The industrial lift door is composed of a series of door panels and runs up along the track. The torsion spring system or the counterweight system is used to ensure the balance of the door body. Different rail systems and lifting methods are designed according to different buildings, which greatly releases the door opening space.
The metal-faced rigid polyurethane sandwich panel (hook panel) produced by Changzhou Yanghu Refrigeration is made of double-sided 0.4mm color steel, with flame-retardant insulation board (with a protective film), and has good thermal insulation performance. The hook plate is made by hand, the metal panel is formed into the mold, and the inner is formed by the injection of polyurethane (PU) sandwich material. The traditional eccentric hook pin is used, and the connection is locked with a hexagonal wrench. Each board hook is connected, whether it is used as a wall board or a ceiling board, it has good strength. Product advantages: 1. Rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is 35～40kg/m3, the thermal conductivity
