Creating a “C“ Channel Stair for Revit® Architecture 2014 and up

Hagerman & Company

There are a variety of variables available for stairs. In this article we will look at a specific group of variables within the stair family.

The Support group of variables will allow us to change the type of support, stringer type to a C Channel profile and adjust the position of the stringers. This can be applied and used for both Straight and U shaped stairs.

Getting Started:

Start a new project with the Architectural template provided with the install of your software.

Start the “Stair by component” and duplicate the 7” Max 11” Tread stair. Name the duplicate stair Steel Stair.

Alternatively: Expand Families in the Project browser, Expand Assembled Stairs> Select 7” Max 11” Tread , Right Click and choose Duplicate> Rename stair to Steel Stair.

Place the Steel Stair with no Railing.Finish Stair
Revit tip

I recommend initially placing the stair with no rail until you get
the stair set up the way you want. Later you can create the stair with
the railing.


Look at stair Type Properties

Note Supports:

Right Support |Stringer Closed and

Right Support Type | Stringer-2” Width

Same is applied to the Left supports

Expand Right Support and look at options (close)

Revit tip

Since there is only one “Right Support Type” defined
in the Template, select the button to the far to open the default
“Right Support Type”, Stringer-2” Width.
Revit tip

In Type Properties you should now have the Family:

System Family: Stringer and Type: Stringer-2” Width.

Revit tip

In the Type Properties dialog box, Duplicate the Stringer type and
name it “C Channel”.

Expand the “Default” Section Profile under Dimensions.

There is a Default C-Channel –Profile: C9x15
preloaded into the Architectural Template.

Note for this exercise we will us the Preloaded default. If you want
to use a different section profile, load it before creating additional
stair types.

See steps at the end of document.

Expand the “Section Profile” again, this time select the C Channel

Select Apply

Select Ok Twice

Note the direction and placement of the Channel. If it needs to be
flipped or vertical position adjusted:

Select “Flip Section Profile” and adjust “Structural Depth On Run” as

Revit tip

In the Type Properties apply the “C Channel” Stringer to the Left
side of the stair.

There is also an option for a Middle stringer.

Option: Removing the Riser for the Steel Stair

Select the Stair > Select “Edit Type” to open Type Properties>

Select “Run Type” under Construction.

Revit tip

In Type Properties for the Run Type> Duplicate the
default “2” Tread 1” Nosing 1/4 “ Riser” and name it

2” Tread 1” Nosing No Riser”.

Revit tip

Deselect the “Riser” check box, select OK.
Revit tip

Verify that the 2” Tread 1” Nosing No

Riser. Is applied to the Steel Stair Type.

Select OK, Twice

U Shaped Stair based on adjustments made during the Exercise

Individual Members surrounding the landing cannot have their
individual type changed.

The Landing type is control by the setting of the Left and Right
Support Types defined on the Steel Stair Type Properties.
