Steel Gratings - Ventilation Grilles and Flooring

Description

Grating panels are made in a wide range of apertures. The different apertures provide alternative levels of free area to meet ventilation and project requirements.

Pressure Locked Gratings (Type-PL):

Pressed gratings which are manufactured exclusively from flat bars. They are available in the following apertures: 22 x 22, 22 x 66, 33 x 33, 33 x 66, 44 x 22, 66 x 22 and 66 x 33 mm. The bearing bar can vary from 25 x 2 to 150 x 5 mm and the transverse bar from 10 x 2 to 20 x 4mm to meet different loading/ span requirements.

Pressure Locked Gratings (Type-PLX):

Cross pressed gratings designed for heavy duty vehicle loadings which are manufactured exclusively from flat bars. They are available in the following apertures: 22 x 66, 33 x 33, 33 x 66, 25 x 66 and 66 x 33 mm. The bearing bar can vary from 30 x 4 to150 x 6 mm and the transverse bar from 15 x 4 to 30 x 6 mm for different loading/ span requirements.

Pressure Locked Gratings (Type-PLXE):

Cross pressed gratings which are manufactured exclusively from equal depth flat bars. The equal depth of flat bar means that the grating has the same egg-crate appearance from both above and below for a pleasing aesthetic. The flat bars can also provide a greater level of shading for brise soleil applications. PLXE gratings are available in the following apertures: 33 x 33, 44 x 44, 25 x 66 and 66 x 33 mm. The bearing bar can vary from 30 x 4 mm to 150 x 6 mm and the transverse bar from 15 x 4 mm to 30 x 6 mm for different loading/ span requirements.

Electrofused Gratings (Type-EF):

Manufactured from flat bearing bars and round transverse bars and available in the following apertures: 22 x 76, 22 x 38, 25 x 76 and 25 x 25 mm. The bearing bar can vary from 25 x 3 to 80 x 4 mm and the transverse bar from 4-6 mm in diameter for different loading/ span requirements.

Any grating with an aperture 22 mm wide or less can be classified as a safety grating in accordance with BS 45920: 2006. These gratings will prevent the passage of a 20 mm sphere.

Framed panels are manufactured to custom-sizes for a wide variety of applications such as walkways, balcony decking, ventilation grilles, service platforms, escape stairs and brise soleil.

Panels and support steelwork are supplied hot-dip galvanized with an option for an additional polyester powder coating to any RAL colour.
