* Plastic: This is a common material, often textured or ribbed for grip. It can be painted or come in various colors.
* Rubber: Offers good grip and protection. Usually black.
* Aluminum: Less common, but possible, offering a more durable and potentially higher-end look.
* Wood (rare): While not original equipment, some owners might have aftermarket wood cladding.
Without knowing the specifics of your Astro Van's running boards, it's difficult to say precisely what material the cladding is made from. If you are looking for replacement cladding, you'll need to determine the original material or find a suitable replacement part from a vendor specializing in Astro Van parts. Pictures would be helpful in identifying the cladding.
