Commercial High Security Doors
Innovators in the design, manufacturing and installation of security doors.
Shellen Security's High Security Doors are an ideal form of door protection for commercial use. They are specifically designed to be used in locations such as electrical intake cupboards, computer rooms and lift motor rooms.

In the design process of High Security Doors, we take into consideration the specific security level required based on the location and vulnerability. Our design team will recommend various door core constructions. These range from a thickness of 44mm to 54mm. Different strength levels of cladding can be applied to the face of the doors in either GRP or steel faced lamination. Finally, our unique 'U' channel system is used to encapsulate all the perimeters of the doors.

Based on the structural opening, we will design doors which will give maximum strength in an 'attack' situation. These may range from single to double doors together with side or over panels constructed from the same materials. These doors can also be controlled with mechanical or electronic locking systems.

The doors are secured with two important components:

• a full length 45mm wide continuous hinge leaf, made out of 2mm stainless steel, fixed with stainless steel security head machine screws. This provides maximum security and durability.

• 3mm stainless steel gap guards are routed flush to the external door face and bolted through the door with machine screws with captive receivers welded onto the internal part of the gap guard.
