On Concrete Slab Style
A landing to landing setup is also available. This type of stringer is fabricated to order. Supagal finished stringers are available within 24 hours and Hot Dip Galvanized require a few more days. (We recommend that this type of stringer be purchased prior to erecting the landing to ensure an exact fit).

How do you calculate the steps you need on your stringer?

Simply measure the height from the top of the landing to the ground directly below, divide this length by 175 rounding to the nearest whole number and deduct 1 for the top landing.

Example: Height = 2415 divided by 175 = 13.8 (14) less 1 = 13 Step.
