Quality Control
ISO 9001 is an internationally recognised quality management standard that ensures our fabrication processes are controlled, consistent, and continually improving. In practical terms, it means every stage of production — from CAD design and material sourcing through to cutting, welding, machining, and final inspection — is managed under a structured system designed to reduce variation and improve reliability.
In fabrication, where precision, tolerances, and repeatability matter, ISO 9001 helps ensure every component is produced to the same high standard, regardless of batch size or complexity.
-
Structural Steel
EN 1090-2 is a European standard that sets the technical requirements for the execution of steel structures, covering how structural steelwork is fabricated and assembled to ensure safety, strength, and compliance for construction use. In practice, it governs how we control welding, cutting, machining, assembly, and inspection processes so that every steel component is produced to a verified standard suitable for load-bearing and structural applications, with full traceability and conformity for CE marking.
-
Supplier Assurance
RISQS (Railway Industry Supplier Qualification Scheme) is the UK rail industry’s supplier assurance scheme, used to verify that companies working on or supplying into the rail network meet the required standards for safety, competence, and compliance. It provides a recognised pre-qualification process that audits a business’s systems, capabilities, and track record so that rail operators and contractors can confidently select approved suppliers.
-
Health and Safety
Acclaim Accreditation is a UK-based health and safety assessment scheme (part of SSIP – Safety Schemes in Procurement) that verifies a company’s health and safety management systems meet recognised legal and industry standards.

Supplier Assurance
Constructionline Gold is a higher-level accreditation within the Constructionline scheme, designed for suppliers who want to demonstrate stronger compliance and capability beyond the standard membership level.
