SC4 Fabrication

SC4 fabricate structural steel buildings for a wide variety of sectors: multi-storey car parks, commercial buildings, schools, rail, bridges and other defence and energy infrastructure up to an including Execution Class 4.

To ensure your project is completed to specification and schedule, we only employ time served and multi-skilled fabricators and welders. Meaning you will always have a specialist team of experts working on your project.

SC4 are an accredited steel fabrication facility and certified to BS EN 1090-1/2 up to Execution Class 4 (the highest achievable quality standard, which ensures the most stringent set of controls, necessary on safety critical structures that would have a high consequence of failure). All structural steel products produced here are UKCA Marked.

Welding Quality

All steel fabrication and welding at SC4 is conducted using BS EN ISO 3834-2. This is a Welding Quality Management System that requires specialist management, personnel and procedures. We have developed a suite of weld procedures, employ highly skilled qualified welders to BS EN 9606-1 and oversee projects with our own in-house Responsible Weld Coordinator (RWC) and CSWIP weld inspectors. Additionally, we have a robust Quality Assurance process that enables us to offer full traceability and control over the fabrication quality.

All this enables SC4 to deliver your project to a high standard whilst maintaining an efficient turnaround time.
