"Simply wow! I had what I considered to be a relatively small project of adding a railing to our outdoor steps. Within minutes of my posting my request on Angie's List (through Allpros.com) I received a call from Jimmy. He was very helpful in my thinking through options for a stair rail. The next morning, Michelle came out to measure the stairs. Shortly after, I heard from Jimmy with an estimate that was much lower than I expected, and a time frame that was faster than expected. I got a few other estimates, but none came close to Jimmy's in cost or delivery time frame. I worked with Jimmy a bit more wanting to understand exactly what he was proposing. He was very responsive to my numerous inquiries, never treating me like a small potential customer. Jimmy came out to test the fit of the rail a few days after I accepted his estimate and the rail fit almost perfectly, thanks to Michelle's excellent work measuring and fabricating the rail. The railing took a few extra days at powder coat, but Jimmy has now installed it, and it looks great! I would not hesitate to recommend Steel works Northwest for your metal work needs and know who will be my first call if I have metal working needs in the future."

"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 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.
