Certifications: ISO 9001:2015, REACH, and RoHS certified. Third-party inspection by SGS/TUV is welcomed.

FAQ

Q: Can you customize the size, color, and GSM?

A: Yes. We support full customization of dimensions (up to 2400mm width), specific RAL colors, and weight ranges from 500 to 800 GSM to meet your strength requirements.

Q: How do you ensure consistent quality for large orders?

A: We use 100% virgin PP and conduct in-line thickness & grammage checks every hour. Each batch is issued a COA (Certificate of Analysis) and we welcome third-party inspections (SGS/TUV).

Q: Is the board suitable for outdoor UV exposure?

A: Standard boards are for indoor/short-term outdoor use. For long-term outdoor signage, we can add UV-stabilizer additives to extend the lifespan to 2+ years.

Q: Can the boards be easily fabricated?

A: Absolutely. Our 3mm boards are optimized for die-cutting, sonic welding, stapling, and heat-folding. They do not crack or splinter during high-speed processing.

Q: How do you package the sheets for sea freight?

A: We use non-fumigation pallets with protective edge guards and stretch film. This ensures the boards remain flat and damage-free during long-distance transit.
