Diamond Concrete Products specializes in the design and manufacture of a wide range of standard and custom precast stair treads, as well as other precast items, including wheel stops, window sills, landings and countertops.  We are able to fulfill custom orders and to ship all over the United States.

Our stair treads include open riser, closed riser, half-riser stair treads, cantilever and spiral steps.  Our innovative, lightweight and easy-to-install ZIP stair treads are the latest alternative to messy, pour-in-place steel pan stair treads.

We offer our precast stairs in a wide variety of colors and finishes, including broomed, smooth trowel, exposed aggregate, sandblasted and polished concrete finishes.  We also offer custom options such as ADA-compliant 2” exposed aggregate strip on a broomed finish, glow-in-the-dark nosing strips, and aluminum safety nosings.
