HOW IT WORKS

The Steel Strux Difference:
Our Four-Step Process

Most steel companies sell from a catalog over the phone. We come to your property, design around it, and give you a firm price before you pay anything.

STEP ONE

On-Site Visit

We measure your property and review options in person.

STEP TWO

Custom Design

We engineer your structure for your exact dimensions.

STEP THREE

Manufacturing

We manufacture your steel structure using the highest quality materials to match your custom specifications.

STEP FOUR

Professional Install

Our experienced crew installs your structure with precision and attention to every detail.

WHY STEEL STRUX

There's a reason we're
different from the catalog companies.

Most companies push you toward a size they already make. We start with what you actually need, and engineer from there.

Most Steel Companies

Catalog-first.
  • Preset sizes only. You have to adapt your project to fit their standard sizes.
  • Phone-only sales. No one ever sees your site.
  • "We'll figure it out at install." Surprises after commitment.
  • Generic sales reps with no real engineering input.
  • Color and option choices made from a tiny online thumbnail.

Steel Strux

Site-first.
  • Any dimensions. We engineer the building around your space.
  • Free on-site visit with field measurements before you pay.
  • One clear quote. You see the real site, the real plan and real price upfront.
  • Direct line to a real builder from first call to final install.
  • Real color samples reviewed in your driveway, in actual sunlight.

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

Common 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.

It's free because we believe a building this important shouldn't be sold over the phone from a catalog. We start with a quick phone conversation to understand your needs, discuss options, and explain which services and products may best fit your project. We then provide a no-obligation on-site visit with no deposit and no pressure to buy.
Yes. Our structures are custom-engineered to your width, length, and height, not pulled from a catalog of preset sizes. There are certain structural maximums, but within those limits the dimensions are yours to define.
From the first call to final installation, the entire process typically takes just a few weeks, 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 is always best to check with your local municipality or building department to determine if a permit is required for your project. Certified engineering plans and stamped drawings are available upon request if needed.
We offer a full color palette for roof, walls, and trim. All sheet metal is finished with durable baked-on enamel that is guaranteed not to rust or fade. We also bring real, physical color samples to your on-site visit so you can see them in your actual lighting, against your house and surroundings. No more guessing from a tiny website thumbnail.
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.
