Steel corridor fire-rated single swing door

High-quality cold-rolled hot-dip galvanized steel sheets are used for the door frame, door leaf panels and framework. The fireproof boards filled inside the door leaves feature low bulk density, high refractoriness, strong heat insulation, high compressive strength, low thermal conductivity, non-combustibility, non-toxicity, odorlessness and non-pollution. They are also equipped with hardware accessories that comply with relevant regulations. The technical indicators meet the requirements specified in GB 12955-2008 Fire Doors.

Features

The material is sturdy and durable.

The door frame, door leaf panels and framework are made of cold-rolled hot-dip galvanized steel sheets, which are highly corrosion-resistant and pressure-resistant, and not easy to deform.

Core function of fire protection and heat insulation

The fireproof boards also have excellent heat insulation properties, which can prevent the spread of fire and the conduction of high temperatures, buying time for evacuation.

Safe, environmentally friendly and compliant

The technical indicators are fully in line with the national fire door standards, have passed professional testing, and meet the requirements for building fire protection acceptance.

The structure is suitable for corridor scenarios.

It is equipped with compliant hardware accessories, ensuring smooth opening and closing, as well as good sealing performance after closure, which further enhances the fire and smoke insulation effect.
