Advanced and Imported Hard Metal Fast Door

Hard speed door structure:made of the aluminum slat, soft joint rubber strip, load-bearing hinge, guide wheel and so on several parts:

◪The thickness of aluminum insulating door plate is not less than 40mm, the thickness of inner and outer aluminum plate is 0.8mm. the surface is anodized with organic coloring, and the inside is filled with polyurethane (excluding CFC) industrial insulation material, the density is 45kg/m.
◪After jointing aluminum door shutter by soft bonding EPDM strip, the folding life of soft joint part is more than one million times.
◪The design of hinge bearing mode makes the joint of the door curtain not to be forced, the door shutter is not changed, and the flatness can be maintained after a long period of time.
◪When the door is running, it slips in the aluminum track through the guide wheel of polyurethane material, and no friction or noise will occur during the most high speed operation.
◪ The door plate is sealed with ternary ethylene-propylene cold resistant rubber strip, which can effectively insulate temperature and reduce energy loss. It has good sealing, temperature preservation and sound insulation. At least K < 1.7W/ (M2.K) when the door is closed.
