Stainless Steel Fabrication in Nairobi — A Practical Guide
Stainless steel fabrication in Nairobi has exploded — and so have the corner cuts. Most jobs that fail in the first year fail for the same three reasons: the wrong grade of steel, weak welds, and finishes that trap bacteria. Here is what a serious fabrication brief should specify.
Grade matters
Insist on AISI 304 for anything that touches food, water or chemicals. 201 is cheaper, looks identical, and rusts within months in a wash-down environment. Ask for the mill certificate. A reputable fabricator will hand it over without hesitation.
Welds are the story
TIG welds on food contact surfaces should be continuous, pickled and passivated — not "stitched" with grinder marks left behind. Stitch welds harbour bacteria and corrode from the inside out. On structural frames, MIG is acceptable but seams should still be ground flush.
Finish — #4 or better
A proper #4 brushed finish (Ra < 0.8 µm) sheds dirt and resists corrosion. Mirror polish looks great in showrooms; brushed wins in the kitchen.
Designed for cleaning
Coved internal corners. No hollow legs that fill with water. Removable shelves. Adjustable bullet feet for floor levelling. If your fabricator hasn't asked about your cleaning chemicals and water hardness, they are guessing.
What we build in Industrial Area
At Karisma Modern Kitchen, our Industrial Area workshop turns out cold rooms, milk processing tanks, water purification vessels, hospital trolleys, school boilers, butchery tables and full commercial kitchen suites. Every job ships with a mill certificate, a 12-month workmanship warranty, and installation by our own team — not subcontractors.
We've delivered for KenMeat, Farmer's Choice, the United Nations Office Nairobi, Equity Bank, Kenya Defence Forces and over 200 SMEs across the country. Each project starts with a site visit and an AutoCAD layout, so what you sign for is exactly what gets installed.
Quick checklist before you sign
- AISI 304 confirmed in writing
- Mill certificate at delivery
- TIG-welded, pickled and passivated food-contact surfaces
- #4 brushed finish minimum
- Coved corners, removable parts, adjustable feet
- 12-month workmanship warranty
- Installation and staff training included
Stainless steel done right outlasts the business that bought it. Ask the hard questions before the deposit.
