What We Do

We do not sell catalogue products. We fabricate to the drawings and work orders our customers give us. These are the assemblies we build most often.

• Casings: Fan and equipment casings, panelled and stiffened, fitted up and checked against drawing.
• Cylindrical Silencers: Round silencer shells and internals for intake and exhaust duty, rolled, welded and finished to size.
• Rectangular Silencers: Silencer casings with splitter panels for fan and air handling systems, fabricated, painted and marked to drawing.
• Conical Hoppers: Large tiered conical hoppers built segment by segment with stiffener rings and gussets.
• Dampers: Damper frames and housings fabricated to customer drawings for air and gas flow control.
• Ducts: Rectangular and round ducting with flanges and stiffeners for air and flue gas handling.
• Towers: Tower sections and structural assemblies fabricated in segments for site erection.

How a Job Runs

1. Drawing and Work Order: We study your drawing, confirm material, quantities and delivery, and raise any clarifications early.
2. Marking and Cutting: Plates and sections are marked out and cut to size with gas cutting and drilling.
3. Fit-Up and Welding: Assemblies are fitted on jigs and welded with MIG and inverter welding sets by skilled welders.
4. Inspection: Dimensional checks in-house. NDT (MPT, RT, UT) and chemical analysis through third-party agencies when specified.
5. Painting and Marking: Surface preparation, primer and paint as specified, then stencil marking with work order, quantity and weight.
6. Packing and Dispatch: Wrapped and secured for transport, and dispatched to your plant or site.
