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)
