1. Manufacture Aluminium gratings are manufactured by a high-power pressing process in which all joints are made without welding. The finished panels can be cut to size at any point without impairing the strength and rigidity. 2. Product Code ExampleI-Bar aluminium gratings can be manufactured with a variety of bearing bars. The main specifications are listed below.
