Floor Gratings from the expanded metal

Floor gratings from the expanded metal are welded products from expanded metal, circumference frame and length reinforcement. Floor gratings are tailor-made in dimensions and shapes according to customer requirements. The most used marerial is mild steel and stainless steel.

Application

Floor gratings from expanded metal are widely used – mainly in following areas:

• machine operating platforms in industrial and power production
• crane and crane runway platforms
• footpaths on bridges and walkways
• covers of channels and skylights with walking use
• staircases

Advantages

Main advantages of floor gratings from expanded metal are easy maintaince, big bearing capacity with small grating weight, anti-slip effect with safe walk in woman shoes.

Surface treatment

Floor gratings from expanded metal are supplied:

• Raw – without any surface treatment
• Hot dip galvanized due to DIN 50 976
• Painted

Indication of floor gratings from expanded metal

Example: TR 62,5 x 15 / 3 x 5 / 20 x 3 / 600 x 1000

TR - mesh type
62,5 x 15 - mesh dimensions
3 - strand thickness S
5 - strand width S
20 - reinforcement height h
3 - reinforcement thickness b
600 - bearing length
1000 - non-bearing width

Expanded metal type 62,5 x 15 / 3 x 5 is used for floor gratings and stair steps.

Expanded metal type 47 x 13 / 3 x 4 can be also used

Load of expanded metal gratings

Legend:
Fv - continuous load in kN/m² including of load factor 1.4
fv - maximal deflexion of step reinforcement in mm with load Fv. Local deflexion of expanded metal can be approx. 2 mm bigger.
