Ball-proof steel grating (20 mm / 35 mm)
20mm and 35mm ball proof grating for fall-through protection on walkways and platforms. Compliant with safety standards for opening size.
Openings limited so a 20 mm or 35 mm test ball cannot pass — fall-through protection for walkways and platforms. State which ball size and which standard your project follows in the RFQ.

Ball-proof grating applications
Data centers
Walkways over white-space adjacencies where owner dropped-object programs reference sphere passage limits.
Power generation
Elevated routes above turbine or boiler auxiliaries when insurance or owner standards mandate proof against reference ball sizes.
Oil & gas
Offshore and module walkways tied to DROPS-style rules; always cite the governing sphere diameter in the RFQ.

Documentation engineers expect
State 20 mm or 35 mm proof, mesh designation, span, and standard reference. Use ball-proof load tables and compare with close-mesh alternatives.
Frequently asked questions
What does ball-proof mean?
Openings are configured so a defined test sphere (commonly 20 mm or 35 mm) cannot pass—wording varies by owner; cite the rule you follow.
Is ball-proof the same as close-mesh?
Close-mesh is a geometric description; ball-proof ties to a specific test sphere and jurisdiction.
Can ball-proof mesh be galvanized?
Yes with venting suitable for tight patterns.
How are loads determined?
Use the supplier ball-proof table for the mesh and span; do not assume standard-duty values.
Does serrated top affect proof geometry?
The opening check must still be satisfied; confirm with drawings.
Offshore vs onshore specs?
Regulatory and owner standards differ—attach the applicable document to the RFQ.
