Made of steel and wood. The bottom of the upper sliding door is equipped with a black rubber hose-shaped sealing strip. Door opener: Youtai solid wood garage door opener, maintenance-free, stable quality. Power is stronger, operation is smoother, noise is lower, and energy is saved by 70%. The lifting force and descending force can be appropriately adjusted according to the actual situation to minimize losses. Door opener function: rebound in case of resistance, remote control distance of 30-50 meters, equipped with two remote controllers and two keys. The guide rail is made of 1.5mm cold-rolled steel plate produced by Baosteel, and its surface is silvered. The roller is made of high-strength wear-resistant multi-nail-cut POM engineering plastic and embedded with ball bearings. Door hinges are made of 1.5 Baosteel cold-rolled steel plate with silver plating on the surface. The steel wire coil is made of high strength aluminum alloy.

First of all, there is a awning, and rainwater can be poured directly on the door; The expansion and contraction of the door panel is not only affected by the natural environment, but also related to the deformation degree of the material itself. Materials with small deformation can be used, and the moisture content of the materials can be well controlled; According to the local natural climate conditions, the wood used to make the door leaves should be dried, and it should regain its moisture for more than a week, giving the material enough curing period to stabilize the water content of the material at around 12%, and then cutting and adding it; In addition, it is necessary to control the moisture content of materials in the production process, and ensure that the material rate does not absorb moisture and the moisture content does not rise from cutting to semi-finished products until painting. This requires that materials should be put into a constant temperature room in time to keep the moisture content of wood from rising; In the manufacturing process, through different knotted falcon structures, anti-deformation adhesive tapes are added at the most important deformation parts of the door structure to minimize the deformation. Will not respond to the appearance and use of the door. Solid wood garage door balancing system: the balancer adopts torsion spring balancing system. The bushing of the balance system adopts galvanized steel pipe. Adding 65 Mn to the torsion spring material increases the fatigue resistance and prolongs the service life by 2-3 times.
