Quality requirements for galvanized photovoltaic brackets

JG/T 490-2016 English PDF. This standard specifies the classification and marking, general requirements, requirements, test methods, inspection rules, marking, packaging transport and storage of solar photovoltaic system supports. This standard applies to buildings, structures and ancillary venues installed solar photovoltaic system with support.

The following is an example of an assembled steel bracket. First, high-quality section steel usually has a high-level galvanizing process. According to the requirements of national standards, the average thickness of the galvanized layer should be greater than 50μm, and the minimum thickness should be greater than 45μm.

The appearance quality of the profile conforms to the regulations in GB5237.2-2004. The surface of the profile should be clean and smooth, and serious defects such as cracks, peeling, corrosion and air bubbles are not allowed. When choosing solar photovoltaic brackets, you can see products made of different materials. The brackets made of .

A: The selection of PV brackets depends on factors such as the type of solar panel, the mounting location (rooftop, ground, etc.), the local climate, the desired tilt angle, and the load-bearing capacity of the mounting surface. It is also important to consider local building codes and standards.

Material Quality: Choose high quality materials such as aluminum or galvanized steel that are resistant to corrosion and can withstand harsh weather conditions. 3. Installation Flexibility: Select a structure that offers flexibility in installation, allowing for easy adjustment and alignment of the panels to maximize sunlight exposure.

5 FAQs about [Quality requirements for galvanized photovoltaic brackets]

What is solar photovoltaic bracket?

Solar photovoltaic bracket is a special bracket designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. The general materials are aluminum alloy, carbon steel and stainless steel. The related products of the solar support system are made of carbon steel and stainless steel.

What types of solar photovoltaic brackets are used in China?

At present, the solar photovoltaic brackets commonly used in China are divided into three types: concrete brackets, steel brackets and aluminum alloy brackets. Concrete supports are mainly used in large-scale photovoltaic power stations. Because of their self-weight, they can only be placed in the field and in areas with good foundations.

What is an example of an assembled steel bracket?

What are the technical difficulties in assembling section steel brackets?

In short, there are many technical difficulties in the production process of the assembled section steel bracket, which requires metallurgical engineering and technical personnel to overcome technical barriers and further reduce its use cost.

What makes a good bracket system?

(6) The cost should be reasonable. A high-quality bracket system must use computer simulation software for extreme weather conditions to verify its design, and conduct strict mechanical performance tests, such as tensile strength and yield strength, to ensure the durability of the product.
