Steel detailing and drafting services

A small senior team, backed by detailers we've worked with for years. From concept and design to the shop-ready fabrication package, to Australian Standards, by engineers who have worked on the tools.

Drafting & design

From a sketch on the back of an envelope to the shop-ready fabrication package.

Structural drafting & steel detailing

3D models and detailed drawings for beams, columns, bracing, stairs, walkways and platforms. We model first, resolve the connections, then produce the drawing set.

  • 3D structural modelling
  • Connection detailing
  • General arrangement (GA) drawings
  • Marking plans
  • Bill of materials (BOM)
  • Library of standard Australian steel profiles

Shop & fabrication drawings

The complete shop-ready package: members and assemblies detailed, marked and listed, so the workshop has fewer questions back to the office.

  • Single-part & assembly drawings
  • Marking plans
  • Bolt lists & BOM
  • DXF for laser cutting
  • Cut-length drawings for profiles
  • STEP files for CNC cutting
  • Weld details and preparation

Mechanical design

Equipment, conveyors, attachments, frames and access systems. Where a design needs validating, it goes through analysis before it reaches production.

  • Equipment & machinery design
  • Conveyors, chutes and hoppers
  • Attachments and custom frames
  • Design calculations and documentation

FEA — finite element analysis

Stress, load and deflection analysis on new or modified designs. The cheapest place to find a problem is on screen, before steel is cut.

  • Static stress & deflection analysis
  • Load case modelling
  • Design validation before fabrication
  • Reporting suitable for engineer review

Sheet metal drafting & flat patterns

Perforated panels, chutes, enclosures, cladding and custom sheet components. Developed flat patterns as DXF for the laser, with material, thickness and K-factor accounted for.

  • Flat pattern development
  • DXF files for laser cutting
  • Bend allowances and K-factor
  • Bend maps
  • Perforated panels & cladding
  • Enclosures, chutes and hoppers
  • Fabrication drawings for sheet components

Stairs, ladders, walkways & access platforms (AS 1657)

Access steelwork detailed to AS 1657 — the Australian Standard for fixed platforms, walkways, stairways and ladders. We work to it regularly.

  • Fixed stairs & stringers
  • Ladders and cages
  • Walkways & elevated platforms
  • Handrails, balustrades & guardrails
  • Grating and checker plate details
  • Detailed to AS 1657 requirements

Balustrades & handrails for civil buildings

Balustrades, handrails and guarding for buildings and public spaces — connections, fixings and infill panels resolved on the model before anything is cut.

  • Balustrade and handrail detailing
  • Glass-panel balustrades and their fittings
  • Post, wall and floor fixing details
  • Setting-out and connection drawings

Structures for road and rail infrastructure

Gantries, supports, walkways, platforms and equipment structures for road and rail, detailed to the head contractor's drawing standards.

  • Gantries
  • Walkways and access platforms
  • Equipment supports and frames
  • Connection detailing and marking plans

Product development & R&D

Taking an invention from concept through experimental runs to mass production. These are long programmes — typically six months to two years.

  • Concept development and feasibility
  • Design calculations and analysis
  • Prototype and experimental-run drawings
  • Revisions after testing
  • Production drawing set for volume manufacture

Drawings for approval

Send the scope through Aconex or any file link; we produce a set built to head-contractor expectations, raising RFIs where information is incomplete rather than guessing.

  • Approval / IFA drawing sets
  • RFI preparation and tracking
  • Amendments per engineer or client mark-ups
  • Documents received via Aconex or any link

Manufacturing

Manufacturing through our established overseas partner, with priority production capacity — from your approved drawings, or from drawings we produce. Won a contract with no production base? We supply drawings and manufacturing; you install.

Manufacturing & steel detailing outsourcing

Manufacturing through our partner facility, from your approved drawings or from drawings we produce. Production is checked by the factory's QC department against our own QA checklist; every job is quoted individually.

Mill test reports (mechanical properties, chemical composition) are supplied. Independent Australian materials certification is arranged where a project requires it — generally public structures under crowd loads, generally not decorative work.

Detailing capacity when your own board is full: you keep the client relationship, we absorb the peak. We work weekends and holidays, and depending on urgency we run nearly around the clock; the hourly rate stays flat, with no per-tonne surprises.

  • Manufacture from your approved drawings
  • Design and manufacture from an idea
  • Cutting and welding of steel structures
  • Priority production capacity with our partner
  • Overflow detailing for busy periods
  • Full project detailing on subcontract
  • Flat hourly rate
  • Weekend and holiday coverage
  • One trial job of agreed scope, subject to availability
