What is color steel plate

 

Color steel plate refers to color coated steel plate, which is a steel plate with organic coating. Color steel plates are divided into single plates, color steel composite plates, floor decks and so on. It is widely used in the wall and roof construction of large-scale public buildings, computer room decoration, public workshops, prefabricated houses, and integrated houses.

 

(1) Advantages of color steel plate

​

1.1 Features

 

1) Color steel plate coating is a product made of cold rolled steel plate, galvanized steel plate, surface chemical treatment, coating (roll coating) or composite organic film (PVC film, etc.), and then baking and curing. Some people call this product "pre-rolled color steel plate" and "plastic color steel plate". Color plate products are produced in rolls by manufacturers on successive production lines, so they are also called color-coated steel coils. The color steel plate not only has the properties of high mechanical strength and easy forming of steel materials, but also has outstanding decoration and corrosion resistance of coating materials. Color steel plate is a new type of material respected in the world today. With the advancement of science and technology, the enhancement of environmental awareness, and the improvement of people’s living standards, color steel prefabricated houses have increasingly shown strong vitality and broad market prospects. The favorite of other industries.

 

The color steel movable house has the advantages of light weight, high strength, heat preservation and heat insulation, beautiful and durable, etc. It is an advanced repair and construction facility that integrates construction and decoration. The color steel plate movable house is clean in construction, and is widely used in large-span factories, warehouses, working buildings, villas, roof additions, air purification rooms, cold storage, shops, kiosks and temporary houses. Light color steel plate sandwich panels with a square meter weight of less than 14KG can fully reduce the structural load and reduce the structural cost of the mobile house.

 

1.2 Fast Folding Equipment

 

The color steel movable house has light weight, splicing equipment and free cutting characteristics, which determine the simplicity of its movable house equipment, which can greatly improve the efficiency and save the construction period. The surface quality materials and thermal insulation materials of the fireproof color steel plate sandwich panel are non-combustible materials, which can completely meet the fire protection requirements of the mobile room.

 

1.3 Folding durability

 

A variety of studies have shown that it has been widely used in foreign countries for more than 40 years to prove that the shelf life of color steel plates treated with special coatings is 10-15 years. In the future, anti-corrosion coatings will be sprayed every 10 years, and the life of movable house panels can reach more than 35 years.

 

Aesthetic The clear lines of the profiled color steel plate are as many as dozens of colors, which can meet the needs of any style of movable house building to achieve a satisfactory effect.

 

1.4 Folding thermal insulation

 

The commonly used thermal insulation materials of the color steel plate composite panel are: rock wool, glass fiber cotton, polystyrene (EPS), polyurethane, etc., with low thermal conductivity, and the mobile room has an excellent thermal insulation effect. High-strength color steel plate is made of high-strength steel plate (tensile strength 5600kg/cm) plus the most advanced design and roll forming. Therefore, the color steel plate movable house has excellent structural characteristics.

 

(2) Features of color steel plate

 

A.) The color steel plates can be disassembled and restored, which can be assembled and disassembled conveniently. The standard unit wall panels can be exchanged, which is very fast for the protection of water and electricity and line transformation.

 

B) The color steel plate can be arbitrarily opened, which is very convenient for equipment control switches, power sockets and other equipment, and no other treatment is required.

 

C) The color of the color steel plate is soft on the surface, and it forms a unified and harmonious whole with the floor and ceiling, making the entire space have a modern atmosphere.

 

D) The electrostatic paint spraying process is selected, the surface is smooth and delicate, does not accumulate dust, and is simple to maintain, which greatly ensures the cleanliness requirements of the machine room.

 

E) The color steel plate conforms to the national standard A-level fire protection standard, and can fully meet the fire protection requirements of the construction and decoration of the computer room.

 

(3) Equipment method of color steel plate

 

1) Stakeout: Stakeout (center line of partition wall) according to the drawing and actual measurement scale to pop out the center line of the ground rail at the intersection of the center line of the two sides and the ground. It should be ensured that these four lines are in a straight surface to ensure the straightness of the wall of the equipment in the future. 2) Sky rail: The equipment must be regular, the joints must be reinforced and repaired, and nails or screws are fixed to the cement ceiling every 500mm-600mm.

 

3) Ground rail: The equipment position of the door should be reserved first when the equipment ground rail, and the problem of ground difference should be paid attention to. If there is too much unevenness on the ground, it must be leveled to reduce the drop without affecting the level of adjustment. Fix the floor with hits or screws every 600mm. If the ground seam is too large, fill it with caulking agent.

 

4) Edge finishing: cut edges according to the actual measurement value, and trim the edges after cutting. Strive to be regular and common, and the joints are required to be seamless. Pay special attention to the interface with the sky and skirting board, and make sure that there is no gap.

 

5) Vertical keel: set a vertical keel every 49cm (half the size of the partition). The columns on both sides of the door frame are completely fixed up and down to prevent shaking. Add a vertical keel in the opposite direction, and the width of the door leaf exceeds 90cm. The horizontal column on the door frame must be strengthened and fixed, if necessary, be fixed by welding.

 

6) Horizontal piercing keel: Increase the height by more than 3 meters, and set one at 1.2 meters in a straight direction. When two branches are connected, it is necessary to overlap, and the overlap length shall not be less than 10cm.

 

7) Wall panel: Start the equipment from one side of the color steel plate, and the equipment in sequence, the distance between the connecting panels is 12mm. 12mm width bead is used between the partitions, and the standard unit wall panels can be exchanged.

 

(4) Equipment considerations

 

1) Use bead with a width of 12mm between the boards, and the standard unit wall boards can be exchanged. 3. Precautions for equipment color steel plates

 

2) Pay more attention to the details when using the equipment wall panel. First, transport the wall panel to the vicinity of the equipment point with a pallet truck, and then use the suction cup to stand the metal plate upright so that the lower end is against the skirting board, and both sides of the lining board are close to the vertical keel. , The distance between one side and the other wallboard is 12mm. Use the fixing piece to lie up, and then fix the self-tapping screw on the vertical keel. The fixing distance is between 300mm-400mm. When assembling, pay attention to the level and straightness. When the last piece is reached For wall panels, if it is necessary to cut, it is necessary to measure the dimensions and then trim them according to the correct method, and install them on the wall.

 

3) Use the "U"-shaped internal corner trimming strip to trim the corners of the wall to trim the internal corners.

 

4) Custom-made color steel plates customized by the factory can be used in the corners and pillars to achieve the overall effect and beauty.

 

5) In order to keep the corners and the wall in common, the corners of the wall should be finished with the same color professionally.
