Fire rated glass door manufacturers

Buyers must distinguish between Integrity (E), which prevents flames and hot gases from passing, and Insulation (EI), which also limits heat transfer. Common standards include UL 10B/10C (North America), EN 1634-1 (Europe), and BS 476 (UK/Middle East). Ensure the door has a rating of at least 30, 60, 90, or 120 minutes based on local building codes.

The glass should be monolithic potassium-cesium fireproof glass or multi-layer intumescent laminated glass. Frames must be constructed from galvanized steel, stainless steel, or specially treated aluminum profiles with a thickness of at least 1.5mm to 2.0mm. Always request third-party test reports from labs like Intertek, SGS, or TUV.

All hardware, including hinges, door closers, and panic bars, must be fire-certified. Standard aluminum or plastic hardware will melt and compromise the fire barrier. Look for UL-listed or CE-marked self-closing mechanisms and intumescent fire seals that expand when exposed to heat to seal gaps.

Yes, suppliers on Made-in-China.com offer customization for frame colors (RAL powder coating), glass tints, and frosted patterns. However, any modification to the glass size or frame structure must remain within the parameters of the original fire test certification to ensure compliance.

Utilize the Secured Trading Service on Made-in-China.com to protect your payments. Conduct a factory audit or hire a third-party inspector to verify the supplier's ISO 9001 certification and production capacity before transferring large deposits.

Fire-rated glass is heavy and fragile. Insist on fully enclosed fumigated wooden crates with shock-absorbing foam corner protectors and vacuum-sealed plastic wrapping to prevent moisture damage to steel frames during sea freight.

Verify the HS Code (typically 730830 or 700721) with your customs broker. Be aware that some regions impose anti-dumping duties on steel or glass products. Ensure the supplier provides a Certificate of Origin and a Declaration of Conformity to avoid clearance delays.

Focus on long-term compliance and certification stability rather than just the lowest price. Ask for a breakdown of the glass vs. frame cost and negotiate based on volume tiers. For large projects, request a pre-shipment inspection (PSI) to ensure the final product matches the certified sample.
