Nine clusters, each mapped to a capability or product page.
32Stamping, presses and press toolsPressed, punched and deep drawn sheet metal parts, the tooling that makes them, and the DFM rules that decide whether a part suits a press at all.29Laser cutting and sheet metal fabricationFibre laser cutting, nesting, edge quality, tolerance and the cost drivers behind a cut part, including long panels cut on the 40 ft × 16 ft bed.38Bending, welding and finished assembliesPress brake bending, bend allowance, fixtures, robotic MIG welding, distortion control and the tolerances a finished welded assembly can actually hold.28Surface treatment and powder coatingSeven-tank pretreatment, phosphating, shot blasting, powder and wet paint selection, film thickness and the failure modes that show up two monsoons later.22Elevator and lift componentsCounterweight frames, car frames, slings, guide rail brackets, door panels and controller enclosures made to lift OEM drawings.24Genset, canopy and acoustic enclosuresDG set canopies, acoustic panels, louvres, base frames, skid bases and control panel enclosures, engineered for weather, access and noise.28Data centre racks and electrical enclosures19-inch rack frames, mounting rails, perforated doors, blanking panels, PDU brackets and the electrical enclosures around them.16Tractor, forklift and material handlingTractor panels and brackets, forklift overhead guards, counterweight covers, mast parts and material handling components built for vibration and abuse.16Railway, furniture and infrastructureRailway coach panels, underframe brackets, fittings, metal furniture frames, shelving and signage, where standards and traceability carry as much weight as the part.38Materials and gradesGrade selection for CRCA, stainless, aluminium, brass and copper: formability, thickness, corrosion and what the mill certificate actually guarantees.30Standards and complianceWhich standard applies, what it actually covers, and the evidence a buyer should ask for: ISO, IEC, EN, RDSO and material certification.44Design and CADDesign rules, CAD hand-off, bend allowances, tolerance stacks and the drawing notes that decide whether a part is made right first time.4Applications and casesApplication-led problems from lift shafts, genset sites, data halls, railway coaches, farms and warehouses, and how the part is designed around them.28Plant, quality and sustainabilityHow the plants run: quality systems, inspection, calibration, pretreatment chemistry, effluent, maintenance, energy and scrap.
