Load-rated metal grating, wire mesh, and perforated panels stocked across 19 service centers—mill-certified, ASTM-compliant, and ready for plant floors, platforms, and architectural screens.
From a regional grating distributor to a national network of cut-to-size service centers, McNichols has tightened the path from load table to dock door.
McNichols opens to supply steel bar grating and stair treads for plant platforms where load bearing capacity and open-area drainage matter more than catalog photography.
Welded wire mesh, woven mesh, and perforated metal join the core grating offering so plant engineers can source screens, guards, and architectural panels from one mill-certified channel.
Fiberglass grating and plank systems enter stock for wastewater clarifiers and chemical corridors where steel corrosion shortens service life expectancy below project budgets.
Local inventory plus fabrication cells ship ASTM A1011 / A36 packages with mill test reports, ANSI/NAAMM MBG 531 references, and IBC load compliance notes attached to the packing list.
Hole products earn their keep on platforms that must drain, vent, and carry live loads without guessing at slip resistance or open-area percentages.
★★★★★
“Bearing-bar tables matched our IBC live-load case on the first submittal. Cut-to-size panels arrived with mill certs attached—no rework on the mezzanine pour schedule.”
★★★★★
“We swapped carbon steel for FRP grating over clarifier bays after water absorption and chemical splash ruined prior decks. McNichols stocked the plank profile we needed without a mill-run wait.”
★★★★★
“Perforated facade panels shipped with dimensional stability notes and open-area percentages our architect could defend in review. Installation stayed on the curtain-wall critical path.”
