BC45 Security head box

BC45 head box

The BC45 security head box material is a two-part aluminium roll formed section designed to completely enclose the working parts of the shutter. The shutter curtain (slat) is concealed in the head box when in the UP position and for this reason we have four sizes of head box. The box has two roll formed sections (Top Plate and Bottom Plate), that are fitted together with a pair of cast aluminium End Plates.

Primer: Specially formulated flexible primer with a nominal film thickness of 5 microns
Top Coat: Polyester with a nominal thickness of 20 micr

Mechanical Properties

The BC45 boxing material has excellent corrosion resistance due to the high-grade aluminium alloy used and the exceptional coating qualities. The shape of the box is designed to be aesthetically pleasing while maintaining a highly functional purpose.
Due to the strength of the shape and the lightness of the aluminium, the box will not bend over its own weight. Unlike steel boxing, the cut edges are protected by the corrosion resistant properties of the aluminium. The cast aluminium end plates are fitted using aluminium rivets, therefore offering the best resistance to galvanic corrosion or electrolysis, caused by using dissimilar metals.
