PROTERMINAL is a L-shaped profile in polished, brushed and varnished aluminium 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 or natural stone tiles and also as separation profile for floor and wall coverings (the varnished only for wall application). Its particular section and the availability in different finishes make PROTERMINAL a much sought-after profile that allows a workmanlike application.
