0.7mm Thick Aluminum Coil For Gutter
In modern construction and roofing systems, durability and corrosion resistance are critical factors for gutter materials. Our 0.7mm Thick Aluminum Coil for Gutter is engineered to meet the specific demands of residential and commercial gutter systems, combining optimal thickness, superior alloy chemistry, and tempering to ensure longevity under harsh environmental conditions.
Product Description
The 0.7mm thick aluminum coil is a flat-rolled product designed primarily for the fabrication of gutters, downspouts, and related drainage components. Its uniform thickness and excellent surface finish make it highly suitable for forming, welding, and coating operations typical in gutter fabrication.
- Thickness: 0.7 mm
- Width: Customizable (commonly 600mm to 1250mm depending on mill capabilities)
- Length: Supplied in coils or cut-to-length sheets based on customer requirements
- Surface Finish: Mill finish, with options for anodized, painted, or pre-painted coatings
- Alloy Options: Primarily 3004 and 3105 series suitable for gutter applications
Alloy & Temper Selection
To satisfy the rigorous mechanical and corrosion resistance requirements of gutter systems, certain aluminum alloys and tempers are recommended:
Common Alloy Choices
| Alloy | Description | Recommended for |
|---|---|---|
| 3105 | Commercial Aluminum, good corrosion resistance and formability | Ideal for gutters with standard rainwater drainage systems |
| 3004 | Manganese added for increased strength and corrosion resistance | Suitable for higher strength, more complex gutter shapes, and durability |
Temper Grades
| Temper | Description | Application Benefits |
|---|---|---|
| H14 | Strain hardened, part hard | Good formability with moderate strength needed |
| H24 | Strain hardened and partially annealed | Offers balanced strength and ductility for forming while maintaining corrosion resistance |
| O | Annealed, fully soft | Easier forming but lower strength, suitable for delicate shapes |
Physical and Mechanical Parameters
| Parameter | Value / Range | Test/Standard |
|---|---|---|
| Thickness | 0.7 mm | ASTM B209 / EN 485 |
| Width | 600 – 1250 mm (customizable) | |
| Density | 2.7 g/cm³ | ASTM B311 |
| Tensile Strength (YS) | 95 – 145 MPa | ASTM B209 |
| Elongation at Break (%) | 5 – 15% | ASTM B209 |
| Hardness (Brinell or HV) | 30 – 60 | Symbolic |
| Surface roughness | <0.5 micron (Ra) | Custom specification |

| Others | TRACE | TRACE |
Implementation and Manufacturing Standards
The 0.7mm aluminum coil for gutters is manufactured following stringent quality and sustainability standards:
- Standards followed: ASTM B209 (Aluminum and Aluminum-Alloy Sheet and Plate), EN 485 (Aluminium and aluminium alloys — Sheet, strip and plate), AA (Aluminum Association) Specifications
- Surface Treatment: Options include coil coating compliant with AAMA 2604 standards(plastic paints for corrosion and UV resistance)
- Welding Compatibility: Suitable for TIG, MIG, and spot welding techniques with minimal post-weld distortion
Advantages of 0.7mm Aluminum Coil for Gutter
- Corrosion resistance: Aluminum inherently resists rust, making it perfect for wet conditions in gutters
- Lightweight: Reduces pressure on gutter brackets and mounting points
- Formability: The 0.7mm thickness enables smooth roll forming, bending, and fabrication to typical gutter shapes (K-style, half-round, fascia gutters)
- Thermal Expansion: Lower than steel allowing for less deformation with temperature changes
- Aesthetic adaptability: Available for colorful coatings to match exterior designs
- Sustainability: 100% recyclable aluminum enhances eco-friendly building standards
Applications
- Rainwater gutters on residential and commercial buildings
- Downspouts and rainwater drainage channels
- Fascia trimming and flashing
- Decorative roofing trims compatible with otherwise aluminum roofing
