Hey there, if you\u2019re reading this, you\u2019re probably deep in the weeds of sourcing steel structural products and wondering the big question: do all these random, not-your-standard-beam-or-column steel bits even need galvanizing? Spoiler alert\u2014 I\u2019ve been on the other side of that desk, slinging these \u201cother\u201d steel structural products for years, and let me tell you, the answer isn\u2019t a simple yes or no. It\u2019s way more nuanced than that, and today I\u2019m breaking it down like we\u2019re chatting over a coffee (no stuffy engineering jargon, promise). Other Steel Structural Products<\/a><\/p>\n

<\/p>\n

First off, let\u2019s get on the same page about what I even mean by \u201cother steel structural products.\u201d You know the stuff\u2014 not the big I-beams for skyscrapers or H-columns for bridges. Think edge trim for metal building exteriors, custom steel brackets for attaching solar panels to residential roofs, pre-fabricated steel flashing for concrete foundation joints, utility crossarm attachments for power lines, handrail brackets for public park walkways, and those weird little steel gusset plates that hold trusses together when standard metal trusses aren\u2019t cutting it for a custom shed. Yeah, that\u2019s the \u201cother\u201d stuff\u2014 the parts that are actually the unsung heroes of any construction project, but everyone forgets to ask about their corrosion protection until it\u2019s too late.<\/p>\n

I get why people are confused about galvanizing, too. If you work with steel day in and day out, you\u2019ve probably heard of hot-dip galvanizing as the go-to corrosion fix for structural steel. It\u2019s that process where you dip steel into molten zinc, so a thick, tough zinc coating sticks to the surface, right? It creates a barrier between the steel and the elements, and even if the coating gets scratched in a spot, the zinc sacrifices itself a little to protect the exposed iron underneath. For big, high-load structural members like bridge beams, galvanizing is non-negotiable. But does that rule apply to every random bracket or trim piece? Let\u2019s dive into when it\u2019s a must, when it\u2019s optional, and when it\u2019s actually a waste of cash.<\/p>\n

Let\u2019s start with the times galvanizing is non-negotiable for our \u201cother\u201d steel structural products. First, any product that\u2019s going to be exposed to the outdoors long-term, no exceptions. If your customer is using edge trim on a metal barn that\u2019s in the humid South, or solar panel mounting brackets on a residential roof in Florida where salt air lingers near the coast, galvanizing isn\u2019t a \u201cnice-to-have\u201d \u2014 it\u2019s how you avoid a call back 2 years later saying the trim is rusting through and staining their siding. I learned this the hard way early on, when we sold a batch of uncoated steel utility crossarm attachments to a local power company that installed them in a marshy area. Six months later, they were calling us panicking because the steel was rusting so bad the crossarms were sagging. We ate the cost of replacement, figured out fast that any steel part exposed to moisture, humidity, or airborne salt needs that zinc layer.<\/p>\n

Then there\u2019s products that are in contact with other materials that cause corrosion. Wait, steel and aluminum don\u2019t play nice together, right? If you\u2019re making a steel handrail bracket that\u2019s going to be bolted to an aluminum deck, or a flashing piece that\u2019s sitting on top of concrete that has extra high alkali levels (super common in new construction concrete), galvanizing is key. That\u2019s called galvanic corrosion, by the way\u2014 when two different metals touch in the presence of moisture, one eats the other. Zinc is more reactive than both steel and aluminum, so when it\u2019s coated on your steel, it prevents that galvanic reaction from taking hold. I\u2019ve had clients skip galvanizing on a bracket meant for a concrete patio, and within a year, the bracket started rusting and leaving orange stains on the patio pavers. That\u2019s a headache no one wants to deal with, so galvanizing here is a no-brainer.<\/p>\n

Now, the times when galvanizing is actually optional, and we\u2019re not just trying to upsell you. Wait, upsell? C\u2019mon, I\u2019m not here to waste your money. If a product is going to be inside a climate-controlled space, that\u2019s a huge call. Let\u2019s say it\u2019s a custom steel bracket holding shelves in a warehouse that\u2019s temperature-regulated, no leaks, no high humidity. Or a steel gusset plate used inside a pre-fab office building, where it\u2019s never going to see rain or harsh conditions. Here, you can get away with other cheaper corrosion protection, like powder coating. Powder coating is durable, comes in fun colors if your customer cares about aesthetics, and it\u2019s way less expensive than galvanizing. I\u2019ve had a client who needed custom steel brackets for indoor retail shelving, and galvanizing would\u2019ve added 30% to their cost. We recommended powder coating instead, they saved a ton of money, and there hasn\u2019t been a single rust issue in the three years they\u2019ve had them installed.<\/p>\n

