CROWN INDUSTRY

Established

Crown Industry was established in 2017 and has developed strong capabilities in heavy steel fabrication, large structural assemblies and infrastructure components.

RDSO Focus

The company achieved RDSO certification/approval in 2024 and has built its fabrication systems around controlled material, welding, inspection and documentation processes.

Manufacturing Scale

More than 25,000 m² manufacturing facility, stated fabrication capacity above 900 MT/month and current single-piece fabrication above 40 MT and 43 m length.

CORE POSITIONING

• Steel bridge and structural fabrication for railway and infrastructure projects
• Large welded plate girders, open web/truss and bridge-related structures
• Controlled fabrication supported by QAP, WPSS, inspection and traceability
• Capability for trial assembly, surface protection, dispatch and site execution support

VISION

To be a trusted and innovative leader in steel bridge and structural fabrication, setting high benchmarks in quality, safety and engineering excellence for infrastructure projects.

MISSION

Deliver high-quality steel structures through disciplined fabrication, skilled teams, controlled welding and inspection, safe working practices and dependable project delivery.

VALUES

Integrity • Quality • Innovation • Customer Focus • Safety • Teamwork • Sustainability

RDSO APPROVED / CERTIFIED CAPABILITY

Crown Industry achieved RDSO certification/approval in 2024. The company’s steel fabrication infrastructure is intended to support railway and infrastructure structures requiring controlled material verification, welding procedures, inspection, trial assembly and final release.

CONTROLLED RELEASE

Trial assembly verifies geometry, alignment, camber and bolt-hole fitment. Final inspection, identification, protection and dispatch documentation are controlled before release.

Production Controls

• Approved drawings and project technical requirements are reviewed before production.
• QAP and WPSS are prepared and submitted for approval before fabrication.
• Material certificates, inspection records and NDT reports are maintained in job documentation.
• Certificate / approval evidence can be included with project submissions and technical documentation.

Large Assemblies

Large single-piece or assembled structures with trial assembly, inspection and dispatch planning.

WELDING CONTROL

• WPSS prepared for the applicable joint, welding process and position.
• Consumables, welding parameters, preheat/interpass requirements and sequence are controlled through approved procedures.
• SAW and manual/semi-automatic welding processes are used according to fabrication requirements.
• Fit-up and weld visual inspection are carried out before acceptance.

NDT / TESTING

• UT / VT / RT / DPT or other NDT as specified by approved QAP and applicable requirements.
• Inspection results are documented and linked to the job / component identification.
• Mechanical and weld qualification testing can be arranged as required by the approved procedure and inspection plan.

TRACEABILITY

Material identity → cutting / component marking → fit-up → welding → inspection / NDT → trial assembly → surface protection → final identification → dispatch documentation

TRIAL ASSEMBLY

• Full or specified trial assembly as required by drawings / inspection plan.
• Check fit-up, alignment, camber, straightness, Squareness and bolt-hole matching.
• Record discrepancies and complete rectification before final inspection.
• Identification and marking support correct dismantling, transport and site erection.

SURFACE PROTECTION & DISPATCH

• Abrasive blast preparation to the specified surface standard.
• Metalizing / zinc spray where specified by the project.
• Primer and finish coating system with DFT verification.
• Final marking, packing and lifting/transport preparation.
• Dispatch documentation including inspection release, MTCs and as-built records as applicable.
