Mechanical
Design & Build.

Boilers, pressure equipment, process piping and quality management — designed, built and signed off by one team, so nothing gets lost between drawing and plant.

What We Do

Four Disciplines, One Accountable Team

Most fabrication shops hand a job between three companies before it's on site. Here, the same team runs the calculation, cuts the metal, and signs the data book.

01 — Design
Mechanical & Piping Engineering

Pipeline routing, material selection, equipment sizing, strength calculations, stress analysis and 3D modelling — worked from first principles in industry-standard analysis and CAD software, and checked against ASME B31, API and BS/EN codes. Every number in the report is traceable back to a calculation, not a rule of thumb.

Welding & Fabrication

Where the company started, and still the core of the business — welding carbon steel, stainless, duplex, super-austenitic, nickel alloys and titanium for boilers, pressure equipment and piping, to American and European codes. Every weld is logged through our own mobile app and rolled up into a live dashboard, not a paper traveller.

  • High-Grade Alloy Welding
  • Weld Traceability & Data Dossiers

03 — Project & Quality Management
On-Site Resourcing

Project and construction managers, quality coordinators, and SAIW/API-registered QC inspectors supplied directly onto client shutdowns and capital projects — not managed at arm's length. Data books are complete when the job hands over, not chased for months afterward.

  • NDT Coordination
  • Data Book Management

04 — Construction
Construction & Installation

Piping, pumps, valves, tanks and structural steel, fabricated and installed by the same team that did the engineering — which cuts out a layer of translation between drawing and site.

  • Structural Steel

Who's Doing the Work

A small, code-literate team — not a call centre routing you to a subcontractor.