Another time galvanizing isn\u2019t necessary is for products that are going to be painted or coated immediately after installation, and the environment they\u2019re in isn\u2019t harsh. Let\u2019s say it\u2019s a steel trim piece that\u2019s going to be installed on a house, and the siding is going to be painted right away. Or a handrail bracket that\u2019s going to be painted to match the handrail. As long as that top layer of paint adheres properly (galvanizing can sometimes mess with paint adhesion if you don\u2019t prep it right, fun fact), then you don\u2019t need the zinc layer. I\u2019ve even had a few clients that prefer to do their own painting, so they buy uncoated steel structural products, paint them on-site, and that works for their needs. Just make sure they\u2019re not using the product in a spot that\u2019s going to get a lot of rain or moisture, where the paint could chip and expose the steel.<\/p>\n

Wait, but hold on\u2014 there\u2019s a third category, too, where galvanizing is technically optional but actually smart, even if the environment seems mild. Let\u2019s take a custom shed kit we worked with a few years back. The shed was going to be in a backyard, not right on the coast, not in a super humid area. The client thought they could skip galvanizing and just paint all the steel parts. But a year later, they called us saying the gusset plates holding the shed trusses together had small rust spots, and they were worried the trusses would start to warp. They ended up repainting, but if we\u2019d galvanized the gusset plates upfront, they wouldn\u2019t have had that problem. Why? Because even \u201cmild\u201d environments\u2014 a backyard, a residential rooftop, a sidewalk handrail\u2014 they get rain, snow, condensation, even little splashes from the sprinkler. That\u2019s enough moisture to cause rust over 5, 10, 15 years, which is the lifespan most customers expect from their steel products. Galvanizing adds a little upfront cost, but it extends the product\u2019s lifespan by decades. That\u2019s a big selling point, and something I always bring up when a client is on the fence.<\/p>\n

Now, let\u2019s talk about the things that a lot of people get wrong about galvanizing for \u201cother\u201d steel structural products. First, it\u2019s not just for big steel members. I\u2019ve seen guys skip galvanizing on tiny, seemingly insignificant parts like hardware brackets for outdoor gates, and those rust through in 2-3 years, which is frustrating. Second, galvanizing isn\u2019t just one size fits all. There\u2019s different thicknesses of zinc coating\u2014 standard galvanizing is good for most outdoor use, but if a product is going to be in a really harsh environment, like a coastal area or a chemical plant, you can get a thicker galvanized coating that lasts even longer. I always ask my clients about their end-use environment first, that\u2019s how we figure out what\u2019s right for them.<\/p>\n

Another myth I hear all the time: galvanizing is too expensive for small parts. Yeah, if you\u2019re only making 10 brackets, the per-part cost of galvanizing is a little higher, but if you\u2019re ordering a bulk run, that extra cost is negligible. And when you compare it to the cost of replacing a rusted part down the line, it\u2019s way worth it. I had a client a few months ago that ordered 500 uncoated steel flashing pieces for a roofing project, and within 18 months, they had to replace 200 of them because of rust. The cost of replacing those was more than the cost of galvanizing all 500 pieces upfront. That\u2019s a mistake no one wants to make.<\/p>\n

So, putting this all together: when do your \u201cother\u201d steel structural products need galvanizing? If they\u2019re exposed to outdoor elements (moisture, humidity, salt air, snow), if they\u2019re in contact with other metals that cause galvanic corrosion, if they\u2019re not going to be painted or otherwise coated right away, or if their end-use environment is harsh, then yes, galvanizing is probably the right call. If they\u2019re going to be in a climate-controlled indoor space, if they\u2019re going to be painted immediately post-install, and the environment is mild, then you can skip it and go with a cheaper alternative like powder coating. And if you\u2019re on the fence, ask yourself: how long does my customer expect this product to last? If it\u2019s 10+ years, galvanizing is almost always a safe bet.<\/p>\n

At the end of the day, I\u2019m in this business because I want my clients to get steel products that work for their needs, not just what\u2019s cheapest for me. I\u2019ve seen the good, the bad, and the ugly when it comes to corrosion on these \u201cother\u201d steel parts, and I can tell you that the number one mistake people make is either overgalvanizing when they don\u2019t need it (wasting money) or undergalvanizing when they do need it (costing them repairs and headaches).<\/p>\n
