There are some benefits to using a metal carport instead of a temporary plastic car shelter. A metal carport is sturdier and can hold up better to winds and harsh weather. It can also last longer as plastic tends to get damaged rather easily.
There are a number of reasons: If the wire is electrical then it is covered in plastic as plastic provides insulation, this means that if adjoining wires come into contact the electrical current would not cause a short circuit. Normally electrical wire is cooper as it is a good conductor of electricity and does not oxidize/ rust easily. Secondly wire hangers are covered in plastic to prevent the metal (normally mild steel) from rusting. If they were to rust, it would cause orange/ red stains on your clothes.
