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 building
questions, answered.

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

Pricing depends on size, features, and site conditions. We provide accurate quotes after an initial conversation and on-site visit. Contact us for a personalized budget.
From the first call to final installation, the entire process typically takes two weeks or less, depending on complexity, manufacturing, and installation schedules. The on-site visit and design phase usually wrap up within a few days of the first call, and the actual installation is typically completed in a matter of days depending on the building size and complexity.
It depends on your location and project size. We recommend checking with your local building department. We can provide certified engineering plans if required.
We build to your exact dimensions, there are no preset sizes. Clear spans up to 40 feet are common, and we can adjust orientation for larger widths when needed.
Our premium baked enamel sheet metal roofing is designed to reflect significantly more solar heat than standard roofing materials. This helps keep the interior noticeably cooler, especially in the hot Southern California and Arizona climate. Additional ventilation options are also available for even greater temperature control.
We keep it simple and transparent. We take a 10% deposit once you approve the design and want to move forward. For larger projects over $10,000, we collect a 45% material payment on the day we arrive to build with 100% of the materials on site. The final 45% balance is due upon completion.
