Comparison of aluminum alloy pv support and steel PV support

Many customers always hesitate to choose aluminum alloy photovoltaic bracket and steel photovoltaic bracket when choosing photovoltaic bracket.Today,I will make a comparison in strength,performance and price,hoping to help you:

1.Strength:As far as strength analysis is concerned,the strength of aluminum alloy is weaker than that of steel.Therefore,it is recommended to choose steel support to meet the strength requirement for photovoltaic support with high wind strength requirements or large span in practical application,while aluminum alloy photovoltaic support is mostly used in general areas.

2.Performance:Performance is also a relatively important parameter of photovoltaic bracket,because the advantages and disadvantages not only affect the service life of the power station,but also affect the appearance.Generally,the surface of the steel bracket is treated with hot zinc immersion,which is generally required to be above 65.Under normal conditions,it can have a service life of 20 years,but it needs regular maintenance.The surface of the aluminum alloy bracket is anodized to form a compact oxide film,which is far better than the steel bracket,and the surface aesthetics of aluminum alloy photovoltaic bracket is also better than the steel bracket.

3.Price:Compare the prices of the two.If the strength requirement is relatively high,aluminum alloy photovoltaic bracket can only be used to meet the requirements by increasing the material,and the price of aluminum alloy on the market is about 3 times that of steel bracket.And under the condition of the strength of the general requirements,such as photovoltaic stents,caigang watts usually span is small,so the strength requirement is not high,the selection of basic close to meet the strength of the aluminum alloy stent on the cost of steel bracket,and because the processing technology of the difference,the diversity of the cross section of the aluminum alloy stent can be made aluminum alloy stents form rich,installation is convenient.
