Some minor problems with roof slabs are in our solutions and handling. Today, China PPGI corrugated roofing sheet manufacturer has listed two more detailed issues - the waterproofing of the roof through the roof and the sealing of the double-sided roof.

Waterproof treatment of the rod wearing the roof
1. According to the different positions of the rods wearing the roof, according to the drainage conditions, different cutting methods are adopted respectively. There are two types of slitting and crosscutting.
2. The treatment method is mainly to add water retaining ring and waterproof with multi-channel polyurethane waterproof coating.
3. A single water-passing rod member is provided with a water retaining ring separately; a rod member that passes through the plate is arranged, and a series of water retaining rings are arranged along the longitudinal slit.

Double-layer roof sealing method
The skeleton of the double-layer roof block, that is, the curve, is a combination of several more complicated curves. China PPGI corrugated roofing sheet manufacturer reminds you that it affects the tightness of the seal installation and whether the roof shape can reflect the architectural design requirements. The solution to this is:
1. Accurate calculation of the wing sample for the rubbing, supplementing several simple parts that can be adapted to various angles and position adjustments.
2. When installing, use the baseline reference line to adjust the deflection change caused by the deformation of the steel structure.
3. The sealing baffle itself is assembled with narrow strips to accommodate the shape of the non-expandable curved surface.
Paying more attention to the above two problems in detail can reduce many problems caused by improper handling. PPGI corrugated roofing sheet manufacturer can take care of these problems during installation, which can make consumers trust manufacturers and choose more products.
