Structural Steel Fabricator Credentials and Quality Records

A structural steel fabrication enquiry should establish the required scope and the records needed for approval: material certificates, applicable welding procedures, welder qualifications, an inspection plan and release documentation. Send the drawing register and document checklist so availability, submission dates and responsibilities can be confirmed. See our fabrication process for scope guidance.

Documents to request before placing an order

Match each requested record to the work: steel grade and thickness, weld joint, inspection method, coating system and site scope. Check the document revision, validity and applicable range before accepting it for the order.

Confirm the scope and evidence

Confirm where fabrication will take place, who prepares shop drawings, which operations are included, how inspection is arranged and who is responsible for transport and erection.

Sun Corporation Fabricators & Engineers accepts structural steel fabrication and erection enquiries for industrial and infrastructure work. Workshop loading, delivery lots, inspection arrangements and any subcontracted operations must be agreed against the drawings and programme before order placement.

Use our enquiry page to send the required scope and document checklist.

Workshop and Fabrication Capacity

The Hyderabad workshop handles industrial and infrastructure steel — standard building frames and pipe racks through heavy plate girders, crane runway beams, and process plant structures. Shop drawings are prepared in-house in Tekla Structures, with piece marks, weld details, bolt positions, and erection weights issued before cutting starts.

Quality Documentation to Agree for the Project

Agree the document register before production: required records, responsible parties, review status and file formats. Drawings, material certificates, welding records, inspection reports and handover records should identify the relevant member marks and revisions.

• Mill Test Certificates (MTCs) — IS 2062 grade confirmation with heat number traceability for all structural steel sections and plate
• Weld Procedure Specifications (WPS) and Procedure Qualification Records (PQR) — Qualified to IS 9595 for carbon and carbon-manganese steels; AWS D1.1 referenced where specified in the contract
• Welder Performance Qualification (WPQ) records — Individual welder certification to IS 7307 for assigned process, position, and thickness range
• Shop drawings and general arrangement drawings — Prepared in-house from the structural engineer’s approved design; issued for client and consultant approval before fabrication release
• Inspection Test Plan (ITP) — Stage gates with hold and witness points aligned to the EPC QA plan
• Non-destructive testing reports — UT, MPI, and PT records for welds requiring volumetric or surface inspection
• Dimensional inspection records — Checked against IS 800:2007 Annex F fabrication tolerances
• Surface treatment and coating records — Blast profile and paint dry film thickness readings where specified
• Dispatch documentation — Packing list with piece marks and heat number cross-reference
• Erection records — Method statement, plumb and level survey records per IS 800:2007 Annex G erection tolerances
• Project quality dossier at handover — Compiled MTC, weld, dimensional, NDT, and coating records for close-out

Where the contract requires statutory or client-specified third-party inspection, inspector access is arranged during production so findings can be cleared before work progresses beyond practical correction.

Documentation scope follows project-specific contract requirements and project document registers.

In-House Technical Capabilities — Fabrication to Erection

Confirm the workshop location, fabrication operations, any subcontracted work and site erection arrangements during technical review. Record supervision, inspection and handover responsibilities in the agreed scope.

Scope under one contractor includes:

• Shop drawing preparation from the structural engineer’s approved design drawings (Tekla Structures)
• Steel procurement from approved Indian mills with incoming inspection and heat tagging
• CNC cutting, drilling, forming, and assembly
• Welding to the applicable procedure, with preheat and interpass temperature requirements defined for the material, thickness, joint restraint and hydrogen control
• Project-specified weld and dimensional inspection
• Shot blasting, primer, and industrial painting per specification
• Transport and pan-India logistics
• Crane-assisted site erection, alignment survey, and bolted connection completion

Shop drawing connections are checked against IS 800:2007 Section 10 against the approved structural design — Sun Corporation Fabricators & Engineers does not provide independent statutory structural design certification. Fabrication scope detail is on our structural steel fabrication India page. For manufacturer selection see structural steel fabricators in India. Heavy plate, crane girder, and vessel work is covered on heavy steel fabrication India. Erection scope is on structural steel erection India.

Welding Procedures and Welder Qualification (WPS / WPQ)

For welded steelwork, request the applicable WPS, supporting procedure qualification where required, and welder qualification records covering the joint, process, material and thickness range. Agree NDT methods, extent, personnel qualifications and acceptance criteria in the inspection plan. Confirm the contract standards before fabrication release.
