Capability
What we
deliver.
From 3D CAD modelling and Eurocode connection design through clash detection and erection sequencing — every drawing is produced by engineers integrated with the fabrication floor, ensuring buildable details and signed-off releases to site.
Phase 01
3D CAD modelling
Full 3D models in Tekla / Advance Steel, co-ordinated against architectural and MEP backgrounds.
- GA drawings
- Part marks
- NC / DXF output
Phase 02
Connection design
Bolted and welded connections designed to Eurocode 3 and reviewed under a documented design checking process.
- Eurocode 3 designed
- Bolted & welded
- Documented checking
- Sign-off controlled
Phase 03
Clash detection
IFC exchange with architects, MEP designers and concrete subcontractors — clashes resolved at design stage, prior to fabrication.
- IFC exchange
- Architects & MEP
- Concrete sub co-ord
- Resolved pre-fab
Phase 04
Erection sequencing
Phased GAs and lift plans aligned to the principal contractor's construction programme and site access.

Why design with us
Designed by the team that will fabricate it
Drawings are produced by engineers integrated with the production facility — ensuring details are buildable, weld access is realistic and tolerances align with the cutting and drilling equipment in the workshop.

Engineering
Structural steel engineering and design
In-house engineers translate architect intent and SE calculations into fabrication-ready structural steel drawings. 3D models, GA layouts, connection details and erection sequences — all coordinated against the workshop equipment and the site programme.
Connections are designed to Eurocode 3 and checked by a chartered engineer. Models exchange via IFC with architects, MEP designers and concrete subcontractors, so clashes are resolved before steel is cut.
Buildable from day one
Engineers and detailers walk the metal fabrication workshop daily. Details account for weld access, plate tolerances and the actual capability of our cutting and drilling lines.
Phased for erection
Erection sequences are tied into site installation plans and lift schedules, so the GA you sign off is the GA that gets built.
FAQs
Engineering & design,
answered.
How CR Steel turns the structural engineer's calculations into fabrication-ready, clash-resolved structural steel drawings — produced by engineers integrated with the workshop.
- An in-house engineering team using Tekla Structures and Autodesk Advance Steel produces the 3D model, GA drawings, part marks and NC / DXF output. Detailers work alongside the fabrication shop so every drawing reflects the cutting, drilling and welding capacity actually available.
