What are the roof panels? Classification description and comparison recommendation

There are many roof panels. How to choose the corresponding ones? Today, we recommend several representative types of roof tiles on the market, including common daylighting tiles, color steel tiles and plastic steel tiles. What are their characteristics, advantages and disadvantages? According to the classification of small series, daylighting tiles are not easy to burn, have excellent corrosion resistance, heat and cold resistance, and have light impact resistance, and are easy to handle and install, But on the other hand, the bearing capacity of the product may be slightly inferior. Interested consumers can learn from the following. What we want to show you is the comparison and analysis between various roof panels.
1、 Advantages and characteristics of daylighting tile:
1. Flammability
The self-ignition temperature of the daylighting tile is 630 ℃ (the wood is 220 ℃), and the flammability of the board reaches GB (8624-1997, Class B1) according to the test of the National Center for Quality Supervision and Testing of Fireproof Building Materials, which is a fire-retardant engineering material.
2. Chemical corrosion resistance
The daylighting tile has good chemical corrosion resistance and can resist the erosion of various organic acids, inorganic acids, weak acids, vegetable oils, neutral salt solutions, aliphatic hydrocarbons and alcohol at room temperature.
3. Heat and cold resistance
The daylighting tile has good temperature resistance, can adapt to all kinds of adverse weather changes from severe cold to high temperature, and maintain various physical performance indicators stable within the range of - 40 ℃ to 120 ℃.
4. Photochemistry
The daylighting tile has the highest transmittance in the visible and near-infrared spectrum. Depending on the color, the light transmittance can reach 12% - 88%. 5. UV resistant, anti-aging
The surface of the daylighting tile contains an anti-ultraviolet co-extrusion layer, which has good outdoor weather resistance, and maintains good optical and mechanical properties after long-term use.
6. Impact resistance
The impact strength of the daylighting tile is 80 times that of the glass, and the solid plate is 200 times that of the glass, which can prevent breakage during transportation, installation and use; In addition, the most prominent feature of the solar panel is that it will not break like the common glass, so as to avoid injury to people and greatly guarantee safety.
7. Light weight of lighting tile
It is 1/12-1/15 of the same glass, safe and unbreakable, easy to handle and install, can reduce the dead weight of the building, simplify the structural design, and save installation costs.
2、 Features of color steel tile
1. Diversified specifications
Such as enterprise type, H-type, corrugated type, etc., with bright color and no need for surface decoration
2. Flexible and convenient installation
The composite plate not only greatly reduces the cost of the foundation engineering and structural engineering of the building, but also can be disassembled and disassembled many times. The construction and installation are flexible and convenient, and the comprehensive benefits are very significant.
3. Good fire resistance
The core material is a Class B1 refractory material with an oxygen index ≥ 26. It will not melt during combustion, and has no black smoke and no high-temperature decomposition droppings. It is currently a high-grade fireproof building decorative composite plate in China, and is the preferred decorative plate for GMP plants.
4. Wide temperature range
The operating temperature of the core material is - 70 ℃ - 120 ℃, reaching 200 ℃ instantaneously. When used in low or even ultra-low temperature environment, the shrinkage is small, and it is not brittle. It is an ideal thermal insulation material for cryogenic (cold storage) engineering.
5. Non-toxic and tasteless
The core material does not use Freon foaming agent. It is non-toxic and odorless when burning. The overflowing gas is harmless to the human body and the environment. It meets the national environmental protection requirements and is a new type of green building material.
7. Waterproof and moisture proof
The core material is an organic polymer foaming material with a closed cell structure and good water absorption resistance and water vapor permeability resistance.
