stainless steel railing details :1. Handrail clearance

The distance between the wall and handrail gripping surface is also governed by local code with the most common requirement being 1½" (38 mm) minimum. The National Fire Protection Agency (NFPA) requires that the distance between the wall and handrail be a minimum of 2¼" (57 mm).

2. Handrail strength

Handrails and railings are to support a continuous load of 50 plf(75 kg-m) or a concentrated load of 200 pounds (90 kg). While most steel and aluminum members are adequate to accommodate those loads, decorative wood balusters generally fail under the required loads.

3. Handrail dimensions

Various model codes—The International Code Council (ICC) and National Fire Protection Association (NFPA)—and accessibility standards—ANSI A117.1 and the Americans With Disabilities Act Standards for Accessible Design (ADA SAD)—refer to handrail dimensions. Current versions of these codes and standards now agree that handrail is defined as either a circular cross section with an outside diameter of 1¼" (32 mm) minimum and 2" (51 mm) maximum or a non-circular cross section with a perimeter dimension of 4" (100 mm) minimum and 6¼" (160 mm) maximum and a cross section dimension of 2¼" (57 mm) maximum. In addition, the International Residential Code (IRC) includes a definition of a "Type II" handrail that allows for handrail with a perimeter dimension greater than 6¼" (160 mm).

The IRC and residential portion of the 2009 IBC define Type II handrail as follows:

Type II. Handrails with a perimeter greater than 6¼ inches (160 mm) shall provide a graspable finger recess area on both sides of the profile. The finger recess shall begin within a distance of 3/4 inch (19 mm) measured vertically from the tallest portion of the profile and achieve a depth of at least 5/16 inch (8 mm) within 7/8 inch (22 mm) below the widest portion of the profile. This required depth shall continue for at least 3/8 inch (10mm) to a level that is not less than 1¾ inches (45 mm) below the tallest portion of the profile. The minimum width of the handrail above the recess shall be 1¼ inches (32 mm) to a maximum of 2¾ inches (70 mm). Edges shall have a minimum radius of 0.01 inch

 Handrails are located at a height between 34" (864 mm) and 38" (965 mm). In areas where children are the principal users of a building or facility, the 2004 ADAAG recommends that a second set of handrails at a maximum height of 28" (711 mm) measured to the top of the gripping surface from the ramp surface or stair nosing can assist in preventing accidents
