Corrugated steel plate

Corrugated plate is also called profiled plate. It adopts color coated steel plate, galvanized sheet and other metal plates to be rolled and cold-formed into various corrugated profiled plates. It is suitable for industrial and civil buildings, warehouses, and special buildings. , The roof, wall and interior and exterior wall decoration of large-span steel structure houses. It has the characteristics of light weight, high strength, rich color, convenient and quick construction, earthquake resistance, fire resistance, rain resistance, long life, and maintenance-free. It has been widely promoted and applied.

product details

Features

1.Light weight: 10-14 kg/m2, equivalent to 1/30 of a brick wall.

2.Thermal conductivity: λ<=0.041w/mk.

3.High strength: It can be used as a load-bearing board for ceiling enclosure structure, resisting bending and compression; beams and columns are not used in general houses.

4.Bright color: no surface decoration is required, and the anti-corrosion layer of the color galvanized steel plate can be maintained for 10-15 years.

5.The installation is flexible and fast: the construction period can be shortened by more than 40%.

Dosage calculation formula

1. Two-sided sloping roof

Description of two-sided sloping roof

①The area of the roof: length×width.

②The total length of the required tile: roof area ÷ 0.855 (the effective width of the tile is 0.855M/piece).

③The number of tiles: (roof length÷0.855m)×2.

④The number of ridge tiles: roof length ÷ 2.4m (the effective length of ridge tiles is 2.4M/root).

⑤Number of sealing strips: (length ÷ 0.7m) × 2 (sealing strip 0.7M/piece).

⑥The quantity of the eaves cover: (length ÷ 0.7m) × 2 (the eaves cover 0.7M/piece).

⑦The number of special nails: 4PCS/㎡.

⑧The roof angle is less than or equal to 120 degrees.

2. Four-sided sloping roof

Description of sloping roof

①Budget roof area: (A+B+C+D)×117% (inclination and loss).

②The total length of the required tile: roof area ÷ 0.855 (the effective width of the tile is 0.855M/piece).

③The number of ridge tiles: (a×2+b+c×2) ÷ 0.7 (the effective length of ridge tiles is 2.4M/piece).

④Number of sealing strips: (length + width) ÷ 0.7 (sealing strip 0.7M/piece).

⑤The number of the eaves cover: (length + width) × 2÷0.7 (the eaves cover 0.7M/piece).

⑥The number of special nails: 4PCS/㎡.

Pre-installation engineering

Four-sided slope

1.The blue dashed line and the red dashed line are the horizontal and vertical skeletons respectively.

2.a The best distance is 50CM.

3.The distance of b is preferably 50-70CM.

Two sides slope

1.Choose the material of the frame, both wood structure and steel structure are suitable.

2.The construction surface needs to be tidied and leveled.

3.Frame material specifications: Wood specifications are 45MM×45MM or more, steel specifications are 40MM×40MM or more.

4.The longitudinal spacing of the frame should be kept between 50CM～70CM, and the horizontal spacing must be a multiple of 25CM, preferably not greater than 50M. Use screws as close as possible and weld firmly.

Installation work

The correct way of laying tiles

1.Overlapping type (applicable to roofs with length≦15M)

2.Staggered type (applicable to roofs 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 fixed interval of special nails is 50cm～100cm (preferably 4 pieces/㎡).

3.The special nails must be driven from the lower end of the tile toward the roof to have a beautiful, sealed and neat effect.

Install the sealing strip ridge tile cover

1.Separate the sealing strip in half, and place ridge tiles on the roof according to the tile type and fix them with special nails.

2.The joints of the side tiles are sealed with cement and then directly covered with ridge tiles, and the bottom of the ridge tiles is finished with a small tile stop.

3.The lower end of the tile, namely the eaves, is directly installed with the eaves cover and fixed with screws.

4.At the ridge tile junction, the contrast interface is trimmed with scissors and overlapped and sealed with glass glue.

Waterproof treatment of the protruding part

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

Connection installation on inclined surface

Refers to the construction where the two roof tiles are cut according to the angle and length, and the bottom is installed with water receiving treatment. First, install the water receiving material (ie gutter) under the tiles, and then use waterproof adhesive or cement for finishing.
