Handicap ramp slopes are sold by Disability Systems, Inc., according to its official website. The company assists both disabled clients and commercial businesses in ramp selections. Ramps featured by the company are made to meet ADA compliance requirements and are designed for home and office use.
Portable and modular wheelchair ramps are sold by Disability Systems, Inc. along with door openers for residential and commercial properties. The company features a single-fold wheelchair ramp on its site that is manufactured with aircraft-grade aluminum. The portable slope, which can hold up to 600 pounds, is available in lengths from 2 to 8 feet. According to the company's website, ramp widths can be customized.
The U.S. Access Board states that the rise of a ramp slope should be no more than 30 inches or 760 millimeters. The Board, which sets the standards for maneuvering clearances, establishes the speeds for doors and gates used by the handicapped. According to its website, outside landings for ramps should be waterproofed where water collection is a problem.
The ADA National Network notes that ADA compliance must meet with the guidelines established by the 1990 Americans with Disabilities Act. The civil rights law, which prohibits discrimination against the disabled, ensures that handicapped people are given the same opportunities as their nonhandicapped peers.
