Manufacturing Process

Material Selection:Based on the design requirements for fire doors, we select suitable materials (such as steel, wood, aluminum alloy, etc.) and core materials (such as fire-resistant boards, insulation materials, etc.).

Material Inspection:All purchased raw materials undergo quality inspection to ensure they meet the required standards and regulations.

Design Solution:We design fire doors according to customer needs and building regulations, including size, style, and fire rating.

Technical Review:A thorough technical review of design drawings ensures that the design is reasonable and meets fire safety standards.

Cutting:Selected materials are cut according to the design dimensions and requirements.

Forming:Materials are processed into fire door frames and panels through stamping, bending, and other processes.

Core Filling:Fire-resistant core materials are placed inside the frame to ensure the required fire performance.

Pre-Assembly:We perform the initial assembly of fire door components (frame, door leaf, core material, etc.) to ensure proper fit.

Welding & Fixing:We use welding and bolting to secure all parts of the door, ensuring a sturdy structure.

Anti-Rust Treatment:Metal parts undergo anti-rust treatments such as spraying or hot-dip galvanizing to enhance corrosion resistance.

Surface Coating:The door's surface is coated according to design specifications, providing both functional and decorative finishes.

Dimension Inspection:We check the size and appearance of assembled doors to ensure they meet design requirements.

Fire Performance Testing:Fire performance tests are conducted to verify the fire rating of the doors and ensure they meet relevant standards.

Quality Inspection:Our quality control department performs a comprehensive inspection to ensure the doors meet high-quality standards.

Packaging:Doors are carefully packaged to prevent damage during transportation.

Shipping Arrangement:We arrange for timely delivery based on customer orders, ensuring the products arrive on time.
