Quattro And DemiQuattro

Description

Quattro and DemiQuattro represent a pressure locked range of gratings which are characterised by a square aperture.

The process of pressure-locking produces a very high quality material with perfectly formed intersections between the vertical and horizontal flat bars, resulting in the most 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.

The range includes:

  • Quattro is manufactured from equal sections of flat bar which provides an identical eggcrate appearance from both sides.
  • DemiQuattro is manufactured from flat bars of unequal depth, the standard section of horizontal transverse bearing bar is 10 x 2 mm.

All panels are made 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.
