Wood is a suitable material for building a wheelchair ramp; however, aluminum offers more benefits, explains Ramps.org. Wood ramps are more expensive to build and require regular maintenance. Aluminum ramps last longer, and since they are not installed into the ground, they are easier to remove or adjust.
Wood requires additional treatment to become suitable for an outdoor wheelchair ramp. Regular wood is slippery when wet, so builders must apply non-stick surfaces to wooden wheelchair ramps. Wood should be weatherproofed to prevent rotting. By contrast, aluminum wheelchair ramps come with a non-stick surface already applied, and the metal does not rust or rot.
Removing splinters, repainting the surface, mitigating termite damage and fixing regular wear and tear are additional concerns for wooden wheelchair ramps that do not apply to aluminum ramps.
