When designing a guardrail system, an architect or consulting engineer will first create a schematic drawing that details the general size, length, and location of the guardrail system. This document also shows specific requirements for the structural design, such as members sizes, attachment locations, and weight capacities. A design must be compliant with ADA standards and code requirements, which will determine how the guardrail system will be constructed. Fortunately, there are many resources to help you make an informed decision.
The guardrail system itself must meet certain requirements, including its strength and durability. It must be able to support at least 200 pounds (890 newtons) applied within two inches of its top edge. Furthermore, the guardrail must not deflect below the level of walking/working surfaces. OSHA has additional requirements regarding the strength of the guardrail system, which include:
The top and midrails of the guardrail system must be made from smooth-surfaced materials, which prevents clothing from getting caught on the rails. The ends of the guardrail should not overhang the scaffold’s supports. Aside from its strength and appearance, the top and midrails must have a smooth surface to prevent punctures and snagging of clothing. The entire perimeter of the guardrail system should be at least 24″ wide and 48″ high.
The top rail of structural steel angles must be able to withstand at least 50 pounds per linear foot. The top rail of a steel angle must have the outer face of the vertical leg adjacent to normal contact with the bottom of the guardrail. As a final note, a guardrail must be installed in a location that has a code for railings. The California regulations for roof fall protection systems and guardrails are more stringent than federal ones.

Finally, paint or stain the rail to protect it from the elements.
How do you make a simple wood handrail?
I would plan out the handrail on paper or in a computer program first. Once you have the dimensions and design, you can begin measuring and cutting the wood to size. I would then recommend sanding the wood and applying a finish before assembly. Once everything is ready, you can begin attaching the handrail to the wall or staircase using screws or bolts.

For that reason, 2×6 framing lumber is the top choice for building decks (enclosed and open). But be certain when you purchase 2×6 lumber that the size is nominally 2 inches by 6 inches. … If a 2×4 is actually only 1 1/2 inches (3.8 cm) by 3 1/2 inches (8.9 cm), then the 2×6 would be only 1 1/2 inches by 5 1/2 inches (3.8 cm x 13.9 cm)!
