Product Description
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.
