AA3105 H24 0.027″ Aluminum Gutter Coil

1. Product Overview

AA3105 H24 0.027″ Aluminum Gutter Coil is a premium manganese-alloy aluminum coil specially engineered for residential and commercial rainwater drainage systems. Manufactured in strict accordance with ASTM B209 industry standards, this 0.027-inch thick aluminum gutter coil features optimized H24 semi-hard temper, balancing moderate tensile strength, excellent ductility and outstanding weather resistance. Different from ordinary 1000-series pure aluminum coils, 3105 alloy with manganese element added delivers higher structural stability and impact resistance, perfectly adapting to long-term outdoor exposure, bending forming and on-site processing of gutter systems. It is the most cost-effective and widely recognized core material for seamless aluminum gutters in the construction industry.

Superior Weather and Corrosion Resistance

AA3105 aluminum alloy forms a dense natural oxide film on the surface, which effectively resists oxidation, rainwater erosion, ultraviolet radiation and salt spray corrosion. It performs stably in coastal, humid, high-temperature and harsh outdoor environments, avoiding rust, peeling and deformation that plague iron and ordinary aluminum materials. The coated version further enhances anti-aging performance, ensuring long-term outdoor service life up to 20–30 years.

Balanced Strength and Excellent Formability

H24 semi-hard temper provides moderate hardness and toughness, higher structural strength than 3003 aluminum coil, not easy to dent or deform under external impact. Meanwhile, it retains excellent bending and rolling performance, supporting one-time seamless forming of gutters without cracking or wrinkling during processing. It fully adapts to on-site rapid processing and customized shaping of various gutter specifications.

Lightweight and Structural Saving

The aluminum gutter coil features low density and light weight, which will not cause excessive load on roof and building walls. It effectively reduces the overall structural pressure of the building, eliminates hidden dangers of roof collapse caused by heavy drainage systems, and is safer and more reliable for long-term building use.

Durable Surface and Color Retention

Optional PE and PVDF high-performance coatings have strong adhesion and scratch resistance. The surface is smooth and flat, not easy to fade, chalk or peel. It maintains uniform color and beautiful appearance for a long time, matching various architectural styles, and greatly reduces later maintenance and replacement costs.

Excellent Processability and Seamless Effect

Uniform material texture and stable mechanical properties ensure consistent processing effect. The coil can be continuously rolled and formed to produce seamless gutters, effectively solving the water leakage problem of traditional spliced gutters, improving the sealing and drainage efficiency of the drainage system.
