The environment in which the custom roller chain operates is another significant factor to consider. Chains that are used in corrosive or high-temperature environments will require special treatments or materials to ensure their longevity. For example, a custom roller chain used in a food processing plant may need to be made from stainless steel to resist corrosion, while a chain used in a furnace application might require high-temperature coatings or materials that can withstand severe heat.
