What are the general specifications for the manufacturing and installation of arched color steel arch roofs?
General Regulations for the Production and Installation of Arched Roofs: The specifications of color-coated steel sheets used in the arched roof structure, including base plate thickness, coating weight, coating requirements, and appearance quality, should comply with design specifications and the provisions of the "Technical Code for Structural Technology of Arched Corrugated Steel Roofing." Reliable waterproof and moisture-proof measures should be adopted for the storage of color-coated steel sheets.
Before the manufacturing and installation of the arch-shaped roof structure unit panels, a construction plan should be determined based on the on-site conditions, and a construction organization design should be compiled.
Color-coated steel plates should be handled using hoisting equipment; forklifts or direct handling with steel cables are not recommended. However, in actual engineering handling processes, steel cables are often used.
During manufacturing and installation, protective measures should be taken to maintain the integrity of the colored coating on the unit panel surface. In case of local scratches or minor coating detachment, the same type of repair paint should be used for修补. The color of the repair paint should match the original colored coating and should cure under field conditions.
When coated steel sheets may come into contact with corrosive substances or are used in other harsh environments, the cut edges of the sheets should be treated for corrosion resistance.
Measurement tools used during construction should be pre-calibrated, and their operation should be standardized and unified. The ruler used for detecting the curvature of arc-shaped unit panels must have sufficient rigidity, and its length should not be less than 2 meters.
The reserved parts for hanging items on the roof should be made of color-coated steel sheets; other materials with poor corrosion resistance should not be used.
