Home > Companies > Lang+Fulton > Alto And DemiAlto

Alto and DemiAlto represent a pressure-locked range of gratings which are characterized by a rectangular aperture 132 mm high.

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.

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; the standard section of horizontal transverse bearing bar is 10 x 2 mm.

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.
