Steel Detailing
Steel Detailing
At SQR Engineering, we transform design intent into precise, buildable documentation. Our detailing process bridges the gap between structural design and fabrication — ensuring that every component fits, aligns, and performs exactly as intended.
Our in-house team develops comprehensive design, aligned with each client’s standards and workflows. This includes:
- 3D Modeling of steel structures
- General arrangement (GA) drawings for approval and construction
- Fabrication drawings
- Erection and marking plans
- Bills of materials (BOMs) and bolt lists
- NC and other CAM data export
- Revision management and RFIs (requests for information)
VARIOUS BUILDING TYPES/POSITIONS
We work on a wide range of steel structures, including:
- Industrial and commercial buildings
- Auxiliary and support structures
- Platforms, stairs and canopies
- Façade substructures and architectural steelwork
- Crane girders and runways
- Reconstructions and retrofits
SOFTWARE & TOOLS
- Autodesk Advance Steel — 3D modeling, erection drawings, and automatic generation of fabrication drawings, NC/ CAM data export.
- Autodesk AutoCAD — Detailing and client-specific drawing customization.
- BIM Collaboration Tools — Coordination with architects and other engineers through model exchange and markup.
WORKFLOW AND QUALITY CONTROL
Our detailing process is fully BIM-integrated, using Autodesk Advance Steel and AutoCAD as our core platforms. Model coordination, clash checks, and drawing reviews are embedded into each stage of production.
Every drawing undergoes internal technical review by our engineers before delivery, ensuring consistency, accuracy, and compliance with both design intent and fabrication standards. When potential design issues are detected, we don’t simply report them — we propose practical, buildable solutions.
STANDARDS AND COMPLIANCE
All steel detailing work, including fabrication and erection drawings, is carried out in accordance with relevant European and international standards to ensure accuracy, clarity, and full coordination. This includes:
Execution & Fabrication
- EN 1090-2 – Execution of steel structures
- EN ISO 13920 – General tolerances for welded constructions
- EN ISO 2553 – Welding symbols on drawings
- EN ISO 5817 – Welding quality levels
Material Standards
- EN 10025 – Hot-rolled structural steel products
- EN 10210 – Hot-finished structural hollow sections
- EN 10219 – Cold-formed welded hollow sections
Corrosion Protection
- DIN EN ISO 12944 – Corrosion protection by protective paint systems
- DIN EN ISO 1461 – Hot-dip galvanizing
- DIN EN ISO 14713-1/-2 – Guidance for galvanizing and durability
Technical Drawings
- EN ISO 128 & EN ISO 129 – General principles of presentation and dimensioning
- EN ISO 5455 & EN ISO 5457 – Drawing scales, sheet sizes, and layout
- EN ISO 7200 – Title blocks and document metadata
Our commitment to these standards ensures that every deliverable is fabrication-ready and meets both European and client-specific quality requirements.
