Abstract
A wheelchair ramp system includes a ramp constructed from at least one structural insulated panel (SIP) having a foam core sandwiched between two structural facing panels such as oriented strand board (OSB). An outdoor exterior coating such as polyaspartic coating covers the SIP panel for allowing the SIP panel to be resistant to outdoor elements. At least one guardrail or handrail is secured to the side of the SIP for providing a safety barrier to persons using the ramp system.
