Construction Grade Stairs Details

Sandhills Manufacturing Ltd. is a best-in-class construction grade stair producer.  We go above and beyond in our design, our materials, and our fabrication methods.  See below for just some of the benefits of building with Sandhills.

Below is a demonstration of our Housed Stringer-based design.  Some things to note:

  • Note the upgrade in materials for the housed stringer (3).  Instead of a standard piece of SPF, Ply-Lam is used.  See www.ply-lam.ca for the added benefits of using Ply-Lam instead of plywood.  
  • Each riser is built with a backing piece (5) to give additional support and stiffness, which in turn leaves your customer with less creaking (and you with less complaints or warranty work).
  • The top (2) and bottom (8) risers are upgraded to a full 1" piece of plywood, again providing additional stiffness at the most important points in the staircase.

  1. 1" Plywood Top Nosing Piece
  2. 1" Plywood Top Riser

Below is a demonstration of our Cut-Out Stringer-based design.  Some things to note:
