WHAT CUSTOMERS SAY

What Our Customers Say.

The owner provided everything I asked for and was a wealth of knowledge, guiding us to what would work for our situation. The guys who came out were professional and represented the company well. I couldn't recommend them higher - I'm already trying to book another project.

They installed an RV garage for us and did an excellent job. Later they raised it for a roll-up door and added a utility garage - beautifully done, highest quality. A job is only as good as the company that stands behind it, and Steel Strux stands behind their product 100%.

Great service. It's been 4 years since Steel Strux installed my building and I couldn't be happier. From the sales guy to the installers!

I used Steel Strux at my house several years ago, so I decided to use them again at a rental house. Very happy with their product and especially the crew that does the assembly. An excellent product, a good price, and a warranty. Would I use them again? Yes, absolutely.

Our experience was stellar from the start. Nick came out and measured our trailer, and I told him what we wanted. The install crew was awesome - the quality and workmanship is exactly what we were looking for. Thank you for a job well done!

I was very pleased with the whole staff. Nick was more than helpful and made sure every detail was addressed in the installation of my carport. I highly recommend Steel Strux to anyone looking for a carport or RV cover. Great work!

FAQ

Steel garage questions, real answers.

Don't see your question? Call us at (888) 820-4992 or schedule a free visit and we'll walk through it together.

Steel garage pricing depends on dimensions, features (doors, windows, insulation), and site conditions. A basic 1-car garage starts in the low thousands, while a large 3-car with workshop can range significantly higher. The best way to get an accurate number is to schedule a free on-site visit. We'll measure your property and provide a firm, all-inclusive quote with no hidden fees.
We build to any custom dimension. Common configurations include 1-car (12' x 20'), 2-car (24' x 24'), and 3-car+ (36' x 24' and larger). But because every garage is custom-engineered, we can adjust width, depth, height, and door placement to match your exact property and vehicle requirements.
Absolutely. Our garage-plus-workshop combo is one of our most popular configurations. We can partition the interior into separate vehicle and workspace zones, each with its own walk-door access. Insulation, ventilation, and electrical rough-in packages are available to make the workshop comfortable for year-round use.
In most California cities and counties, yes. A building permit is required for a detached steel garage. We handle the engineering side: stamped structural drawings, foundation plans, and all documentation needed for your local building department. We'll review the specific requirements for your area during the on-site visit.
Most standard steel garage installations are completed in a single day by our professional crew. Larger or more complex builds (multi-bay with workshop, loft configurations) may take 2 to 3 days. The full project timeline from initial visit to completed installation typically runs two weeks or less, depending on permitting and manufacturing schedule.
Yes. We offer flexible financing options including monthly payment plans from 24 to 72 months, same-as-cash terms (3, 6, or 12 months), and financing up to $50K on the building price. We can walk through your options during the on-site visit or over the phone beforehand.
