Horizonal rail systems are typically fixed to vertical rails in a T & L geometry. The majority of facades can be designed using 2mm vertical sections, although there structurally required 3mm sections are specified. Use Fischer FZP undercut anchors for fixing the panels to the hanger brackets.

The horizontal rail can be fixed to the vertical rail using tek screw or rivet connections. The horizontal rails are designed to span 500-600mm between the vertical support structure.

FischerBWM ATK103P, 3mm horizontal rail system is available in 20mm and 30mm deep sections, with hanger brackets available in 36mm, 60mm and 80mm widths. FischerBWM engineering will specify the hanger brackets depending on the façade panel size and weight.

Bracket and rail systems from Fischer are interchangeable based on the project requirement. 'Helping Hand' brackets from ATK100 Minor, concrete range, are the example in the image. ATK 100 are the most cost-effective bracket selection from the range. To achieve improved thermal performance to concrete substrate use ZeLa brackets.

FischerBWM offer Europe’s largest range of ‘Helping Hand’ brackets which have been designed to help achieve the U-value. Bracket systems range from the ZeLa range, designed to achieve passive house levels of performance, to standard L brackets that suit most project requirements in the UK.

    Typical bracket configuration uses the Fixed Point bracket at the highest position on the vertical rail to support the façade vertical dead loads. The Sliding Point bracket is used typically on all other positions on the vertical rail to absorb the project wind loading. Bracket configuration is specified by FischerBWM engineering department.
