Stairs and Railings

Design of complex structures such as straight and spiral stairs, railings, cage ladders, etc



Stairs - Quick and easy

Once the user selects 2 points, the stair with its stringer and treads (including connection to the stringer) is created.

The tread distances are calculated using a standard formula for determining the ergonomic height and length of the step.

The stair can be modified using:

  • Numerous profile types for stringers (I, U, Flat, Tubes, User profile)
  • Various connection types between the treads and the stringers (directly welded or bolted, with a welded or bolted angle)
  • Lower and upper landing (with plate or grate cover)

Any tread type can be created with Autodesk Advance Steel.

  • A large library of tread types is available (folded plate, grate, wood, etc.)
  • You can also define your own tread type that can be stored in the library for future use
  • Optionally, different top and bottom treads can be defined

Instant railings

GRAITEC Autodesk Advance Steel | Stairs and Railings

Creation of railings on the stair stringers is also simple!
Once the stringers (horizontal or sloped) are selected, the railings are created using the user defined start and end points.

Railings of any type can then be modified. Features include:

  • Several profile types for posts, handrail (top and middle) and kickrail (I, U, Flat, Tubes, User Profile, etc)
  • Controlled positioning of posts, top handrail, middle handrail and kickrail: side or top of the stringer
  • Connection between posts and handrail: cuts, welds, chamfers, etc
  • Connection between posts and stringers: welds, bolted or welded plate
  • Vertical filling of intermediate bars can be added
  • Preferred settings can be stored in the library

If the stair length and width are modified the railing is automatically updated!
In addition, you can create a railing on different beams!

Spiral stairs

A spiral stair can be created in 4 steps: position selection in the structure, central post definition (circular or square tube), setting of treads' geometric properties (folded plates, welded plates, wood treads, etc.), establishing tread-central post and post-handrail connections and railings.

Using the Autodesk Advance Steel advanced tools, with a few clicks defining the height, the tread width and direction, the entire stair can be created. Autodesk Advance Steel: Stairs - Spiral stairs Various options are available:

  • A large library of tread types (folded plate, grate, wood, etc.), same as for the straight stair
  • Treads can be welded to the central post or connected by a profile or a bolted plate
  • The outer edge of the treads can be straight or can follow the stringer shape
  • Stairs with no central post, where a flat central stringer supports the treads

Cage ladders

GRAITEC Autodesk Advance Steel | Stairs and Railings

All elements of a cage ladder are inserted by two points defining the height. The number of rungs can be defined or calculated according to the distance between the rungs. The user can modify then the shape and the size of the elements.

  • Various sections library for the rungs and stringers
  • Different options for the wall connection: folded plates, plates, sections
  • Several cage types with different brace shapes and bands displacement
  • Several ladder exit types

Easy to customize

Stairs and railings can be customized through the Properties dialog box.

The tabs of the Properties dialog box are grouped in logical categories to simplify the use of this powerful feature.
The user can modify the parameters (dimensions, treads types, connection types, etc.) to get the required structure. All modifications are visible in the model as they happen.

The entire structure can be stored in the library for future projects.

Autodesk Advance Steel is based on the AutoCAD® platform, hence tools such as 3D orbit and the various shade modes can be applied for a more realistic display.

In addition, the Render function from AutoCAD® can be used to assign a specific material to your structure (e.g., bricks on the wall) as shown in the picture.

Automatic drawings

Autodesk Advance Steel offers many templates for stairs & railings workshop drawings.

Once the stair is modeled, the user may select a template for the workshop drawing. Autodesk Advance Steel then creates all the necessary documents (including NC files) for the stair fabrication. The drawings are automatically labeled and dimensioned. The user can customize the drawing layout using the Drawing Style Manager.
