Fundamental Design Principles for Waterproof Counters

Enclosure andSealing Strategies

Te first st line of defense is the physical housing. Designers choose corrosion- resistant materials like marine-grade barinless steel (316L), anodized alumminum, or equired polimers such as PEEK or PTFE. Enclosures are e sealed using a combination of techniques:
