What to look for
Climate sets the grade
Inland and dry: 304 or galvanized. Coastal: 316. That single choice prevents most outdoor hinge complaints.
Security pins
NRP hinges on out-swing doors so they can't be lifted off.
Finish for UV and stain
A quality satin or coated finish resists fading and surface staining outdoors.
Self-closing gates
Add self-closing hardware to gates where safety or code calls for it.
Where to start shopping

Common mistakes to avoid
- Treating "outdoor-rated" as one standard — grade and coating vary widely.
- Using 304 within salt range.
- Carbon-steel fasteners with stainless hinges.
- Ignoring NRP pins on out-swing exterior doors.
Frequently asked questions
Powder-coated steel vs stainless outdoors?
Powder coat looks good until it chips, then the steel underneath rusts. Stainless resists corrosion through the material, not a coating — better long-term outdoors.
Do outdoor hinges need maintenance?
Minimal for stainless — an occasional rinse and dry lube. Coated steel needs touch-ups wherever the finish wears.
Galvanized or stainless outdoors?
Galvanized is a fine budget choice inland. Near salt, 316 stainless is the durable, better-looking answer.
