The following mainly introduces one of the high-quality products produced by the company: insulated doors.

The instruction of Bast insulated door

Insulation door refers to a door that can meet the requirements of fire resistance stability, integrity and heat preservation within a certain period of time. The steel heat-insulating fire-proof door adopts high-quality cold-rolled hot-dip galvanized steel plate as the door frame and door cotton. The fire-proof door core is filled in the door cotton and equipped with hardware that has passed the national fire test. It can meet the requirements of fire integrity and thermal insulation. Fire doors are suitable for high-rise buildings and civil and industrial buildings with fire protection requirements, such as hotels, restaurants, apartments, warehouses, data rooms, oil depots, computer rooms, power distribution rooms and other places. The thermal insulation performance of the thermal insulation door means that the thermal insulation door needs to be laid with temperature measurement points. When the average temperature reaches 140°C or any temperature measurement point reaches 180°C, the thermal insulation performance will be lost. It has strict fire and airtight requirements, meets the latest fire safety standards, and is equipped with airtight door hinges and compression mechanisms.

The feature of Bast insulated material

There are many kinds of thermal insulation materials, among which the most common thermal insulation materials are inorganic materials such as expanded perlite, aerated concrete, rock wool and glass wool, and organic materials such as polystyrene foam and polyurethane foam. The advantages and disadvantages of these materials are mainly determined by the high and low thermal conductivity of the materials (the index is thermal conductivity). The harder the heat conduction of the material (i.e., the smaller the thermal conductivity), the better the thermal insulation performance. Generally speaking, the common characteristics of thermal insulation materials are light, loose, porous or fibrous, with its internal non-flowing air to block the heat conduction. Among them, inorganic materials have the characteristics of non-combustibility, wide use temperature and good chemical resistance, while organic materials have the characteristics of higher strength, lower water absorption rate and better impermeability.

The advantage of Bast insulated door

1. Good fireproof performance: The heat-insulating door is made of metal material, which is not easy to burn.

2. Good anti-theft performance: The heat-insulated door is equipped with advanced decorative locks and excellent hardware accessories to make it difficult for thieves to steal.

3. Strong sound insulation: the outer surface of the fire door adopts a large-tonnage press and a mold to form it in one step.

4. Good air tightness, warm in winter and cool in summer.

5. Impact resistance: The heat-insulated door frame is made of high-quality steel plate, which has super hardness and stronger impact resistance.

6. A variety of colors: there is plenty of free space for customers to choose.

7. Maintenance-free failure: The heat insulation material is not easy to be corroded by acid and alkali. Damaged doors will not turn yellow or fade during use and require little maintenance.
