Quality and compliance are at the heart of everything we do. We operate under the ISO 9001:2008 Quality Management System and have achieved UKCA marking accreditation for structural steel products in accordance with BS EN 1090-1:2009 + A1:2011, certified up to Execution Class 3.
The UKCA mark is a mandatory requirement for manufacturers of structural steelwork, demonstrating compliance with British standards and confirming that all fabricated steel placed on the market meets legal requirements. At Lomas, we have invested heavily in both personnel and quality control systems to ensure we maintain this certification at the highest level year after year.
Our Factory Production Control (FPC) system and Welding Procedure Specifications (WPS) are independently audited annually by SCCS (Steel Construction Certification Scheme Ltd) — a UK Notified Body (No. 2273) under the Construction Products Regulation (CPR 305/2011/EU).
Understanding Execution Classes
Fabricated steelwork is categorised into four Execution Classes, representing the complexity and criticality of the structure:
Execution Class 1 (EXC1): Agricultural buildings (e.g., farm structures)
Execution Class 2 (EXC2): Standard buildings (e.g., residential, commercial)
Execution Class 3 (EXC3): Bridges and complex structures
Execution Class 4 (EXC4): Special structures (e.g., power stations, offshore platforms)
We are certified to Execution Class 3, enabling us to fabricate structural steel for a wide range of demanding projects, from bridges to large commercial and industrial buildings, with the highest standards of quality, precision, and compliance.
