydraulic oil inside the floor spring to leak and cause switch jams. In order to reduce costs, some manufacturers use 201 stainless steel with a thickness of only 0.8mm for the door frame, which is less resistant to deformation than the standard 1.2mm 304 stainless steel. 60%, the door body is easy to bend when opened and closed for a long time, thereby jamming the track.

The installation workmanship is not up to standard. Some installation teams did not operate according to the specifications: the error in the positioning of the spring line exceeded 5mm, resulting in uneven gaps between the door frame and the door body, causing friction and jamming when opening and closing; only 5cm short expansion tube bolts were used to fix the columns, which were not embedded deep enough into the wall. After long-term use, the columns tilted and the door body could not slide smoothly; some teams even omitted the "floor spring horizontal debugging" step, resulting in uneven force on the floor springs and shortening their service life.

Sealing and protection are not in place. If it is rainy and humid, if the bottom seal of the floor spring door is made of ordinary rubber, it will easily age and harden when exposed to water, and the friction resistance with the ground will increase, causing jamming. If the connection between the door frame and the wall is not waterproofed, rainwater will penetrate into the interior and corrode the floor spring parts, which will also cause mechanical failure. In addition, if the outdoor floor spring door is not equipped with a dust cover, dust will enter the inside of the floor spring, which will wear the piston assembly and aggravate jamming.

Routine maintenance is missing. Most users neglect the regular maintenance of floor spring doors: lack of oil in the floor spring bearings will cause abnormal rotation and stagnation; accumulation of dust and debris in the track will hinder the sliding of the door body; loose door hinge screws that are not tightened will cause the door body to sag and rub against the door frame. Especially in Kunming, spring is very windy, and sand and dust can easily enter the tracks. Failure to clean them in time will accelerate component wear.

Kunming stainless steel floor spring door manufacturers have strict requirements on core components and installation processes: floor springs are imported, such as Doma from Germany and Panasonic from Japan. These floor springs can bear a load of up to 120kg and have a service life of more than 100,000 times, ensuring that the door opens and closes smoothly; the door frame is made of 1.5mm thick 304 stainless steel, which is 30% more resistant to deformation than ordinary 1.2mm thick door frames, which can avoid jamming caused by bending of the door frame after long-term use.
