McNichols Steel, Plank Grating, Glass Railing Sourcing, and Baker Scaffold Rules: The 6 Questions I Actually Ask

I'm the office administrator for a 45-person company—I manage about $80K a year in supplier spend across eight regular vendors, and I report to both our operations lead and our finance manager. I don't design anything. What I do is catch the stuff that falls between the spec sheet and the invoice, and that's where almost every metal-supply headache starts.

Facilities and trade clients ask me the same questions over and over. Below are the six I field most often when orders run through McNichols or comparable metal distributors. I've tried to give the answers I'd actually give a colleague over coffee—not the polished version.

1. What does McNichols actually supply, and how is it different from a regular distributor?

McNichols is a metal products distributor and fabricator. The catalog is wide—bar grating, wire mesh, perforated panels, structural shapes, cladding, handrail and stair systems, elevator components, roofing and siding panels, formwork, scaffold products. The part that trips people up is that they're not just a warehouse pulling boxes off a shelf. They cut, fabricate, and support private-label and OEM runs. So when a spec sheet mentions "McNichols steel," it's usually shorthand for a specific product line—not a single material. Ask which published grade and finish is being quoted: ASTM A36, A1011, hot-dipped galvanized, mill finish. If the quote doesn't say, don't send the PO. That's the first place the paper trail falls apart.

2. When should I specify McNichols plank grating instead of regular bar grating?

McNichols plank grating is the tighter, plate-style grating—closely spaced load bars or interlocked planks that give you a more continuous walking surface. Regular bar grating is open steel grid. If a project has wheeled carts, pallet jacks, or anything that needs a flatter surface, plank grating is the right call. Otherwise the wheels catch on the bars and start bending things.

We learned this in October 2022. I quoted regular bar grating for a maintenance aisle and the customer's pallet jack put a sag in it inside a week (should mention: narrower aisle, heavier cart than we'd assumed—I hadn't asked). The replacement order ate about $4,800 out of our budget for a job that should have shipped once. If a spec says "plank grating," it means plank grating. Confirm the load direction before you order—if the supplier can't tell you which way the planks carry load, they're selling you a generic grid wrap.

3. What do I need to verify before sourcing glass railing for an outdoor job?

Glass railing sourcing is 20% glass and 80% everything around the glass. Three checks before you commit:

Glass type. Tempered or laminated—most commercial guard applications call for laminated per IBC 2407, and outdoor installations have wind-load considerations that shift the thickness. If the vendor quotes "glass panels" without specifying IBC-referenced construction, ask again.

Height and spacing. Minimum guard height is typically 36 inches (higher in some jurisdictions and for certain occupancies). A 4-inch sphere should not pass through any opening in the guard.

Base shoe and anchoring. This is where cheap quotes hide. Ask for a photo or detail of the base shoe and the anchor bolt schedule. If the supplier only shows glass, walk.

4. How do I compare handrail systems wholesale quotes without getting burned?

Wholesale quotes look cheap because the post is the cheap part. Brackets, connector fittings, anchor bolts, and fill-type material (cable, glass clamps, or vertical pickets) are where the money hides. Demand an itemized BOM—every post, every connector, every anchor—and then reconcile it against the drawings. Roughly nine times out of ten the first quote will omit a connector or anchor type that the drawings clearly need.

Also separate the finish in the quote. Hot-dipped galvanizing versus powder-coating is not a cosmetic line item; the price gap is real and the lead times differ. If a supplier won't break the finish out, they're blending the price to look competitive on the summary sheet.

5. What are the actual Baker scaffold compliance requirements?

Baker scaffolds are the rolling, mobile units you see on interior work—casters, decked work platform, sometimes with guardrail kits. They fall under OSHA 29 CFR 1926.451. The practical checklist:

(1) Full-width decking on the platform, with toe boards;
(2) Guardrails on the three exposed sides—top rail around 42 inches, midrail around 21 inches;
(3) Casters locked before anyone climbs on;
(4) Height-to-base ratio within the manufacturer's stated limit (commonly 4:1 without outriggers);
(5) Rated capacity posted on the unit, and a legible label plate.

Inspection tends to focus on the two that get skipped: locked casters and the label plate. If I remember correctly, we got a small tag on a jobsite visit for the caster—don't quote my exact dollar figure, but it was enough to make me put a photo of the label on our order checklist going forward.

6. What one document request saves the most money?

Material Test Reports (MTRs)—also called mill certificates. Ask for them before the order ships, not after. The MTR traces heat number, chemistry, and mechanical properties back to the mill so you can prove the material meets the required ASTM grade. No MTR, no proof, no claim.

Our sister department once reordered $4,200 of galvanized grating because the coating thickness on delivery didn't match the specified gauge. The mill cert would have caught that mismatch in ten minutes before anything shipped. Looking back, I should have put "MTR required with shipment" as a standard clause on every PO. It's on there now.

The pattern behind all six: the cheap quote is almost never cheaper. Five minutes on the front end asking for the grade, the load direction, the finish, or the certification beats five days of rework. That's not a slogan—it's the invoice talking.
