What is the standard height of an outdoor stair railing?

What is a handrail perimeter?

Handrail gripping surfaces with a non-circular cross section shall have a perimeter dimension of 4 inches (100 mm) minimum and 6″ maximum, and a cross-section dimension of 2-1/4″ (57mm) maximum.This applies to sections with a perimeter greater than 6-3/4″.

How is railing length calculated?

Overall length is determined by measuring the horizontal distance from the edge of the nosing on the first tread at the bottom of the staircase to the edge of the nosing on the floor/landing at the top of the staircase. The final measurement to acquire is the distance along the nosing.

What is the difference between a guardrail and a handrail?

OSHA and many building codes use the term “guardrail” to refer to fall protection for raised platforms and stairways, but the industrial safety industry uses the more specific term “handrail,” with “guardrail” used only to refer heavy-duty beams of formed steel.
