How to Connect Stair Stringers to Concrete How to Connect Stair Stringers to Concrete

What You'll Need
Metal hangers or straps
Stair stringers
Angle irons or bolts

Stair stringers should be connected to the surface below in order to insure that you have a sturday installation. Stair stringers are an important part of the construction of your stairway. These parts are responsible for managing the bulk of the weight that occurs on the stair steps. You can connect stair stringers to a wood subfloor, and to concrete subfloors. Below is a step by step instruction on how to properly connect the stair stringers to concrete.

Step 1 - Understand Stringers and Stairway Construction

The stringers must be constructed so that they are strong enough to support the heavy weight of people walking up and down the stair treads. The steps are called treads. The riser is the up and down vertical piece that is seen in between each tread or step. It is usually the thing you may kick when you walk up the stairs.

Step 2 - Connect the Stringers to the Skirt

Before you connect the stringers to the concrete, you will need to attach them to the skirt of the stair way. Attach the stringers using metal hangers or framing straps. Use heavy screws in this attachment.

Step 3 - Attach Stringers to Concrete

Concrete is either the base underneath the stringer or it may also be a concrete footing that you have poured to provide extra support and strength to your stairway. Using heavy bolts, attach the stringers to the concrete. You will want to add several bolts from the stringer to the concrete.

In order to attach the bolts correctly, drill holes into the concrete. Use a specific drill that will drill a neat hole into the concrete base. Once the hole is drilled, you can then attach the stringers with the bolts.
