Aluminium Profiles

Box Sections

Vertical application
Floor to floor
Heavy materials

Box Sections are engineered to support large cavities and where there is a need to span between floors. The profiles are also used if building substrate is variable or where a subframe needs to carry heavy weight facade materials - including natural stones with a typical thickness greater than 40mm and glass. All sections are 50mm wide face, the depth varies from 25mm to 180mm and they are designed for U shaped brackets.

    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 RJ Facades technical department.
