Engineering Capabilities & QA/QC

We deliver to 25+ African countries. Our highest-volume corridors run from our Germiston plant into Zambia, the DRC, Botswana, Zimbabwe, Mozambique and Namibia by road, with sea legs through Durban to Dar es Salaam and Mombasa for East African destinations. Our in-house logistics desk handles SADC certificates of origin, customs clearance, abnormal-load permits and escort coordination on every consignment.

Our 45 000 m² Germiston facility sustains 3 500 tons of fabricated structural steel per month across automated beam lines, plate processing and welding bays. We handle sections to 1 250 mm depth, plate to 100 mm thickness and single pieces to 30 m without splicing.

Yes. We accept Tekla, IFC, SDNF and CIS/2 models as well as AutoCAD DWG drawing sets. Our detailing bureau reviews the model, resolves connection design, runs clash detection against your MEP models and generates the NC data that drives our CNC lines directly — which removes the manual transcription step where most fabrication errors originate.

It depends on the actual micro-environment, not a generic classification. Flotation and electrowinning interiors are ISO 12944 C5-I and need a zinc-rich primer with a vinyl-ester or high-build epoxy topcoat at 400–500 µm total DFT. External mining structures usually sit at C4 and take a 300 µm three-coat system. Coastal and port work is C5-M, where we specify a duplex system — hot-dip galvanizing swept-blasted and overcoated with polysiloxane.

For a 2 000–3 500 ton mining or industrial structure, budget 6–8 weeks for detailing and approvals, 12–20 weeks for fabrication and coating, and 3–6 weeks for cross-border transit and site delivery depending on corridor. Fabrication overlaps with detailing once approved drawings are released area by area, so the critical path is usually shorter than the sum of those figures.

We are certified to ISO 9001:2015 for quality management and ISO 3834-2 for comprehensive quality requirements in fusion welding. Welders are coded to ASME Section IX and welding runs to AWS D1.1 procedures. Non-destructive testing is witnessed by third-party inspectors from SGS or Bureau Veritas where the contract requires it, and every consignment ships with its inspection release notes, DFT records and material certificates.

Both. Roughly two-thirds of our contracts are supply-and-erect, where our own site crews and supervision handle assembly, bolting and survey verification anywhere across the continent. We also supply fabrication-only where the client already has an erection contractor mobilised — in that case we pack and mark consignments in erection sequence and provide erection drawings and supervision on request.

At minimum: project location, approximate tonnage, structure type and target erection date. To price accurately we want general arrangement drawings or a 3D model, the design code and steel grades called for, the corrosion specification, and whether the scope is supply-only or supply-and-erect. Our estimation bureau responds to complete RFQs within 24 hours and issues a firm priced proposal within five working days.
