Metal Buildings are a highly specialized field. Many people make the mistake of assuming all contractors or suppliers are the same. JB STEEL® prides itself on designing & delivering the highest quality metal buildings. Our partnership with Metallic Building Company & NCI Group began in 1997 & has continued to flourish. During that time we have received numerous Metallic awards for excellence & merit, culminating in 2015 when we were awarded Metallic Builder of the Year.

Customer Testimonials
"JB STEEL® designed and built our new facility in Medford, Oregon seamlessly and met our timeline. They were great to work with every step of the way; from guiding us through frustrating permitting issues to implementing our requested mid-project design changes and finally keeping up with consistent communication to ensure we were updated on the progress of the job. All of their team members were the upmost professionals to work with and always provided needed information to us that ensured an on-time project completion. We appreciate their hard work and definitely look forward to working with them again!"
"JB STEEL® recently designed and constructed a beautiful new building for our property and were an absolute pleasure to work with. They understood our unique vision and executed it perfectly, met our standards of quality, and did it on all a very tight timeline."
"We make a lot of changes and we need them to be on our team, not opposing each other but walk through it together to figure out a solution. We put them through the wringer and they delivered. We re-engineered two or three times; it was a long ways from home, and they made it happen on several levels."
Types of Metal Buildings We Build
Learn more about the different types of steel building construction and what purposes they serve
Metal buildings aren’t one-size-fits-all. At JB STEEL®, we engineer and erect a variety of steel building systems—each designed to meet the unique needs of industrial, commercial, aviation, and warehouse projects across the Western U.S.
Clear Span Structures
Clear span metal buildings eliminate interior columns, creating wide-open floor space ideal for warehouses, aircraft hangars, and manufacturing plants. With spans reaching well beyond 200 ft, these structures maximize flexibility for storage, machinery, or aviation operations.
Multi-Span / Modular Frame Buildings
For very large footprints, multi-span buildings use strategically placed interior supports to balance economy and strength. This design is common in distribution centers and large-scale production facilities where square footage matters most.
Hybrid Tilt-Up & Steel Systems
Many clients benefit from combining concrete tilt-up wall panels with steel roof framing. This hybrid approach delivers speed, durability, and impressive clear spans while keeping energy performance and fire ratings in check.
Custom PEMB (Pre-Engineered Metal Buildings)
Pre-Engineered Metal Buildings allow for rapid delivery and cost-efficient construction. With our in-house DESIGN-ASSIST™ process, we tailor PEMBs to your load requirements, insulation needs, and architectural vision.

Commercial and Industrial Metal Building Construction

We have a proven track record of delivering high-quality results, on time and on budget. We understand that every project is unique, and we work closely with our clients to ensure that their specific needs are met.
Industrial
When it comes to choosing an industrial metal building contractor, there are many important factors to consider. However, JB STEEL® is the clear choice for high-quality industrial metal building construction services. We have a team of experienced professionals who have built many different shapes and sizes of industrial metal buildings and love a challenge.
Pre-Engineered Metal Buildings
When it comes to construction, pre-engineering can be a lifesaver. By pre-engineering metal buildings to exact design specifications, we can ensure that the construction process goes smoothly. By carefully planning and designing the building in advance, we can avoid potential problems and ensure that the final product meets all of the necessary requirements.
COMMON BUILDING SIZES
JB STEEL® specializes in commercial and industrial high quality 10,000+ Sq Ft buildings.
Below are some of the most common commercial and industrial building sizes. JB STEEL® can build these or any custom building size.
Why Pre-Construction Is Important In The Metal Building Process
Pre-construction is a vital, yet often overlooked, stage of the commercial and industrial metal building process. It requires careful consideration of various factors including site analyses, architectural drawings and specifications, permitting requirements, material selection, structural reviews and cost assessments. Pre-construction ensures the successful completion of an entire project on budget and on time by coordinating the many components required to construct a building in a reliable manner without surprise expenses or delays. Neglecting pre-construction can lead to significant setbacks down the line and ultimately cost more time and money than if pre-construction had been considered from the start. Therefore, it is important that all stages of planning be given due respect when taking on any sort of large construction project.
Education is Key
Part of our mission is to educate customers so they can make the best decisions. This is one area where we set ourselves apart from other companies. It is our goal to ensure you are getting exactly what you need. Too often a customer makes a decision on a price alone, but is not aware of what they have just purchased. The metal building market is flooded with “cheap” options guaranteeing the “lowest prices online”. This fast buy now mentality misleads customers into believing they are making a prudent cost-efficient choice. Remember that the material cost is only a small portion of any project. Purchasing a building before you have a complete plan for permits, foundation, and installation can be costly in many different ways. A little education goes a long way. A lot of education leads to real success.
