Installation Points
Ensure drainage slope
During installation, it is necessary to ensure that the gutter board has a certain drainage slope, generally 0.5%-1%, so that rainwater can flow smoothly to the drain outlet.
Firm connection
The connection between the gutter boards and the roof structure must be firm to prevent leakage and displacement. Common connection methods include welding, bolt connection, rivet connection, etc.
Do a good job of waterproofing
The junction between the gutter board and the roof, the connection between the boards and the drain outlet, etc., should be waterproofed with waterproof membranes, sealants, etc. to prevent rainwater leakage.
