ABSRTACT: Color Steel House is a kind of simple housing which is often used on the construction site. It is made of Color Steel Compound Board (also called Color Steel Sandwich Board) as wall and light steel structure as skeleton. Can Be easily and quickly assembled and disassembled, but the fire protection is much worse, and summer is too hot, winter is too cold, is not suitable for long-term living.

Color steel house

Color Steel house is a light steel h-beam, channel steel as the skeleton, Sandwich panel as the wall material, to the standard modulus series for the space combination, components using bolt connection or welding, environmental protection and economic housing. It can be assembled and disassembled conveniently and quickly, realizing the universal standardization of temporary buildings, and establishing the architectural concept of environmental protection, energy saving, quick and efficient, temporary housing into a series of development, integrated production, supporting the supply, inventory and can be used for many times in the field of stereotypes.

What are the materials used to build the color steel house

Color Steel house is made of Color Steel Composite Plate (also known as Color Steel Sandwich Plate) for the wall, light steel structure for the framework of the building. Color Steel Composite Board (hereinafter referred to as: Color Board) according to the core material is divided into: Polyurethane Sandwich Board, Rock Wool Sandwich Board, Polystyrene (EPS) Sandwich Board, Glass Wool Sandwich Board, etc. .

The shell of color plate is color coated steel plate, which is a kind of steel plate with organic coating.

Characteristics of Color Steel Plate

  1. Light weight: 10-14kg/m2, equivalent to 1/30 of brick wall
  2. Thermal insulation and heat preservation: thermal conductivity of core material: λ<=0.041w/mk
  3. High strength: it can be used as ceiling envelope structure plate load-bearing, bending and compression resistance; general houses do not need beams and columns
  4. Bright color: no need for surface decoration, color galvanized steel corrosion layer maintenance period in 10-15 years.
  5.  Flexible and quick installation: construction cycle can be shortened by more than 40%.
  6. Oxygen index: (OI) 32.0 (provincial fire product quality inspection station).

Composition and application of color coated steel sheets

The substrates of color coated steel sheets are cold rolled substrates, hot dip galvanized substrates and electro galvanized substrates. The coating types can be divided into polyester, silicon modified polyester, bi-poly difluoroethylene and plastisol. The surface state of color coated steel plate can be divided into coated plate, embossed plate and printed plate, color coated steel plate is widely used in construction, home appliances and transportation industries, for the construction industry is mainly used for factory buildings, airports, warehouses and refrigeration and other industrial and commercial buildings such as roof walls and doors, civil buildings using color coated steel plate is less. It is different from plastic steel because the composition of the material is different. Iron-absorbing stone can be sucked.

The form of color steel plate: before forming is a coil, after forming the model is a lot, the most commonly used is: 820 type, 840 type, 900 type, etc.! Its composition structure is: protective film (now the product does not have), polyester paint, galvanized layer, steel plate (divided into cold-rolled plate and hot-rolled plate), the back of the same order!

Advantages and disadvantages of color steel house

The first point, the advantage of simple housing, is the speed. Compared with the traditional housing to months of construction and decoration time, simple color steel house fast three or five days slow half a month can be moved in, not a little bit faster.
The second benefit of the simple color steel house is that it saves money. Our traditional housing, the cost of labor are more than 10,000 20,000 or so. An 80 square foot house will cost more than 100,000 yuan to build. Whereas the simple color steel house? Seventy to eighty thousand yuan, you can build an 80 square foot house. Save a third of the cost.
Then there are advantages and disadvantages, although the simple color steel house is fast to build, and relatively low price of the traditional brick house. But the simple color steel house of fire prevention effect is very poor, if not pay attention to the fire is very easy to cause. There are also simple housing insulation board is not very environmentally friendly materials, as to whether there is a danger to the human body, there is no clear data to explain. But do not rule out the possibility of harm to human health. And too many years, the airtightness of the simple color steel house will also be affected. The problem of not warm in winter and not cool in summer.
