As a leading manufacturer established in 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in producing high-quality aluminum ceiling grilles designed for demanding environments. Our 1.2mm Anodized Aluminum Ceiling Grille is engineered specifically for coastal applications where standard grilles quickly succumb to salt spray and humidity. With an annual export value of US$5–10 million, we supply reliable ventilation solutions to markets worldwide, including North America, Europe, and Southeast Asia.
This grille combines precision engineering with superior corrosion resistance, ensuring long-term performance in marine climates. The anodized surface treatment creates a protective oxide layer that withstands harsh coastal conditions without peeling or fading. Whether you need a standard square grille or a custom shape for a specific architectural design, our factory offers flexible options to meet your project requirements.

Frequently Asked Questions
-
Q: Is the 1.2mm thickness strong enough for large ceiling openings?
A: Yes, aluminum alloy 6063-T5 offers high strength-to-weight ratio. For spans up to 1200mm, 1.2mm is adequate. For larger openings, we can recommend thicker material or add reinforcement. -
Q: Can I get a custom color besides silver?
A: Absolutely. We offer a range of standard colors (white, gray, black) and can match any RAL color for anodized or painted finish. Please specify your color requirement. -
Q: How does the anodized coating compare to powder coating in salt spray resistance?
A: Anodizing provides superior corrosion resistance because it forms an integral part of the aluminum substrate. It does not peel or chip like paint, making it ideal for coastal use. -
Q: What is the lead time for custom orders?
A: Typical lead time is 15–25 working days, depending on quantity and complexity. For urgent projects, we can expedite production upon request. -
Q: Do you provide installation instructions?
A: Yes, each order includes mounting guidelines and recommended fasteners. Our grilles are designed for easy installation with standard tools. -
Q: Can the grille be used in outdoor applications?
A: While primarily designed for indoor ceiling use, the anodized finish makes it suitable for covered outdoor areas (e.g., beachfront pavilions). For direct exposure to rain, we recommend our fully weatherproofed version. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ for standard sizes is 50 pieces. For custom sizes, MOQ may be 100 pieces. We can discuss smaller quantities for sample orders. -
Q: How do I clean the grille in a coastal environment?
A: Rinse with fresh water periodically to remove salt deposits. For stubborn dirt, use a mild detergent and soft cloth. Avoid abrasive cleaners.
