Color coated steel roofing is thin steel plate double-sided spraying, processing into a variety of corrugations to give the sheet good mechanical properties, acting as a roof tile. General color steel tile color to maintain 5-10 years, the service life of 10-15 years. Single-layer color steel tiles are generally used in factories and other places with low requirements for heat and sound insulation. For example, it can be used for steel structure building. And if it is used in residential office, generally use color steel sandwich plate to strengthen the effect of heat and sound insulation. Color steel plate has good mechanical properties, large span, convenient construction such as irregular opening, beautiful appearance, and slightly higher price. In addition, color steel plate can have different thickness, different surface coating treatment, which is directly related to the mechanical and anticorrosive durability of color steel plate. and other qualities, the price also has a big difference.
Color steel tile disadvantages.
1. No insulation does not insulate: color steel tile because there is no insulation layer, cold heat conduction coefficient is very fast, to the summer, indoor temperature is high, and to the In winter, the indoor temperature also drops fast with the climate change.
2.Dew phenomenon: especially in winter or sultry weather, when owners do not seal the doors and windows, the indoor air temperature is higher than the outdoor air. Temperature, color steel tile surface will appear on the small water droplets term condensation phenomenon. Easily cause color steel tile rust corrosion, shorten service life, will also bring inconvenience to the production.
3. The use of color steel tiles friends know that color steel tiles once used for a long time will produce bending deformation rust and other conditions.
Synthetic resin tile is the use of high-tech research and development of a new type of environmental protection and energy saving roof tile, noise and heat insulation, acid, alkali, corrosion resistance, light weight, and the use of synthetic resin tiles. Insulated, stable in size, easy to install, and never rusts. Due to its light weight, it can greatly reduce the load on the roof, reduce transportation costs and construction costs, for some of the old house addition and renovation of the Synthetic resin tiles are used in construction projects and new rural construction. Synthetic resin tiles have a color warranty of 10 years, a warranty of 20 years, and an actual service life of up to 30 years.
Disadvantages of synthetic resin tiles.
1. High temperature defects, we all know that synthetic resin tile is PVC and ASA as the main material of the co-extruded synthetic material, two materials All of them can be physically changed by their own vulcanization at about 180 degrees. After cooling molding the product will be deformed at 70-80 degrees Celsius due to high temperature. Therefore, synthetic resin roof tiles are not suitable for high-temperature areas such as smelting, casting, steel and other construction roof tiles.
2. Thermal expansion defect: When the temperature is between -30? and 70?, the intermolecular space structure of PVC will change due to the contrast between high and low temperature. Dramatic and obvious changes occur, i.e. thermal expansion and contraction. Therefore, the design of synthetic resin tile requires strict spacing of purlins to prevent the synthetic resin tile from sagging or bulging due to thermal expansion and contraction. Significantly reduces the waterproofing effect. (Treatment is fixed with double ear screws)
The synthetic resin tiles are antique glazed tiles, which tend to be beautiful and antique in design. The flat curved wave crest has a wave height of about 2.5cm which is not sufficient for the flowing water on the roof of a large span building, so it is recommended to have a large wave height. Synthetic resin roofing tiles should be used as the main roofing material for roofs with spans and flat slopes, but can be combined with high wave T-tiles. Add to match the use.
Which is more expensive, resin roofing or colored steel roofing?
In accordance with the price comparison between the two in the wholesale market, a comprehensive review: resin tile in the price is a little more expensive than the color steel tile, although resin tile is not dominant in price, but in the use of slightly better, whether it is antique aesthetics, or green rust, insulation, durability, etc. than the color steel tile!
Why Resin Tile is more durable than Color Steel Tile?
Because of the ease of installation of synthetic resin tiles are more common, it can be said that once installed, once and for all! However, after three or five years of color steel tiles will appear corrosion, rust, water leakage is likely to aging and cracking.
General color steel tile roofing life is short, during the repeated application of waterproof coating is very troublesome, and not insulated. Resin tiles generally have a service life of up to 30 years, widely used in the renovation of old houses, new villas, factories, farms, antique buildings. Farmhouse, landscaping and other construction roofing.
Comprehensive comparison down: resin tile in the weight and color steel tile compared to slightly heavier, but color steel tile corrosion-resistant problem has always existed, the price of Although resin tiles are slightly more expensive than color steel tiles, but the service life is at least twice as long as color steel tiles, heat insulation and sound insulation performance is more prominent. Therefore, compared to the performance of the various aspects of synthetic resin tiles slightly better. In fact, do not have to dwell on the resin tile and color steel tile which one is good, we all know that each product has its own advantages and disadvantages. Just choose the best tile for your use.
