Pre-Fabrication & Sub-Assembly Services
From Cut Parts to Ready-to-Fit Assemblies
- One roofCut, formed and welded
- ISO 3834Certified welding quality
- ISO 9001Certified quality system

At National Stainless Steel Centre (NSSC), pre-fabrication and sub-assemblies bring our cutting, forming, machining and welding together under one roof. Your structural sections, pipes, flanges and plate work leave our Kempton Park facility as ready-to-fit components, with less work left for site.
We build in the stainless steel grade you specify, including duplex, super duplex and special alloys, and we can source exotic materials that are hard to find locally. Every weld is made to ISO 3834 by qualified, coded welders.
Our live MRP and ERP systems track each job from material to dispatch, so your assemblies are planned with the rest of your project.
40+ Years of Expertise
Decades of stainless steel processing experience, trusted by leading industries across South Africa and beyond.
Strategic Kempton Park Location
Centrally based near OR Tambo International Airport for rapid distribution across South Africa and Sub-Saharan Africa.
Efficiency & Sustainability
Optimised nesting, energy-efficient processes, and minimal material waste support both cost savings and sustainability goals.
State-of-the-Art Technology
Advanced CNC, laser, plasma, waterjet, and robotic systems delivering precision, speed and repeatability.
Integrated Services Under One Roof
From cutting and bending to welding and polishing, a streamlined workflow that saves time and reduces coordination risks.
Custom Solutions, Zero Compromise
Every project is tailored to your specs from prototyping to high-volume production runs with consistent results.

Our Pre-Fabrication Capabilities
We build components and sub-assemblies to your drawings, with the same machines and teams as our individual services.
- Assemblies of structural sections, pipes, flanges, plate work and more
- Cutting by laser, plasma, water jet and guillotine
- Forming by CNC bending, plate and section rolling, and tube bending
- Machining, milling and drilling for precision-fit parts
- Welding by MIG, TIG, keyhole TIG and SAW, manual and robotic
- Finishing by polishing and deburring, with protective PVC film where needed
- All grades, including duplex, super duplex and special alloys
How it works
Send your drawings
Email DXF, DWG or PDF drawings of the parts and the assembly to info@nssc.co.za, or use the form below.
Get your quote
We confirm the grades, parts, welding, finish, quantities and lead time, and send you a quotation.
We build and check
Your parts are cut, formed and machined in-house, welded into assemblies and checked against your drawing.
Collect or delivery
Collect from our Kempton Park facility, or we deliver nationwide across South Africa.

Why Choose NSSC?
One supplier for the material and the work: we stock stainless steel in all grades and process it in-house, so your parts pass between fewer hands and fewer suppliers.
Our quality system is accredited to ISO 9001 and our welding to ISO 3834, both audited by TÜV Rheinland South Africa, and our welding procedures are qualified to ASME IX and BS EN ISO 15609-1.
Custom Projects. Zero Compromise.
We work from your drawings and specifications, for a single assembly or a production run. Our process includes:
- Reviewing your drawings and specifications
- Sourcing the material, including exotic grades
- Cutting, forming and machining every part in-house
- Welding and finishing each assembly
- Checking each assembly against your drawing before dispatch

Frequently asked questions
What is pre-fabrication in stainless steel?
Pre-fabrication means building components and sub-assemblies in our facility before they go to site. Parts are cut, formed, machined and welded at NSSC, so they arrive ready to fit, with less work left on site.
What can NSSC pre-fabricate?
We pre-fabricate structural sections, pipes, flanges, plate work and other stainless steel components to your drawings, from a single assembly to a production run.
Which stainless steel grades can NSSC fabricate?
We work in all stainless steel grades, including duplex, super duplex and special alloys. We can also source exotic materials that are hard to find locally.
Are NSSC sub-assemblies welded to a certified standard?
Yes. NSSC is accredited to ISO 3834 for welding quality and to ISO 9001, audited by TÜV Rheinland South Africa. Our welding procedures are qualified to ASME IX and BS EN ISO 15609-1, and our welders are qualified and coded.
What should I send for a pre-fabrication quote?
Send DXF, DWG or PDF drawings of the parts and the assembly, with the grade, quantities and any finish or inspection requirements. Email them to info@nssc.co.za, or send your details with the form on this page.
Can NSSC supply quality documents with my assemblies?
Yes. We support the preparation of quality control documents, NDT requirements and project planning, so the records your project needs come with your assemblies.
