Projolly is a rounded bead profile in polished, super polished, sanded and 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 and like a connection profile between step tread and riser of stairs coated with ceramic or natural stone tiles. Its particular section, the availability in three different finishes and special pieces such as internal and external corners, end caps and joints make Projolly a much sought-after profile that allows a workmanlike application even in environments subject to high mechanical stresses.
