Fire doors need to be cleaned and maintained after prolonged use. So how do we clean and maintain fire retardant doors? Let the fire retardant door manufacturers guide you.
Clean foreign objects on the surface of the fire retardant door
This cleaning work is the most basic and can be done by anyone. It doesn't take much time. When cleaning the surface of the fire retardant door, use a cloth dipped in clean water or soapy water to gently wipe off the dust, impurities, rust, and other foreign objects attached to the surface of the fire retardant door.
Inspect the hardware components of the fire retardant door
The role of hardware components in fire retardant doors is self-evident. Once the components are damaged, the effectiveness of the fire retardant door will be compromised. Therefore, the inspection of fire retardant doors must be included in the maintenance plan. When inspecting fire retardant doors, it is best to hire professional technicians or experienced personnel. If any damage is found, repairs or replacements must be carried out promptly.
Pay attention to maintenance
Regularly check the integrity of fire retardant doors, including the fire retardant door material itself, whether the door closer and sequencer are functioning properly, and whether the fire retardant door can close in order. Check if the screws on the hinges and pivot hinges are loose. If any damage is found, immediate repairs should be organized.
Currently, many places choose fire retardant doors for decoration because they are safe and practical. However, the selection of fire retardant doors also requires attention. So, what should be considered when choosing fire retardant doors?
Check the appearance
A high-quality fire retardant door should have firm and evenly distributed welds. The surface should be sprayed smoothly. There should be product labels, quality inspection qualification marks, and quality certification marks in designated locations. A qualified wooden fire retardant door should have an intact appearance without any damage. The surface should be clean and free of planing marks, burrs, and hammer marks. The corners and seams should be tightly and smoothly joined.
Check the numbers
The dimensions of qualified products should be equal to or smaller than the dimensions described in the sample description. The thickness of the door leaf should be equal to or greater than the thickness described in the sample description. The width of the side walls of the door frame should be equal to or greater than the width described in the sample description. The dimensions of the fire-resistant glass should be equal to or smaller than the dimensions described in the sample description, and the thickness of the fire-resistant glass should be equal to or greater than the thickness described in the sample description.
Check the seals
Qualified steel and wooden fire retardant doors should be equipped with fire-resistant seals. The seals should be straight and not arched, and there should be a qualified test report issued by a national-level testing organization.
Estimate the weight
High-quality fire retardant doors are generally heavier, while those that are very light are definitely inferior in quality.
Check the certificates
Fire doors, including 6 panel interior fire doors, are products that are covered by the type approval system. The products need to undergo type approval testing before they are sold. Generally, the type approval report describes the specifications, dimensions, composition, materials, and photos of the sample in detail. When purchasing, you should request the type approval report from the manufacturer.
