Coming really handy when renovating, theses transition profiles are conceived to realize a slope of 30 degrees between a ceramic surface and another surface of an inferior level by creating a smooth transition. Also ideal for transitions from ceramic tile coverings to finished surface. An angle of 90 degrees at the end of the slope will allow the meeting with a thinner revetment: like a carpet, a wood floor or a vinyl surface. Natural aluminum has a tendency to become corroded under the effect of humidity and chemical products. That is why you have to evaluate, in a very circumspect way, the place where they will be installed.
