  • Steel castings, stainless steel castings (including duplex stainless steel), iron-chromium-nickel-molybdenum corrosion resistant and specialty irons

  • Argon Oxygen Decarburisation (AOD) – combining higher metallic yields with lower material costs allowing greater accuracy in chemistry control for carbon and rapid desulfurisation and resulting in a cleaner metal

  • CNC pattern making (wood, foam, aluminium and urethane)

  • Solidification modelling – cutting edge foundry modeling software ensuring highest quality through the 1st article process

  • Fabrication/weldments to casting and forging to casting conversions

  • Non-Destructive Testing (NDT) – visual, liquid penetrant, magnetic particle, ultrasonic, X-Ray (including Linatron capabilities up to 22″ section thickness)

  • Value added services – rough and finish machining, hydro-testing, light fabrication and assembly
