3003 H24 Alloy Wood Grain Aluminum Slat, Weatherproof Coating for Outdoor Roller Blinds

Product Introduction

Custom-manufactured as dedicated raw material for exterior roller blinds, louvered shutters and venetian blind slats, this color coated aluminium stripe adopts prime 3003 H24 Al-Mn alloy as the core substrate. Processed via high-precision continuous rolling and thermal transfer wood grain coating, it integrates lifelike natural wood visual texture with the durable mechanical properties of aluminum alloy.

The 3003 H24 temper delivers balanced tensile strength and ultra-high bendability, which prevents cracking during repeated cold bending, edge curling and blind roll forming, perfectly fitting automated blind production lines. Compared with natural solid wood, the thermal transfer coated surface eliminates common defects including moisture swelling, mildew, deformation and termite infestation. The finished wood grain pattern reaches over 98% simulation fidelity, compatible with modern minimalist, Nordic and retro architectural interior & exterior decoration styles.

All surface coatings pass rigorous QUV accelerated weathering tests, featuring outstanding UV resistance, scratch resistance and chemical corrosion resistance. It maintains a gloss retention rate above 95% after long-term outdoor exposure, with no peeling, chalking or color fading. Meeting RoHS and REACH international eco-friendly standards, this non-toxic, fully recyclable aluminium stripe is the preferred raw material for long-service-life roller blinds used in residential balconies, commercial office buildings, hotel exterior sunshade systems and industrial ventilation shutters.

V FAQ (Frequently Asked Questions)

   1.Q: Will the wood grain coating fade over time?

      A: No. The product adopts high-durability thermal transfer coating with UV-resistant additives. Passed 1000-hour QUV accelerated aging test, the color fading rate is ≤5% after 8 years of outdoor use.

   2.Q: Can it be customized to specific sizes and wood patterns?

   A: Yes. Thickness (0.3-2.0mm) and width (10-100mm) can be customized. We offer over 20 standard wood grain patterns (oak/walnut/pine) and support custom pattern matching with sample provided.

   3.Q: Is it suitable for bathroom or coastal areas?

   A: Absolutely. The 3003 H24 alloy and thickened coating achieve salt spray resistance ≥1000 hours, effectively resisting moisture, humidity and salt corrosion, ideal for bathrooms, coastal buildings and other harsh environments.

    4.Q: How to maintain the aluminium stripe?

       A: Regular maintenance is simple: wipe with a soft cloth dipped in neutral detergent to remove dust and stains.  Avoid using abrasive cleaners or sharp tools to prevent coating damage.

    5.Q: What is the installation method?

       A: Compatible with standard shutter window installation: slot insertion, screw fixation or clip-on assembly. It can be cut on-site according to actual needs, and the lightweight design reduces installation difficulty.

    6.Q: Does it have impact resistance?

      A: The 3003 H24 temper provides moderate strength (tensile strength 180-220MPa), which can withstand daily slight impacts. For severe impact, the bent slats can be easily restored or replaced individually.
