Quality requirement 1: For the steel used in the solar photovoltaic support industry, there should be no cracks, scars, folds, hemp patterns, bubbles and inclusions on the steel materials used, so that the normal use of the steel materials can be ensured.
Quality requirement 2: The surface of the steel used on the solar photovoltaic support must not have rust, pitting, scratches, and indentations, and its depth must not be greater than the thickness of the dry steel. The negative allowable deviation value needs to be half of the about.
Quality Requirement 3: There should be no defects such as delamination and slag inclusion at the edge or fracture of the steel used on the solar photovoltaic support, otherwise the service life of the equipment can be affected once it is used in the manufacture of the equipment.
Quality requirement 4: The corrosion level of the steel surface used on the solar photovoltaic support must be able to meet the standard, and must be able to meet the specified level C or higher. When the C level is used in the equipment manufacturing, the rust should be thoroughly derusted.
