If you’ve ever worked in industries like oil and gas, marine engineering, petrochemical processing, or heavy manufacturing, you know that not all materials are one-size-fits-all. A standard steel plate might be strong enough for a basic structural part, but when you need a material that resists corrosion from harsh chemicals, stands up to extreme pressure at sea, or conducts heat evenly across a large surface, you start looking for something that combines the best of two (or more) metals. That’s where explosive clad plates come in, and as someone who’s supplied these specialized materials for over a decade, I get asked one question more than any other: Can explosive clad plates be customized according to specific requirements? Explosive Clad Plates
The short answer is a resounding yes—but the longer, more detailed answer is where you’ll find the real value. Customization isn’t just a buzzword in our industry; it’s the backbone of how explosive clad plates solve problems that traditional single-metal materials can’t touch. Let me break down what that customization actually looks like, how it works, and why it matters for your project.
First, let’s refresh what explosive clad plates are, for anyone new to the space. At their core, they’re two (or more) distinct metals bonded together permanently using controlled explosive force. It’s not like gluing two pieces of metal together, where the bond can fail under stress or extreme conditions. Instead, the process creates a metallurgical bond at the interface of the two metals—meaning the atoms of each metal fuse together at a molecular level. That bond is strong enough to handle the same stress, temperature, and environmental conditions as the parent metals themselves. But to get that right, the process has to be tailored to exactly what you need.
When a client comes to us with a project, the first thing we talk about isn’t just “metal A and metal B.” It’s their specific operating conditions. For example, a petrochemical plant might need a clad plate for a reactor vessel that has a carbon steel backplate (cheap, strong, and easy to fabricate) and a 316L stainless steel cladding (resistant to corrosion from sulfuric acid and other harsh chemicals). But maybe their reactor is larger than standard plates, or they need a different grade of stainless steel that can handle higher temperatures, or they want a layer of Inconel instead of stainless for even more corrosion resistance. All of that is customizable.
Let’s start with the basics: choosing the right metal combination. Standard common combinations are carbon steel + stainless steel, carbon steel + aluminum, carbon steel + copper, and titanium + steel. But we’ve worked with clients on everything from bronze + steel for marine components that need wear resistance, to Hastelloy + steel for high-temperature, high-pressure chemical processing. The key here is matching the cladding material to the specific environment. If you’re working in a saltwater marine application, pure titanium cladding is non-negotiable for resisting salt corrosion, but if you’re working in a milder chemical environment, a lower-grade stainless steel might work just fine—and at a lower cost. Customization here means picking the exact metal pair that balances performance and budget, not just using a pre-made standard combination.
Next, size and dimensions. Standard explosive clad plates often come in sizes like 10ft x 4ft or 12ft x 5ft, but most large-scale projects need plates that are bigger, smaller, or have precise, non-standard dimensions. A client building a 50,000-barrel oil storage tank might need clad plates that are 20ft long to reduce the number of seams they have to weld, which cuts down on fabrication time and costs. Or a small-scale chemical reactor might need a 2ft x 2ft custom-sized plate for a complex internal component, where a standard plate would require too much cutting and waste. We can cut explosive clad plates to almost any dimension, as long as we account for a small margin around the edge of the clad layer to make sure the metallurgical bond isn’t compromised during cutting. We can also drill precise holes, machine edges, or even pre-form curved shapes for projects that need bent clad plates—something that’s impossible with solid stainless steel, because solid stainless would be too expensive and too heavy for large components.
Then there’s thickness. This is where a lot of people get surprised. The backplate (the structural layer) and the cladding layer can each be customized to almost any thickness, as long as the ratio between them makes sense for the explosive bonding process. For example, a common cladding thickness for chemical reactors is 3mm to 6mm, but we’ve done cladding as thin as 1mm for small components that need light weight and corrosion resistance, and as thick as 50mm for projects that need extreme wear resistance. The backplate can be as thin as 6mm or as thick as 200mm, depending on how much structural strength your project needs. A client building a heavy-duty mining component, for example, might need a 150mm thick carbon steel backplate for strength and a 10mm thick high-chromium cladding for wear resistance, which is a custom combination we can produce exactly to those specs.
Another big area of customization is surface finish. You might think the surface finish doesn’t matter, but it can make a huge difference for how a component performs. For a food and beverage processing plant, the cladding layer needs a smooth, sterile surface that’s easy to clean and meets food safety standards. We can do a mill finish, which is the raw surface after bonding, but also polished finishes of any grit number, brushed finishes, or even electropolished finishes for applications that need maximum hygiene. For marine components, sometimes a slightly rough, non-slip surface is needed, so we can adjust the finishing process to get exactly that.
But the real magic of customization comes when you need to solve a specific problem that standard products can’t. Let me give you an example from a project we did a few years back for a wind farm operator. They needed large base plates for their offshore wind turbine foundations, which have to sit on the seabed for 20+ years, exposed to saltwater, extreme pressure, and movement from waves and wind. Standard carbon steel base plates would corrode too quickly, and solid stainless steel base plates would be so heavy that they’d make the turbine foundation unstable and way too expensive. The solution? A custom explosive clad plate made from a 180mm thick carbon steel backplate (for structural strength and low cost) and a 12mm thick duplex stainless steel cladding (for unmatched saltwater corrosion resistance). We also had to make the plates in 18ft x 8ft dimensions, which was bigger than any standard plate available, and machine custom bolt holes to exact specs for the turbine legs. That project wouldn’t have worked with any off-the-shelf clad plate—it had to be built exactly to their needs.
I’ve also worked with a petrochemical client that was dealing with corrosion in their hydrogen processing units. The standard stainless steel clad plates they were using were failing after just 2 years, because hydrogen permeated the stainless layer and caused hydrogen embrittlement in the carbon steel backplate. We developed a custom clad plate with a middle layer of nickel alloy, which acts as a barrier to hydrogen, between the carbon steel backplate and the stainless steel cladding. That three-layer custom clad plate solved their problem, and now their units are still running after 5 years with no corrosion issues. That’s the kind of innovation customization enables—taking the limitations of two metals and adding a third to solve a unique problem.
Now, I know some of you might be wondering about quality when you customize—how do you make sure a custom clad plate is as strong and reliable as a standard one? That’s a fair question, and it’s something we take very seriously. Every custom clad plate we produce goes through a rigorous testing process to verify the metallurgical bond. We do ultrasonic testing to check for any gaps or weak spots at the interface, peel tests to ensure the bond strength meets industry standards, and bending tests to make sure the plate can be fabricated without the bond failing. We also provide full material certifications, so you can be sure the plate meets all your project’s specifications and codes, like ASME, API, or ISO.
Of course, there are limits to customization, and that’s something we always make clear to clients. For example, not every metal combination can be explosive bonded—some metals have incompatible atomic structures that make a strong bond impossible. We’ll always be upfront with you if a custom metal pair isn’t feasible, and we’ll work with you to find an alternative that meets your needs. Also, the larger the plate, the more we have to adjust the explosive process to ensure uniform bonding across the entire surface, but that’s not a barrier—it’s just part of the customization process we’ve mastered over the years.
So, if you’re working on a project right now where standard materials aren’t cutting it—whether you need a specific metal pair, a unique size, custom thickness, or a tailored solution for harsh conditions—explosive clad plates are absolutely the way to go, and they can be built exactly to your specifications. As someone who’s been in this industry for years, I’ve seen custom clad plates solve problems that engineers thought were unsolvable, from offshore wind foundations to pharmaceutical processing equipment to mining components that stand up to heavy wear. If you’re tired of settling for materials that are close, not exactly right, then it’s time to talk about custom explosive clad plates.
