EditProduct Benefits

• Duplex Corrosion Protection
• Built-in Plaster Key
• Built-in DPC
• Integral Insulation

• Standard lengths are available in increments 150mm increments up to 3000mmm, 300mm at lengths 3000mm to 4800mm (including 4575mm, but excluding 4500mm)
• The SWL (safe working load) is based on the total UDL (uniform distributed load) over maximum span using 150mm end bearings
• To achieve the CH & CX loading figures indicated, lintels must be built-in as illustrated, ensuring that the blockwork infill is well-jointed during construction and compatible with the strength of thr masonry above.
• When using the Catnic CH and CX Open Back ranges with concrete floors, always ensure that the blockwork is built tight against the inner vertical face, and that a mortar joint is added to the top of the blockwork so that the floor units have an even spread over the inner flange of the lintel.
