MAH Steel - Services

3D Steel Modelling

Using Tekla Structures, we create accurate 3D models, shop drawings, and fabrication data for structural steel projects of all sizes.

Our detailing services produce clear, build-ready information that supports accurate fabrication and smooth installation on site.

What we provide:

  • General arrangement (GA) drawings
  • Detailed shop drawings
  • Steel erection drawings
  • Individual part drawings
  • CNC files for automated fabrication
  • 3D models for visualisation and coordination

We work closely with engineers and architects to ensure all drawings are accurate, approved, and ready for manufacture.

Modelling & coordination

3D modelling allows us to detect clashes, refine connections, and resolve issues before structural steel fabrication begins. This reduces errors on site and helps keep your project on schedule.

We coordinate directly with your project team, chasing approvals where needed and making sure information is clear and complete before work moves forward.

Accuracy & efficiency

Our detailing process is designed to support efficient fabrication. By linking directly to CNC machinery, we minimise manual input and reduce the risk of errors.

We also use material planning tools to optimise steel usage, helping reduce waste and control project costs.

Why it matters

Accurate detailing means fewer delays, fewer on-site issues, and a smoother build overall. It gives you confidence that every component will fit as intended.

If you need steel detailing or 3D modelling for your project, get in touch with MAH Steel. We’ll review your drawings, prepare the necessary information, and support your project through to fabrication and installation.


3D Steel Modelling & Detailing Questions & Answers

Here you’ll find information about our 3D steel modelling and detailing services, including how projects are developed from concept through to fabrication-ready drawings. This section addresses common questions around modelling accuracy, coordination, workflows, and how detailed steel models support efficient manufacturing and on-site assembly.

See all our FAQs

What is 3D steel modelling and detailing used for in structural steelwork?

3D steel modelling and detailing is used to create accurate digital representations of structural steel frameworks before fabrication begins. It helps visualise the full structure, identify potential clashes, and ensure every component is precisely designed and manufactured to fit on site.


What is the difference between CAD drawings and 3D steel modelling?

CAD drawings are typically 2D technical drawings that show individual views, dimensions, and layouts of a structure. 3D steel modelling, on the other hand, builds a complete digital model of the structure in three dimensions, allowing the design to be viewed as a whole. Both are used in structural steelwork depending on project requirements and level of detail needed.


Why is steel detailing important before fabrication begins?

Steel detailing ensures that every component of a structure is accurately designed before fabrication starts. It reduces the risk of errors, improves on-site installation efficiency, and helps ensure all steel elements fit together correctly according to engineering and architectural requirements.
