McNichols Steel & Wire Mesh FAQ: Quality Manager Answers on Cable Railing OEM, Bulk Siding, and Stair Costs

I've spent the last several years reviewing incoming metal orders for a building materials company—grating, wire mesh, railing components, panels, you name it. McNichols shows up in a lot of our bid docs, so I've developed a pretty detailed picture of their products, their tolerances, and where they'll make you pull your hair out. Here are the questions I get from contractors and purchasing folks, answered plainly.

Is McNichols steel a manufacturer or just a middleman?

Both, but mostly a value-added distributor. They stock grating, wire mesh, perforated panels, stair treads, and railing components—then cut, shear, or fabricate to order. For cladding and metal siding, they aren't rolling raw coil in-house; they source mill stock and process it. That distinction matters if you need custom sizes. A distributor can't invent a new alloy for you, and they're working from standard mill inventory. In my experience, the real strength is the range under one roof. McNichols steel catalogs are massive, and their inventory system usually shows actual stock levels, which helps when you're pricing a job on a Friday afternoon.

How does McNichols wire mesh hold up against cheaper online suppliers?

I've tested wire mesh from three suppliers in one quarter. The cheapest option came in with inconsistent wire diameter—spec said .120", measured .112". That might not sound like much, but it changes the open area and the fit of clips and framing. McNichols wire mesh, by comparison, came in comfortably within tolerance. The misconception is thinking all wire mesh is the same. It isn't. Open area, crimp pattern, edge treatment, and material grade change both load capacity and price. If you only compare per-square-foot price, you'll miss the difference. On one of our projects, the savings from a budget mesh got eaten entirely by rework because standard brackets didn't fit the openings.

Can I get custom cable railing OEM and private-label support from McNichols?

Yes, McNichols works with OEM and private-label accounts. If you're a wholesaler or railing system manufacturer, they can supply the components—stainless cable, swage studs, posts, handrail tubing—and you do the assembly and branding. What to watch: consistency. I've seen one batch of swaged studs spec out wrong, and that cost us roughly $22,000 in labor and delay when we had to sort and rework them. The lesson: ask for their written tolerance statement before committing. Also ask about packaging if you're selling direct to consumers. Their standard packing may or may not survive a parcel carrier.

Does McNichols actually sell bulk metal siding, or is that just a search term?

They do sell metal siding and roofing panels in bulk—usually corrugated, standing seam, and through-fastened profiles. But "bulk" in the B2B sense doesn't always mean mill-direct. McNichols will quote full bundles and truckload quantities, and pricing varies by gauge, finish, and volume. Don't hold me to this, but their siding pricing seems to move with the steel index. One thing I've learned: the biggest line-item savings often come from consolidating materials in one shipment. If you're already buying grating and stair treads, adding siding to the same order can cut freight cost per item significantly. It's tempting to think you can just compare unit prices, but freight, handling, and cut fees change the total.

What should a stair systems wholesale cost guide include?

Stair systems are where the "cheapest quote" trap bites hardest. A typical stair systems wholesale cost guide quotes the steel piece price only. When I priced a full set of interior steel stairs in Q1 2024, the material was roughly 55% of the installed cost—the rest was cutting, coping, welding, and fasteners. McNichols stair treads are priced per piece, but you need to factor in cut-offs, galvanizing (hot-dip, per ASTM A123/A123M), and engineering review if it's an egress stair. IBC requires uniform tread depth, and the local inspector will measure. For grating load tables, use the NAAMM Metal Bar Grating Manual (MBG-534) instead of a supplier's marketing sheet. The real question isn't "which supplier has the lowest per-pound price" but "which one can hold tolerances when the stairs get inspected."

Is McNichols' expedited delivery worth the extra cost?

This is the one place I've learned to stop being cheap. In March 2024, we paid an extra $400 for rush processing on a custom grating order. The alternative was missing a $15,000 event install. The "always order early" advice sounds good, but projects slip. The certainty of a confirmed expedite is worth money; an estimated lead time isn't a promise. If your job has penalty clauses, ask McNichols for a written ship date—not just "ships in 2 weeks." Their customer service can usually lock that in for a fee. In hindsight, I should have asked for written confirmations more often. Verbal promises don't survive disputes.

What quality checks should I run when a McNichols order lands?

The two things I always inspect: dimensions and coating. For galvanized products, check coating thickness and condition—we reference ASTM A123/A123M. For grating, verify bar spacing, bearing bar size, and overall length against the shop drawing. McNichols generally does good work, but receiving teams often accept "within industry standard" when the spec sheet is the actual contract. If something looks off, reject with photos and the spec line item. I once rejected a full pallet of custom panels because they arrived with sharp burrs that weren't specified to be deburred. That cost an extra 12 hours of hand finishing. Note to self: always put deburring in the spec, even when you assume it's standard.
