Does serration reduce load capacity?

For the same bar dimensions and spacing, capacity is taken as equivalent to plain top in most catalogs; confirm with the supplier table footnotes.

Can serrated grating be galvanized?

Yes; serrated profiles are routinely hot-dip galvanized after fabrication.

When is serrated unnecessary?

Dry indoor storage mezzanines with low slip hazard may use plain tops—document the HSE basis.

How do I match stair treads?

Specify the same mesh family and nosing detail as platforms for visual and gait continuity.

Is press-locked serrated available?

Yes in many meshes; ask during RFQ if architectural flatness is also required.

What standards reference slip?

Owner HSE and local codes govern; grating provides the surface texture input to those rules.

Specifications

Serrated bearing bars — saw-tooth notches on the top edge of each load bar. Same construction as welded or press-locked grating
Bearing bars: 25 × 5 through 50 × 5 mm (serrations reduce bar depth slightly from plain equivalent)
Spacing: 30 mm standard for maximum slip resistance. 40 mm for light-duty
Material: carbon steel ASTM A36 / S275JR hot-dip galvanized. Stainless 316L for marine and chemical
Applications: offshore platforms, refinery process areas, cooling towers, outdoor walkways, oil-exposed zones
Slip resistance meets AS 4586 R12 / EN 13201-4 requirements
