Steelfinne ModSec is a modular high-security wall and cell panel system designed for correctional facilities, police stations, mental health units and other secure infrastructure. Each panel can be integrated with custodial-grade doors and windows, allowing architects and builders to create fully secure spaces within new or existing constructions. Custom panel configurations are available to meet site-specific compliance, fire-rating, and strength requirements.

Example of a ModSec Modular cell set up

Prior to installation, a suitable space is allocated for the installation of floor and wall channels. The channels are securely fixed to the base structure.

The vertical ModSec panels, doors and any windows are stood in these channels, fixed off and welded together appropriately.

A ModSec ceiling is installed and fixed to the vertical wall panels creating a secure enclosed space.

Security features are built in to the design, such as ceiling panel clamping angles to prevent the lifting of the ceiling from inside the secure space.

Doors, windows and services according to your project specifications can be included in the setout of the ModSec. Steelfinne is able to manufacture any additional security items such as light or ventilation covers.
