Explore our export-certified architectural window series manufactured to AS2047, CE, and international fire-safety standards.
Direct factory engineering eliminates split liability. We manage aluminum profile extrusion, thermal break insertion, fire-resistant glass lamination, and precision CNC fabrication under one quality management system.
Our structural frames utilize high-grade 6063-T5 aluminum extrusions, structurally reinforced with PA66GF25 polyamide thermal barriers. This eliminates thermal bridges, drastically lowers building operational HVAC loads, and resists structural warping under intense heat exposure.
We combine multi-layer laminated intumescent gel glass (EI Integrity & Insulation) and clear non-insulated fire-resistant glass (E Integrity). Upon fire exposure, the gel transforms into an opaque thermal shield, stopping thermal radiation dead in its tracks.
Equipped with heavy-duty Siegeina, Roto, or HOPPE hardware, our operable fire windows feature automatic thermal-link closure mechanisms. In the event of ambient temperature spikes above 68°C, window sashes seal automatically to preserve compartmentation integrity.

As international building codes (such as the International Building Code (IBC), European EN Standards, and Australian National Construction Code (NCC)) tighten structural safety and energy efficiency parameters, the global demand for fire-rated windows manufactured in China has shifted from basic code compliance to highly integrated, multi-functional fenestration systems. Procurement direct from Chinese manufacturing hubs now requires a nuanced understanding of metallurgical advancement, glass chemistry, and smart architectural integration.
Historically, fire windows suffered from aesthetic compromises: thick, heavy steel profiles with wire-reinforced glass that resembled industrial enclosures rather than luxury architectural facades. Modern Chinese wholesale factories have revolutionized this product category through three core innovations:
B2B buyers, architectural specifiers, and volume importers sourcing from China Wholesale Fire Windows Factories are adjusting their procurement strategies to align with changing global market dynamics:
To mitigate risk when establishing wholesale factory contracts, overseas buyers must implement strict vendor audit protocols. A legitimate China Fire Windows Manufacturer must provide comprehensive documentation beyond basic factory business licenses:
Expert answers addressing structural engineering, certification compliance, shipping logistics, and material specifications.
Grade E (Integrity) prevents flames and hot gases from passing through the glass for a specified time (e.g., 30, 60 min), but allows radiant heat to pass through. Grade EI (Integrity & Insulation) stops flames AND blocks radiant heat transmission entirely, keeping the non-fire side cool to touch. EI grade is required for escape routes and fire-rated barrier walls.
Yes. Top-tier Chinese export manufacturers produce systems engineered to meet US (ASTM E119, UL 9, NFPA 80), European (BS EN 1634-1, EN 1364), and Australian (AS1530.4, AS2047) standards. Factory test reports and shop drawings can be submitted directly to local Authorities Having Jurisdiction (AHJ) for project approval.
We use architectural-grade 6063-T5 aluminum alloy for precision frame extrusion. For higher structural strength and extended fire ratings (EI60/EI90), internal steel reinforcement cores or specialized fire-retardant ceramic core inserts are built directly inside the multi-chamber profile.
Yes. Operable fire windows are fitted with thermal-fusible link hinges or electric chain actuators connected to the building's fire alarm system. Upon detecting temperatures over 68°C or receiving a signal from the smoke alarm system, the window automatically closes and locks into multi-point keepers.
Standard architectural aluminum profile orders take 2 to 3 weeks. Custom fire-rated insulated glass units requiring specialized laminating and third-party laboratory inspection certificates typically ship within 4 to 6 weeks from initial deposit and final BIM/shop drawing sign-off.
Products are packed in custom-built, fully enclosed, IPPC-stamped fumigated plywood crates. Each glass panel is separated by anti-vibration cork pads and wrapped in plastic shrink film with desiccant bags. Crates are loaded via fork-lift guides into 20GP or 40HQ heavy-duty shipping containers.
