Ramp
Definition
A ramp is an inclined plane or sloped pathway that connects two different levels, providing a smooth transition for pedestrians, vehicles, and wheeled equipment. As a critical component of universal design and accessibility, it serves as an alternative to stairs, enabling independent movement for individuals with mobility challenges, such as wheelchair users or those with strollers. Ramps can be constructed from various materials like concrete, metal, or wood and are designed with specific gradient requirements, landings, and handrails to ensure safety and ease of use in both interior and exterior environments.
Structural & construction notes
Common types of ramps include straight run systems for direct access, switchback or 180-degree turn designs for confined areas, and 90-degree turn configurations. Other variations include curved or spiral ramps for aesthetic transitions, portable folding models for temporary use, and specialized curb ramps like built-up, flared, parallel, or returned styles. Common materials include wood, aluminum, concrete, steel, rubber, and composites. Aluminum and composites offer high durability with low maintenance at a mid-to-high upfront cost. Concrete provides maximum durability for permanent use but is the most expensive and labor-intensive to install. Wood and rubber are the most affordable options but require more frequent maintenance or offer limited lifespans compared to metal and masonry.
