Steel plates exhibit thermal expansion and contraction characteristics. The standing seam roof system utilizes a sliding construction to relieve internal stress caused by thermal expansion and contraction, thereby preventing damage to the connecting structure due to long-term repeated stress.

The eave is fixed, and the roof panel undergoes thermal expansion and contraction relative to the eave. The temperature stress is released through the sliding of the support and the deformation of the ridge cap, ensuring long-term reliable wind resistance and waterproof performance

Selection of sliding bearings

Based on different specifications of fiberglass insulation cotton, three height options of sliding supports are provided for matching use.

When the length of the single slope of the roof exceeds 60 meters, a long support with a sliding displacement of up to 143mm can be selected beyond a range of 60 meters from the fixed point of the cornice.
