"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."

"Ram Irons called me the same day I requested a Pro metalworker. He came the next day and measured and gave me a fair price for a steel handrail on my front porch. I agreed and he returned to his shop and fabricated, returned and installed it the same day. I was impressed by his skills, quality of work and friendly demeaner. I would reccommend them to anyone who needs wrought iron help."

"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

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.

While a high-speed circular saw will cut through metal, and even cut through multiple sheets at once, the fast-spinning saw blades create a lot of heat. This heat can damage paint and other protective coatings, leading to serious problems like rust over time. The cost to paint a metal roof again to avoid this damage is typically an additional $0.50 to $1 per square foot.

Welders use a variety of methods in their trade. Different types of welding are better suited for different purposes and contexts. For example, stick welding is a versatile form suitable for most metals and alloys. The most common types of welding include:

  • Stick welding: $100–$1,000

  • Metal Inert Gas (MIG) welding: $250 and up

  • Tungsten Inert Gas (TIG) welding: $250 and up

  • Gas welding: $150 and up

  • Forge welding: $15–$25 per hour

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.

The cost to weld aluminum averages about $14 to $22 per pound. The type of metal factors into the overall cost of any welding project due to the cost of the materials and the expertise required to work with it. Some of the most common metals used by welders include:

  • Magnesium alloy: $7–$16 per pound

  • Low-carbon steel: $11–$12 per pound

  • Stainless steel: $13–$15 per pound

  • Copper/brass: $24–$29 per pound

  • Cast iron: $38–$79 per pound

  • Titanium: $60–$85 per pound
