Product description

Highlights at a glance

  • *OEM Custom Welded Multi-Industry Support Frames: One factory delivers pressure vessel saddles, chemical mixer bases, HVAC mounting platforms, transformer support structures, and electrical equipment skids · all fabricated from your engineering drawings. Storage vessel, chemical processing, food production, industrial ventilation, and power distribution sectors covered.
  • *Certified Engineering for Pressure Vessel and Electrical Applications: ASME-compliant saddle design for horizontal tanks and pressure vessels. Rigid welded bases for transformers, switchgear, and UPS cabinets with precision mounting holes. AWS D1.1 qualified welding and ISO 9001 QC with BV and CE certification reports included.
  • *Application-Matched Surface Protection Systems: Hot dip galvanizing for outdoor cooling towers and transformer bases, chemical resistant coating for dust collector and fume exhaust environments, epoxy anti-corrosion for chemical mixer platforms, 3-layer coating for storage tank foundations, and powder coating for indoor electrical panels and switchgear.
  • *Hybrid Material Solutions for Cost-Effective Compliance: Carbon steel (Q235/Q345/Q355/S355JR/S355J2/ASTM A36) for structural frames, with 304 stainless steel contact parts available for food-grade mixing tank foundations · meeting hygiene requirements without the full cost of an all-stainless base.
  • *Vibration-Dampening and Load-Distributed Design: Heavy steel plate construction with reinforced gussets for rotating equipment · centrifugal fans, industrial blowers, and axial fan assemblies. Base frames engineered to minimize transmitted vibration and protect connected ductwork, piping, and electrical connections from fatigue failure.
  • 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.
