Solar street light quotation

At present in view of the solar photovoltaic (pv) support the characteristics of simple structure, small volume, most in use steel is given priority to with light steel and small cross section of ordinary steel structural steel. Compared with hot rolled section steel, in the same area, under the condition of thin walled section radius of gyration can increase 50

at present in view of the solar photovoltaic (pv) support the characteristics of simple structure, small volume, most in use steel is given priority to with light steel and ordinary steel structural steel small section.

light structural steel, light steel mainly refers to the round steel, Angle steel and thin wall steel. With Angle steel used as a support member, the strength of the steel can be better used, and conducive to the overall bracket installation, but when used for bending and compression member of relatively large deformation.

at present, the national standard of the Angle relative to the solar stent optional model is not much, solar street light quotation so need more small Angle model to adapt to the current rapid development of solar street light market. Wall thickness of the thin-walled steel purlin artifacts, general use 1. 5 - 5 mm steel sheet, cold bending or cold rolling is made after all sorts of different cross section form and size of the thin-walled steel products.

compared with hot rolled section steel, in the same area, under the condition of thin walled section radius of gyration can increase 50 - 60%, cross section moment of inertia and resistance torque increase of 0. 5 - Three times, and thus can reasonable use of material strength,, but because of the thin wall steel processing is mostly in the factory, need high precision drilling to and photovoltaic panels after the screw holes.

the factory after processing drill buckle, solar street light quotation to hot-dip galvanized. Shipped to the site installation, because of the small section steel, tool is difficult to operation, the construction is difficult. At present domestic most of the panels installed, can not connect directly and thin-wall steel need other auxiliary fixed structure ( Such as press block, etc. ) 。 Recommended reading: what are the disadvantages of solar street light
