Structural Steel Detailing Services

Service Overview

Steel Detailing For Fabricators, Engineers And Plant Builders

Steel detailing turns the engineer's design drawings into what the shop and the site crew need: every member drawn with its cuts, copes, holes and welds; every assembly with its parts and bolts; erection drawings with marks, orientations and sequence. We detail from your design drawings or 3D model, raise RFIs for anything unclear, and check every drawing against the design before it goes to the shop.

Our detailing sits alongside our machinery and fabrication work, so it suits industrial steel — equipment supports, platforms, mezzanines, stair towers, pipe racks, conveyor and chute supports and plant frames — detailed in the same CAD platforms we use for the equipment they carry.

Fabrication (shop) drawings for beams, columns, bracing, plates and built-up members
Assembly and erection drawings with piece marks, orientations and bolt callouts
Connection detailing from the engineer's design: shear, moment and bracing connections
Platforms, stairs, ladders, handrails and grating with anchor and base plate details
Equipment support structures, skids, pipe and conveyor supports, plant frames
Material take-offs, bolt lists, weld maps and NC/DXF plate profiles

What this service is not: We do not perform structural engineering design or connection design calculations; detailing is from your engineer's design, and connection capacities remain the engineer of record's responsibility.

What's Included

Steel Detailing Capabilities

Shop Drawings

Single-part and assembly drawings with cuts, copes, holes, welds, marks and material grades the fabricator needs to cut and weld.

Erection Drawings

Plans, elevations and sections with piece marks, orientations, bolt types and sequence notes for the site crew.

Connection Details

Bolted and welded connections drawn to the engineer's design, with gauges, edge distances and weld sizes checked against the standard.

Platforms & Access Steel

Mezzanines, platforms, stairs, ladders, handrails and grating with base plates and anchors.

Equipment Supports & Skids

Structures that carry machinery, pipework and conveyors, coordinated with the equipment models we design.

Lists & Shop Files

Material take-offs, bolt lists, weld maps and DXF plate profiles for cutting.

What We Need From You

Inputs We Work From

Send whatever you have. We list anything missing or ambiguous in a query sheet and agree it with you before modelling starts — nothing is assumed silently.

Standards & Platforms

Drawn To Your Standard, Delivered In Your CAD

We work to the drawing and design standards your market specifies. Editions below are current as of October 2026.

Standards we apply

AISC conventions (USA) — Detailing practice consistent with AISC specifications; edition confirmed per project with your engineer
AS/NZS 5131:2016 (Amd 1:2020) — Structural steelwork fabrication and erection documentation for Australia and New Zealand
EN 1090 execution conventions (EU/UK) — Detailing aligned to the execution class and documentation your fabricator works to
IS 800 / IS 2062 (India) — Indian structural steel design and material references
AWS A2.4:2020 / ISO 2553:2019 — Weld symbols to the standard your fabricator reads
ASME Y14.5 / ISO GPS — Dimensioning and tolerancing conventions on plates and machined interfaces

Native CAD platforms

You receive editable native files, not just exports. We do not advertise platforms we cannot deliver natively.

How The Work Runs

Our Process For This Service

1

Design review and RFIs

We review the design drawings, raise RFIs for gaps and agree marking, standards and templates; fixed price per structure or tonne.

2

3D model

The structure is modelled with members, connections and hardware so clashes and fit are checked before drawing.

3

Detail drawings

Shop and erection drawings, connection details and lists are produced on your template.

4

Check and issue

An independent check against the design and standard, then issue for approval and for fabrication with revision control.

Worked Example

Engagement Models

Three Ways To Work With Us

Every quote states scope, deliverables, formats, standard, revision rounds and deadline. Prices are quoted per project — in USD, EUR, GBP, AUD or INR.

01

Fixed price per job

Best for defined scopes — a drawing set, a conversion batch, one analysis. You know the total before work starts.

02

Hourly with a cap

For evolving design work where scope is still forming. Hours are logged, reported weekly and never exceed the agreed cap without your sign-off.

03

Dedicated engineer

A named engineer reserved for your work, month by month, on your templates and in your CAD — an extension of your own design office.

Confidentiality & IP

Your Designs Stay Yours

NDA before files

We sign your NDA, or send ours, before a single drawing is shared.

IP assigned to you

Models, drawings and calculations are your property on payment. We keep no rights.

Named engineer

Only the engineers on your job can open your files. You deal with them directly.

Deleted on request

Project data is removed from our systems when you ask, with written confirmation.

Technical FAQ

Questions Engineers Ask Us

Which software do you detail steel in?

SolidWorks, Autodesk Inventor and AutoCAD. We model the structure in 3D, produce shop and erection drawings from the model and export DXF plate profiles and PDF sets.

Do you design the connections?

No. Connection design and capacities remain with your engineer of record. We detail the connections they specify, or apply the standard connections you provide, and raise an RFI where the design is unclear.

Which detailing standards do you follow?

AISC conventions for North America, AS/NZS 5131 for Australia and New Zealand, EN 1090 execution conventions for the EU and UK, and IS 800/IS 2062 references for India — with weld symbols to AWS A2.4 or ISO 2553 as your fabricator reads them.

What kind of steel structures suit you best?

Industrial steel: equipment supports, platforms, mezzanines, stairs and handrails, pipe racks, conveyor and chute supports, skids and plant frames. Large commercial building packages are better served by dedicated building-steel detailers.

How do you handle RFIs and revisions?

RFIs are logged and sent in batches with our recommended resolution; revisions carry clouds and a revision table, and the RFI log and check record are delivered with each issue.

How is steel detailing priced?

Per structure or per tonne after we review the design drawings, with the scope, drawing count and issue dates stated in the quote.

Can you coordinate the steel with equipment you are designing for us?

Yes. Because we design machinery and fabrication in the same CAD, equipment interfaces, anchor layouts and clearances are coordinated in one model.
