Dedicated Design Team For Your Custom Building Project

We’ve worked with architects and engineers to help deliver the custom plans that our customers want and our factory can fabricate and deliver.

With decades of combined experience, our team has the most comprehensive understanding of metal buildings around the globe.

One of SteelMaster’s stand out custom projects was a multi-million dollar Quonset hut home in East Hampton, New York known as the “Arc House.”

The nearly $4 million arch-style home was designed by world-renowned architect Maziar Behrooz of MB Architecture and Design.

The firm chose a metal Quonset hut because of its industrial look, cost-effectiveness and unobstructed interior space.

The Arc House wowed onlookers and gained respect in the architecture community with its modern design aesthetic for many years. It has been featured in many publications and has won several awards, including Pulse Magazine’s 2017 House of the Year, two AIA Peconic Honor Awards and an MCN Building and Roofing Awards.

Custom Products Direct From the Factory – No Middleman Markup

There are several parts and accessories you can purchase from SteelMaster to customize your building:

  • Endwalls: SteelMaster sells pre-planned commercial-grade steel endwalls that suit your needs. Our solid endwalls are pre-cut and die-punched for ease of assembly. All corrugated panels are cut exactly to fit.
  • Base connector: SteelMaster offers an option C-Channel or Industrial Base Connector to attach your building to its foundation. Arches bolt to the base connector, which anchors bolts to the concrete foundation. Using a base connector gives you the flexibility to move or expand your building and is great for existing slabs or block walls.
  • Skylights: Purchasing skylights allow natural sunlight to fill your building. Our skylights are specially designed to match the steel panels of your building. SteelMaster’s skylights disperse light three times better than conventional flat panel skylights. It is advised to install one skylight per 10 feet of building.
  • Window frames: Both popular sizes and custom sizes are available for side or end walls. Popular sizes include 24” X 36” and 48” X 36”, with both being 14 gauge.

We also have relationships with vendors that offer:

  • Insulation: Though our Galvalume Plus coating helps protect against the temperature better than any other coating in the market, you can insulate your steel building to keep heat/cold in or out. We offer batten or blanket insulation that is mineral fiber consisting of processed fiberglass.
  • Doors: We offer both garage doors and service doors. Along with standard sectional overhead garage doors, frames for bi-fold doors and rolling sheet canister doors are also available. Our service doors can be placed in either endwalls or sidewalls. We offer a 30” X 79” endwall door, 4’ X 7’ conventional endwall door and 66” X 79” double conventional endwall door.

Customize Your Building Before and After Purchase

You can add custom elements to your building after construction is completed should you choose, or repurpose your building in a number of ways.

If you need more space after your building has been assembled, you can add additional arches in 2’ increments to the structure after the initial construction of the building to give you additional square footage.

Since our endwalls are not load-bearing, you can also remove them to make the building open-ended, or customize the endwalls using materials of your choice. You can also install skylights in the arches by removing some of your existing building’s panels to add natural light to the structure.

Because of the building’s 100 percent usable space, you can redesign your building’s interior configuration if the use of the building changes over time. For example, the Oklahoma City Ballet purchased the American Energy Partners’ state-of-the-art fitness center in February 2017.

The fitness center had a basketball court, two racquetball courts, a rock climbing wall and two floors with weights and cardio machines.

The ballet company ended up converting the gym into administrative offices and a ballet school. The new facility has increased OKC Ballet’s available space from 8,000 square feet to more than 28,000 square feet.

We are very pleased with our Steelmaster building. This was my first time assembling one, and the quality of the... fitment is really impressive. I was skeptical of the added cost for the key way groove in the concrete slab, but now that it is completed I highly recommend it. We will definitely purchase another building from them in the more

This building was an good deal for the cost per square foot. Everything was included except the end walls, I chose to... build my own. I haven't built it yet due to weather but reviewing the assembly instructions it looks pretty straightforward and a helper or two and I should have it up in a weekend.Ashley and the rest of the staff were very friendly and professional. They even thought of something I didn't and called me with an add-on that was on sale. I hope to put up another in 3-5 years for another more

I received my building yesterday and I have to say THANK YOU VERY MUCH! Working through the process from ordering to... receiving the building has been above and beyond any expectations I had.

I was kept informed throughout the entire process and any questions I had were answered immediately. Many thumbs up to both STEELMASTER and Campbell Transportation!I highly recommend SteelMaster Buildings and their entire crewread more

Steel Master Buildings came through for us. We ordered a building (16x14) open ended and about half way through the... process, we ran into problems with conflicting data from our county regarding snow load. After our conversations with the company, they were able to make acceptable design changes that would get the building into compliance. SMB stuck with the process and got it done and that says a great deal about their customer service, I would certainly recommend them to anyone looking for this type of building.M.

We purchased a 10' x 20' building for storage and a covered place for our quad. The purchasing experience was easy and... informative. Customer service has been very helpful all throughout the purchase and build. I'm 60 and my son and I put it together by ourselves!! It was relatively easy and the result has exceeded our expectations. We'd highly recommend a SteelMaster building to anyone, great product! Lori C in Washington Stateread more

Everything started with great response time and answers to questions about the building. Any time I had a question I... could email the representative and I always received a timely and thorough response. I have not had a chance to put up the building yet so I cannot comment on difficulty or ease of building it. I was given a list of people in my area who I could and did contact about their process. I even went to see one person’s building and got a great walk through and recommendations for building mine when the time comes. The gentleman I contacted stated that putting up the building has it’s challenges but until I can get the money for the concrete pad and rental equipment I won’t know. My only complaint but this is from a very, very limited knowledge is that it seemed like the company was always trying to up sell something else each time they contacted me to see how things were going even after I told them I couldn’t afford to put up the building at this time. Otherwise, everything up to now has been very more

Great quality materials. We have had the structure up through the first winter, with snow and wind and it has done it's... job great with no issues. Make sure that you have a few people there to help with the construction, you could do it with two, but 4 is best for speed and simplicity. Overall great product and would recommend to more

Steel master not only had a large selection and wide variety of buildings their staff from sale to after sales was... fantastic. I had trouble with my local permitting office over the placement of the building, my after sales representative was very helpful in getting me a change in blueprints. Even now more than a year later they are contacting me, not to sell me anything but to ensure that I am enjoying my building. The building itself is extremely durable and strong, better than any stick build barn I could have more

Sales was very patient and helpful through the investigation and purchase process. The company was good to its word in... the promises and representations made by Sales. No gotchas! The after-sale followup was great - they seemed to anticipate what I would need to take delivery and actually erect the building. Delivery from the factory in Canada was flawless and painless. Customer service for erecting the building was a little spotty but I can't say it was anything they did wrong; mostly it was my impatience, particularly over the Thanksgiving and December holidays. I would have to say they are reliable and responsive and truly want customers to be satisfied with the entire experience. The product itself is excellent; everything fits exactly as it should, if directions are followed. I am very confident in the long-term durability of the more
