Considering the importance of material durability in outdoor applications, what benefits can be expected from using a bike rack with a rust-resistant design, particularly in high-humidity or coastal environments where corrosion is more prevalent, and how do these benefits extend to the overall lifespan and maintenance requirements of the rack, as well as the safety and security of the bicycles being transported. Specifically, how do rust-resistant materials such as stainless steel, aluminum, or epoxy-coated steel compare to traditional steel in terms of corrosion resistance, weight capacity, and overall durability, and what are the trade-offs between these materials in terms of cost and performance. Furthermore, what role do Rust-Resistant coatings or treatments play in enhancing the corrosion resistance of bike racks, and are there any industry standards or certifications that ensure a bike racks rust-resistant design meets specific performance and durability requirements.
