The Hot dip Galvanized Solar Mounting Brackets provided by Shixinda are processed using the high-temperature hot-dip galvanizing process. The zinc layer thickness is uniform and meets the standards, and the corrosion resistance is excellent. The salt spray resistance is far superior to that of ordinary galvanized products. They can be adapted to complex and harsh working conditions such as coastal areas with high humidity and salt-alkali land. The brackets are paired with 8.8 grade hot-dip galvanized fasteners, and the overall anti-corrosion performance is unified, and the structure is stable and firm. Compared to aluminum alloy brackets, Shixinda's hot-dip galvanized photovoltaic brackets have extremely high cost performance. The ton price is only one-third of that of aluminum alloy, allowing for large-span installation and reducing the number of columns. The product is convenient to install and has strong durability, significantly reducing the construction and operation costs of the power station. With reliable quality and outstanding economic benefits, it is widely used in various photovoltaic engineering projects.
Strong Corrosion Resistance - Zinc layer thickness 55–85 μm, adhesion reaches 0 grade, corrosion resistance is 2–3 times that of cold galvanizing, suitable for various corrosive environments such as coastal, desert, industrial areas, etc.
Excellent Mechanical Performance - Made of Q235/Q355 materials, yield strength 235–355 MPa, Q355 bearing capacity is 30% higher than Q235, resistant to wind and snow, and earthquake, suitable for large spans and strong wind areas.
High Cost Performance - Ton price is only 4500–6000 yuan, approximately 1/3 of aluminum alloy, large-span design can reduce the number of columns, and the total life cycle cost is the best.
Long Service Life - Normal use for more than 25 years, high-end products last up to 30–50 years, synchronized with the lifespan of photovoltaic modules, maintenance-free.
Easy Installation - Standardized hole bolt connection, no need for on-site welding; multiple cross-section specifications (C41/C60/C80), length can be customized, construction efficiency is high.
Wide Applicable Scenarios - Strong weather resistance, suitable for all scenarios such as deserts, coasts, industrial areas, and agricultural greenhouses, resistant to ultraviolet rays, salt alkali, and temperature fluctuations.
1.Installation and Usage Specifications: During installation, strictly prohibit violent knocking, cutting, or sanding of the supports to avoid damaging the hot-dip galvanized protective layer. Use uniformly 8.8 grade hot-dip galvanized fasteners and prohibit the use of ordinary bolts to prevent electrochemical corrosion. Strictly follow the drawing standards for tightening torque to avoid missing installations or loose tightening, ensuring balanced overall force distribution and structural stability of the supports.
2.Daily Inspection and Maintenance: Regularly check for deformation of the support components, peeling of the coating, and loosening of bolts. Timely clean up accumulated dust, debris, and salt residue. Especially in coastal and saline-alkali conditions, the inspection frequency should be increased to reduce the erosion by corrosive substances.
3.Reparations and Prohibited Requirements: For damaged coating areas, use special zinc-rich coatings for timely repair to prevent the spread of rust. It is strictly prohibited to privately drill holes, weld, or modify the original structure of the supports. After strong winds, heavy rain, or heavy snow, special inspections of key stressed parts are required to ensure the long-term safe, stable, and durable operation of the photovoltaic supports.
How long is your delivery time? Depending on the quantity of the products, deliveries usually start in about 5 days.

Raw material inspection - Inspect the Q235/Q355 carbon structural steel coils for compliance with parameters such as yield strength, tensile strength, and thickness
Unloading and leveling - Unroll the steel coil using an unloading machine, and level it with a leveling machine to eliminate curling stress
Servo feeding + Punching - Precise feeding by servo motor, and online punching of bolt holes, installation holes, etc. with high hole position accuracy
Cold bending forming - Continuous rolling with multiple rollers to gradually bend the strip steel into C-shaped, U-shaped, etc. (such as C41, C60, C80 specifications)
Correction and straightening - Perform size correction and straightening on the formed profiles
Fixed-length cutting - Cut at the set length using hydraulic or flying saw, with a smooth cut edge
De-greasing and oil removal - Soak in a 50–60℃ alkaline degreasing agent for 10–15 minutes to remove rolling oil and dirt, with the standard being "water film does not rupture for 30 seconds"
Water washing (first time) - Rinse with clean water to remove residual degreasing agent
Acid washing and rust removal - Soak in 15% H₂SO₄ (with corrosion inhibitor) solution to dissolve surface oxide and rust until a silver-gray metal base is exposed
Water washing (second time) - Rinse with clean water to remove acid and impurities
Immersion in auxiliary coating agent - Immersion in a 15%–25% NH₄Cl + 2.5%–3.5% ZnCl₂ aqueous solution (at 55–65℃, for 5–10 minutes), forming a thin salt film on the surface to prevent rusting, enhance zinc immersion, and eliminate missed coating
Drying and heat treatment - Completely dry the workpiece surface moisture to prevent zinc splashing during hot-dip galvanizing
Hot-dip galvanizing - Immersion the workpiece in 440–460℃ molten zinc, with the zinc reacting with the iron base to form a double-layer anti-corrosion structure of zinc-iron alloy layer + pure zinc layer, with the zinc layer thickness reaching 55–85μm
Sorting - Remove excess zinc liquid, zinc nodules, and burrs from the surface
Cooling - Water cooling or air cooling to solidify and stabilize the zinc layer
Passivation treatment - Immersion in passivation solution to form a passivation film on the zinc layer surface, further improving corrosion resistance and reducing the formation of white rust
Rinsing + Drying - Rinse with clean water and dry after, completing the surface treatment
Quality inspection - Test zinc layer thickness (≥55μm), adhesion (grid test 0 grade), surface flatness, hole position accuracy, size tolerance, etc.
