In the field of building safety, the standardized application of fire doors has always been a high priority. Recently, the question of whether bolts can be installed on fire doors has sparked widespread discussion within and outside the industry. This issue involves multiple aspects, including fire standards, construction, and market regulation.

Safety Responsibilities of Fire Doors

The primary function of fire doors is to prevent the spread of fire smoke and heat and ensure smooth evacuation. According to current standards, fire doors must have automatic closing and fire-resistant isolation features to ensure proper function in emergencies. Any uncertified modifications, especially those involving hardware installation within the door leaf structure, may compromise their overall performance.

Risks of Bolt Installation

• Installing bolts on ordinary doors can improve security, but using them on fire doors presents several potential risks:

• Imprisoned Escape: If the bolt fails to open in time, evacuation may be delayed.

• Violation of Certification: Once a fire door has been modified, the original fire resistance test results will be invalidated.

• Impact on the Structure: Additional drilling or installation can damage the door's filling material, reducing its fire resistance.

Experts and Industry Opinions

Industry experts emphasize that if additional security requirements are truly necessary, specialized fireproof locks or integrated door systems should be selected. Standardized testing should be completed during the production phase to ensure that the product meets both fire protection and security requirements. Furthermore, contractors and users should avoid unauthorized modifications to avoid liability during inspections or fire incidents.

Future Trends and Regulatory Directions

As market demand for comprehensive safety increases, hardware manufacturers are gradually introducing multi-functional latches that meet fire safety regulations. Regulatory authorities are also increasing spot checks and explicitly requiring all hardware components of fire doors to be accompanied by relevant test reports. The industry is expected to move towards greater compliance and standardization in the future.
