The Xpanda Durabar range is custom built and welded to suit all applications around window apertures, requiring protection against unauthorised forced entry. All steel construction using 25mm square tube for the frame and braces, and 12mm to 20mm steel round bar, depending on individual requirements, are then welded into the frames. Bracings for the bars to pass through are spaced at no more than 600mm intervals. This provides added strength over any distance. This is done so as to prevent the bars being forced apart enough for unauthorised entry. All securing screws and pins are not easily accessible and neat caps cover the fixing points. Durabars are traditionally installed with the bars running horizontally but vertical bars can be done depending on requirements. Galvanising for exterior bars is recommended and powder coating options are also available.
