"Project was steel railing for front porch and walkway. Project was the custom to my needs and design preferences. I worked with Jimmy to get the kind of design we liked -- even walking 500 yards up the steet to show Jimmy an example of a design we liked. Project took longer than expected but during a COVID pandemic scheduling can be tough. The project was finished with truly professional and top quality workmanship."

"They quickly assessed the situation, gave a reasonable quote, and were very proficient and professional. My condo unit was under contract and a water leak caused by another unit needed to be repaired asap and they did it. Also kept me well informed."

"I had an outdoor metal handrail that was breaking off the concrete base. They contacted me quickly after Angi gave them my number and asked tons of questions to be able to give me a great estimate. The work they did was phenomenal. They not only reattached the handrail but strengthened the concrete base with metal beams to give the whole structure more support."

"I had to replace the railing on my front steps. They were very old and rusting through in places. I had another bid to replace it with wood that would have cost more than this steel powder coated railing. It is absolutely beautiful and has completely changed the curb appeal of my home. They are very polite and professional. Top notch work. You wonâ t regret hiring Pioneer Welding!"

FAQs for steel beams (structural) service projects in Seattle, WA

A steel beam weighs six to 12 pounds per linear foot, depending on its size and shape. That means a 10-foot beam rated at 10 pounds per foot tips the scales at 100 pounds. Commercial projects often use much larger members—some top 50 pounds per foot—so crews may need lifts or cranes to maneuver them safely into place.

On a new build, crews can slide a beam into an open frame in just a few hours. Replacing a beam inside a finished home takes longer—plan on two to three days—to shore up the structure, remove finishes, and work around plumbing or wiring. Your structural engineer will outline the steps, and you may want to stay elsewhere while the temporary supports are in place.

Yes—as long as a structural engineer signs off, swapping a load-bearing wall for a beam is a safe upgrade. A steel I-beam offers the best strength-to-size ratio and meets local codes with room to spare. Your engineer will calculate the load, specify the beam, and verify that the surrounding framing can handle the new setup.

Watch for rot, rust, cracks, or sagging—all red flags that a support beam needs attention. Water stains, uneven floors, or doors that stick can also point to trouble. If you notice any of these issues, call a structural engineer right away. Catching the problem early protects your home and can keep the repair bill from ballooning.
