color steel tile

Color steel tile, also known as color profiled tile, is a kind of profiled plate made of color coated steel plate and cold-formed by rolling.
It is suitable for industrial and civil buildings, warehouses, special buildings, large-span steel structure roof, wall and interior and exterior wall decoration. It has the characteristics of light weight, high strength, rich color, convenient construction, earthquake resistance, fire prevention, rain proof, long service life, maintenance free, etc., and has been widely applied.
characteristic
1. Light weight: 10-14 kg / m2, equivalent to 1 / 30 of brick wall.
2. Thermal conductivity: λ<= 0.041w/mk。
3. High strength: it can be used as ceiling enclosure structure plate for load bearing, bending and compression resistance; Generally, beams and columns are not used in houses.
4. Bright color: there is no need for surface decoration, and the anticorrosive coating of color galvanized steel sheet has a retention period of 10-15 years.
5. Flexible and fast installation: the construction period can be shortened by more than 40%.
⒍ oxygen index: (OI) 32.0 (provincial fire product quality inspection station).

Calculation formula of consumption
1、 Double slope roof
Description of double slope roof
1. Roof area: length × Width.
2. Total length of required tiles: roof area ÷ 855 M / sheet.
3. Number of tiles: (roof length) ÷ 0.855m） × 2。
4. Number of ridge tiles: roof length ÷ 4 m (effective length of ridge tile is 2.4 m / piece).
5. Number of sealing strips: (length) ÷ 0.7m） × 2 (sealing strip 0.7m / piece).
(3) number of canopies: (length) ÷ 0.7m） × 2 (0.7m / piece).
(3) quantity of special nails: 4pcs / m2.
8. The included angle of the roof is not more than 120 degrees.
2、 Four sides sloping roof
Description of four side slope roof
1. Estimated roof area: (a + B + C + D) × 117% (tilt and loss).
2. Total length of required tiles: roof area ÷ 855 M / sheet.
3. Number of back tiles: (a) × 2+b+c × 2） ÷ 7 (effective length of back tile is 2.4m / piece).
4. Number of sealing strips: (length + width) ÷ 7 (sealing strip 0.7m / piece).
5. Number of canopies: (length + width) × two ÷ 7 (0. 7m / piece).
(3) number of special nails: 4pcs / m2.
Pre installation works
Simian slope
1: The blue dotted line and the red dotted line are the horizontal and vertical skeletons respectively.
2: A the best distance is 50cm.
3: B the best distance is 50-70cm.
Double slope
1. Choose the material of skeleton, wood structure and steel structure are suitable.
2. The construction surface shall be leveled.
3. Specification of framework material: 45mm wood × Above 45mm, steel specification is 40mm × Above 40mm.
4. The longitudinal spacing of the framework should be kept between 50cm and 70cm, and the transverse spacing must be a multiple of 25cm, preferably not more than 50m. Screws should be used as close as possible and welded firmly[ 1]
Installation works
1、 The right way to lay tile
1. Overlapping type (suitable for roof with length ≤ 15m)
2. Staggered type (suitable for roof with length ≥ 15m)
2、 Proper use of special nails
1. The special nail must be hit in the middle of the tile bone to have waterproof effect.
2. The fixation interval of special nails should be 50cm-100cm (4 pieces / m2).
3. The special nails must be driven from the lower end of the tile to the direction of the roof in order to be beautiful, sealed and neat.
3、 Installation of sealing strip ridge tile eaves cover
1. Divide the sealing strip into two parts, press it on the roof according to the tile type, and fix it with special nails.
2. The joints of the side tiles shall be sealed with cement, and then the back tiles shall be directly covered, and the bottom of the back tiles shall be closed with small tiles.
3. The eaves cover is directly installed at the lower end of the tile, that is, the eaves, and fixed with screws.
4. At the junction of the back tile, the control joint shall be trimmed with scissors, and then overlapped and sealed with glass glue.
4、 Waterproof treatment of protruding part
First of all, 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 colored steel tiles on it.
5、 Installation of inclined plane connection
It refers to the construction of installing water connection treatment at the bottom of two roof tiles after they are cut according to the angle and length. First, install water connection 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, etc.).
2. Installation workers need professional personnel with certificate.
3. The framework must be firmly installed.
4. When the installation needs to walk on the tile, step on the middle part of the tile as far as possible to avoid stepping on the edge of the tile.
5. Careful installation in bad weather
