Product description

Highlights at a glance

  • *Hot Dip Galvanized Anti-Corrosion Finish: Full-immersion HDG to ISO 1461 delivers uniform 60-85 micron zinc coating, verified per batch with digital thickness gauge. Outlasts painted frames 5:1 under UV, rain, and salt spray. Eliminates on-site repainting entirely, reducing 25-year lifecycle maintenance cost to near zero for your solar farm investment.
  • *OEM Custom Steel Fabrication: We weld to your exact drawings in Q235, Q345, or Q355 carbon steel · from 50kg string inverter brackets to 5T+ utility-scale containerized chassis. Every frame undergoes CNC laser or flame cutting, full-penetration MIG welding, and post-weld dimensional inspection. MOQ starts at 10 units, with free engineering DFM review before production.
  • *Heavy-Duty Welded Structural Integrity: Base plates up to 20mm thick with gusset reinforcement at all load-transfer points; straightness held within 2mm per meter. 100% visual weld inspection eliminates cold laps, undercut, and porosity. Engineered for 500kg to 5,000kg static loads with zero deflection under seismic and high-wind conditions.
  • *Versatile Single-Source Portfolio: One manufacturer covers skid bases, pedestal frames, C-channel foundations, anchor base plates, ground-mount plinths, and modular chassis assemblies. Pre-engineered bolt patterns compatible with Huawei, Sungrow, SMA, and ABB inverters. We match your existing civil foundation anchor layout or propose optimized spacing to reduce site rework.
  • *Factory-Direct Supply Chain Edge: 15-25 day lead time from a 20,000sqm facility backed by 3 in-house hot dip galvanizing lines. ISO 9001 certified QC · every shipment includes material mill certificates, weld inspection reports, and zinc thickness test data. Free sample for qualified first-time buyers. FOB Shanghai, container loading optimized for your import logistics.
  • Frequently asked questions

    Yes. Our engineering team can design the complete base including structural analysis, mounting layout, lifting provisions, and vibration control from your equipment specifications alone. We provide 3D models and FEA reports for your approval.

    No problem. We match your exact bolt pattern. CNC drilling ensures precision positioning. Simply send us your equipment GA drawing or bolt layout table.

    Yes. We can provide static structural FEA reports showing stress distribution, deflection, and safety factors under your specified load conditions. Dynamic / modal analysis also available for vibration-sensitive equipment.

    Yes. We work with SS304, SS316, SS316L, and duplex stainless steel (2205) for chemical plants, offshore platforms, food-grade applications, and marine environments. Separate tooling and work areas prevent carbon steel contamination.

    We can fabricate bases up to 12m * 4m in a single piece in our workshop. Larger structures can be designed as bolted modular sections for transport. We handle break-bulk, flat-rack, and open-top container shipping.

    We use controlled welding sequences, pre-set distortion allowance, temporary bracing, and post-weld straightening (flame or mechanical) as needed. Critical mounting surfaces are CNC machined AFTER welding and stress relief to ensure flatness.

    We accept single-piece trial orders for new customers. For production runs, MOQ is flexible and discussed case by case. We value long term partnerships over minimum quantity requirements.

    Typical lead time is 25 to 40 days after drawing approval and deposit receipt. Urgent orders can be expedited with an agreed timeline. We provide a production schedule with milestone dates after order confirmation.
