Metal plate: The surface is nano-sprayed with Thai gold treatment, which enhances the scratch resistance and oxidation resistance of the panel; the tensile strength is not less than 220N/mm2, and it does not fade or deform within 50 years.
Aluminum alloy profile: surface polishing, anodized gold sand treatment, the surface of the profile is enhanced by scratch resistance and oxidation resistance, and the tensile strength is not less than 220N/mm2. Does not fade in 50 years without deformation.
1. After assembly in each standard column, the limit deviation of the outer dimensions (length, width, height) is ±1mm.
2. After each standard column is assembled, the gap between the door panel and the box is less than 1mm, and the gap between the side panel and the frame is less than 1mm.
3. The top and the base have a deviation of parallelism of not more than 1 mm/m and a total length of not more than 1 mm; the deviation of parallelism on the same section is not more than 1 mm/m, and the total length is not more than 1 mm.
4, with light products, the surface of the box should not be exposed, a ballast device for every 200 doors, a safety protection device for every thousand doors.
5. The limit deviation of the unfilled tolerance dimension of the part is in accordance with IT13-14 in GB1804.
