Overview

STAIR CASE MARKING

Stairs are an essential part of many construction projects, from decks to interiors. It can seem daunting to think of making your own, but they’re actually made of just three main parts: stringers, treads, and risers. Stringers are diagonal 2 in × 12 in (5.1 cm × 30.5 cm) boards that support people’s weight as they walk up the stairs. Treads are the top baseboards onto which you step, and risers are placed perpendicularly under each tread. Measure and cut the stringers accurately, and the other parts will mostly fall into place.

Applications

Staircase is an important structural part in construction. It allows user to go further floors. Staircase must be constructed in proper way. Otherwise, User can not feel comfortable in using other further floors.

I mean that staircase have certain limitation. What are they?

  • Each flight having Steps not more than 12 nos
  • Riser should not more than 7” and not less than 5”
  • Tread must be not less than 9”.
  • Height of the handrail must be exactly 2’6”.
  • What ever may the number of flight and length of flight, but each flight must have a landing after 12 steps
  • width of staircase must be at least 3’0”  for residence and 4’0” for public.

A stair riser is the vertical space between one step and another. It may be closed or open, depending on the style of the stairs. 

A stair tread is the horizontal part of the step that a person will stand on, and along with the riser, is an integral part of a staircase.
