As an aluminum gutter coil supplier, we BCM Aluminum focus on the advantages of aluminum (lightweight, corrosion resistance, and easy processing) and the application requirements of gutter applications (drainage efficiency, weather resistance, adaptability, and aesthetics). We offer a comprehensive gutter coil product offering encompassing "basic coils + upgrade features + supporting services" to meet the needs of diverse customers (such as construction contractors, gutter fabricators, and building material distributors).

Alloys of Aluminum Gutter Coil

1. Pure Aluminum Gutter Coil (1050/1060 Series)

Purity ≥ 99.5%, soft texture, easy cutting/bending, lightweight, and low cost, suitable for small residential guttering (single-family/low-rise) and temporary building drainage.

2. Aluminum Alloy Gutter Coil (3003 Series)

This manganese alloy offers 30% higher strength than pure aluminum and excellent corrosion resistance (resists oxidation by rainwater). Suitable for guttering in mid- to high-rise residential buildings and commercial podiums (requires load-bearing and wind-resistant applications).

3. High Corrosion-Resistant Aluminum Alloy Coil (5052 Series)

This magnesium alloy offers excellent salt spray and moisture resistance (resists seawater corrosion). Suitable for coastal buildings and areas with high rainfall and humidity (such as the plum rain season in southern China).

Specification of Aluminum Gutter Coil

- Thickness Range:

0.3mm-1.2mm (covering various load-bearing requirements)

0.3-0.5mm: Suitable for small gutters (width ≤ 150mm);

0.6-0.8mm: Mainstream specification, suitable for medium- to large-sized gutters with widths of 150-250mm;

1.0-1.2mm: Heavy-duty gutters (such as those in industrial plants and large commercial complexes, requiring snow and fallen leaves).

- Width Specifications:

Standard Widths: 1220mm, 1500mm (compatible with common gutter processing equipment, reducing cutting waste);

Custom Widths: Can be cut to size based on the customer's desired "unfolded dimensions" (e.g., a 200mm gutter can be supplied in 450mm wide coils, which can be directly bent and formed, reducing processing costs).

Surface Treatment of Aluminum Gutter Coil:

- Anodized Aluminum Coil:

A 5-10μm oxide film forms on the surface, offering high hardness (scratch resistance) and UV resistance (no fading even after prolonged exposure). Available in silvery white and bronze, it's ideal for high-end residences/villas seeking a metallic finish.

- Powder-Coated Aluminum Coil:

Using environmentally friendly powder coating (RoHS compliant), custom colors are available (such as dark gray, off-white, and brown to match the building's exterior color). It offers strong adhesion (resists chipping) and superior weather resistance to conventional spray paint, making it ideal for commercial buildings requiring a uniform appearance.

- Fluorocarbon-coated aluminum coil:

This highest-grade surface treatment, featuring a fluorine-containing resin coating, offers exceptional weather resistance (lifespan ≥ 20 years) and resistance to acid rain and oil stains, making it suitable for use in extreme outdoor environments (such as plateaus and industrial areas).

As an aluminum gutter coil supplier, we offer pre-coated aluminum coils with excellent weather resistance and a variety of colors, making them suitable for exterior applications. We also provide samples for customer evaluation and testing to ensure our products meet your needs.
