McNichols Mesh & Fiberglass Grating: A Procurement Checklist I Wish I'd Had

I've handled material orders for industrial facilities for eight years—and I've personally made and documented six mistakes that added up to just shy of $9,000 in wasted budget. Now I keep that history on a checklist so the next person buying grating doesn't repeat it. This article is that checklist. It's for contractors, engineers, and facility managers ordering metal grating, fiberglass grating, or perforated mesh from suppliers like McNichols. It won't replace structural engineering, but it will keep most of the expensive typos out of your PO.

Use this checklist when you're about to order McNichols mesh, McNichols fiberglass grating, steel grating, or any custom fabricated material—especially if you're under deadline and working off memory.

Step 1: Write down the operating environment before you pick a material

It's tempting to think you can just order "the same thing as last time." That advice has cost me more than any other single mistake. In my first year in this industry (2017), I ordered galvanized steel grating for a water treatment ozone contact area. The price was fine and the load table matched. I didn't stop to ask about the chemical atmosphere. Within eight months, the coating was blistering and rust was bleeding into the walkway. $3,200 in material went to scrap, plus another $750 in removal and re-rental costs.

Now I write down five things before I open a catalog: indoor/outdoor, expected chemical exposure, moisture/washdown frequency, UV exposure, and temperature range. If any one of those pushes me toward high corrosion resistance, I start with fiberglass grating—specifically, McNichols' fiberglass line—rather than carbon steel.

Step 2: Measure the clear span, not the whole pit

On a $3,600 order, I once ordered grating sized for the full length of a trench. The real work required a 2-inch bearing lip on each side, which meant the clear span was shorter than the pit. Nothing fit. I considered "fixing it in the field," but cutting would expose bare steel and void the coating warranty.

Measure the unsupported span between bearing points. If you're not sure the manufacturer understands the layout, send a marked-up drawing. For custom rectangular panels, suppliers like McNichols can cut-to-size, but they need accurate measurements. This isn't the place for a guess.

Step 3: Match the material and style to the use case

I once told my boss, "Steel or fiberglass either works." That was the kind of overconfidence that gets people in trouble. Steel bar grating is excellent for heavy loads, dry environments, and simple budgets. Fiberglass grating is non-conductive, corrosion-resistant, and much lighter—so it's a better fit near electrical equipment, chemical storage, or coastal air.

Here's a comparison that stuck with me: you wouldn't call Glass Doctor to replace a toilet fill valve. They fix glass; that's their niche. Ordering the wrong material for a process area is the same kind of mismatch. Use that same logic when specifying McNichols fiberglass grating versus welded steel grating. Don't default to whichever product family you know; default to the one that survives the environment.

Step 4: Calculate total cost of ownership, not unit price

The cheapest quote usually hides the most expensive story. Earlier this year, I got three quotes for McNichols mesh. The lowest base price was 15% below the nearest competitor. But that same quote added freight, a cutting setup fee, and a delivery window that would have forced me to expedite. When I added it all up, the "cheap" quote came out $790 higher than the second option—and still arrived two days later.

Total cost of ownership includes: base price, freight, cutting, coatings, delivery date, rework risk, and schedule impact. The one that catches most people is schedule impact. A $50-per-panel saving is meaningless if the shipment arrives a week late and you have a crew on standby. Write down the full number before you sign anything.

Step 5: Put everything in writing—even with suppliers you trust

I knew I should send a formal PO with specifications, delivery date, and acceptance terms. But I thought, "We've used this salesperson for years; a verbal confirmation is enough." That was the one time it mattered. The promised ship date got lost in a loaded conversation, the order moved out three days late, and my client paid for an idle crew on a Saturday.

That cost wasn't on the invoice. It showed up as a strained relationship and a weekend of wasted labor. Now I require a written order confirmation for every line item, including promised delivery dates. If a supplier can't commit it in writing, it doesn't go into my schedule.

Step 6: Review final specs without distractions

This is the mistake that inspired me to write this article. I was closing out a large purchase of steel grating, and I opened the PO in Chrome. Instead of reviewing, I went down a rabbit hole researching how to block websites on Chrome so I'd stop refreshing a sports site. By the time I clicked back to the order, my cursor had been in the mesh-size field, and I'd unknowingly selected a much finer mesh than the application called for.

The material arrived looking nearly identical—until we measured the open area. Airflow was below spec. The batch was rejected: $2,100 in material, plus a week of delay, all because I wasn't paying attention at the final review.

Now, my last step is boring and deliberate. I close all irrelevant browser tabs, print the PO, and read it line by line. If I can, I pass it to someone else for a second read. That one habit has caught 47 potential errors in the past 18 months—most of them small, a few of them painful.

Last-Minute Checks (and what I still see go wrong)

Even experienced buyers make a few recurring mistakes:

• Assuming the bearing bar spacing will "probably" line up with the supports. Check the drawing.
• Ordering stainless steel because it "sounds better," without confirming the environment actually requires it. That's an unnecessary TCO bump.
• Not confirming deflection limits for fiberglass grating in high-traffic areas.
• Multi-tasking during purchase. I once tried to order replacement panels and fix a slow-fill toilet fill valve in the same afternoon. I mixed up two line items and my restock arrived short. Focus on one purchase at a time; your total cost includes your own attention.

That last one sounds trivial until you're the one explaining a two-week schedule slip. Every dollar you "save" by rushing through contract reviews can multiply into delays, reorders, and lost trust.

Choose the "cheap route" and you pay twice. I know because I've taken it.

Use these six steps on your next order for McNichols mesh, McNichols fiberglass grating, or any custom grating. Write down the environment, measure the span, match the material, calculate the TCO, get it in writing, and review without the browser tabs. That's not a "nice to have" process—it's the difference between turning a purchase order into an asset or into a problem.
