Welding questions, answered by experts

The difference between a lintel and a beam is what loads each is responsible for supporting. A lintel is a type of beam that is responsible only for supporting the load above an opening, such as a window or door, and transfers the weight to the side walls around an opening. A beam supports the slab and transfers the load to nearby columns, which then disperse the load to the ground.

Some states require welders to be licensed and certified, while others don’t. However, it’s always a good idea to hire a licensed welder, regardless of requirements in your area, especially if you need welding for structural components of your home or gas lines. Licensed welders have gone through training and testing to prove their skills, so they’re less likely to make a mistake that could be detrimental to your home. Use Angi’s state licensing tool to determine whether your potential hire has a welding license.

Lally columns are named after their founder, John Lally, who owned a construction company in the 1800s. He invented the columns as a means of providing temporary support for beams and rafters in homes his company was renovating. The original Lally columns were also made of steel, although the inventory used a thicker gauge metal, which provided additional support for larger projects and long-term structural solutions.

Professional metal fabricators usually charge around $70 per hour. Three of the largest cost factors are the size and complexity of the project and the price of materials. The type of metal can impact the cost as much as the intricacy of the metal fabrication you want done. Another cost factor is your geographic location, as labor and materials can vary widely depending on the cost of living where you live.

Steel I-beams are an increasingly popular choice for supporting a structure because they support a large amount of weight with a small profile and without the need for load-bearing walls or supports underneath. This allows for more open floor plans, which most people tend to prefer. They also resist fire, pests, and rot and last for the lifetime of your home.
