Single-column bracket
Also known as an "L" frame, a single-column bracket consists of a column perpendicular to the ground to hold the PV modules. This bracket is suitable for smaller PV power plant systems, and its simple structure and ease of installation make it a common type of bracket.
Double-column bracket
The double-column bracket, also known as the "T" bracket, consists of two uprights perpendicular to the ground and a crossbar. The double-column bracket is suitable for larger photovoltaic power plant systems, which are more stable in structure and can withstand greater wind force and weight.
Frame bracket
A frame bracket is a frame structure composed of multiple support rods and crossbars. It can be flexibly adjusted according to the size and number of PV modules, and is suitable for PV power station systems of various sizes.

Cheap: The cost of hot-dip galvanizing is lower than that of other coatings.
Reliable: The zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more
durable.
Strong toughness: The galvanized steel sheet layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
Comprehensive protection: Every part of the plated piece can be galvanized, and is fully protected even in depressions,sharp corners,and hidden places.
Save time and energy: Galvanizing process is faster than other coating methods.
