High Light pre-painted aluminum gutter coil ，3003 H14 alloy gutter coil ，11.875 inch seamless gutter coil

 

Technical Overview


Specifically engineered for continuous roll-forming of seamless gutters, our aluminum coils utilize high-grade 3000 series alloys to ensure optimal balance between structural rigidity and flexibility. The surface is treated with a multi-stage cleaning and chromating process before the application of high-durability polyester (PE) or polyurethane (PU) coatings.

Impact Resistance: No coating detachment after 50 kg/cm impact.
Pencil Hardness: .
Salt Spray Resistance: hours (ASTM B117 standard) with minimal creepage.
Gloss Level: Customizable from 10% to 80% based on project requirements.


Key Features for Gutter Manufacturers


Zero Cracking: Optimized H14/H24 temper prevents "crazing" or paint fracture at sharp gutter bends and bottom radii.
Uniform Tension: Precision leveled coils ensure zero camber, allowing for consistent feeding into seamless gutter machines.
Weatherability: Advanced UV-resistant pigments prevent chalking and fading in harsh outdoor environments.
Protective Film: Optional clear PE film can be applied to prevent surface scratching during transportation and installation.
