Steel Grating vs Expanded Metal

Both are open metal, but grating is a load-rated structural product and expanded metal is a stretched sheet for lighter duty.

The verdict

Choose grating for any load-rated walkway, platform or vehicle area. Choose expanded metal for light foot traffic, guards, fences, infill panels and architectural screens where loads are modest.

FAQ

Can you walk on expanded metal?

Light-duty foot traffic only, over short spans. For load-rated industrial walkways and platforms, bar grating is the correct choice.

Why is grating more expensive than expanded metal?

Grating uses more steel and fabrication to achieve its high, predictable load capacity, whereas expanded metal is a lighter stretched sheet.
