Prepainted Aluminum Gutter Coil

Prepainted aluminum gutter coil is a kind of aluminum coil material with pre-coated surface, which is usually used for drainage ditch, rainwater collection system and other water-related construction and infrastructure projects. Pre-painted aluminum gutter coil has a variety of colors and surface treatment options to meet different design requirements, and also has good corrosion resistance and weather resistance. 3003, 3004, 3105 pre-painted aluminum gutter coil have become ideal materials for gutter due to their corrosion resistance, processability and economy.

Technical parameters of pre-painted aluminum gutter coil:

• Coating type and performance

– Polyester (PE) coating: thickness ≥18μm, gloss 10-90%, hardness ＞2H, adhesion not less than level 1, impact resistance 50kg/cm, service life of about 20 years. Suitable for indoor or light outdoor environment.

– Fluorocarbon (PVDF) coating: thickness ≥25μm, stronger weather resistance, excellent anti-ultraviolet and fading performance, warranty period up to 30 years. Suitable for gutter in coastal areas with high corrosion or strong sunshine.

• Specification range

– Thickness: 0.05-6.00mm (conventional drains are recommended to be 0.6-1.5mm).

– Width: 20-1500mm, special sizes can be customized.

– Color: Support RAL, Pantone color cards and customer sample color matching to meet personalized needs.

• Mechanical properties

– High bending and folding strength, can withstand the changes in climate and wind pressure in four seasons, and is not easy to deform.

– Excellent corrosion resistance, good tolerance to atmosphere, fresh water, seawater and chemical media.

Core characteristics of pre-painted aluminum gutter coil:

• Strong weather resistance

– Adopting high-temperature baking process, the coating has high adhesion and excellent color stability. The polyester coating has a warranty of 10 years, and the fluorocarbon coating has a warranty of more than 20 years, which can resist erosion by ultraviolet rays, acid rain, saline and alkali.

– It is not easy to deform or expand under the temperature difference of four seasons, and adapts to environmental factors such as wind pressure and humidity.

• Rich decoration

– Aluminum gutter coil provide a variety of textures and colors such as wood grain, stone grain, and monochrome, and can customize patterns to meet the needs of personalized architectural styles.

– The surface is smooth without indentation, with high gloss, which improves the beauty of the building.

• Excellent mechanical properties

– High bending and folding strength, not easy to deform during processing, suitable for on-site molding and installation.

– Lightweight material, easy to transport and construct.

• Environmentally friendly and safe

– Resistant to salt, alkali and acid rain corrosion, no release of toxic gases, and flame retardancy meets the national B1 standard.

– Long-term use does not produce toxic bacteria, and avoids rust on the keel and fixings.
