Our solar panel brackets (also called PV brackets, solar mounting brackets, or photovoltaic support systems) are designed for residential, commercial, and utility-scale solar installations. We offer high-strength, corrosion-resistant brackets in three materials: hot-dip galvanized steel pipes, aluminum alloys, and stainless steel (304/316), suitable for roof-mounted, ground-mounted, and adjustable-angle solar systems.
Manufactured according to international standards (ASTM, EN, JIS), these solar brackets ensure long-term durability, load stability, and compatibility with all major PV module types. Whether you require lightweight aluminum, heavy-duty galvanized steel, or premium stainless steel, our brackets deliver reliable performance under harsh weather conditions.Solar mounting structures are critical infrastructure for installing photovoltaic modules. Their primary function is to securely fix and support PV modules while adjusting their tilt angles and orientation to maximize sunlight exposure. Solar mounting systems can be categorized in various ways, and below are the classifications of PV mounting structures.

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.
Product Details
Galvanized square pipe is a kind of square section steel pipe treated by hot-dip galvanizing process, which has excellent anti-corrosion performance and structural strength. It is widely used in building structure, machinery manufacturing, municipal engineering and other fields.
▸ Material: Q235B/Q355B carbon steel (optional)
▸ Specification range: 20×20mm~150×150mm (wall thickness 1.0-6.0mm)
▸ Zinc plating layer: national standard zinc layer (average ≥ 80μm) / thickened zinc layer (120-275μm) optional
▸ Executive standard: GB/T 3091-2015, ASTM A53
▸ Anti-corrosion grade: 15-20 years for outdoor service life
Anticorrosive: 13 years in heavy industrial areas, 50 years in the ocean, 104 years in the suburbs and 30 years in cities.
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.
