Stairway Handrail

[Joe.Carrick]

I have a need for a handrail on some exterior stairways serving decks that have a railing build from composite deck materials ( similar to trex ). None of the manufacturers make a handrail that conforms to code (1-1/4" to 2" diameter). In addition, depending on the span, strength could be a problem.

Could I use a trex 2x4 or 2x6 on edge and mill the top to a 1-1/2" round (with a finger recess on the back side. Would that conform to code?

The only other option I can think of would be to have a pipe railing made and painted or powder-coated.

BTW, I've noticed a lot of deck stairs that just use the deck guardrails as a handrail. IOW, a 2x4 or similar flat and no separate handrail. Is this really legal?

In my case, I don't need an actual guardrail becasue the stairs are at or just slightly above grade.

Joe.Carrick,

This is what's legal,

A 2x4 or 2x4 flat, or on edge does not constitute a proper handrail according to the deck building code.

***Must be between 1.5” to 2” in either width or thickness***

***Handrail must be at least 1.5” away from wall and its outside edge not more than 4” from wall***

At least one handrail required if stairs are less than 43” wide
At least two handrails required is stairs are 43” or greater
No handrail required for deck stairs with 3 risers or less
If more than 3 risers, only one handrail is required (subject to the width requirements above)

Hope this helps!

Since I can't draw it on this forum, I'll try to describe what I want to do.

1. Start with a 2x4 or 2x6 on edge.
2. Round over the top edge with a router so that the corners are 3/4" diameter.
3. Rout a groove (same radius cutter) in the side closest to the wall to complete the form (3/4 circular section).
4. Round over the bottom edge same as the top. Just for appearance.
5. Attach to the wall or posts so there is at least 1-1/2" clearance.

This would not be a "round" (perfectly circular cross section) handrail, but it would be only 1-1/2" wide. The definition you gave seems to indicate this idea is in compliance, but perhaps it means both vertical and horizontal dimensions have to be in the specified range. I guess the only choice is to check with my building department.

What you describe meets code here; I've used that type of railing several times on my own stairs. As you say, best to check with local building official to be sure.
