Dongmeng Group offers structural steel components and mounting assemblies for multiple photovoltaic installation methods. System selection depends on module arrangement, support conditions, foundation design, wind exposure, maintenance access and project requirements.

 

Ground-Mounted Solar PV Structures

 

Designed for open-field and large-scale solar applications. Configurations can incorporate driven steel piles, ground screws, or concrete foundations subject to geotechnical and structural design. Steel posts, rafters, C/Z purlins and diagonal bracing form a load path from the modules to the foundation.

Commercial & Industrial Rooftop Mounting

 

Customized supports for suitable metal or concrete roofs, with mechanical attachment or engineered ballast arrangements where appropriate. Roof capacity, uplift resistance, waterproofing, thermal movement and compatibility with roofing materials must be checked.

Solar Carport Mounting Structures

 

Structural steel columns, beams, purlins and connection plates for solar parking canopies. Designs are coordinated with vehicle clearance, column spacing, wind uplift, drainage arrangements and applicable building requirements.

Agricultural PV Support Structures

 

Elevated galvanized steel framing for agrivoltaic installations. The structure can be configured for agricultural machinery access, crop clearance, module spacing and site-specific foundation requirements.

The following specification guide summarizes the main configurable parameters for galvanized steel solar mounting structures. Final values are determined by the approved drawings, manufacturing feasibility, structural requirements and agreed purchase specification.

The performance of a solar mounting structure depends not only on the base material but also on its cross-sectional geometry, connection details, corrosion protection and installation tolerances.

 

C Channels & C Purlins

Cold-formed steel profiles used as secondary support members, purlins or mounting rails. Section depth, flange width, lip geometry, thickness and punching pattern are selected for the structural application.

Z Purlins

Z-shaped steel profiles for suitable continuous-span or lapped structural arrangements. Lapping and connection details must be designed to provide the intended load transfer.

Posts & Structural Tubes

Round, square and rectangular hollow sections, together with selected open profiles, used in vertical supports and bracing. Member sizes depend on axial loading, bending, buckling and foundation connections.

Brackets, Base Plates & Connections

Custom-fabricated connectors including gusset plates, slotted brackets, anchoring plates and splice components. Hole position, edge distances, bolt access and coating compatibility are controlled through the approved fabrication drawing.

A properly selected steel profile must resist the forces introduced by the PV modules, including bending, shear, axial compression or tension, and possible torsion.

For slender cold-formed C and Z profiles, local buckling, distortional buckling, connection eccentricity and effective section properties can govern the design. Simply increasing the profile thickness without checking these factors does not necessarily produce the most efficient solution.

Dongmeng Group can support project procurement with customized dimensions and fabricated components based on defined design criteria.

Galvanized steel mounting structures are exposed to outdoor environments for extended periods. The choice of coating process is therefore a critical purchasing decision, particularly in coastal, humid, industrial and high-salinity locations.

Hot-Dip Galvanized vs Pre-Galvanized vs Zn-Al-Mg Coated Steel

Important engineering distinction: ISO 1461 and ASTM A123 apply to relevant batch hot-dip galvanized products, while EN 10346 and ASTM A653 cover continuously coated flat steel products. They should not be presented as interchangeable certifications for every galvanized component. Fasteners may require separate coating specifications.

For PV mounting structures, coating selection should consider environmental corrosivity, condensation, chloride exposure, surface drainage, crevices, dissimilar-metal contact and accessibility for future inspection.

A 25-year or longer project design life does not automatically mean that any specific galvanized coating is maintenance-free for that period. Coating life depends on local environmental conditions, initial coating characteristics and protective design. ISO 14713-1 provides guidance on zinc coating selection and corrosion resistance in different environments.

For project inquiries, please specify the required coating standard, coating thickness or mass, location and expected environmental exposure.

Designed Around the Actual Project Conditions

Reliable solar mounting systems require verification of the complete structural load path, from the PV module and clamping system through the support members and connections to the building structure or foundation.

The following factors should be assessed during system selection:

Wind pressure and uplift, including edge and corner effects

Ground or roof snow actions, drifting and accumulation where applicable

Permanent loads from modules, rails, cables and ancillary equipment

Seismic effects when required by local regulations

Member strength, buckling, serviceability and connection capacity

Foundation resistance, soil characteristics and settlement

Thermal movements, differential expansion and installation tolerances

Design loading may reference ASCE/SEI 7, EN 1991, AS/NZS 1170, or another applicable national code. Steel member design, anchorage and building approvals must follow the relevant project jurisdiction. ASCE 7-22, for example, covers load types including wind, snow and seismic actions.

Wind Load and Snow Load Verification

Wind and snow resistance must be evaluated for the actual panel layout, inclination, height, terrain, exposure and support geometry.

