Our Detectable Warning Panels come in many different sizes, colors and types. Detectable Warning Panels are made of several different types of materials, and DWP provides every one of them. Also noted as Tactiles for Sale, these ADA Required Detectable Warnings come in Composite, Cast Iron & Concrete detectable Warnings. Concrete detectable warning panels come in typical sizes ranging from 1’x1’ to 2’x 2’, as well as a range of thicknesses from 1.5 inches to 4 inches thick.

The ADA Detectable Warning Federal Mandate was instituted back in 1991, requiring Only Transit companies like; subways, bus stops & other types of railway transportation, to comply. There was a relief for all other applications until 2001, when the mandate applied to ALL new wheelchair ramp installations and areas with no tactile warning present for warning. (Tactiles up to this point were typically the curb that is stepped off between vehicular areas & pedestrian.)

Without the curb warning in place, a visually impaired person would not know that they are passing from a safe Pedestrian area to a dangerous Vehicular area. Now with the domed warnings in place, and the agency for the visually impaired educating the people this was created for, a Clear warning is in place, and tragedies can be avoided.

The most familiar place that these tactiles are found, is along the edges of railways. As noted above, Train stations, Subways and other rail forms of mass transit, have been complying with this mandate since 2001. The public will also be familiar with these detectable Warning panels in these areas because they are often scene in the background of movies, that are shot in subway locations. Once you read this, I am sure you will start to notice them everywhere you go, and in every movie that shows them.

Some people ask what the colors are important and have restrictions in the mandate, if they are intended for people who can’t see the color. In the beginning the colors were mandated as a percentage of color contrast between the Detectable Warning & the materials It is set In or On. Now they merely require light on dark, or vice versa. The REASON being; the domes can become a trip hazard for sighted people. The color contrast alerts sighted people, of the presence of the cast iron detectable warning - composite detectable warning - concrete detectable warning or any other type of Tactile warning being used, resulting in risk of tripping over them, from lack of vivid visual presence.

ALL IN ALL the detectable warning mandate protects the visually impaired, while still making sure not to cause and alternate problem for sighted people. Now that you know, look for these detectable warning panels along your travels. Look and try to figure out if they are a cast iron detectable warning - composite detectable warning - concrete detectable warning or any other type of Tactile warning.
