DESIGN/BUILD

Diamond Precast Stairs manufactures a variety of standard stair treads.  The tools provided on this page are to help you design and choose the correct product for your project.  The customer is responsible for providing shop drawings, custom product designs and/or field measurements.  Diamond Precast does NOT provide these.

Each standard item has it's own dimension, weight, and shop drawing, for you to reference.  All stair treads are manufactured 1/8 " shy on each side (1/4" shy total length) to allow for margin of error on stringer fabrication.
