Steel and Wood Fire-resistant Door

Product Overview

The Steel And Wood Fire-resistant Door QA-BXG-003 is a dual-functional architectural solution that combines fire protection, sound insulation, and decorative aesthetics. Blending the structural strength of steel with the natural beauty of wood, this door meets strict fire safety standards while enhancing the visual appeal of any space. Designed for civil and industrial buildings, the steel-wood composite fire door offers reliable fire resistance, effective noise reduction, and versatile decoration, making it a top choice for spaces requiring safety and style.

Structure & Materials

Steel-Wood Composite Frame

The frame adopts a high-strength steel × solid wood composite structure: the inner steel frame provides structural stability and fire resistance, while the outer solid wood layer adds natural texture. The steel frame is made of thickened steel plate (2.0mm thickness), ensuring the door remains intact and non-deformable during fires. The solid wood layer is selected from high-quality hardwood, offering excellent durability and decorative potential.

Fireproof & Soundproof Filling

Inside the door leaf, premium fireproof materials—fireproof rock wool and perlite—are filled to achieve thermal insulation and flame retardancy. These materials prevent fire and smoke spread, meeting customized fire resistance limits. Additionally, the combination of wood and fireproof filling provides secondary sound insulation, reducing external noise interference effectively.

Surface Decoration Materials

The wood surface of the door can be processed with varnish or dyeing treatments, available in multiple colors and textures. The surface is smooth and wear-resistant, integrating seamlessly with modern minimalist, classical Chinese, and other decoration styles. The thin steel panel inside the door leaf enhances structural strength without compromising the wood’s natural aesthetics.

Key Performance Features

Fire Resistance & Smoke Blocking

The fireproof rock wool and perlite filling, combined with the steel frame, effectively block flame spread and smoke penetration. The door meets national fire resistance standards, providing valuable escape time in emergencies. The steel structure remains stable at high temperatures, ensuring the door’s integrity and sealing.

Effective Sound Insulation

The steel-wood composite structure and dense filling materials reduce external noise by 25-35 dB, creating a quiet indoor environment. It is suitable for places requiring both fire protection and sound insulation, such as hospitals, schools, and hotels.

Elegant Decorative Adaptability

The natural wood surface, available in various treatments, complements different architectural styles. Whether installed in modern offices or classical buildings, the door enhances the overall decorative effect without sacrificing functionality.

Stable Security & Durability

Equipped with durable anti-theft door locks and high-load-bearing hinges, the door offers reliable security. The hinges ensure smooth opening and closing, with a load-bearing capacity of ≥80kg, supporting long-term stable use. The steel-wood structure resists dampness, moth-eaten, and deformation, extending the door’s service life.
