Your light steel building, from plan to machine, in one model.

CAD/CAM software for light steel, prefab, modular and hangar manufacturers. It builds panels and the roof from your DXF plan and writes every profile to your rollforming machine's file.

One house, two ways of working

On the way from plan to machine, every manual hand-off is a step where an error can reach production.

Without QSteelCAD

Scattered files, manual hand-offs

PlanRedrawn panel by panel
RoofTrusses drawn one by one
Profile listCompiled by hand
Holes and notchesDimensions typed by hand
ChecksErrors may surface in production
Presentation and takeoffPrepared in separate programs

With QSteelCAD

One model, checked output

PlanDXF is read, walls and openings recognised
RoofTrusses and panels built from one window
Profile listComes from the same model
Holes and notchesWritten to each profile from the model
ChecksChecked before export

How to choose light gauge steel software: 10 questions before you buy

Production and erection

What is the difference between general CAD and light gauge steel software?

Regulations

Turkey's light steel regulation takes effect on 1 January 2027: what changes?

Bracing systems

Bracing systems in light steel: a guide to X, K, V and sheathed panels

Regulations

Bracing systems

What is K-bracing? Compression, node and end bearing in profile bracing

Regulations

Light steel material rules 2027: 250 MPa, the DX grade ban and screw requirements

Load path and connections

What is the difference between a hold-down and a shear anchor?

Regulations

TBDY 2018 Chapter 10: braced panel rules, clause by clause

Regulations

Light steel floor rules 2027: deflection table, 8 Hz and web stiffeners

Load path and connections

Floor and roof diaphragms: who delivers the load to the braced wall?

Regulations

Fire design in light steel: what does Section 11 of the regulation require?

Load path and connections

How doors, windows and services affect a braced panel

Bracing systems

Bracing, bridging, diaphragm, temporary prop: four look-alike duties

Regulations

Modular and hybrid light steel buildings: the 14 metre limit and the 10% rule

Production and erection

A temporary prop is not permanent bracing: how to keep the frame stable during erection

Production and erection

Strap tension and tensioners: why does slack bracing cause problems?

Production and erection

Why is saving bracing in CAD as a line between two points not enough?

All contact channels
Which files can I open?

DXF floor plans, including binary DXF, MLINE, ELLIPSE, SPLINE and dynamic blocks. The program does not read DWG; save the file as DXF in AutoCAD and open it.

Which rollforming machines does it work with?

The program writes production files for rollforming lines that read .bde lines. Rollform-80, 90, 140, 200 and 300 profiles come ready, and stations switch on or off per profile.

Let's check your machine's line format together in a meeting.

Does it do structural calculations?

QSteelCAD runs production checks: error check, minimum length, clashes and model audit. It also flags joints that need an engineer's approval.

Structural adequacy, including bracing and section choices, is for the project engineer to approve.

Do I need a separate program for presentations?

Renders with cladding, roof cover, rooms and furniture come from the same model, and quantities and cost export as CSV. Save images as PNG, JPG or BMP and the model as GLB.

How does licensing work?

The licence is activated online and tied to one computer. While the program is open the licence is checked regularly; it keeps running for 7 days without reaching the server.

Get in touch for packages and pricing.

Do updates affect my projects?

Updates keep your licence, settings and projects. Structures in older projects are recognised by newer versions, for example older double-collar K braces.

Which Windows versions does it run on, and how long is setup?

It runs on Windows 10 and Windows 11. The setup wizard installs everything it needs; setup takes about a minute.
