What to look for
Load and cycle first
Match per-hinge or per-pair load ratings to the actual door or panel weight with margin, and choose ball-bearing or geared for high cycles.
Weld-on vs bolt-on
Weld-on barrel and bullet hinges suit steel fabrication; bolt-on for serviceable installs.
Grade for the atmosphere
Wash-down, food, and chemical plants want 316; general plant air is fine with 304.
Continuous for abuse
Full-height continuous hinges spread stress on heavy, frequently abused doors and panels.
