1, small canopy
Such as: cantilever canopy, hanging canopy;
2. Large canopy
Such as a ceiling supported by a wall or column.
3, finalize the design canopy
Such as: new building materials, patented design, large-scale production in factories;
The canopy can also be divided into:
1, FRP canopy.
2. All-steel canopy.
3, PC board (sunshine board, endurance board) canopy.
material characteristics
The advantages and characteristics of the sun room * ceiling roofing material are described in detail: the spontaneous combustion temperature of the flame-retardant PC board is 630℃ (220℃ for wood), and the flammability of the PC board has reached GB(8624- 1997 flame-retardant B 1) by the National Fire-retardant Building Materials Quality Supervision and Testing Center, which belongs to the flame-retardant engineering material.
Chemical corrosion resistance? PC chemical corrosion resistant board has good chemical corrosion resistance, and can resist the corrosion of various organic acids, inorganic acids, weak acids, vegetable oils, neutral salt solutions, aliphatic hydrocarbons and alcohol at room temperature. Heat-resistant and cold-resistant PC durable board has good temperature difference resistance, which can adapt to all kinds of bad weather changes from severe cold to high temperature, and all physical performance indexes remain stable in the range of -40℃ to 120℃.
Photochemical PC resistor has the highest transmittance in visible light and near infrared spectrum. According to different colors, the light transmittance can reach 12%-88%.
