Which one is more rust-proof, a stainless steel lifting table or a plastic-sprayed lifting table?

A stainless steel lifting table is generally more rust-proof than a plastic-sprayed (powder-coated) lifting table, especially in environments where moisture, chemicals, or outdoor exposure are factors.
Stainless steel offers excellent rust resistance because its corrosion protection is inherent to the material itself. Even if it's scratched or dented, it continues to resist rust, particularly if it's made from high-grade stainless steel like 304 or 316. This makes it ideal for wet, humid, or corrosive environments such as food processing plants, pharmaceutical areas, or outdoor use.
In contrast, a plastic-sprayed lifting table relies on its outer coating (typically powder coating) to prevent rust. When the coating is intact, it provides decent protection. However, if the coating is chipped, scratched, or worn through, the exposed metal underneath can begin to rust. This makes it more vulnerable in harsh conditions and requires regular inspection and maintenance to ensure the coating remains effective.
In terms of maintenance, stainless steel requires less attention over time, while plastic-coated steel may need occasional recoating or touch-ups to maintain its anti-corrosion properties.
Although stainless steel is more expensive, it's the better option if rust resistance and long-term durability are your top concerns. If cost is a limiting factor and the table will be used in a dry indoor environment, plastic-sprayed steel can be an acceptable choice.
