FAQ
Q：How about the quality of your gutter pipes?
A：The quality of our gutter pipes is excellent, which is mainly reflected in the following aspects:
- Stringent Raw Material Control: For PVC gutter pipes, high - quality polyvinyl chloride raw materials are selected. These materials are anti - aging and have strong toughness, enabling them to withstand complex weather conditions. As for aluminum alloy gutter pipes, high - strength aluminum alloys are carefully chosen, which contain alloying elements such as magnesium and silicon, ensuring good corrosion resistance and mechanical properties.
- Advanced Production Technology: When manufacturing PVC gutter pipes through injection molding, advanced injection molding equipment and techniques are utilized to ensure uniform wall thickness and accurate dimensions of the products. For custom - made aluminum alloy gutter pipes, advanced extrusion and forming technologies are adopted, and the surface is delicately treated to enhance weather resistance.
- Strict Quality Inspection: There are multiple inspection procedures throughout the production process. From the inspection of raw materials upon arrival, random inspections during production to a complete inspection of finished products, all are carried out in accordance with high standards to ensure that each gutter pipe meets high - quality requirements.
Q: What types of PVC gutter pipes do you have?
A: PVC Gutter Pipes
- Classification by size: For gutters, common specifications include 4 - inch, 5 - inch, 5.2 - inch, 7 - inch, 8 - inch, etc. For pipes, there are round pipes with diameters of 2.95 inches, 3.15 inches, 3.94 inches, and rectangular pipes of 60x80mm and 75x100mm.
- Classification by shape: There are square gutters and U - shaped gutters. Square gutters have a simple appearance and look more beautiful when matched with buildings. U - shaped gutters have a higher drainage efficiency and can effectively collect and discharge rainwater.
- Classification by wall thickness: There are products with different wall thicknesses such as regular models and thickened models. The thickened gutters have higher strength and are more durable.
Aluminum Alloy Gutter Pipes
- K - type aluminum alloy gutter pipes: They have an elegant shape, presenting a hyperbolic curve, embodying the modern European and American style. There are various sizes and colors available. Sizes include 5 - inch, 6 - inch, 7 - inch, etc. Pipes come in dimensions of 50x80mm, 60x80mm, 80x100mm, 90x120mm, 120x150mm. Colors include white, black, coffee, gray, etc.
- U - type aluminum alloy gutter pipes: With a semi - circular design, they are natural and primitive, showing the Spanish style. Common sizes are 5.5 - inch, 6 - inch, 7 - inch, etc.
