Our work has ranged from precision metal enclosures (enabling a major fuel distributor to roll out a new green technology) to sheet metal containers for ultrasonic cleaning (such as those created for a drive train manufacturer). We are skilled at large production runs of custom metal brackets, such as those we produce for a major Midwest distributor, as well as shorter runs for contract manufacturing. Marlin Steel sheet metal fabrications include:
- Hardware casings.
- Fan and light guards.
- Vacuum ducts.
- Side beds.
- Cam boxes.
- Box plugs.
- Telescoping sleeves for inner ducts as well as telescoping outer ducts,
and many other products.
We export to 36 countries using automated manufacturing techniques. Robotics are also used for our arc, MIG, TIG, and resistance spot welding to deliver a consistently strong and aesthetically satisfactory result.
Because of our machining capabilities, we are able to create custom tooling to maintain workflows and keep production both on schedule and on budget. Our milling and machining equipment includes machines from Haas, a renowned name in the industry.
We have extensive experience fabricating products using a wide range of materials, such as: aluminum, stainless steel, galvanized steel, titanium, and low carbon mild steel. We also have designed and fabricated products in Lexan, glass, laminates and plastic. Our engineering team can recommend the best raw material and finish to allow your parts to fulfill your objectives. Customers have a choice of finishes including chrome, nickel, plastic, epoxy, zinc, brass, Teflon, Nylon, Halar and more. Stainless-steel units can be electropolished and passivated for a shiny finish or delivered with a natural finish.
Some of the most common materials our customers choose include:
- Grade 301 Stainless: High strength. Excellent corrosion resistance. Useful for a wide variety of applications. Less corrosion resistant than 304 because it has lower chromium and nickel content and higher carbon, but if the material is not regularly exposed to high temperatures, saltwater, or other very corrosive conditions, 301 should be fine.
- Grade 304 Stainless: For most applications, 304 grade has the best combination of corrosion resistance, mechanical properties, and cost.
- Grade 316 Stainless: Corrosion resistant. Heat resistant. For high corrosion resistance in food, biomedical, marine, and heat exchanger applications, 316 can be worth the price difference. The resistance to solvents, chlorides, acetic acid, and to salt water can make 316 the preferred choice for use in processes that involve these solutions. The quality of the surface finish and the amount of cold work (most often referred to as the hardness, as in quarter-hard or half-hard) influences the corrosion resistance greatly.
- Grade 410 Stainless: This material is less common. This alloy possesses a very high hardness and great heat treatability. However, it also has poor corrosion resistance.
