The core features of high-quality roll up doors lie in the comprehensive optimization of materials, functionality, and design. Firstly, they predominantly utilize high-strength aluminum alloy or stainless steel profiles, such as 6063-T5 aluminum alloy slats, treated with fluorocarbon spraying or electrostatic powder coating for corrosion resistance and anti-aging properties, ensuring a service life exceeding 20 years. Some premium models adopt a double-layer structure with embedded polyurethane insulation, significantly enhancing thermal performance.
In terms of functionality, intelligence and safety are prioritized: standard infrared anti-collision systems automatically retract upon encountering obstacles; integrated temperature sensors and water spray systems enable fire-resistant models to withstand flames for up to 3 hours; wind-resistant designs feature optional aluminum alloy wind braces to endure winds exceeding Level 12.
Design-wise, space efficiency and aesthetics are emphasized. The roller structure occupies only 30 cm of ceiling space when retracted, with slat surface flatness errors under 0.5 mm, supporting 36 color customization options to meet commercial demands. Additionally, the electric drive system employs servo motors with opening/closing speeds of 0.6–2.0 m/s, paired with UPS backup power for manual operation during outages, balancing efficiency and safety.
