Open Mesh Grating
Open mesh grating is made of steel plate welded to the top surface during manufacture.

Open mesh grating processing:
By forge-welding technology connecting metal sheets using heat and force. Method whereby heat is generated at the metal intersection points by an electric current and, as the forging temperature is reached, pressure is applied and the materials are forge-welded together.

Open Mesh Grating is anti-slip, lightweight, strong and durable, manufactured in standard size and custom specifications for easy and quick installation, saving installation time, transport costs and labour.

Louvre Grating (Perforated Panels)

Louvre gratings are sturdy mesh grids of choice steel ribbons made into bearing bars and crossbars. Popularly used in sun shading, ventilation, facade cladding and suspended ceilings.

Louvre gratings are manufactured being pressed at an angle of 45° or 30°. The grate frame is usually made of flat steel. The louvres (crossbars) can be fitted at an angle of 30º or 45º. The panels have a standard, 5 mm thick, edge bar to ensure stability and rigidity. Transparency can be varied by modifying the height of the louvres (crossbars) and the mesh width. Louvre grating materials: Aluminium, steel.
