A Galvanized Gutter is a key component of a building’s rainwater drainage system, primarily responsible for collecting and channeling rainwater from the roof to the downpipes. Typically made from hot-dip galvanized steel, this product combines the structural strength of steel with the exceptional corrosion resistance of a zinc coating. It is valued for its durability, cost-effectiveness, and adaptability, offering a long-service-life solution for efficient water management in various architectural and industrial structures.
Technical Parameters
The following table outlines the typical specifications for hot-dip galvanized steel gutters, which can often be customized to meet project requirements.
| Parameter | Description / Typical Range |
|---|---|
| Base Material / Standard | Common steel grades include DX57D+Z, Q235B, and Q355B, conforming to standards like GB/T 2518-2019. |
| Material Thickness | Ranges from 0.5 mm to 3.0 mm, with 1.2 mm, 1.5 mm, and 2.0 mm being common stock options. |
| Gutter Dimensions | Customizable. Common widths range from 300 mm to 1200 mm, with single-piece lengths up to 12 meters or as required. |
| Zinc Coating | Hot-dip galvanized. Standard coating mass can be ≥275 g/m² (total both sides). For critical components like brackets, a minimum local thickness of 85 μm is recommended. |
| Corrosion Resistance | Can withstand ≥1000 hours of neutral salt spray test without red rust, suitable for industrial and harsh environments. |
| Design & Fabrication | Supports customized bending, pressing, and fabrication to adapt to different roof slopes and connection needs. Integrated, one-piece stamped designs are available for enhanced stability and easier installation. |
Applications & Key Advantages
Primary Applications:
-
Industrial & Commercial Buildings: Used in large-span steel-structure factories, warehouses, and shopping malls that require durable drainage systems capable of handling high-intensity rainwater runoff.
-
Agricultural Facilities: A standard component in modern multi-span greenhouses, where integrated galvanized gutter brackets are crucial for supporting the drainage system and overall structure.
-
Residential & Public Projects: Applied in villas, high-rise residential buildings, schools, and sports venues to meet functional drainage needs while maintaining aesthetic coherence with the building exterior.
