McNichols Grating & Wire Mesh: 7 Questions You Need Answered Before You Buy

What exactly does McNichols offer — and what should I look for when choosing between grating, mesh, and perforated metal?

McNichols is a major supplier in the industrial grating and metal mesh space. If you've been searching for mcnichols stair treads or mcnichols wire mesh, you've found the right place. Their catalog is broad — metal grating, fiberglass grating, wire mesh, perforated panels, plank grating, stair treads, architectural mesh, and more.

In my experience reviewing specifications for about 200+ unique orders annually, the choice comes down to three factors: load requirement, corrosion environment, and budget. Here's the thing: don't assume metal is always better. Fiberglass grating is surprisingly strong and won't rust. But if you need a welded steel grating for a heavy-duty mezzanine, metal is the way to go.

For stair treads specifically, McNichols offers options like serrated surfaces for slip resistance and different nosing styles. The key question to ask yourself: is this for a high-traffic industrial environment or a light-duty maintenance access point? The answer changes your specification.

"I've only worked with mid-range industrial orders. If you're specifying for a food processing plant with strict hygiene requirements, your material choice might differ significantly."

Can I order small quantities from McNichols? I'm a small contractor, not a big manufacturer.

Short answer: yes, generally. McNichols is known in the industry for not having punishing minimum order quantities. That's not to say every product is available in single-unit quantities — a custom-fabricated architectural mesh panel is a different story from a standard 2' x 4' steel grating panel.

From my perspective, this is one of their strengths. When I was starting out, the vendors who treated my small orders seriously are the ones I still use. McNichols seems to understand that today's small contractor could be tomorrow's regular specifier.

The way I see it: small doesn't mean unimportant — it means potential. If you're ordering a few stair treads for a small renovation, you should expect the same quality and service as a larger buyer. Not all suppliers get this right. McNichols does a decent job based on my experience.

How do I know if I'm getting the right specification for stair treads?

Don't hold me to this as a universal rule, but here's a practical starting point for mcnichols stair treads:

• Load requirement: Ask about the intended live load. Standard commercial stairs often use 300 psf. Industrial might need 500 psf or more.
• Material: Steel for strength and cost-effectiveness. Aluminum where weight or corrosion is a concern. Fiberglass for chemical resistance.
• Surface: Serrated or grit-top for slip resistance. A smooth surface might look nicer but is a liability in wet conditions.
• Nosing: Does it need a flat front edge, or will a standard angle nosing work?

The mistake I see most often: ordering based on price without clarifying the nosing style or slip resistance. It's a communication failure waiting to happen. I've seen a specification for 'stair treads' that arrived with a flush nosing when a projected nosing was expected. Costly redo. Every contract should include a dimensioned drawing or at least a clear spec sheet.

What about mcnichols wire mesh — how do I pick the right opening size and wire diameter?

This is where people get lost. Wire mesh is deceptively simple: it's just wires crossing each other. But the combination of opening size, wire diameter, and material makes it a technical product.

Here's a rule of thumb: smaller openings and thicker wires mean more strength, less visibility, and higher cost. For safety barriers, you probably need mesh that prevents a 4-inch sphere from passing through. For architectural screening, the aesthetic might dictate a larger opening with thinner wires.

McNichols stocks a wide range. The question isn't 'do they have it?' — it's 'which variant?' In my opinion, the most overlooked spec is the edge treatment. A welded wire panel with a framed edge is much stiffer than a cut-to-size piece. If you're installing it as a fence or guard, the edge treatment matters more than you think.

"I said 'standard wire mesh.' They heard '6x6, W1.4/W1.4.' Result: material that was too light for the load requirement. We both used the same words, meaning different things."

Is there a quality difference between McNichols and generic suppliers?

Probably. Not all suppliers are created equal, and in my experience, McNichols has a reputation for consistency. That said, I'm not saying the cheapest option is always bad. It's about risk tolerance.

In Q1 2024, we received a batch of grating from a new vendor where the bar spacing was visibly off — 1.25 inches average against our 1.1875-inch standard spec. Normal tolerance is +/- 1/16 inch. The vendor claimed it was 'within industry standard.' We rejected the batch, and they redid it at their cost. Now every contract includes specific tolerance language.

McNichols, to their credit, has clear spec sheets and tolerances published. That doesn't mean they're perfect — no supplier is. But it means you can hold them accountable. With a generic supplier, you might not have that documentation to fall back on.

Will my order from McNichols arrive ready to install, or does it need fabrication?

This depends on what you order. Standard catalog items — stock grating panels, stair treads, wire mesh rolls — usually ship quickly and are meant for direct use. Custom fabricated items — cut-to-size panels, notched or bent parts, architectural mesh with specific framing — require lead time.

Roughly speaking, expect 1-2 weeks for standard items and 4-6 weeks for custom fabrication. Don't hold me to exact timelines — call for current lead times — but that's the ballpark from my experience.

The gotcha: some customers assume all products are stock items. A perforated panel with a specific hole pattern and sheet size? That's likely a fabrication job. Always clarify before ordering.

What's one thing people don't ask about — but should — when buying from McNichols?

The packaging and handling for long, thin items like stair treads or plank grating. I've seen treads arrive with bent edges because they weren't adequately bundled or supported during shipping. It's not a common problem, but it happens.

Ask your sales rep: how will this be packed for shipment? Can it be crated or strapped to a pallet? Is there a risk of damage in transit? For a $200 order, standard packaging is usually fine. For an $18,000 project, the extra $200 for proper crating is a no-brainer.

Another thing: check the material certifications if your project requires them. Some applications — like food processing or pharmaceutical — need specific material traceability. McNichols can provide mill certs, but you have to ask. Don't assume it comes standard.
