McNichols cuts to order — reducing jobsite waste and overstock. Our mill-certified materials are fully traceable, and all fabrication scrap is 100% recycled.
"We spec McNichols bar grating on every industrial walkway project. The mill test reports arrive with the order, and their technical team actually understands ANSI/NAAMM MBG 531 — which is rarer than it should be."
"Ordered 47 custom-cut panels on a Thursday, had them on site by Monday. That kind of turnaround keeps a water treatment plant shutdown on schedule. No other supplier comes close."
"The FRP chemical resistance tables on their support page saved us two weeks of specification research. We specified ISO VE resin for a sulfuric acid environment based on their data — worked exactly as documented."
