1. There are differences in materials.

木制防火門是木制的。門框、門板一般都采用木材，其耐火性能符合有關規定。

Wooden fire doors are made of wood. Wood is generally used for door frame and door panel, and its fire resistance meets relevant regulations.

鋼制防火門是鋼制的。除門框外，其骨架、面板、填料等均要求為的防火保溫材料，其次為五金配件，形成符合規定的防火門。

Steel fire doors are made of steel. In addition to the door frame, its skeleton, panel, filler, etc. are required to be non-toxic and environment-friendly fire insulation materials, followed by hardware accessories to form a fire door that meets the regulations.

2.安裝上存在差異。

2. There are differences in installation.

木質防火門安裝時，門框規格距洞口小于20mm，門框埋入地下20mm。門框與墻面固定牢固，立框與支撐架應平直，角度一致，防止刨距。門框兩側不少于三個固定點，間距不超過800mm。

When installing wooden fire doors, the door frame specification shall be less than 20mm from the opening, and the door frame shall be buried underground for 20mm. The door frame shall be firmly fixed to the wall, and the vertical frame and support frame shall be straight with the same angle to prevent planing distance. There shall be no less than three fixed points on both sides of the door frame, and the spacing shall not exceed 800mm.

鋼制防火門安裝時，應考慮門框的彎曲變形。門框的寬度方向需要木支撐。門框應埋在地下20 mm處。嵌入門框和墻壁中的部件應進行焊接。門框上方的墻壁應打開，并用摻有水泥、砂和膨脹珍珠巖的混凝土填充。固化后即可使用。

When installing the steel fire door, the bending deformation of the door frame shall be considered. The width direction of the door frame needs wood support. Door frames shall be buried 20 mm underground. Components embedded in door frames and walls shall be welded. The wall above the door frame shall be opened and filled with concrete mixed with cement, sand and expanded perlite. It can be used after curing.

3.性能要求存在差異。

3. There are differences in performance requirements.

木質防火門門框及厚度應大于50mm，門扇采用雙榫連接。門框與門扇拼接時，榫槽應嵌緊，用橡膠拼接，用橡膠楔固定。

The frame and thickness of wooden fire door shall be greater than 50mm, and the door leaf shall be connected with double tenon. When the door frame is spliced with the door leaf, the tenon and groove shall be embedded tightly, spliced with rubber and fixed with rubber wedge.

鋼制防火門門扇與門框的搭接不小于10mm，兩側門扇與門框的間隙不大于4mm。安裝后間隙不得過大。密封性能將受到影響，火災和煙霧將無法被阻止。

The overlap between steel fire door leaf and door frame shall not be less than 10mm, and the gap between door leaf and door frame on both sides shall not be more than 4mm. The clearance shall not be too large after installation. The sealing performance will be affected and fire and smoke will not be stopped.
