Standard Construction Staircase
A standard construction staircase has a closed stringer and closed riser. It is constructed using wedges and glue blocks, this is the most cost-effective way to manufacture a staircase. Wedges and glue blocks are used to hold the stairs together. However, the underside of the stairs will need to be covered in order to hide the wedges.
Open Riser Construction
Mini open riser
Risers left partially open with a gap to ensure they still meet building regulations. The remainder of the riser is closed off using a timber riser. Thicker threads are required to compensate for the lack of wedges and glue blocks. Top Riser is still closed off to cover the joist.
Open riser with bars
No timber riser at all, instead a 19mm diameter metal bar is used, either stainless steel or brushed aluminum. Thicker treads and required to compensate for the lack of wedges and glue blocks. Top Riser is still closed off to cover the joist.
Exposed back stairs
We construct the stairs differently to normal so that the underside does not need to be covered. This is more labor-intensive and thicker materials have to be used which increases the cost of the stairs.
Cut string stairs
The top section of the string is cut away and a wider section is below the treads. This allows a great deal of flexibility to create either traditional or contemporary stairs.
