"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 welder and metal fabricator with more than 10 years of experience. I have a wide variety of skills including, but not limited to; metal handrails, stairway railings, high end stainless kitchen accessories, custom range hoods, sanitary stainless, repair or modification of metal features, and structural steel. In every project or job, one must consider three main factors that will dictate the outcome: how much will cost? How long will it take? How well will it be done. I prefer to focus on the latter. I will get it done right, and a will get it done fast.

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

Choosing the right metal fabricator for your project begins with research. Find a reputable fabrication company by searching for reputable contractors in your area, and then reviewing photos of their previous work, customer reviews, and photos of the company’s workshop.

Once you’ve narrowed down the list, contact the companies to ask about the types of metal fabrication projects they specialize and inquire about guarantees and warranties on workmanship. You should also ensure the company uses high-quality material, and ask about the schedule and turnaround time for your proposed project.

Most projects take 1-4 weeks, depending on material sourcing, design intricacy, and required finishing treatments like powder coating or galvanization.

Custom metalwork offers durability, design flexibility, and unique aesthetics tailored to specific needs.

A steel beam is stronger than a wood beam and requires fewer vertical supports underneath, which means it’s a better option for larger structures or if you want an open space under your home that doesn’t have posts as obstructions. However, steel I-beams cost more than wood ones, and they can be difficult to install retroactively, as getting them into the basement area can be challenging, if not impossible.
