TECHNICAL SERVICE SPECIFICATION

Structural Steel Fabrication & Certified Welding

Custom industrial steel structures and coded pipe fabrication engineered to structural tolerances.

Certified welder executing TIG pipe weld in engineering workshop
FIELD EXECUTION // AWS D1.1

Governing Standard

AWS D1.1 / BS EN 1090 Execution Class 2 / ISO 3834

Service Overview

We fabricate in our workshop and erect on site. All structural welding is executed by qualified personnel under EN 287-1 and AWS D1.1 certifications, with non-destructive testing (NDT) documentation provided on completion.

Plant Equipment & Systems Covered

  • Catwalks, industrial access stairs, caged ladders, and safety handrail systems
  • Heavy equipment skid frames, condenser support steel, and vessel saddles
  • Overhead pipe gantries, cable bridge crossings, and structural roof framing
  • Machine guards, safety bollards, and heavy-duty barrier protection
  • On-site modification and reinforcement of existing plant structural beams
  • Ultrasonic, magnetic particle (MPI), and dye penetrant testing (DPT) reports

Standard Execution Procedure

  1. [1]Detailed 3D structural shop drawing generation and connection design
  2. [2]CNC profile cutting, shearing, punching, and sub-assembly tacking
  3. [3]MIG, TIG, and SMAW welding by certified 3G/4G/6G welders
  4. [4]Abrasive grit blasting (Sa 2.5) and industrial epoxy or hot-dip galvanizing coating
  5. [5]Crane rigging and bolt-up installation with torque audit logs

What We Need From You to Quote
