Stop Over-Specifying Grating: Why 'McNichols' Isn't Always the Answer (and When It Absolutely Is)

I Think Most People Get This Wrong: Specs Aren't About 'Best'

Here's the thing. When I talk to engineers or facility managers new to specifying industrial grating, the conversation almost always circles back to the same impulse: "I want the most robust, highest-rated product McNichols carries."

They'll point to a catalog and say, "Give me the heavy-duty, 300-series stainless steel mesh, because I don't want to deal with rust ever again."

I get it. I had that instinct too. But after eight years of ordering metal and fiberglass grating—and making about $15,000 worth of preventable mistakes—I've learned the conventional wisdom is backwards. You don't start with the strongest product. You start with the right product for your exact environment. And sometimes, that means picking something simpler, like a painted steel or even fiberglass, even if you're a 'buy once, cry once' type.

Let me walk you through my biggest failures and the framework I now use to avoid repeating them.

Why I Stopped Defaulting to 'The Best' (A $3,200 Lesson)

My First Mistake: The Stainless Steel Trap

In my first year, 2017, I was specifying for a new indoor catwalk system. The environment? A dry, climate-controlled warehouse. Everything I'd read about industrial mesh said '304 stainless for longevity'. So that's what I ordered: McNichols 304 stainless steel plank grating.

I assumed stainless was always the superior choice. Didn't verify the environment's actual corrosiveness. Turned out, for a dry interior, we were paying roughly 2.5x the cost of a hot-dipped galvanized alternative for zero functional gain. The mistake affected a whole 1,200 sq ft order. We wasted $3,200 on material we didn't need, plus we waited an extra week for fabrication. It looked beautiful, but it was a stupid decision.

Honestly, the worst part was the embarrassment when the senior project manager asked to see the cost breakdown. Basically, he just looked at me and said, "We could have built two walkways for that price." (Note to self: always consider the real-world environment before defaulting to the catalog's top tier.)

The Second Mistake: Ignoring the 'Light Duty' Label

Fast forward to 2021. I was ordering for a secondary mezzanine with very light foot traffic—mostly just a path for maintenance to check a few pipes. I saw a great deal on a heavy-duty McNichols welded wire mesh. I thought, "More strength can't hurt."

When I compared that heavy-duty order side-by-side with the standard duty mesh I eventually used for a different area, I finally understood why the details matter so much. The heavy-duty mesh was cheaper per square foot in bulk, but it was heavier. It required extra structural support for the mezzanine itself. The total installed cost was 18% higher than the 'light duty' option.

I assumed 'same price per pound' meant a better deal. Didn't account for installation costs. Learned never to assume the material cost is the total cost. The lighter mesh was perfectly sufficient, and it saved us a headache.

Why You Should Trust a Supplier Who Says 'No'

This brings me to the core of my argument: the best suppliers aren't the ones who say 'yes' to everything. The best ones help you avoid over-spending.

Here's what I tell my team now: a supplier like McNichols has a huge catalog. That's their strength. But that breadth can be a trap for the inexperienced. When you call them and say "I need grating for a catwalk," a sales rep who just takes the order might quote you the premium option. A partner who knows their stuff will ask: "Indoor or outdoor? What's the expected foot traffic? Any chemical exposure?" They'll guide you to the right spec.

If you're dealing with a situation where the rep says 'this is the only option,' that's a red flag. A good one will explicitly tell you where their product doesn't fit. For example, I've had excellent reps say, "For your application—a dry, interior mezzanine—fiberglass grating is overkill. You'll get better value from our standard galvanized steel plank."

This is the 'honest limitation' principle. A recommendation without caveats is just a sales pitch. A recommendation with clear boundaries is trustworthy advice.

The 'Check Valve' Test (A Metaphor)

I think of product selection like choosing a check valve for a plumbing system. You don't buy the most expensive brass valve with a stainless steel spring if the system only handles 60 PSI of clean water. A simple, reliable PVC valve is the best choice. Over-specifying introduces unnecessary cost and possibly even incompatibility (weight, connection sizes). Choosing the fitting component for the specific load is the whole game.

But Shouldn't I Always Prepare for the Worst Case?

I know what some of you are thinking. "But what if conditions change in the future? What if the catwalk gets used for heavier equipment later?"

Those are fair concerns. I used to think the same way. But my experience suggests that preparing for a vague, undefined 'worst case' is a recipe for budget overruns and project delays. It's like buying a fire truck for your company car 'just in case' you need to transport a fire truck. It's not a realistic risk.

Instead, we should ask: What is the most extreme realistic scenario I can actually define? Not a hypothetical disaster, but a plausible future use case. If there's a defined plan to upgrade the mezzanine's load capacity, then you plan for that. If it's just a vague worry, stick with the right specification for the current requirements.

Bottom Line: Choose the Solution, Not Just the Brand

Look, McNichols is a fantastic resource. I've used their wire mesh, grating, and stair treads on dozens of successful projects. Their catalog is a goldmine of options. But that's the point—it's an option set, not a prescription. Your job isn't to find the most prestigious option in the catalog. Your job is to match the product to the problem.

So before you specify your next order of mcnichols wire mesh or grating, ask yourself: Am I picking this because it's 'the best,' or because it's the best fit for this specific situation? Be honest about the limitation of a 'universal best' solution. That honesty will save you time, money, and a lot of embarrassment.
