⒈Light weight: 10-14 kg/m2, equivalent to 1/30 of a brick wall.

⒉ Thermal conductivity: λ<=0.041w/mk.

⒊High 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.

⒋Bright color: no surface decoration is required, and the anticorrosive layer of the color galvanized steel plate can be kept for 10-15 years.

⒌ Flexible and quick installation: the construction period can be shortened by more than 40%.

⒍Oxygen Index: (OI) 32.0 (provincial fire product quality inspection station).


Dosage calculation formula

1. Two-sided sloping roof

Description of two-sided sloping roof

⒈)The area of the roof: length×width.

⒉)The total length of the required tile: roof area ÷ 0.855 (the effective width of the tile is 0.855M/piece).

⒊)The number of tiles: (roof length÷0.855m)×2.

⒋)The number of ridge tiles: roof length ÷ 2.4m (the effective length of ridge tiles is 2.4M/root).

⒌)Number of sealing strips: (length ÷ 0.7m) × 2 (sealing strip 0.7M/piece).

⒍)The quantity of the eaves cover: (length ÷ 0.7m) × 2 (the eaves cover 0.7M/piece).

⒎)The number of special nails: 4PCS/㎡.

⒏)The roof angle is less than or equal to 120 degrees.

2. Four-sided sloping roof

Description of sloping roof

⒈)Budget roof area: (A+B+C+D)×117% (inclination and loss).

⒉)The total length of the required tile: roof area ÷ 0.855 (the effective width of the tile is 0.855M/piece).

⒊)The number of ridge tiles: (a×2+b+c×2) ÷ 0.7 (the effective length of ridge tiles is 2.4M/piece).

⒋)Number of sealing strips: (length + width) ÷ 0.7 (sealing strip 0.7M/piece).

⒌)The number of the eaves cover: (length + width) × 2÷0.7 (the eaves cover 0.7M/piece).

⒍)The 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

⒈)Choose the material of the frame, both wood structure and steel structure are suitable.

⒉)The construction surface needs to be tidied and leveled.

⒊)Frame material specifications: Wood specifications are 45MM×45MM or more, steel specifications are 40MM×40MM or more.

4 )The longitudinal spacing of the framework 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

1. The correct way of laying tiles

⒈)Overlapping type (applicable to roofs with length≦15M)

⒉)Staggered type (suitable for roofs with length ≧15M)

2. Correct use of special nails

⒈)The special nail must be hit in the middle of the tile bone to have a waterproof effect.

⒉)The fixed interval of special nails is 50cm~100cm (preferably 4 pieces/㎡).

⒊)The special nails must be driven from the lower end of the tile toward the roof to have a beautiful, sealed and neat effect.

3. Install the sealing strip ridge tile cover

⒈) Separate the sealing strip in two halves, press the ridge tile on the roof according to the tile type, and fix it with special nails.

⒉)The junction of the side tiles is sealed with cement and then directly covered with ridge tiles, and the bottom of the ridge tiles is finished with a small tile stop.

⒊)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.

4 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 the water connection is installed at the bottom, the color steel tiles are laid on the top.

5. 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.


1. Wear the necessary safety equipment (such as gloves, helmets, safety belts and other tools).

2. The installation worker needs to be a professional with a certificate.

3. The skeleton must be firm when installed.

4. When installing and walking on the tiles, try to step on the middle part of the tiles to avoid stepping on the edges of the tiles.

5. Be careful to install in bad weather.
