Terra-34

Description

Terra-34 is manufactured from vertical flat bars at 34 mm centres and plain round bars. Defined by its narrow aperture which complies with the National House Building Council’s anti-climb guidelines.

The narrow aperture between the flat bars make it a good choice for balconies, balustrades and any grating project where the panelled area extends to ground level.

Framed panels are manufactured to custom-sizes and provide security, natural daylight and ventilation for a wide variety of applications such as wall cladding, car park screens, balconies and balustrades, plant housing and ventilation grilles.

The standard flat bar is 25 x 3 mm deep but a wider section of 30 x 2 mm or 30 x 3 mm can be supplied for a more distinctive appearance and increased level of screening (minimum quantity 400 m²).

Panels and ancillary steelwork can be supplied galvanized only or galvanized and powder coated to any RAL colour.
