Can galvanizing be used for 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.

Which material should be used for photovoltaic (PV) support structures?

When it comes to selecting the material for photovoltaic (PV) support structures, it generally adopts Q235B steel and aluminum alloy extrusion profile AL6005-T5. Each material has its advantages and considerations, and the choice depends on various factors. Let’s compare steel and aluminum for PV support structures:

What is the best material for a PV bracket?

This characteristic makes aluminum a suitable choice for PV installations in coastal areas or locations with high humidity. At present, the main anti-corrosion method of the bracket is hot-dip galvanized steel with a thickness of 55-80 μm, and aluminum alloy with anodic oxidation with a thickness of 5-10 μm.

How do I choose a steel or aluminum PV support structure?

Ultimately, the selection of steel or aluminum for PV support structures depends on project-specific factors such as the size of the installation, load requirements, budget, site conditions (e.g., wind and snow loads, corrosive environments), and sustainability goals.

Why is halogen galvanizing difficult?

The corrosion rate of halogen to steel is very fast, and within one year may cause the weakening of the overall support structure, causing safety hazards. Therefore, it is not easy to achieve a highly uniform galvanizing process. Secondly, the connection of section steel and steel is a technical difficulty.
