"Vincent had an opening and started the job right away. The job presented some problems because the gate was made of thin inch and one half metal tubing that was difficult to weld. Vincent’s practical abilities with the welding and some inventive engineering not only got the job done but did it in a timely manner. I would highly recommend TM Steel for any project they would be willing to do."

Welding questions, answered by experts

Welding is the process of using extreme heat—and, sometimes, pressure—to attach two pieces of metal. In contrast, metal fabrication is a more involved process that can include welding, sheet metal work, bending, and other forms of metal manipulation. Metal fabrication is a large-scale project that may or may not involve welding, while welding is more often a step in larger fabrication projects.

Cutting rectangular ductwork requires careful measurements and the right technique. Use a measuring tape and pencil to mark the cutting lines accurately. Tin snips are excellent for straight cuts on smaller ducts. For more extensive or thicker rectangular ducts, a reciprocating saw with a metal-cutting blade is effective. 

Ensure the duct is well-supported and secure while cutting to prevent wobbling and maintain precision. After cutting, use a metal file to smooth any sharp edges, ensuring safety during installation. 

Costs depend on unit complexity, labor, wall mounting needs, and additional accessories like floating shelves.

Since water heaters are primarily made of metal, they’re commonly accepted by scrap yards and collectors. Don’t expect to fetch a high price, though—water heaters are mostly steel and aluminum, which aren’t high-value metals. Some components are made of more valuable metals, like brass and copper, but they’re a small portion of the heater and won’t affect the price much.

To maintain custom or fabricated metal structures and extend their lifespan and appearance, perform regular cleaning, apply rust prevention treatments, and use protective coatings.
