What type of steel should I specify for an electronics enclosure?

September 10, 2008

Hello,

I am planning to have an enclosure fabricated for some electronics, and am wondering what type of steel to specify. I was advised that I should use CRCA steel and the power coat, but I read on this forum that CRCA is prone to rusting.

My question is, what type of steel should I request from the fabricator?

Also, another question:

- What type and thickness of power coating should be specified? (I understand that the usual thickness is 40 microns)

Some additional background:

- The enclosure is for indoor use
- Environment is very dusty and humid
- Temperatures can be even 50 (ambient)

Thanks!
