in our lives
These color steel houses can be seen everywhere
Such as temporary housing on the construction site, temporary garden construction, etc
It is fast to build and low cost
Maintenance is relatively simple
It is the perfect choice for building temporary buildings
But these ubiquitous color steel houses
But there is a fatal hidden danger
What is a color steel plate house?
It is named because there is a layer of color-coated iron sheet on the outer layer, which has the characteristics of light weight, high strength and convenient installation, and is widely used in temporary housing on the construction site of construction projects because of its simple construction and low cost. There are three main core materials: polystyrene, polyurethane and rock wool.
The main material of the temporary house at the construction site is polystyrene and polyurethane sandwich color panels. Although the price is low, the ignition point is low, the flame retardancy is poor, and a large amount of smoke and toxic gases will be produced when burned.
Among them, the fire hazard of the sandwich color plate produced with polystyrene foam material is larger, once the fire is ignited, the foam burns in the middle, the fire extinguisher and water are difficult to extinguish, and the polystyrene combustion will also produce a large amount of black smoke that cannot be emitted, which further increases the difficulty of personnel evacuation.

Fires in color steel houses occur from time to time
Serious casualties and property damage were caused
Related Cases
At 14:04 on November 20, 2023, a fire broke out in a single-story steel structure simple board house of an individual industrial and commercial household on Cross Street, Fengle Town, Zhaozhou County, Daqing City, Heilongjiang Province, with a fire area of 280 square meters, causing 7 deaths. The cause of the fire was preliminarily determined by the relevant departments to be an accidental fire accident. The building that caught fire was built privately by villager Meng in the courtyard of his relatives, and was used daily to store yellow paper for sacrifices.
At about 17 o'clock on October 31, 2023, a fire broke out in a prefabricated house at a construction site in Qingxiu District, Nanning City, Guangxi.
Fire hazards in color steel plate houses
01 Use illegal materials to build
On the premise of considering the cost, the temporary houses in some construction sites and the illegal building core materials of some enterprises are mostly made of flammable materials such as polystyrene and polyurethane foam, and the fire prevention and safety of these flammable and combustible sandwich materials are poor, and electrical welding sparks, cigarette butts, etc. can make the material burn.
02 Fast burning
Once the flammable and combustible sandwich material catches fire, the combustion speed is very fast, and it will produce molten deformation and dripping at 80 °C, and the dripping will cause more serious combustion, and the combustion products will burn wherever they drop, and the combustion products are highly toxic.
03 It is difficult to extinguish fires
The color steel plate house using flammable and combustible sandwich materials, the fire spreads very quickly after the fire, and it is easy to collapse in a short time, and the color steel plate house after the collapse is wrapped in iron sheet on the surface, and it is difficult for the water gun to shoot water into the interior when extinguishing the fire, which will greatly increase the difficulty of fire fighting and rescue work.
04 It is difficult for the trapped people to escape
Polystyrene and polyurethane are accompanied by black smoke when burning, and toxic smoke accumulates inside the room, making it difficult for the trapped people to survive and prone to casualties.
According to the requirements of the national "Code for Fire Protection Design of Buildings", when the building really needs to use metal sandwich panels, the core material should be non-combustible materials, and the fire resistance limit should meet the relevant regulations. Kindergartens, nursing homes, hospitals, collective dormitories and other crowded places shall not be built with color steel plates that are lower than the non-combustible requirements.
For your safety
When choosing a color steel plate house
Please follow the national standards
Choose a color steel plate house with high combustion performance grade
At the same time, you should pay attention to these safety matters in your life
The color steel plate is best made of rock wool board and fireproof cotton as filler, and it can meet the conditions of fire safety on the construction site when it reaches above the A-level fireproof and fire-resistant limit.
In the process of use, some heat sources and fire sources should not be close to the color steel plate, and a certain distance should be maintained. If you want to set up a kitchen in the color steel plate room, you need to have a thermal insulation layer, and the wall should be equipped with a fireproof rock wool insulation layer.
Wires and cables should not be crossed from the color steel plate, if you need to cross, you should add a protective sleeve, and the socket and switch box should be made of metal galvanized box and adopt the surface-mounted method. Indoor and outdoor equipment should be equipped with simple fire extinguishing equipment, and fire alarms should be installed if conditions permit, so as to facilitate the rapid evacuation of personnel.
Keep a safe distance of at least 6 meters between color steel houses. Do not set up iron fences, billboards and other obstacles that affect escape and fire fighting and rescue in violation of regulations.
