In ground Foot Style
The inground foot style is the most popular form of stringer. After bolting the top hanger brackets into place, the base of the stringer is simply concreted into a suitable hole in the ground. The leg on the stringer is approximately 350mm long, a cross bar is welded to the bottom of the leg to assist in holding into the concrete footing.

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.
