Projolly Square is a square corner bead profile in polished, super polished, satin finish stainless steel AISI 304/1.4301-V2A that can be applied on external corners  of coverings. It can be used to close the perimeter of coverings, like a connection profile between step tread and riser of stairs coated with ceramic and natural stone tiles, and also as separation profile for floor and wall coverings. Its particular section, the availability in three different finishes and special pieces such as internal and external corners, end caps and joints make Projolly Square a much sought-after profile that allows a workmanlike application even in environments subject to high mechanical stresses.
