Application

Suitable for vertical applications such as balconies, balustrades, ceiling panels, security screens and brise soleil.

Description

A pressure-locked range of gratings, which is characterized by a rectangular aperture. The process of pressure-locking produces a material with perfectly formed intersections between the vertical and horizontal flat bars, resulting in an aesthetic grating for vertical applications. The flexibility of this method of manufacture means that production can be readily adapted to provide gratings to individual specifications of weight, aperture and performance.


Features and benefits:

  • Alto is manufactured from equal sections of flat bar, which provides an identical appearance from both sides.
  • DemiAlto is manufactured from flat bars of unequal depth, with a 10 x 2 mm standard section of horizontal transverse bearing bar.
  • All panels are manufactured to custom sizes and supplied framed and fully finished.
  • Panels and posts can be supplied galvanized only, or galvanized and powder coated to any RAL colour.
