Product knowledge of corrugated steel plate

A corrugated steel plate is a kind of color-coated steel plate, which is rolled and cold-bent into various wave shapes. It is suitable for roof, wall, and internal and external wall decoration of industrial and civil buildings, warehouses, special buildings, and long-span steel structure houses. It has the characteristics of lightweight, high strength, rich color, convenient and fast construction, earthquake resistance, fire prevention, rain prevention, long service life, and maintenance-free, It has been widely used.

Category of corrugated steel plate:

  • Corrugated steel plate substrate is divided into the cold-rolled substrate, hot-dip galvanized substrate and electro-galvanized substrate.
  • The outer coating of the corrugated steel plate is divided into polyester, silicon calcium polyester, vinylidene fluoride, and plastic sol.
  • The finished state of the corrugated steel plate is divided into the coated board, embossed board, and printed board.
  • The commonly used corrugated steel plate is based on hot-dip galvanized steel plate and hot-dip aluminum galvanized steel plate. After being processed into the corrugated plate or polyurethane composite sandwich plate, it is used in steel structure plants, warehouses, frozen warehouses, airports, food, medicinal materials, and various commercial and civil buildings. It is also used for the shell of household appliances, automobile containers, and automobile interior trim parts for transportation.

Application characteristics of corrugated steel plate:

  1. The sandwich corrugated steel plate is installed quickly. The composite plate has the characteristics of light self-weight, splicing installation, and free-cutting, which determines its simple installation, which can greatly improve the efficiency and save the construction period.
  2. The weight of the sandwich corrugated steel plate is light, and the weight per square meter is less than 14kg, which can fully reduce the structural load and reduce the structural cost.
  3. It is durable. Various studies show that it has been widely used abroad for more than 40 years. It is confirmed that the shelf life of sandwich corrugated steel plate treated with the special coating is 10 ~ 15 years. After that, it is sprayed with an anti-corrosion coating every 10 years, and the service life of the plate can reach more than 35 years.
  4. It has fire prevention performance. The surface material and thermal insulation material of the color composite sandwich panel are noncombustible materials, which can fully meet the requirements of the fire prevention code.
  5. Beautiful appearance, clear lines of profiled steel plate can be up to dozens of colors, which can meet the needs of any style of architecture to achieve satisfactory results.
  6. Thermal insulation. The common thermal insulation materials of the composite board include polystyrene, rock wool, glass fiber wool, polyurethane, etc. these materials have low thermal conductivity. So it is widely used in modern architectural decoration.

Installation works:

Correct placement of tiles:

  1. Overlapping type (applicable to the roof with length ≤ 15m)
  2. Staggered type (applicable to the roof with length ≥ 15m)

Correct use of special nails:

  1. The special nail must be hit in the middle of the tile bone to have a waterproof effect.
  2. The fixing interval of special nails is 50cm ~ 100cm horizontally and vertically (preferably 4 pieces / ㎡).
  3. The special nail must be driven from the lower end of the tile to the roof to have a beautiful, sealed, and neat effect.

Install the weatherstrip ridge tile canopy:

  1. The special nail must be hit in the middle of the tile bone to have a waterproof effect.
  2. The fixing interval of special nails is 50cm ~ 100cm horizontally and vertically (preferably 4 pieces / ㎡).
  3. The special nail must be driven from the lower end of the tile to the roof to have a beautiful, sealed, and neat effect.

Waterproof treatment of protruding part:

First, make a V-shaped material. Different materials and specifications can be selected, depending on the actual situation. Make the water connection, install it at the bottom, and then lay color steel tiles on it.

Inclined plane connection installation:

It refers to the construction of installing water receiving treatment at the bottom after the two roof tiles are cut off according to the angle and length. First, install water receiving material (i.e. gutter) under the tiles, and then use waterproof adhesive or cement for finishing treatment.

Matters needing attention:

  1. Wear necessary safety facilities (such as gloves, helmet, safety belt, and other tools).
  2. Installation workers shall be professionals with certificates.
  3. The framework must be firmly installed.
  4. When walking on the tile during installation, try to step in the middle of the tile to avoid stepping on the edge of the tile.
  5. It shall be installed carefully in bad weather.
