helical staircase / stainless steel frame / wooden steps / without risers
stainless steel frame
The Madden cantilever helical staircase is adaptable for many environments. The secret to this staircase’s success is in hidden cantilever metalwork. The first fix involved embedding a structural mild steel stringer into the wall with protruding, welded cantilever steel channels. The stringer was then sandwiched behind a supporting wall and plastered, completely hiding the stringer. Custom made timber box treads with inlaid satin brushed stainless steel tread detail were then sleeved over the channels. The helical stair was finished off by affixing curved sculptural glass balustrade panels to the treads and a complementary mirror polished stainless steel slotted handrail with a custom made newel post.
