As engineers at BCM Aluminum Canada, with years of experience in exporting color coated aluminum materials to North America, we understand that roller shutter door materials must balance durability, compliance, and cost-effectiveness. AA3105 H26 color coated aluminum coil sheet is our core product, specifically designed for roller shutter applications, tailored to the needs of the North American market and optimized through multiple process optimizations. It perfectly meets the stringent requirements of North American industrial, commercial, and warehousing environments.

Regarding the base material selection, we firmly choose AA3105 aluminum alloy in the H26 temper. This is not a random choice, but the result of repeated verification based on the pain points of roller shutter usage scenarios in North America. AA3105 is an aluminum-manganese-magnesium alloy with an aluminum content exceeding 98%, supplemented with 0.30-0.80% manganese and 0.20-0.80% magnesium. It possesses excellent rust and corrosion resistance as well as mechanical strength, allowing it to withstand the diverse climates of North America without additional anti-corrosion treatment—effectively preventing oxidation and rust in the base material, whether it's the harsh snow and winds of the Northeast or the salty and humid conditions of the Southeast coast, thus extending the lifespan of the roller shutter door from the source. The H26 semi-cold-worked state gives 3105 color coated aluminum coil precise mechanical properties, with a tensile strength of 175-225 MPa and a yield strength of no less than 150 MPa. This ensures structural stability during the rolling process, preventing warping, deformation, or breakage, while retaining appropriate plasticity for subsequent cutting, bending, stamping, and other processing, adapting to various roller shutter door slat designs, balancing strength and processing flexibility.

Coating technology is the core competitiveness of color coated aluminum coils and a key area of optimization for the North American market. We employ a double-coat, double-baking process. The primer is a high-adhesion epoxy primer, and the topcoat is a high-weather-resistance polyester (PE) or fluorocarbon (PVDF) coating. The coating thickness is controlled between 15 and 35 μm, strictly adhering to the US AAMA 2605 international standard to ensure a tight bond between the coating and the substrate, achieving an adhesion rating of 0, making it resistant to peeling and flaking. Addressing the dual needs of North American customers for both appearance and durability, we offer a wide range of colors. All coatings of aluminum for roller shutter door undergo rigorous UV aging and salt spray testing, demonstrating excellent color stability. They are resistant to fading and yellowing within the 20-year warranty period, meeting both the decorative needs of commercial settings and the harsh environments of industrial warehousing. They also comply with North American green environmental standards, releasing no toxic gases and achieving a B1 flame retardant rating, meeting various compliance requirements.

Based on years of experience serving North American B2B customers, we understand that customers are concerned not only with product performance but also with overall cost of use and compliance. AA3105 H26 color-coated aluminum coils have a density of only 0.0983 lb/in³, making them lightweight and significantly reducing the overall weight of roller shutter doors, thus decreasing motor load, energy consumption, and maintenance costs. Their excellent corrosion resistance avoids frequent slat replacements, extending service life by over 50% compared to traditional steel, resulting in a significant long-term cost-performance advantage. Furthermore, the product strictly complies with North American UL 10C fire resistance certification and CSA certification requirements, and its wind pressure resistance meets the PA202 wind load test standard, making it suitable for use in hurricane-prone areas such as Florida and Texas. It also meets Canada's stringent requirements for dual airtightness and watertightness, helping customers easily pass local building code reviews and avoid compliance risks.

As an aluminum processing company rooted in Canada and serving North America, BCM Aluminum always prioritizes technology and is customer-oriented. Our AA3105 H26 color-coated aluminum coils are overseen by a professional technical team at every stage, from base material selection and processing to finished product inspection. We can provide customized thickness (0.25-2.5mm), width, and color schemes according to customer needs, while also offering comprehensive technical support and after-sales guarantees. We firmly believe that professional products and attentive service can provide North American roller shutter industry customers with more efficient, durable, and economical material solutions, working together to achieve mutual success in the North American market.
