Modern Steel Security Door with Smart Lock — Dark Gray & Walnut

A steel security door with smart lock is one of the smartest upgrades you can make to a modern entrance. The CEALUM model pairs a brushed dark-gray steel panel with a warm walnut accent strip and a slim black frame, giving you the strength of steel with the warmth of wood — no compromise between security and style.

Whether you are renovating a villa, fitting out an apartment, or specifying doors for a commercial building, this door delivers keyless convenience, multi-point protection, and a clean architectural look that fits contemporary façades.

Security & Lock System

Security starts at the core. The door uses a reinforced steel core with a multi-point locking system that engages the frame at several points — far stronger than a single deadbolt. The integrated keypad smart lock supports keyless entry, so you never worry about lost keys again.

• Built-in keypad smart lock with keyless entry

• Multi-point locking for reinforced anti-intrusion protection

• Reinforced steel core resists impact and forced entry

• Optional mechanical key override for backup access

Materials & Finish

The panel is finished in a durable brushed dark-gray coating that resists scratches and weather, framed by a slim black profile for a modern, minimalist edge. A natural walnut accent strip adds warmth and visual contrast, so the door reads as design-forward rather than industrial.

• Brushed dark-gray steel panel

• Natural walnut accent strip

• Slim black frame profile

• Low-maintenance, weather-resistant surface
