Tactile Warning System 

Detectable warning surfaces play an important role in ensuring the safety of public spaces, especially for individuals with visual impairments. These surfaces consist of a combination of wayfinding bar tiles and truncated domes, which are aligned according to ADA guidelines. The truncated domes are designed to serve as detectable warnings to alert all persons when they approach the edge of a path. The truncated domes' specific dimensions are crucial to their effectiveness as a tactile walking surface indicator (TWSI). The base diameter of each dome must be between 23 mm (0.9 in) to 36 mm (1.4 in), while the top diameter must be at least 50 percent of the base diameter to a maximum of 65 percent of the base diameter. The height of each dome must be precisely 5 mm (0.2 in). Detectable warning pads are commonly used in transit stations and pedestrian crosswalks to alert individuals when they reach an unsafe edge. They are designed to increase the safety of public spaces by providing a tactile and audible cue for approaching hazards. The sound reflection element of each ADA tile and ADA dome helps individuals who use guidance canes to navigate the space unaided. The wayfinding bar tiles that are used in conjunction with the truncated domes, provide directional guidance to individuals, making it easier to navigate through public spaces. Our expertly engineered truncated domes create the ultimate solution in TWSIs. The products are manufactured using high-quality materials to ensure their durability and longevity. We offer a range of dome sizes and colors to suit different applications, making it easier to customize the product to meet specific project requirements. Overall, detectable warning surfaces provide a vital function in ensuring the safety and accessibility of public spaces. By providing tactile and audible cues for approaching hazards, they allow individuals of all abilities to enjoy public spaces without fear of navigating unsafe edges or paths.
