Common questions
What is a tactile walking surface indicator?
A TWSI is a surface with raised truncated domes installed at the boundary between a pedestrian route and a roadway, detectable underfoot and by a long cane. They are specified at curb ramps and depressed sidewalk edges. The governing requirement comes from the municipal or provincial accessibility standard for the project. Confirm the applicable detail before ordering.
What finishes are available?
The catalog lists raw cast iron plus powder coated yellow, brick red and asphalt black. The required colour is set by the municipal standard, which varies.
Do you supply radius plates for curb returns?
Yes. Radius plates are stocked in several radii and each is listed by its radius in the product name.
