• A flier is an ordinary step of uniform width and rectangular shapes in plan.
• A bull nose step, generally provided at the bottom of the flight, projects in front of the newel post. Its end near the newel forms the quadrant of a circle
• A round ended step is similar to a bull nose step except that it has a semi – circular end which projects out from the stringer
• A splayed step is also provided at the beginning of the flight, with its end, near the newel post.
• A commode step, has curved tread and riser.
• Dancing or balancing steps are the winders which do not radiate from a common centre.
• Winders are tapering steps, such as those which radiate from a point usually situated at the centre of a newel
