Steel supplier audit

Establish independent verification of supplier welding, coating and documentation to support compliant and reliable delivery of steel structure

Auditor reviewing welding setup and process parameters during a steel supplier audit.

Steel construction projects depend on suppliers who control welding, coating and documentation according to project and standard requirements. When supplier practices are unclear or inconsistent, defects often surface late in fabrication, causing weld repairs, premature coating failure or incomplete documentation at delivery.

This leads to rework, delays and additional cost, while contractors and owners still carry the burden of proving compliance. Steel supplier audits provide early, independent verification that fabrication processes meet contractual and regulatory requirements.

Evaluations cover welding and coating practices, documentation control, traceability and process management, replacing uncertainty with documented insight into supplier performance.

Clear audit reports document findings and deviations, providing reliable evidence of supplier competence and a solid basis for approval, corrective actions, follow-up and project documentation.

Challenges

When supplier processes lack transparency, project risk escalates

Differing international, European and client requirements create compliance gaps
When suppliers interpret overlapping international, European and project-specific requirements differently, inconsistencies arise that increase non-compliance risk and complicate approval.

Unclear welding and coating control leads to hidden defects
Without insight into how suppliers manage critical fabrication processes, quality issues often remain undetected until production is underway.

Incomplete documentation prevents compliance verification
Gaps in traceability and records make it difficult to demonstrate that requirements have been met.

Inconsistent standard interpretation creates uneven quality
Differing views on EN 1090 and project-specific requirements increase the risk of non-compliance across suppliers.

Late identification of deviations causes rework and delay
Issues discovered after fabrication starts drive corrective work, schedule impact and disputes over responsibility.

Benefits

Create a clear basis for supplier approval and corrective actions

Experienced auditors, verified supplier performance

Certified lead auditors evaluate welding, coating and documentation control with technical precision, ensuring fair assessments and reliable conclusions.

Let's make sure your suppliers meet every requirement

Knowing where to start can be difficult. A brief conversation can clarify the type of audit you need, when it should occur and how it supports your project documentation.

Service scope

Evaluation focus, method and documentation

Assessments focus on welding and coating processes, documentation routines, traceability and management systems.

Standards

Audits and evaluations follow recognised standards for steel fabrication and supplier quality systems

Execution of steel structures: Defines conformity assessment and factory production control requirements for manufacturers supplying load-bearing steel components.
Quality requirements for welding: Specifies how suppliers must control welding operations, personnel qualifications and documentation to ensure consistent fabrication quality.
