Steel Fabrication & Certified Welding for Namibia's Harshest Environments

From double coded welding on high-pressure vessels to structural steel erection across mining operations—we deliver fabrication solutions that meet ASME standards and withstand industrial extremes.

Core Fabrication Capabilities

Our workshop in Outapi handles precision shop work, while mobile crews deliver certified welding across Namibia and SADC.

Structural Steel

Fabrication and erection of industrial platforms, walkways, heavy-duty grating, mezzanines, bull bars, roll bars, and structural frameworks for mining and manufacturing facilities.

  • Workshop fabrication with CNC plasma cutting
  • On-site erection, alignment, and grouting
  • Hot-dip galvanizing coordination

Specialized Welding

Double Coded Welding (AWS D1.1 & ASME Section IX), TipTIG technology, and gas welding for hard-wearing special steels like Hardox 400/500. Critical welds undergo NDT inspection.

  • Stainless steel (304/316) TIG welding
  • Hardox wear-plate hard-facing
  • Exotic alloys for chemical processing

Piping & Vessels

High-pressure tanks, vessels, and reinforced HDPE piping (STERIPipe) for drainage, water distribution, and chemical transport. Pressure testing to 40 bar with full certification.

  • ASME Section VIII pressure vessels
  • STERIPipe electrofusion welding
  • Radiographic & ultrasonic testing (RT/UT)

Frequently Asked

Your Questions Answered

Our welders are double-coded to AWS D1.1 (structural) and ASME Section IX (pressure vessel) standards. We also have TipTIG-certified operators for high-integrity stainless steel and exotic alloy work. All critical welds are subject to NDT inspection (radiographic and ultrasonic testing) before sign-off.
Both. Our 2,000m² workshop in Windhoek Northern Industrial handles precision shop fabrication — CNC plasma cutting, coded welding bays, and overhead cranes for heavy assembly. Mobile crews deploy across Namibia and SADC for on-site erection, emergency repairs, and plant shutdown work. Most large projects combine workshop pre-fabrication with on-site installation.
We fabricate and test high-pressure pipe systems and vessels up to 40 bar. All pressure work includes hydrostatic pressure testing, NDT weld inspection, and full certification documentation. We are also an approved STERIPipe supplier for reinforced HDPE piping systems used in water distribution and chemical transport.
We work across carbon steel, stainless steel (304 and 316), Hardox 400/500 wear plate, duplex stainless, and marine-grade aluminum. For corrosion-resistant applications we supply and weld HDPE and PVC piping via electrofusion. Our Walvis Bay team specializes in salt-resistant marine-grade fabrication for the fishing and port industries.
Yes. We maintain a 24/7 standby roster for critical structural and mechanical failures — cracked frames, pressure pipe bursts, and conveyor system collapses. Within Windhoek, our standard emergency dispatch time is under 4 hours. For remote mining and industrial sites we offer rapid mobilization based on your SLA or project agreement.
