E-Invest offers its customers the opportunity to purchase serrated grating, i.e. steel grating that is given increased strength during the manufacturing process. As a result, serrated grating is characterized by an increased coefficient of friction. The flat bars of such steel sheets and gratings have special serrations cut into them to increase the anti-slip properties. You can use serrated grating as grating for steel stair treads and platform grating.
These gratings are used to cover platforms wherever increased safety is required due to the presence of snow, ice, grease and high levels of moisture.

We offer our customers serrated gratings in both welded and pressed versions. Pressed gratings and welded gratings differ in production technology and technical data.

Types of serrated gratings

Four types of steel gratings offered by E-Invest can be distinguished:

  • welded gratings with cutouts on supporting flat bars,
  • pressed gratings with cutouts on supporting flat bars,
  • pressed gratings with cutouts on connecting flat bars,
  • pressed gratings with cutouts on bearing and connecting flat bars.

Serrated gratings are characterized by an increased coefficient of friction. The flat bars have special serrations cut into them to increase the anti-slip properties.

These gratings are used to cover platforms in areas where increased safety is required due to the presence of snow, ice, grease and moisture.

Gratings of Serrated type are made by both welding and pressing technology. Technical data (loads, weights, mesh sizes, dimensions of supporting flat bars) are the same as for gratings with smooth flat bars.

Serrated grating designations:

  • Type X4 – welded gratings with cutouts on supporting flat bars
  • Type X5 – pressed gratings with cutouts on supporting flat bars
  • Type X6 – pressed gratings with cut-outs on connecting flats
  • Type X7 – pressed gratings with cut-outs on bearing and connecting flat bars

Serrated gratings are made in various shapes and sizes, according to the wishes of the customer.
