Metal Fabrication Nigeria — Structural Steel, Process Piping and Industrial Metalwor
Karoch Engineering fabricates structural steel, process piping, equipment skids, and precision metalwork from our Ibeju-Lekki, Lagos facility — with MIG, TIG, and MMA welding capability and full surface treatment in-house.
Metal Fabrication for Industrial Nigeria — Not Just Workshop Output
Metal fabrication for industrial clients in Nigeria requires more than a workshop with welders. It requires dimensionally accurate fabrication, correct material certification traceability, appropriate weld quality for the application, and surface treatment that survives Nigerian coastal and industrial environments. Karoch Engineering delivers all four.
What We Fabricate
▸ Structural steel fabrication — portal frames, columns, beams, bracing, and connection plates to structural drawings
▸ Process pipework fabrication — carbon steel, stainless steel, and duplex piping spools to isometric drawings
▸ Equipment skid fabrication — structural and process skids for pump packages, filter units, and process equipment
▸ Pressure vessel fabrication — storage vessels, separators, and process vessels to ASME or BS PD 5500 (project-specific)
▸ Pipe supports and hangers — fabricated pipe support systems for industrial pipework installations
▸ Tank fabrication — welded carbon steel and stainless steel tanks for non-FRP applications
▸ Precision metalwork — machined components, brackets, flanges, and bespoke metalwork to tight tolerances
▸ Surface treatment — in-house grit blasting and multi-coat paint application before despatch
Welding Quality That the Documentation Proves — Not Just That We Claim
Karoch Engineering maintains welding procedure qualification records and welder qualification certificates for the welding processes we use. For projects requiring coded welding, we provide the documentation trail from WPS through welder certs to joint inspection records. Our quality system is not a promise — it is a document file.
FAQ
Fabrication Questions
Q: Do you weld to ASME IX or BS EN ISO 15614 procedures?
A: Yes — Karoch Engineering maintains qualified welding procedures to project-specific codes. Confirm the code requirement at the project scope stage and we will confirm the applicable WPS documentation.
Q: Can you fabricate and deliver structural steel to site outside Lagos?
A: Yes — we fabricate in Ibeju-Lekki and deliver to site across Nigeria. For large structural deliveries, we manage oversize load permits and specialist transport as required.
Q: Do you provide material test certificates (MTCs) with fabricated steelwork?
A: Yes — material traceability and MTCs for structural and pressure-retaining items are provided as standard for projects where this is specified.
