Material Selection for Solar Mounting Brackets
Selecting the correct material is essential for controlling structural performance, fabrication cost and corrosion resistance.
Q235B Carbon Steel
Q235B provides a cost-effective base material for fabricated steel brackets, base plates and secondary supporting members. It is suitable for applications where structural design requirements can be satisfied by the specified grade.
Typical components include steel mounting angles, connection plates and welded mounting assemblies.
Q355B High-Strength Structural Steel
Q355B offers higher specified strength than Q235B and can be considered for structural parts requiring increased load resistance or optimized section selection.
Its suitability must be checked against the required thickness, fabrication route, welding procedure and structural calculations.
S350GD / S420GD Coated Structural Steel
Continuously coated structural steel grades are suitable candidates for cold-formed mounting profiles when grade, formability, coating class and availability are matched to the project requirements.
Typical applications include roll-formed C/U channels and selected thin-walled mounting components.
Zinc-Aluminum-Magnesium Coated Steel
Zn-Al-Mg coated steel is an alternative for certain cold-formed mounting profiles where corrosion protection and forming performance are important.
The coating composition, coating mass, fabrication damage, cut-edge performance and environmental exposure should be evaluated before selection.
Corrosion Protection and Galvanizing Options
Photovoltaic mounting structures operate outdoors, often under combined effects of moisture, temperature cycling, pollutants and mechanical exposure. Corrosion protection therefore needs to be specified according to both the component manufacturing process and the project environment.
| Surface Protection | Applicable Reference | Characteristics | Selection Considerations |
| Post-Fabrication HDG | ISO 1461 / ASTM A123 | Zinc coating applied after fabrication | Suitable for eligible fabricated steel brackets and assemblies |
| Continuous Galvanized Steel | EN 10346 / ASTM A653 | Pre-coated sheet or strip used for cold forming | Check forming damage, cut edges and coating designation |
| Zn-Al-Mg Coated Steel | EN 10346 ZM or specified product standard | Continuously applied alloy coating | Check coating chemistry, mass and field exposure |
| Galvanized Hardware | ASTM A153 or specified fastener standard | Hot-dip galvanized hardware where applicable | Check fastener dimensions, fit and coating requirements |
Important Coating Selection Notes
Batch hot-dip galvanizing: Suitable fabricated steel articles may be galvanized after cutting, drilling, bending and welding. The coating is specified and inspected under the applicable galvanizing standard.
Pre-galvanized steel: Continuously galvanized strip is coated before it is cut and formed. Additional protection may be necessary at damaged regions or exposed cut edges, depending on the project specification.
Coating mass versus thickness: A designation such as Z275 represents a nominal coating-mass class, expressed in g/m² across both sheet surfaces under the applicable standard. It does not mean a 275 μm thick zinc coating.
Coating life: No fixed service-life guarantee can be inferred solely from a zinc coating designation. The expected performance depends on coating properties, atmospheric corrosivity, installation details, drainage, maintenance and the target design life.
ISO 1461 concerns batch hot-dip galvanizing of fabricated steel articles, while ASTM A653 covers continuously galvanized sheet products. The appropriate standard must follow the actual product and coating process.
Precision Manufacturing & OEM Fabrication
Cold Roll Forming
Production of C/U mounting channels from suitable steel strip with controlled cross-sectional geometry, profile consistency and specified cut lengths.
CNC Punching & Drilling
Custom round holes, elongated slots and connection patterns produced according to approved drawings and dimensional requirements.
Precision Cutting & Bending
Cutting, angle forming and plate bending to manufacture L-shaped brackets, base supports, adjustable plates and customized connection components.
Surface Protection
Batch galvanizing or pre-coated material routes can be selected according to fabrication sequence, coating specifications and component geometry.
Fabrication Quality Requirements
For engineered solar mounting components, the manufacturing process should control the following:
Cross-sectional geometry and dimensional tolerances.
Hole diameter, slot width, hole pitch and edge distance.
Bend radius, straightness and deformation.
Burr removal and edge condition.
Weld quality and coating restoration where required.
Coating continuity and surface appearance.
Assembly fit and fastener compatibility.
Pre-coated steel should not be welded without an appropriate procedure and subsequent corrosion-protection treatment for the affected area.
Structural Design & Engineering Considerations
Photovoltaic brackets are load-bearing structural components. Their selection must consider the complete load path, rather than only the thickness or nominal strength of the material.
Wind Load Resistance
Wind pressure and suction can produce bending, uplift, shear and connection forces. The design should consider array height, module inclination, local wind conditions, exposure, edge and corner effects, and structural configuration.
Snow and Dead Loads
Bracket design should account for photovoltaic module weight, self-weight of the mounting structure, snow loading and any other applicable imposed loads.
Connection and Anchoring Performance
Bolted connections, slotted holes, base plates, roof fixings and foundation anchors require verification for the forces transferred through the structure.
Deflection and Structural Stability
Member deflection, lateral stability, local buckling, connection slip and installation tolerances can affect long-term system performance.
Regional Design Standards
Applicable wind, snow and structural requirements may be based on regional regulations and standards, such as:
EN 1991 and relevant Eurocodes for European projects.
AS/NZS 1170 series for relevant Australian and New Zealand projects.
JIS C 8955 and other applicable provisions for Japanese projects.
Local structural and building codes for other destinations.
Engineering Boundary: Wind-speed and snow-load ratings must be established for a defined structure and project location. Individual photovoltaic brackets should not be marketed as having a universal load rating without supporting test data or structural calculations.
