"Highly Recommend Optimiz3 – They Truly Optimize Your Ideas! After getting quotes from several teams for my fence project, I ultimately chose Optimiz3 – and I’m so glad I did. Jordan was incredibly easy to communicate with, and his professionalism stood out from other company. He not only took the time to understand my specific project needs, but he also helped me think through the bigger picture, offering valuable advice for future improvements. The team’s professionalism was evident throughout the entire 50-foot fence project. They arrived with top-notch tools and even took the time to help clean up my yard before starting, which was a thoughtful touch given how messy it was. They worked diligently, double-checked their work. All of my questions and concerns were addressed promptly and thoroughly. If you're looking for a company that goes the extra mile to ensure high-quality results, choose Optimiz3. They’ll optimize your project and exceed your expectations!"

I am a 6 year welder. I offer mobile welding and fabrication services. I regularly do gates and railings, trailer repair, and custom fabrication projects. I am very proud of the work I do. I am also a Marine Corps veteran

"QUALITY WORK. Kai and Team were on time, and stayed ahead of planned schedule. Most post holes get two bags concrete..on the important corner post he dug it very deep and put three. Always used levels and stringers. Never guessed. Measured again and again. Also had a custom gate built to on-site specifications. Really great work. Plus Kai and Team are adaptable and capable. Fencing, tree cutting, metal work, gates, and more. FIVE STARS ⭐️⭐️⭐️⭐️⭐️"

Welding questions, answered by experts

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.

Yes, an LVL beam is more affordable than the cost of a steel I-beam, totaling between $50 and $200 per linear foot as opposed to the $100 to $400 per linear foot you’d pay for a steel I-beam. Not only is the wood material more affordable than steel, but it’s also more similar to traditional wooden beams and doesn’t require as much retrofitting to connect joists.

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.

Some welding projects, such as repairing pipes or fences, require travel, whereas others, like furniture repair, do not necessarily require the welder to come to you. Travel and overhead factor into the overall cost of your welding project. Some of the most common welding projects include:

  • Metal furniture repair: $35–$100

  • Pipe repair: $200–$1,000

  • Small gates: $550–$750

  • Fencing: $1,200–$1,800

  • Fabricated sheet metal welding: $750–$2,500

Costs depend on metal type, fabrication complexity, labor, finishing, and shipping or installation requirements.
