"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."

"Ariel transformed our home with his beautiful iron railing. We had old wooden balusters that did not fit the style of our home. After first meeting with Ariel and going over the look I was hoping for, he made a sample to give me an idea of what the new railing would look like. The quality of his sample was amazing and he listened to exactly what I wanted. The railing came out even better than expected!"

Welding questions, answered by experts

Cutting round ductwork requires precision and the right tools. A duct cutter, specifically designed for circular ducts, is ideal. First, mark the cutting line on the duct using a measuring tape and pencil. Then, position the duct cutter's blade on the marked line. Apply steady pressure, rotating the cutter around the duct. The sharp blade creates a clean, precise cut. Alternatively, a reciprocating saw with a metal-cutting blade can be used for larger round ducts. Ensure the duct is securely held in place while making the cut to prevent slips and maintain accuracy.

You should not do your own welding unless you have the proper training and experience. Most home electrical systems can only handle MIG welding, which creates weaker bonds than TIG welding and won’t work on certain metals or metal thicknesses. Both welding forms usually require the use of shielding gas, which can be dangerous to store at home. Additionally, welding machines create temperatures of over 3,000 degrees, and the sparks can blind you if you don’t have the proper equipment. As such, it’s usually better to hire a professional welder for your welding projects.

Yes, but you’ll need reliable steel-cutting tools and safety gear to get started. Shipping containers are typically around ¾ inch thick, so it’s entirely possible to cut through them, but experience and the right equipment are very important. When possible, try to get a container as close to the size you want it as possible.

This all depends on the tools you have on hand and whether you’re trying to cut a straight line or shapes. 

The best tool to use for straight lines is either a circular saw or table saw. When cutting shapes, a jigsaw will be the easiest and most precise tool to use. 

Yes, you can cut plexiglass by hand using a sharp knife or blade (utility knife, box cutter, glass cutter, etc.).
