Mailboxes: 304 Lock Boxes vs Galvanized Posts

 

Why 304 boxes resist crowbar attacks?
1.2mm steel requires power tools to breach. Welded hinges prevent prying. Choose tamper-proof locks with 304 shackles.

 

Hot-dip galvanized (G90) posts last 15+ years. Set in concrete with drainage gravel. Cap tops to prevent water intrusion.

 

Spray graphite lubricant monthly. Install weather hoods facing away from prevailing winds.

 

Theft-deterrent installation?
Bolt to concrete footing with shear-head bolts. Weld rebar cages inside hollow posts.

 

Repaint exteriors every 3 years. Check door seals annually. Replace when dent depth exceeds 3cm.
