Executive Statement

Demonstrable, auditable certainty

We fabricate and install for copper, cobalt, gold, platinum, chrome, manganese, coal and industrial-minerals operations. Our core differentiator is corrosion-service competence: the duties that dominate Solvent Extraction and Electrowinning circuits, and which punish any contractor whose material control, welding metallurgy and passivation discipline is anything less than exact.

Every item we release carries a traceable identity. That is what the client actually buys — not steel, but certainty that stands up to third-party audit.

Corrosion-service competence

Acid, chloride, organic and slurry duties in SX and EW circuits — material control, welding metallurgy and passivation discipline held to the exact specification.

Absolute traceability

Mill certificate to heat number, to the qualified welder, to the radiograph, to the hydrostatic test, to the Manufacturer's Data Record that hands it over.

Schedule integrity

We commit only to dates we have resource-loaded and can defend, with modularisation used to shift work off the critical path.

Core Scope of Supply

Six disciplines, one accountable contractor

Structural Steelwork

Plant structures, conveyor gantries, tank farms, pipe racks, silos and platework supports fabricated to SANS 2001-CS1 / AISC and erected to survey-verified tolerance.

  • S355JR / S275JR light, medium and heavy structural steel
  • Conveyor gantries, trestles, chutes, head and tail structures
  • Crane runway beams, monorails and maintenance lifting steel

Stainless Steel Tankage

SX/EW mixer-settlers, electrolyte and organic tankage in 304L / 316L / 2205 duplex to API 650 App. S, EN 14015 and BS 4994 principles.

  • Physically segregated stainless bay — no carbon migration
  • Full back-purge with oxygen verified below 50 ppm
  • Pickling and passivation to ASTM A380 / A967

Carbon Steel Tankage

Leach tanks, thickener launders, water, reagent and fuel storage to API 650 / AWWA D100, internally lined where the duty requires it.

  • A516 Gr. 70, Corten and AR400/450 abrasion-resistant grades
  • Rubber, HDPE, epoxy-novolac and glass-flake lining interfaces
  • Vacuum-box floor weld testing and hydrostatic acceptance

Process Piping

Stainless and carbon steel spool fabrication and installation to ASME B31.3 with full spool traceability and HDPE/GRP interface management.

  • Raffinate, electrolyte, organic, acid, slurry and steam services
  • DN15 – DN900 spool fabrication in a dedicated spool bay
  • Orbital cutting, machined bevels and controlled fit-up

Site Erection & SMPP

Shutdown and greenfield mechanical installation, rigging, alignment, torquing and pre-commissioning support across the SADC region.

  • Resource-loaded shutdown planning to Primavera P6 / MS Project
  • Certified rigging inventory with current load-test records
  • Modularisation to shift work off the critical path

Supply & Trading

Commercial supply of structural steel sections, flanged piping, plate, fittings and electrical components, with detailed fabrication and erection drawings.

  • Mill-certified material with heat-number traceability
  • Detailed fabrication and erection drawing packs
  • Cross-border logistics, permitting and customs clearance
