Spiral Tread K

F170000100

Steel 240 YP

PcP. Spiral treads type K, 20° and 24° are our standard spiral treads. The treads are universal treads which means that they may be applied in both right-hand and left-hand rotation spiral stairways. The pattern is made with 14 mm dia. punched holes and 9 mm dia. drainage holes, harmonically distributed over the angle surface. The first row of holes is 300 mm from the spiral centre. The spiral treads are supplied self colour and without steel edge in external and internal curved edges so that they are easy to further process and adjust into the design of the individual stairway.
