STAIRTEC SR is a linear profile, which works very well as stair nosing for steps and finishing trim for all exposed corners, thanks to its quick and practical application covering perfectly well the tile gap over the step while protecting the edge. The SR trim has an extended vertical edge which serves to better cover and protect the joining surfaces or paint finishing, avoiding future fissuring. Its particular section design makes it suitable to match two different floor thicknesses for example 10 and 12,5 mm with the same reversible profile. Vertical anchorage with dovetail internal cavity groove. Patented system.
