The Complete Guide to Choosing Security Doors for Your Home

Home security starts at the entrance. A high-quality security door is the single most effective deterrent against forced entry, yet many homeowners choose based on aesthetics alone without understanding the technical specifications.

Understanding RC Ratings

Resistance Class (RC) ratings are European standards for burglar resistance. RC2 doors can withstand a determined attack using screwdrivers, crowbars, and wedges for at least 3 minutes. RC3 doors resist attacks using power tools for the same duration.

For most residential applications in Tanzania, an RC2-certified door provides excellent protection. High-value properties and commercial buildings should consider RC3 or above.

What to Look For

Beyond the RC rating, look for doors with at least 5 locking bolts on the active side, anti-drill plates behind the cylinder, and a heavy-gauge steel frame. The frame is often the weakest point — a quality door in a poor frame provides minimal protection.
