When I first started my custom medium-sized metal welded parts shop ten years ago, I mostly worked with local construction companies—think handrails for commercial buildings, brackets for warehouse equipment, and basic support frames for new retail locations. Back then, I rarely thought about the energy industry, let alone the unique, rigorous needs that sector would have for parts that are as reliable as they are precisely built. Today, though, I’m fielding calls and messages almost weekly from energy project managers and design engineers asking a simple question: can your custom medium-sized metal welded parts actually work in our operations? The short answer is a resounding yes, but the longer, more specific story of how we’ve adapted our process, materials, and quality checks to meet energy industry standards is what I want to share with you today. Custom Medium-Sized Metal Welded Parts
Let’s start with what medium-sized metal welded parts even mean for context here. I define medium-sized as components that are roughly 1 to 10 feet in their largest dimension—big enough to handle substantial load or pressure, but not so large they require on-site fabrication or specialty shipping that drives up costs and lead times. For the energy sector, these parts fill critical gaps that oversized bulk components or tiny off-the-shelf parts can’t: they’re the backbone of modular piping assemblies, skid-mounted pump supports, wind turbine tower access platforms, solar panel racking for large utility farms, and the support brackets that hold electrical transmission line hardware in place.
The energy industry’s requirements are non-negotiable, and that’s why so many of our long-term clients in this space stick with us instead of generic part suppliers. Unlike construction, where a minor weld flaw might only cause a cosmetic issue or a small structural wobble, an imperfection in a part for energy can lead to downtime that costs tens of thousands of dollars per day, or even safety risks for on-site workers. That’s why we’ve spent years refining every step of our custom welding process to align with key energy industry standards, like those set by the American Petroleum Institute (API) for oil and gas, the International Electrotechnical Commission (IEC) for renewable energy, and the American Welding Society (AWS) for all structural welding.
Take oil and gas midstream operations, for example. These facilities rely on skid-mounted pump assemblies that move crude oil, natural gas, or refined products between pipelines and storage tanks. A medium-sized welded part here might be the frame that holds the pump, the support brackets that align connected piping, or a mounting plate for pressure sensors. A few years back, we landed a contract to build 120 custom pump skid support frames for a pipeline expansion project in the Permian Basin. The project engineer initially asked for a standard, off-the-shelf frame, but when we explained that off-the-shelf parts are designed for general use, not for the corrosive, high-pressure conditions of oil and gas, they agreed to go custom. We used carbon steel alloyed with chromium for extra corrosion resistance, ran every weld through magnetic particle testing to catch even micro-cracks that would be invisible to the naked eye, and adjusted the weld bead profile to reduce stress points where metal could crack under repeated pressure cycles from the pump. That order didn’t have a single failure on site, and the client has come back to us for three more expansions since then. It’s proof that custom medium-sized welded parts don’t just work in energy—they work better than generic parts for the specific needs of these operations.
Renewable energy is another space where our parts are making a big impact, and it’s a sector that’s growing faster than almost any other in energy right now. Wind turbine manufacturers, for example, need medium-sized welded components for their tower access ladders, nacelle support brackets, and blade pitch control mounts. These parts have to survive extreme conditions: wind speeds over 100 mph, temperature swings from -40°F in northern climates to 120°F in desert regions, and constant vibration from turbine rotation. A few months ago, a wind farm developer in the Great Plains reached out to us because their current parts supplier was delivering welded access ladders that were failing in just two years—way before their 10-year service life requirement. We worked with their engineering team to redesign the ladder: instead of using standard steel, we switched to hot-dip galvanized steel, which creates a protective zinc layer that prevents rust even when exposed to rain, snow, and the dust that’s common in the Plains. We also adjusted our welding technique to use a pulsed MIG process, which produces a smoother, more uniform weld that’s less likely to develop cracks from the constant vibration of the turbine. Since installing our redesigned ladders, the developer hasn’t reported a single failure, and they’re now using our parts for all 32 new turbines in their upcoming phase.
Solar energy utility farms are another area where our custom parts come into play. Large-scale solar farms need heavy-duty racking systems that can support hundreds of pounds of solar panels, hold up to 200 mph wind loads, and resist corrosion from salt air if they’re located near coastal areas. Most off-the-shelf racking is designed for small residential or commercial arrays, not the utility-scale projects that stretch across hundreds of acres. For a solar farm in Arizona that’s expanding by 500 acres, we built custom welded support brackets for their single-axis tracking systems—these brackets hold the motors that tilt the panels to follow the sun throughout the day. We used a high-strength low-alloy (HSLA) steel that’s lighter than standard carbon steel but just as strong, which reduced the overall load on the tracking system and cut down on material costs for the project. We also added a zinc-rich paint coating to the welds, which provides an extra layer of protection against the intense UV radiation and high temperatures of the Arizona desert. That project’s brackets have been in place for 18 months now, with no signs of corrosion or structural stress.
But it’s not just about building parts that work—our biggest value for energy clients is the flexibility that comes with custom manufacturing. Energy projects rarely go exactly according to plan. A sudden design change, a last-minute material requirement, or on-site measurements that don’t match initial blueprints are all common. When a nuclear power plant in the Midwest needed custom welded containment vessel penetrations for a new control system upgrade, their original supplier couldn’t adjust the design when they realized the penetrations would need to fit a non-standard pipe diameter. We worked directly with their engineering team, modifying the weld fit-up and adjusting the material thickness to meet their exact specifications, all while sticking to their tight 6-week deadline. The penetrations have now been in operation for two years, with zero leakage or structural issues—something the client told us they couldn’t have achieved with a generic, one-size-fits-all part.
Of course, working in energy means we have to meet the strictest safety and quality standards, and that’s an area we’ve invested heavily in over the years. All of our welders are certified to AWS D1.1, API 1104, and IEC 61508 standards—those aren’t just pieces of paper on our wall; every single weld we produce is either visually inspected by our senior lead welder, tested with ultrasonic testing, or pressure tested, depending on the part’s application. We also keep meticulous records for every order: what material we used, which welder worked on each section, what tests were performed, and the results. That’s critical for energy projects, where regulators require full traceability of all components, especially in high-risk areas like nuclear or oil and gas processing.
I know there are still people out there who think medium-sized custom welded parts are too expensive, or that generic off-the-shelf parts are sufficient for energy operations. But let’s do the math: a $500 custom welded bracket that lasts 10 years costs $50 per year, while a $100 off-the-shelf bracket that fails every 2 years costs $50 per year too—plus you have to factor in the cost of labor to replace it, downtime for the operation, and potential safety risks. For a large energy facility with hundreds of these parts, that adds up to hundreds of thousands of dollars in savings over the life of the project. And for renewable energy, where every pound of weight reduction increases energy efficiency, custom parts that are optimized for strength and weight can actually improve a project’s overall performance.
I’ve been in this business long enough to see trends come and go, but the demand for reliable, custom welded parts in the energy sector is only going up. The International Energy Agency projects that global demand for oil and gas will stay strong through 2030, and renewable energy will grow by more than 50% in that same period. That means more pipelines, more wind turbines, more solar farms, more nuclear upgrades—all of which need medium-sized metal welded parts that are built to last.
