Compare the Top Rated Steel Building Brands - Best & Most Popular Steel Building Manufacturers

Although steel buildings have been a popular construction choice since the debut of the Quonset hut during World War II, they were mostly relegated to industrial industries. But, new technologies and innovations broadened the appeal of this cheaper, faster alternative.

In this guide, we discuss the best and most popular steel building manufacturers of 2019. We also describe what to look for in a steel building, potential add-ons, and how to choose the right company for your construction project.

Benefits of Owning a Steel Building

Price and speed are the main advantages of a steel building, and both are thanks to the prefabricated nature of the components. Typical construction projects take six months or more to complete but steel builds average less than half that time, leading to significant savings on labor costs.

Another benefit is the material itself, which saves money on insurance since it's less expensive than wood and concrete (and offers greater fire resistance). It also is a more environmentally friendly choice with an 88 percent recycling rate.

Steel buildings also last for decades without the maintenance required by conventional construction materials. They're noncombustible; they don't leak, shrink, or swell due to climate changes such as humidity; and they resist pests like termites.

Choosing the Right Steel Building Company

When choosing between vendors, you want to consider the following:

  • The types of buildings they specialize in
  • The range of services they offer
  • The building materials they use
  • Whether they offer engineering services
  • The level of customer service provided
  • Whether the company is certified

Types of buildings

There is an enormous variety of steel building types available, but most companies choose to specialize. They may focus on a particular size or instead categorize by functionality. Sizes range from 10' x 20' to 150' x 300'. Common functions include factories, garages, warehouses, and agricultural buildings. But, these have expanded to include retail and office space and even residential buildings.

Finally, you also find companies that house their own design staff, allowing you to customize construction of your steel building.

Services offered

Not all steel building companies offer the same types of services. Some simply manufacture the building components and sell them as kits. Then, you as the client either assemble the building yourself or hire a contractor. They may also connect you with a contractor who has the necessary certification to complete construction (check whether the manufacturer or contractor provides the warranty).

Some steel building manufacturers also offer building rentals if your need is only short-term.

Steel building materials

The main materials used for the building's exterior include:

  • Galvanized or Galvalume steel with an alloy coating that extends the material's life in a corrosive environment, such as the salt air of coastal areas.
  • Heavy gauge steel panels should include a sealing finish process, weather-resistant paint, and corrugation for strength.
  • Steel labeled as "recycled content" usually includes up to 80 percent recycled materials.

Engineering services

Manufacturers also vary according to the types of engineering services they offer, with some staffing in-house design teams and others outsourcing this role. Others specialize in specific types of buildings, such as those used for barns and storage, and don't offer customization. Finally, some vendors offer fully customized, design-build services.

Customer support

Ideally, your chosen steel building manufacturer offers support throughout the process, from design and purchase through construction and even after you take possession to address and resolve any issues you experience. Before signing anything, clarify the company's methods for supporting its customers and how easy (or difficult) reaching them will be.

Ideally, the company offers a combination of online, phone, and live support, including representatives to assist during the design and construction phases.

Manufacturer certification

The intention of certification is ensure potential clients that the manufacturer provides quality products. Look for the following:

  • American Institute of Steel Construction (AISC): This trade association's guidelines evaluate each step of the construction process
  • LEED: This certification indicates environmentally-friendly products
  • Metal Building Manufacturers Association (MBMA): Partners with IAS to inspect steel buildings for quality

Steel Building Add-Ons

The pricing you see for steel buildings generally covers only the basic structure. Add-ons are those features that turn a large metal box into a building. The most common add-on is insulation. Today's building codes often require insulation, even for storage facilities. Insulation adds to your initial cost but saves money in the long run on energy bills. If you also add a vapor barrier to your roof and walls, you help protect your building from condensation.

Utilitarian add-ons include:

  • Pedestrian doors
  • Vehicle doors
  • Windows and skylights
  • Gutters and downspouts
  • Roof-mounted solar panels (check weight requirements)

Of course, you can also choose add-ons designed to improve the building's aesthetics. Typically, this means exterior choices such as building color and finishing options such as brick, stucco, or wood.

Adding partitions or interior walls is usually done by the contractor you hire to erect the building, not by the manufacturer.

Additional Considerations when Purchasing a Steel Building

In addition to considering the specs of the building itself and how they meet your needs, it's helpful to understand maintenance needs and the building codes and regulations in your area.

Maintaining your steel building

Regular preventive maintenance protects your investment and helps guarantee the safety of employees, clients, and customers. At a minimum, perform routine checks every six months. Ideally, your dealer agreement includes these bi-annual inspections. Make notes of issues that need attention. If you notice repairs or renovations are needed, schedule a building inspection right away. Keep detailed records of all inspections and repairs.

It's also a good idea to inspect your steel building after a heavy storm, such as hail or heavy rain or snowfall. Gutters and downspouts are valuable add-ons to protect your building against precipitation.

Building codes and permits

Even though erecting a steel building differs from conventional construction in myriad ways, you still have to meet building codes and other regulatory requirements. Check your local government website to determine zoning, fire safety regulations, and more.

In addition, you need to file a building permit, which requires submitting a certified blueprint and any other required information. This may include:

  • The building's dimensions
  • The building's purpose or function
  • The building's location
  • The foundation's details
  • Building schedules
  • A letter of structural assurance

Again, your local government website should include permitting requirements. Your dealer representative should be well-versed in local building codes and permitting.
