Structural Steelwork in Seaham
J&N Steelcraft UK Ltd provides structural steelwork across Seaham, County Durham and the surrounding area — design, manufacture and installation under one roof, UKAS-approved to EN1090-1 Execution Level 3.
Seaham is our nearest coastal town, a few minutes north of the Peterlee workshop, and its former harbour and colliery land have become one of the area's most active regeneration fronts around the marina and Byron Place. We supply steel fabrication across the town — structural frames and mezzanines for commercial units, plus balustrades, canopies and railings finished to cope with the seafront environment.
Our structural steelwork forms the backbone of commercial units, industrial facilities, mezzanines and extensions across the UK. From a single beam to a complete portal frame, every project is engineered for strength, safety and a precise fit on site.
We manage the full journey in-house - site survey, load calculations, connection design, fabrication and on-site erection - so there is a single point of responsibility from drawing board to handover. All fabrication is carried out to UKAS-approved EN1090-1 Execution Level 3.
Whether you are a main contractor, architect or developer, we work to your programme and specification, delivering steelwork that is ready to install and right first time.
