The concrete bracket is mainly used in the large-scale photovoltaic power station, because of its self significant, can only be placed in the field, and the foundation is better region, Solar mounting racks but the stability is high, can support the large size of the battery board.
The steel bracket has stable performance, mature manufacturing process, Solar mounting racks high bearing capacity, simple installation, excellent anti-corrosion performance, Solar mounting racks beautiful and unique connection design, easy installation and quick installation tools, simple general use of structural anti-corrosion materials steel and stainless steel parts, service life of more than 20 years.
Aluminum alloy bracket is generally used in the building roof solar energy application, aluminum alloy has corrosion resistance, light quality, beautiful and durable characteristics, Solar mounting racks but its low bearing capacity, can not be used in solar power plant projects.
The installation structure of the PV array bracket should be simple and durable. Materials for the installation of photovoltaic arrays should be able to withstand rain erosion and various corrosion. Electroplating aluminum profiles, electroplating steel and stainless steel are ideal choice. Solar mounting racks The quality requirements for the welding of the bracket should conform to the requirements of the national standard of "steel structure construction Quality Acceptance Code" (GB50205-2001).
1, in the Photovoltaic Array Foundation and stent construction process, Solar mounting racks should try to avoid the related buildings and ancillary facilities damage, such as due to the construction needs to cause local damage, should be repaired in a timely manner after the completion of construction.
2. When installing photovoltaic arrays on the roof, Solar mounting racks to make the base embedded parts and the roof main structure of the steel bar firmly welded or connected, if the structural constraints can not be welded or connected, should take measures to increase the base and roof adhesion, and the use of wire tension or stent extension fixed method, etc. to be fixed. After the completion of the base, Solar mounting racks to the roof damage or involved in part according to the National standard "roofing Engineering Quality Acceptance Code" ($literal) of the requirements of waterproof treatment, to prevent water seepage, leakage phenomenon occurs.
