The door frame of the stainless steel floor spring door is made of 304 stainless steel thick plate (1.5mm), which is impact-resistant and wear-resistant, and is suitable for high-frequency use scenarios such as shopping malls and supermarkets. The floor spring is a commercial-grade heavy-duty model that can withstand a door leaf weight of 80kg and will not deform after long-term use.

Anti-collision strips can be added to the door leaf to reduce collision damage; it is equipped with a hidden door closer that works in conjunction with the floor spring to ensure a tight closing; double doors can be customized (door opening width 1.2-2.0m) to improve traffic efficiency.
