The manufacturing of EP gratings (type EP - Einpress-Gitter / press-in gratings):

The spacing bars are pressed-in by high pressure into the prepared slots of the supporting bars. For to reach high sturdity : in the centre the slots are tapered.

materials : steel, stainless steel, aluminium
Strip Steel  K60
Strip Steel  K60
The supporting bars are bearing the load - the spacing bars are
distributing the load giving sturdity.

Our gratings are available with frame or without frame.

The mesh size is the width between the bars. In contrast to this, the division of the mesh ist the distance between the centres of the bars.

Full gratings are made of supporting bars and spacing bars in the same height.

The distance between the saddles is the distance between the centres of the saddles.

The span ist the clearance between two supporting beams.
The distance between the saddles
The saddle of the grating must be at the minimum =25-30mm. Deviations are only allowed for to avoid displacement of the gratings. Placement of ADMAR gratings
