The advantages of modular aluminum ramps are numerous. The first and most obvious reason is the minimal maintenance that is required to keep the ramps looking good. Wood ramps need constant maintenance to keep them from splitting and pealing. Steel ramps rust very quickly when outside. Aluminum Modular ramps also have a mesh surface that allows snow and ice to fall thought the ramp. This helps in the winter and the ramps are much safer because they are far less slippery than wood. If a wood ramp is built, plywood should never be used as the surface. Plywood is extremely slippery when wet. Another reason aluminum modular ramps are better is their ability to be moved and re-assembled quickly with minimal cost. This is really important if someone is renting or planning to move.
