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. Color steel tile is suitable for industrial and civil buildings, warehouses, special buildings, roof, wall, interior and exterior wall decoration of large-span steel structure houses, etc.
The color steel tile is light in weight, equivalent to 1 / 30 of the brick wall, with high strength. It can be used as ceiling enclosure structure. The plate is load-bearing, bending and compression resistant. The color of color steel tile is bright, without surface decoration. The anticorrosive coating of color galvanized steel sheet has a retention period of 10-15 years. The installation of color steel tile is flexible, and the construction period can be shortened by more than 40%.
The price of colored steel tile is not calculated by square area, but by length. The average price of colored steel tile is 16 yuan / m. For example, the weight of 4mm thick colored steel tile is 3.14kg per meter, and the price of this kind of colored steel tile is 5600 yuan per ton, which is about 17.58 yuan per meter.
The width of colored steel tile is generally about 1000 mm, and there are many types of length, about 750-1200 mm. The thickness ranges from 2-10 mm. The price of thin colored steel tile is cheap. The price of 2 mm colored steel tile is about 8 yuan per meter, and that of 10 mm colored steel tile is about 30 yuan per meter.
Laying methods of color steel tile: overlapping type (suitable for roof with length ≤ 15m); staggered type (suitable for roof with length ≥ 15m).
Fixation of color steel tile: special color steel tile nail shall be used for fixation. The special nail must be hit in the middle of the tile bone to have effect; the fixed interval of the special nail is 50-100 cm horizontally and vertically; the special nail must be hit from the lower end of the tile to the direction of the roof to have beautiful, sealed and neat effect.
Installation of sealing strip ridge tile eaves cover of color steel tile: divide the sealing strip into two parts, press it on the roof according to the tile type, cover the ridge tile and fix it with special nails. The joints of the side tiles are sealed with cement, and then the back tiles are directly covered, and the bottom of the back tiles are closed with small tiles. The lower end of the tile, that is, the eaves, is directly installed with the eaves cover and fixed with screws. At the junction of the back tile, the control joint is trimmed with scissors and overlapped after forming, and sealed with glass glue.
Inclined plane connection and installation of color steel tile: the inclined plane of color steel tile refers to the construction of water connection treatment at the bottom after the two roof tiles are cut according to the angle and length. First install the water receiving material (i.e. gutter) under the tile, and then finish with adhesive or cement.
