Photovoltaic bracket accessories mainly include aluminum alloy beams, hot dip galvanized beams and so on. Bolts: including galvanized bolts, stainless steel bolts, etc., these bolts can firmly connect the photovoltaic bracket with the foundation to ensure its stability and reliability, and can support the roof and mechanism through expansion force in the case of accidental deformation or collapse. Support rods: mainly include steel pipe support rods, steel cable support rods, etc., which can provide additional support and stiffness for the photovoltaic support, making it more stable and reliable. Connectors: including galvanized connectors, stainless steel connectors, etc., these connectors can connect different types of photovoltaic brackets with the foundation to form an overall structure.
