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.
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.
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.
Our gutter boards are constructed using premium materials, specifically Sodium silicate combined with Nano calcium, or ASA PVC, offering excellent durability and resistance.
Depending on the specific installation environment and material choice, the service life of the gutter boards ranges from 20 years up to 50 years.
The gutter boards feature an effective length of 800mm and are available in thickness options ranging from 2.0mm to 3.0mm.
Maintaining a drainage slope of 0.5% to 1% ensures that rainwater flows smoothly toward the drain outlet without pooling on the board.
To prevent displacement and leakage, the connection to the roof structure must be firm. This is typically achieved using welding, bolt connections, or rivet connections.
It is essential to seal the junction between the gutter board and the roof, as well as the connections between the boards and the drain outlet, using waterproof membranes and high-quality sealants.
