Services
Estimating
Our estimating service provides accurate financial projections for steelwork projects using detailed breakdowns. We identify cost-saving opportunities while maintaining quality standards. This service ensures clients receive transparent budget planning from initial concept stages.
Design / Modelling
We utilise Tekla software for precise 3D structural modelling that visualises complete steel frameworks. This service enables clash detection and error checking before fabrication begins. Our digital models ensure perfect component alignment during construction phases.
Detailing
Our detailing service creates comprehensive fabrication drawings with exact specifications. We produce shop drawings that guide CNC machinery operations. This ensures every steel component meets dimensional accuracy requirements before manufacturing.
Fabrication
We fabricate steel components using modern CNC machinery with precision cutting, welding, and surface treatment. Our facility handles shotblasting and painting to client specifications. Quality control measures ensure compliance with industry standards throughout production.
Erection
Our experienced teams install structural steelwork following strict safety protocols. We coordinate with contracts managers to ensure accurate beam and column placement. This service guarantees structural integrity through professional assembly techniques.
