Manufactured using highly performance, the pressed gratings present a solid reticulated, flexible and robust structure. Suitable for many applications, from industrial flooring to civil engineering, it is particularly recommended for its high loadbearing capacity.


Our pressed gratings are referred to as "interlocking" in order to best define the junctions of the bars (both loading and connecting). This system joins the connecting bars to the load-bearing bars using high pressure, creating a perfect joint that is essential for the compact, homogenous structure. The construction method, and the physical principles on which the jointing technique is based, result in a pressed grating that is extremely suitable for uses that require a high load-bearing capacity. he manufacturing process used is, today, the most advanced in the sector, thanks to the application of our extensive experience, and our highly reliable plant and equipment.


- solid structure: flexible and silent, absorbing any leveling errors in the installation site;
- no welds: greater joint safety when exposed to thermal variations.

UNI regulations

Our gratings comply with the regulations defined by ASSOGRIGLIATI, the Italian National Association of Steel and Metal Alloy Welded or Pressed Grating Manufacturers. The applicable regulations as of August 2002 include the UNI regulations for electro-welded / pressed gratings:

- UNI 11002-1: Panels and steps formed of welded or pressed gratings, terminology, tolerances, requirements and testing methods for panels for applications in pedestrian or vehicle-accessible applications.

- UNI 11002-2: Panels and steps formed of welded or pressed gratings, terminology, tolerances, requirements and testing methods for steps.

UNI 11002-3: Panels and steps formed of welded or pressed gratings. Sampling and criteria for acceptance of panels for use in pedestrianized areas, vehicle-accessible areas, and steps. .


Technical selection criteria for grating panels:
 - Use of capacity tables, "collaborating bars" method;

- Use and intallation of grating panels (survey of site, installation of the panels, setting of the gratings, pedestrian gratings, empty/full relationship of grating panels, break beams, trolleys and forks);

- Criteria for dimensions of grating steps for public stairwells (loads acting on the steps, collaborating bars, restrictions on bolted steps etc.).


Class 1: small crowds
Class 2: automobiles
Class 3: LGVs
Class 4: HGVs / artics


The manufacturing process involves forcing the transverse plates into slots cut into the load-bearing plates by applyng very high pressure. The loading plates are arranged paranged parallel to each other in one of the comb stamps fitted to the press. The transverse plates are then aligned with the notches cut for them in the load-bearing plates by two belt shears and forced, by a high-pressure press, into the notches.
This forms a reticular structure of high solidity, robustness and resistance, with optimal load spreading.
