Normally the sidewalls of a staircase is made out of Steel + plywood + mdf/ finish. This is labor intensive, heavy on site and takes time.
by using a KQ panel you do not need steel construction and are able to apply finish/ of immediately. Easier to doe some machining on site if needed
saving labor, time and less steel
Kerto-Q 69/75mm side walls
