1、 Single layer FRP sheet and profiled steel plate overlap
1. Ordinary waveform board overlap: The FRP sheet is directly fastened to the surrounding profiled steel plates, and waterproof tape is applied throughout the overlap with the steel plate side. The end overlap with the FRP sheet in the length direction should be placed on the purlin, and the overlap with the color steel plate should be greater than 250mm. Two 2x20mm waterproof tapes are applied at the overlap end.
2. Corresponding to the overlap of Jiaochi River steel plates: For the Jiaochi concealed buckle type FRP sheet, it is recommended to use a continuous strip daylighting from the ridge to the eaves. If point daylighting is necessary, the FRP sheet or profiled steel plate near the ridge end that overlaps with the FRP sheet should be cut and treated with waterproof edging or other waterproof treatments.

3. Solution 1 for the treatment of pressed steel plates corresponding to 180% 360 ° vertical seam locking edges: After adding edge trimming to the groove type skylight sheet, it can be equivalent to overlapping with the color steel plate. After pasting waterproof tape between the waterproof edge trimming and the skylight sheet, it can be fixed with special waterproof aluminum rivets (note: the method of YX760 as shown in Figure 2 can also be referred to for the Jiaochi 2 version such as HV475).

4. Solution 2 for the treatment of pressed steel plates with 180 ° 360 ° vertical seam locking edges: simple and convenient installation, simple waterproof treatment, and good overall effect. It is suitable for various overlapping methods such as point type and continuous strip.

2、 Double layer FRP sheet overlapping node diagram
1. The double-layer panel treatment plan for the corresponding sandwich insulation steel plate:
a. Schematic diagram of TD760 and Q900 overlapping: Similar to the double-layer FRP sheet overlapping with sandwich steel plate, a Z-shaped bracket needs to be added in the middle of the double-layer FRP sheet for support.

2. The FRP sheet treatment plan corresponding to the high-strength aluminum foil veneer insulation cotton single-layer steel plate insulation roof:
a. Schematic diagram of SS468 double-layer sheet with edge closing and lapping: two layers of FRP sheets with an empty gas layer in the middle of edge closing are used as the thermal insulation layer, and the ports on both sides are sealed with PE foam plugs.

4、 Schematic diagram of FRP sheet wall overlap
a、 The wall FRP sheet is made of ordinary corrugated sheet, which is easy to overlap and waterproof. It can be arranged in various ways according to customer requirements, and the overlapping part in the length direction should not be less than 200mm.

5、 Schematic diagram of arc-shaped overlapping of FRP sheet
Our LS838 FRP sheet has a peak height of 16mm and a small bending radius of up to 2m. It can be widely used in curved roof structures and has higher strength than low peak FRP sheets and flat sheets. It is waterproof, easy to handle, and has a beautiful effect.
