Guidelines The use of very large aggregate in the concrete mix may make placement of the safety nosing difficult. Safety nosing placement may be difficult in concrete with very low slump. Place concrete into the stair forms or steel pans as quickly as possible; schedule pour so as to install the metal safety nosings quickly before the initial set of concrete occurs. Puddle the concrete, tamp the safety nosings to insure proper concrete formation around the anchors. Order nosings or treads well in advance of the pour or installation date. Close stairway after pour; permit no use for 24 hours. LENGTHS: Lengths are to order up to 12’0” maximum in one piece. Lengths over maximum will be made in equal section No. Wt/Lf (lbs) WP 231BF 1.17
