In respect to this, what is the code for hand railing?On a stair, since handrail must be between 34″ and 38″, the handrail and the top of the guard can be one and the same. In commercial applications, the IBC requires a minimum height of 42″. On stairs, once there is a 30″ drop, a handrail will be required and placed between 34″ and 38″ above the nosing.One may also ask, who invented the handrail? Rudolf Wittkower withheld judgement as to the inventor of the baluster and credited Giuliano da Sangallo with using it consistently as early as the balustrade on the terrace and stairs at the Medici villa at Poggio a Caiano (c 1480), and used balustrades in his reconstructions of antique structures. Likewise, are handrails standard? Handrails must be between 30 and 38 inches as measured from the leading edge of the stair tread. Top rail may also serve as handrail if height of the system is between 36 and 38 inches.What is the code for railing spacing?Balusters, the vertical guards that support the handrail, must be installed close enough that the space between them is no greater than 4 inches. Most city inspectors carry a 4-inch ball with them to test the spacing. Installed balusters should withstand 50 lbs. of pressure exerted over a 1-square-foot area.