Published generic values such as a maximum wind speed or a uniform bracket capacity are not sufficient to confirm project safety.

Before production approval, the responsible project engineer should verify member sizes, bracing, connection strength, foundations and required serviceability limits.

Foundation and Attachment Compatibility

Ground-mounted systems: Foundation options may include driven steel piles, screw piles and reinforced concrete foundations. The appropriate solution depends on soil conditions, corrosion exposure, installation constraints and verified geotechnical parameters.

Rooftop systems: The existing roof structure, roof sheet or substrate, approved anchors, attachment spacing, uplift loads and waterproofing details must be assessed before installation.

Dongmeng Group supports OEM and project-specific sourcing for galvanized steel mounting members and fabricated assemblies.

Q1. What is included in a galvanized steel PV mounting system?

A galvanized steel PV mounting system may include support posts, rafters, purlins, rails, bracing, connection plates, mounting brackets and compatible fasteners. The exact scope depends on the agreed bill of materials. PV modules, electrical equipment, foundations and installation services are not automatically included.

Q2. Which steel grades are commonly used for solar mounting structures?

Q235B and Q355B are common material options for fabricated steel support members. European structural grades or coated structural steel grades may also be specified. The final material selection must reflect the structural design, manufacturing route and applicable standards.

Q3. Can you supply custom C and Z channel profiles?

Yes. Custom C and Z profiles can be evaluated based on the required dimensions, thickness, hole patterns, lengths and steel grades. Buyers should provide section drawings and tolerance requirements for technical review.

Q4. What is the difference between hot-dip galvanized and pre-galvanized PV structures?

Post-fabrication hot-dip galvanizing applies a zinc coating to the fabricated steel member after suitable preparation. Pre-galvanized profiles are generally formed from already-coated steel strip. The methods differ in coating coverage, applicable standards and the treatment required for cut or punched surfaces.

Q5. What galvanized coating thickness should I specify?

Coating requirements should follow the selected coating standard and project exposure conditions. Post-fabrication HDG is generally specified by coating thickness, while continuously coated steel is commonly specified by coating mass or coating designation. A target such as 80 μm must be evaluated against the applicable material, process and project requirements.

Q6. Can your PV mounting systems withstand high wind and snow loads?

The mounting structures can be specified for project-defined loading requirements. Actual capacity must be established through structural calculations considering module layout, supporting members, connections, foundations and applicable design codes. A single general wind or snow resistance figure does not apply to all configurations.

Q7. Are galvanized steel solar mounting structures suitable for coastal areas?

They can be used in coastal projects when the corrosion protection system is suitable for the exposure conditions. Buyers should provide the installation location and relevant corrosion requirements so that coating selection, fastener compatibility and maintenance considerations can be evaluated.

Q8. What foundations can be used for ground-mounted solar structures?

Potential options include driven steel piles, screw piles and concrete foundations. Their suitability depends on soil conditions, structural loads, corrosion risk and installation requirements. Foundation selection must be verified by the responsible engineer.

Q9. Are the mounting structures compatible with different solar panel sizes?

Compatibility is evaluated against the module dimensions, frame characteristics, designated clamping zones, installation orientation and support spacing. The module datasheet and approved mounting instructions are necessary to confirm the configuration.

Q10. Can you manufacture according to our drawings?

Dongmeng Group supports project-specific fabrication inquiries based on technical drawings, bills of materials and agreed specifications. Custom dimensions, punching patterns, fabrication details and coating requirements can be evaluated before quotation and production approval.

Q11. Can you provide material test certificates and inspection reports?

Material certificates, including EN 10204 3.1 where applicable, and agreed inspection reports may be requested as part of the order documentation. Third-party inspection can also be coordinated where specified. The exact document package should be confirmed before ordering.

Q12. What is the expected service life of a galvanized PV mounting structure?

Service life depends on the steel design, environmental exposure, coating system, installation quality and maintenance conditions. Projects targeting 25 years or longer should establish appropriate durability requirements and verify the selected corrosion protection strategy rather than relying on a general lifespan claim.

Q13. Can you supply mounting structures for solar carports and agricultural projects?

Yes, custom structural steel components for solar carports and agricultural PV installations can be reviewed against project drawings. Requirements such as vehicle or machinery clearance, foundation arrangement and applicable loading must be defined.

Q14. What information is needed for an accurate quotation?

Please provide the project location, mounting type, approximate project capacity, PV module details, structural drawings or bill of materials, required steel grade, coating specification, quantity, delivery destination and any mandatory testing or documentation.

Q15. What are the MOQ and delivery lead time?

Minimum order quantity and lead time depend on the product dimensions, tooling needs, material availability, fabrication complexity, coating process and order quantity. Commercial terms are confirmed after technical review.
