Product Description
Our steel structures for power and energy facilities are engineered for substations, electrical equipment supports, power plant buildings, and solar mounting platforms. Manufactured in China according to approved project drawings and applicable overseas standards, each steel component can be hot-dip galvanized for outdoor corrosion protection, then marked and packed for export.
We provide steel detailing based on overseas engineering drawings, precision fabrication, dimensional inspection, and material and galvanizing inspection reports to support project installation and acceptance.
- Outdoor Corrosion Protection: Hot-dip galvanizing helps protect steel structures in outdoor, coastal, and other corrosive environments.
- Precision Fabrication: Controlled manufacturing tolerances help ensure accurate positioning and installation of electrical equipment.
- Structural Reliability: Structural design can account for project-specific wind, seismic, and equipment loads in accordance with applicable codes.
- Project-Specific Detailing: Fabrication drawings and connection details can be developed based on approved engineering documents.
- Quality Documentation: Material certificates and applicable coating inspection reports are available to support project quality verification.

Our power and energy steel structures are manufactured according to approved project drawings, technical specifications, and applicable design codes. We support drawing review, steel detailing, connection design coordination, and fabrication drawing preparation to help ensure that structural components meet project requirements.
For substation gantries, electrical equipment supports, and solar platforms, key considerations include equipment loads, connection locations, installation clearances, wind loads, and site-specific environmental conditions. Where required, BIM detailing and coordinated shop drawings can help identify potential installation conflicts before fabrication begins.

Quality control is integrated into material verification, fabrication, dimensional inspection, and corrosion protection processes.
- Material Verification: Check steel grades, material certificates, and incoming material specifications.
- Dimensional Inspection: Verify member lengths, connection plates, bolt-hole positions, and critical installation dimensions against approved drawings.
- Welding Inspection: Perform visual inspection and applicable non-destructive testing according to project requirements.
- Hot-Dip Galvanizing Inspection: Check coating appearance, thickness, and other specified acceptance criteria.
- Pre-Shipment Inspection: Verify component markings, quantities, packing lists, and export packaging.
Material certificates, dimensional inspection records, galvanizing inspection reports, and other quality documents can be provided according to the project inspection plan and contractual requirements.

We specialize in steel structure fabrication for power infrastructure and industrial energy projects. Our product range includes substation gantries, electrical equipment support frames, power plant buildings, solar mounting platforms, and customized steel structures.
From drawing review and fabrication detailing to precision manufacturing, corrosion protection, and export packaging, we coordinate each stage according to approved project specifications. Quality control covers material verification, dimensional inspection, welding checks, and applicable surface treatment inspections.
For overseas customers, we can provide marked steel components, fabrication drawings, material certificates, and relevant inspection records according to project requirements. Our goal is to deliver reliable steel structure solutions that support efficient installation, long-term service, and the technical requirements of power and energy infrastructure projects.
