Usage environment of photovoltaic mounting frames and steel requirements
The development of photovoltaic mounting frames for power generation requires higher efficiency, while also making the equipment easier to assemble and utilize.
In addition to using aluminum alloy, the equipment also requires high-quality steel. So, what are the quality requirements for these steels?
For steel used in the solar photovoltaic mounting frame industry, the material must be free from cracks, scars, folds, pits, bubbles, and inclusions to ensure normal use of the steel.
The steel used for solar photovoltaic mounting frames must not have rust, pitting, scratches, or indentations on its surface, and their depth must not exceed the thickness of the steel.
The edges or fractures of the steel used for solar photovoltaic mounting frames must not have delamination or slag inclusions. Otherwise, it may affect the service life of the equipment once used in manufacturing.
The corrosion grade of the steel surface used in solar photovoltaic mounting frames must meet national standards.
