Without more context, it's impossible to definitively say if the supports are odd. "Odd" is subjective and depends entirely on the application and what the supports are supporting.However, the statement "I'd think they should be stainless or PVC coated" strongly suggests that the current supports are not stainless or PVC coated, and that this is the source of concern. This concern implies that the current supports are made of a material susceptible to: Corrosion

Stainless steel and PVC coatings are often used to prevent rust and corrosion, especially in environments with moisture, chemicals, or harsh weather. If the current material is prone to rusting (like uncoated steel), using stainless or PVC coated alternatives would be a significant improvement.

Chemical Degradation

PVC coatings are good for dealing with chemical degradation.

Therefore, to determine if it's "odd" to NOT have stainless or PVC coated supports, we need more information


What are the supports holding up? (e.g., pipes, machinery, electrical conduit, structural elements)2. Where are the supports located? (e.g., indoor, outdoor, near the ocean, in a chemical plant, food processing facility)3. What material are the current supports made of? (e.g., uncoated steel, wood, aluminum)4. What are the applicable industry standards or regulations?Here's a breakdown of why stainless steel or PVC coating might be preferred



Stainless Steel



Pros

Excellent corrosion resistance, durable, strong, easy to clean, long-lasting.

Cons

More expensive than other materials, can be susceptible to pitting in some environments.

PVC Coating



Pros

Good corrosion resistance (especially to chemicals), less expensive than stainless steel, can provide electrical insulation.

Cons

Not as strong as steel, can be damaged by abrasion or high temperatures, may not be suitable for all environments.

In summary, the "oddness" hinges on whether the environment and the load being supported warrant the added protection offered by stainless steel or PVC coating. Without that information, we can only assume that the user has identified a potential risk of corrosion or degradation of the existing support material.
