Structural Steel Fabrication Credentials India — IS 800 Workshop Documentation for EPC and PMC Teams

Sun Corporation Fabricators & Engineers prepares structural steel fabrication credentials in the format EPC contractors, PMC consultants, and tender evaluation panels actually review — workshop capability, IS 2062 material traceability, qualified welding procedures, NDT records, and stage-gated documentation from material receipt through site handover. The work is fabricated in accordance with IS 800:2007 at our workshop in Hyderabad, Telangana, India.

Why EPC Contractors and PMC Consultants Specify Sun Corporation Fabricators & Engineers

When an EPC contractor shortlists a steel sub-contractor, the questions are practical: Is fabrication done in-house or sent out? Are WPS and welder qualifications on file? Can material be traced by heat number? What inspection records arrive at handover? Does the same contractor erect the steel, or is erection passed to someone else?

Sun Corporation Fabricators & Engineers has fabricated and erected structural steel for industrial and infrastructure work across India for more than 20 years. Core fabrication and core erection are not sub-contracted. Workshop output runs above 500 metric tonnes per month. Most enquiries fall between 100 MT and 5,000+ MT — industrial buildings, highway and railway bridges, metro viaduct steel, airport structures, and process plant steemwork. Documentation is prepared for highway packages, state bridge departments, railway and metro EPC programmes, airport structural steel scopes, and industrial plant contracts where a PMC team holds technical approval.

EPC procurement teams and PMC reviewers can request scope detail and a documentation checklist through our contact page.

Compliance Documentation We Supply on Every Project

Commercial structural steel orders are supported by a documentation set suitable for EPC tender submittals, PMC technical approval, and authority review on highway, railway, metro, airport, and industrial plant contracts. Documents are issued in PDF unless DWG or stamped drawing formats are specified in the contract.

• 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 EPC/PMC submittal registers.

In-House Technical Capabilities — Fabrication to Erection

All structural steel is fabricated at the Hyderabad workshop. Core fabrication scope is not passed to third-party workshops. Site erection is carried out by our own teams on industrial and infrastructure projects across India.

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
• Qualified welding with preheat control on thick plate — electric resistance heating blankets above 30 mm plate, temperature confirmed by thermocouple before welding and monitored through the run
• In-house NDT 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. 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)

Welding is the main review point for PMC teams and EPC QA managers on highway bridges, railway structures, metro viaducts, airport long-span steel, and process plant heavy fabrication. Qualified WPS and PQR records are maintained in the workshop for every process in use. Production welders are qualified to IS 7307 for their assigned categories.
