Combi decks are gratings with a chequer plate welded on top. They ideally combine the advantages of both products. Chequer plates combine a closed surface with a slip-resistant effect. Gratings, on the other hand, have a high bearing capacity with a low dead weight.
Lichtgitter combi decks are used in the industrial sector, including for the chemical/petrochemical industry, power plant and cement industry as well as for bulk materials and offshore applications as platforms.
Bridging of large spans with relatively low dead weight, resulting in low installation costs
Savings on secondary supports and reduced dimensions of the primary steel structure
Easy to install (only 4 fixing materials per combi deck are sufficient)
Preparation of verifiable static verifications for pedestrian traffic and coverings suitable for vehicle traffic
Individually tailored solutions for every static requirement
Tolerances according to RAL GZ 638 (= a high degree of accuracy of fit)
Height of combi decks individually, no height difference to any existing adjacent floorings
No interface-problems; complete range of all industrial floor coverings; "Lichtgitter - Everything from one source"
Weep plates according to DIN 59220 in galvanized steel currently have the serration class R11.

Weight comparison of the chequer plate and combi deck products in relation to the respective free span.
Basis of calculation:
Combi decks: Pedestrian traffic according to DIN EN ISO 14122 = 1.5 kN on 200 × 200 mm; deflection limit 4 mm
Chequer plates: laid-on system, without stiffening ribs 5kN/m²; deflection limit l/200
Closed surface – with chequer plates?
We have a better solution! Lichtgitter combi decks. The video shows how the Lichtgitter combi deck combines the advantages of a grating and a chequer plate in one solution. Stable, safe, smart – for optimum function and top quality.
