Chosen parameters from technical delivery terms


  • Mild steel quality DD11
  • Stainless steel quality AISI 304

Loading capacity of floor gratings

  • Loading capacity is determined by tables.
  • Mentioned tables are valid for spacing module 33 mm and 25 mm, for continuous load (in kN/m2) and load caused alone force (in kN), which impacts in the most unfavourable place i.e. on the area 200 x 200 mm in the middle of grating.
  • Corresponding deflexitions are stated by values fv possible fp.

Dimension and geometric tolerances

Parameter Specification Maximal allowed divergence (mm)
shape Dimensions (length and width) + 0, -3
Shape rectangularity Difference of diagonals lengths 6/1000 of longer format dimension
Flatness of surface Up to format 500 mm 2
Straightess of border Over format 500 mm 1/250 of longer format dimension

Maximum dimensions of grating are 2000 x 1500 mm (bearing length x width)

  • All floor gratings and stair steps stated in catalogue are only basic manufactured types.
  • Our advantage is flexible reaction for Your special requirements in our production no matter what it concerns – cross-section of bearing rod, mesh size, material quality, surface treatment etc.
  • In case of supply of irregular shapes or gratings with cut outs, the grating surface is counted as surface of circumscribed rectangle of the grating.
  • We offer completed four-part kit containing upper shaped clip, bottom clamp with nose and connecting screw M8x60 with nut M8 for standard mesh sizes. Whole kit is electrogalvanized.
  • Recommended number of mentioned connecting parts is 4 pcs / grating regarding the grating dimensions.
  • We are ready to consult with You any other application of gratings as well as with untypical mesh size or grating shape or dimensions.
  • We offer You, as our Customers, complete service - technical consultation and advise about suitable grating type due to Your stated use including kind and value of load capacity.
