Buying Guide: How to Find the Best Price on 12 Gauge Strut Channel
When I need to find the best price on 12 gauge strut channel, my first step is always to understand what I am actually buying. Strut channel, sometimes called Unistrut, is a standardized formed structural system used to support everything from pipes and conduit to mechanical units. The “gauge” refers to the thickness of the steel, and 12 gauge is a common, robust choice for many industrial and construction applications. It is thick enough to provide significant load-bearing capacity without being overly heavy or expensive like thicker gauges. Knowing this helps me avoid buying something too flimsy or paying for overkill.
My next focus is on the finish. For most of my indoor projects, a standard galvanized finish is perfect. It offers decent protection against rust in non-corrosive environments. If I am working in a warehouse or a mechanical room, this is my go-to. However, if the project is for an outdoor application or in a damp environment like a parking garage, I look for a hot-dipped galvanized finish. This process coats the steel in a thicker layer of zinc, providing much better corrosion resistance. It might cost a bit more upfront, but it saves me from having to replace rusted channels in a few years. I always match the finish to the job’s environment to get real value.
Price is obviously a huge factor, but I have learned the hard way that the cheapest option is not always the best value. I start by comparing prices from big-box home improvement stores, specialized electrical and industrial suppliers, and online metal retailers. The per-foot price can vary wildly. I also pay close attention to bundle deals. Often, buying a 10-foot bundle or a full 20-foot length is significantly cheaper per foot than buying individual shorter pieces. If I have a large project, buying in bulk is the easiest way to get the best price on 12 gauge strut channel. I also check if the price includes shipping, as heavy metal channels can have high freight costs that wipe out any savings from a low sticker price.
Finally, I consider the brand and the supplier’s reputation. There are established brands in the industry known for their consistency and quality control. A slightly cheaper, no-name brand might have imperfections, inconsistent hole patterns, or a weaker galvanization that can cause problems during installation. I read reviews and ask other contractors for their opinions. A reliable supplier with good customer service is also worth its weight in gold, especially if an order is wrong or delayed. For me, the best value is a combination of a fair price, a quality product that meets the project’s demands, and a smooth purchasing experience from a trustworthy source.
Frequently Asked Questions
What is the actual thickness of 12 gauge strut channel?
This is a common point of confusion. The gauge system for steel does not translate to a precise, round number. A 12 gauge strut channel has a nominal thickness of approximately 0.1046 inches, which is just over 1/10 of an inch. It is helpful to know this exact measurement, especially when comparing it to metric equivalents or when the structural calculations for your project require precise data. Do not assume it is a simple fraction; confirming the decimal thickness ensures you are getting the strength you are paying for.
Can I use 12 gauge strut for overhead plumbing or electrical conduit?
Absolutely. In fact, this is one of its most common uses. The 12 gauge thickness provides excellent strength for supporting heavy pipes, multiple runs of electrical conduit, and even HVAC ductwork from ceilings or walls. The key is to follow the manufacturer’s load tables and use the appropriate fasteners and fittings. Always make sure your hanging points, like beam clamps or concrete anchors, are rated for the total weight you are suspending. The channel itself is strong, but the entire assembly is only as strong as its weakest part.
What is the difference between galvanized and pre-galvanized finish?
This is a critical distinction for longevity. “Pre-galvanized” typically means the steel sheet was coated with a thin layer of zinc before it was roll-formed into the strut channel shape. This coating is thinner and can be vulnerable at the cut edges. “Galvanized” or “hot-dipped galvanized” means the formed strut channel was dipped in a bath of molten zinc, creating a much thicker, more durable coating that covers the entire piece, including the edges. For any outdoor or corrosive environment, I always insist on hot-dipped galvanized to ensure the best price on 12 gauge strut channel translates to a long-lasting installation.
How do I cut 12 gauge strut channel cleanly?
You have a few good options. A metal-cutting bandsaw is my preferred method as it gives a very clean, square cut with minimal burrs. A reciprocating saw with a good bi-metal blade will also get the job done, though the cut might be rougher. An angle grinder with a cut-off wheel is fast and effective, but it throws a lot of sparks and can leave a significant burr that you will need to file down. No matter which tool you use, always wear appropriate safety gear like gloves and eye protection. After cutting, I always deburr the sharp edges with a file for safety and a professional look.
Is there a standard hole spacing for strut channel?
Yes, there is a common industry standard. Most 1-5/8″ wide strut channel you will find has holes spaced every 1-3/4 inches along its length. This standardized spacing is what makes the system so versatile, as all the nuts, beam clamps, and other accessories are designed to fit this pattern. However, it is always a good idea to double-check the product specifications before you buy, especially if you are sourcing from a new supplier, to ensure compatibility with your existing hardware.
