钢质防火门

F1 · 2 门型

钢质防火门是建筑被动防火体系里最基础的一环。它封闭防火分区的洞口,在项目要求的耐火时限内阻挡火势与烟气,同时要承受楼梯间、走廊、管井和设备机房的高频通行。我们的钢质系列覆盖单扇、双扇、带视窗与不带视窗、喷涂或木纹饰面等配置,并按整樘门供货:门扇、门框、闭门器、合页、锁具与膨胀密封条齐全。每樘门按项目门窗表上的洞口尺寸生产,门框适配结构洞口,避免现场二次改装。耐火等级、五金品牌与表面处理按工厂针对目的国市场持有的证书确认。

选型要点

  • 先按防火分区确定耐火等级,再看产品目录:楼梯间的要求通常高于走廊隔墙。
  • 按整樘成套订购(门扇+门框+五金+密封条)。有证门扇配上无证五金,整樘门就不具备认证性能。
  • 高频通行的走廊建议配带背查功能的闭门器,并与火灾报警联动的常开释放装置。
  • 下料前确认墙体类型:砌体、轻钢龙骨隔墙与钢龙骨洞口需要不同的门框型材与固定方式。

常见问题

Do you supply the door and the frame together?
Yes. Sets are quoted as leaf, frame, hardware and seals, made to the opening size on your schedule. Supplying the two separately is the most common cause of site delays.
Can the leaf carry a vision panel?
Yes, glazed apertures can be factory-fitted. The glass type must match the rating class of the assembly, so it is specified together with the door rather than added later.
Which documents come with an order?
Test reports and certificates the factory holds for the ordered configuration, plus packing lists and drawings for approval. Certificates are only stated for configurations actually covered.
Can we order one set as a sample?
Sample quantities are handled case by case. Send the opening size and rating so the factory can confirm what is feasible before an order is placed.
