1）轻型钢结构。轻型结构钢是一种十分轻便的材质，在安装时，如果采取的是角钢，那么可利用钢的强度进行支架安装，监狱角钢型号有限，采用小方钢安装能够解决这一问题。薄壁型钢也是轻型结构钢的一种，这种钢很薄，是通过冷弯或者冷轧制成的异型钢。这种钢材质虽然轻便，却无法直接与绝大多数电池板直接连接，因此需要利用铝压块、高强螺栓辅助固定，便于安装。

1) Lightweight steel structures. Lightweight structural steel is a very lightweight material. When installing, if angle steel is used, the strength of the steel can be used for bracket installation. The model of prison angle steel is limited, and using small square steel for installation can solve this problem. Thin walled steel is also a type of lightweight structural steel, which is very thin and is a special shaped steel made by cold bending or cold rolling. Although this type of steel is lightweight, it cannot be directly connected to the vast majority of battery panels, so it requires the use of aluminum compression blocks and high-strength bolts to assist in fixation and facilitate installation.

2）普通结构钢。普通结构钢的材料多为成本较低的碳素结构钢和低铝合金，截面种类和加工方式多种多样。太阳能光伏支架系统对于其截面有着固定要求。加工焊接型钢时，根据厚度的不同和要求，进行焊接加工。通过计算不同位置的受力情况，采用不同厚度的钢板，方便安装，大大节约材料。

2) Ordinary structural steel. The materials of ordinary structural steel are mostly low-cost carbon structural steel and low aluminum alloy, with a variety of cross-sectional types and processing methods. The solar photovoltaic bracket system has fixed requirements for its cross-section. When processing welded steel, welding processing is carried out according to the different thicknesses and requirements. By calculating the stress situation at different positions and using steel plates of different thicknesses, it is convenient to install and greatly saves materials.

太阳能支架对钢材性能的要求

Requirements for steel performance of solar brackets

太阳能支架对于钢性能要求很高。要求钢材具有强大的抗拉性，使结构更加可靠。另外就是钢材的屈服点，屈服点越高，截面就越小，越能节省材料和成本。具有良好塑性的钢材质，可以通过变形提醒结构被破坏，使人们及时发现和解决问题，提高钢材质塑性，有助于增强材质塑性，有助于增强整个结构的承载力。

Solar brackets require high steel performance. Require steel to have strong tensile strength to make the structure more reliable. Another factor is the yield point of steel. The higher the yield point, the smaller the cross-section, which can save materials and costs. A steel material with good plasticity can remind the structure of damage through deformation, enabling people to detect and solve problems in a timely manner, improving the plasticity of the steel, helping to enhance the plasticity of the material, and enhancing the bearing capacity of the entire structure.

对于钢材质而言，加工性能是否良好也关系到结构质量。具备良好加工性能的钢材质，可塑性很高，可以加工成结构所需要的各种零部件，而且这些零部件无一例外，其强度、塑性等性能颇佳。

For steel materials, the good processing performance also affects the structural quality. Steel materials with good processing performance have high plasticity and can be processed into various components required for structures, all of which have excellent strength, plasticity, and other properties.

支架的使用寿命关系到太阳能光伏系统的使用寿命，因此要求支架具有的耐用性和抗腐蚀性性能，牵一发而动全身，支架的好坏影响了整个结构，甚至对企业的经济效益造成严重的威胁。

The service life of the bracket is related to the service life of the solar photovoltaic system, so the durability and corrosion resistance performance of the bracket are required. The quality of the bracket affects the entire structure and even poses a serious threat to the economic benefits of the enterprise.
