Spiralex delivers world-class structural steel detailing, 3D BIM modeling, shop drawings, and CNC NC1 files — engineered to global standards, trusted by fabricators and contractors across 12+ countries.
Who We Are
Spiralex Steel Detailing Services is a specialized engineering firm delivering comprehensive structural steel detailing, BIM modeling, shop drawing production, and fabrication data to clients in the USA, UK, Australia, Canada, UAE, and beyond.
Our in-house team of experienced detailers, modelers, checkers, and project managers uses Tekla Structures and SDS/2 to deliver 2D drawings and 3D models that transition seamlessly from design intent to fabrication and erection. Every file leaves our office having passed a rigorous multi-stage QA review aligned with your project codes and specifications.

What We Do
End-to-end steel detailing solutions — from concept 3D model to fabrication-ready shop drawings, BIM models, and CNC data — delivered with accuracy, speed, and full code compliance.
Complete structural steel detailing for industrial plants, commercial buildings, PEB structures, and infrastructure. Deliverables include anchor bolt plans, framing plans, erection drawings, member and assembly drawings — all code-checked and fabrication-ready.
High-fidelity 3D parametric models using Tekla Structures and SDS/2 — enabling clash detection, automated quantity takeoffs, and seamless coordination between structural, architectural, and MEP disciplines. IFC, CIS/2, and SDNF exports available.
Production-ready shop drawings with detailed connection packages — moment connections, shear tabs, base plates, and gusset plates. We produce erection drawings, assembly drawings, sequence drawings, and embedded plans to your fabrication standards.
Comprehensive rebar detailing and Bar Bending Schedules (BBS) for foundations, slabs, beams, columns, retaining walls, and bridges. Supports ACI, BS 8110, IS 456, and AS 3600 — for pile caps, ground beams, in-situ concrete, and precast elements.
Full pre-engineered building (PEB) and hybrid structure design and detailing — rigid frames, tapered sections, mezzanines, crane girders, wall and roof sheeting. Compliant with AISC, MBMA, AISI, AWS, and LRFD standards, delivered via Tekla.
Complete fabrication data packages — Bill of Materials (BOM), bolt lists, anchor bolt summaries, Advance Material Reports (KISS/XSR), and CNC .nc1 / DSTV / DXF files for automated cutting, drilling, and plate nesting. Integrates with FabTrol and ERP systems.
Ornamental and miscellaneous steel — staircases (straight, curved, spiral), handrails, ladders, grating, platforms, walkways, cable trays, and custom metalwork. We handle complex geometries and bespoke architectural steel elements.
Expert precast concrete panel detailing — wall panels, hollow-core slabs, precast beams, columns, and facades. We coordinate steel embedments, lifting inserts, rebar placement, and connection interfaces, delivering complete form drawings and shop tickets.
Comprehensive joist and deck detailing for all structure sizes — from small commercial buildings to large industrial facilities. We produce deck layout drawings, bundle information, joist erection drawings, joist cut sheets, and complete joist reports, working in close collaboration with structural steel detailing packages to deliver a coordinated fabrication solution.
We manage the complete approval cycle — IFA (Issued for Approval) to IFC (Issued for Construction) — with revision tracking and cloud-marking. Our RFI tracking tools ensure zero delays from missing information, with weekly progress reports and a dedicated single-point-of-contact project manager.
Codes & Standards
Every deliverable from Spiralex is checked against the applicable international standard — ensuring fabricators, engineers, and certifiers accept our drawings without qualification, anywhere in the world.

We invest continuously in upgrading our software so our deliverables stay compatible with the latest fabrication systems, file formats, and BIM workflows your projects demand.
How We Work
A structured, ISO process-driven workflow that eliminates errors, keeps schedules, and delivers fabrication-ready outputs every time.
We receive your design drawings, specifications, and standards. Our project manager reviews scope, assigns a dedicated team, and establishes a milestone schedule aligned with your fabrication timeline.
Our modelers build a complete 3D parametric model with all connections, splices, and embedments — the single source of truth for all downstream drawings, reports, and NC1 data.
A dedicated checker audits the full model — validating connection geometry, checking clashes, verifying material lists, and confirming compliance with AISC, BS, IS, or AUS standards. No drawing leaves without passing this gate.
Fully annotated shop drawings — erection plans, member drawings, assembly drawings, anchor bolt plans — generated directly from the model to eliminate transcription errors and ensure consistency across the package.
Drawings are submitted IFA. Engineer and EOR comments are incorporated promptly using our RFI tracking system. All revisions are cloud-marked and resubmitted within agreed turnaround times.
Approved drawings released IFC alongside BOM, bolt lists, advance material reports, and CNC NC1/DSTV files — giving your fabricators everything needed to go straight to production with zero additional coordination.

Client Feedback
"Spiralex consistently adheres to our project deadlines and ensures all coordination queries are resolved before submitting drawings for approval. Their Tekla models are clean, accurate, and fabrication-ready from day one."
"We engaged Spiralex for a complex multi-storey composite building in Dubai. Their BIM coordination workflow caught several clashes early that would have been expensive on site. Excellent value and a highly professional team."
"The major reason I recommend Spiralex is the peace of mind that comes from knowing I won't need to double-check their work. Their internal QA is thorough and the NC1 data integrates perfectly with our CNC cutting machines."
