Components of Pre-Engineered Metal Buildings

A pre-engineered metal building is made of many components.  The list below is a general breakdown of these components that make up a pre-engineered metal building.

Main Framing

The main framing of a metal building, also known as the trusses or purlins, is typically made out of steel.

Manufacturers can create custom shapes and sizes for this part of your structure to best suit your needs.

The structure and materials of the mainframe of a metal building can vary depending on your needs and specifications. Fabricators need to ensure that they are built to withstand wear and tear.

Structural Framing

The structural framing of a building, in general, is made out of steel.  Steel is a good choice for this component because it is strong and durable and can hold up to weather conditions.

The strength of steel comes from its chemical properties, which are controlled very closely during the manufacturing process.

A structural framing includes columns made to support the structure of the building, beams to support the loads from above, and purlins that hold the rafters in place.

Wall Panel

The wall panels are fabricated to have a strength of at least 125% of the building's design wind load. They are joined together with mechanical connections so they can be easily disassembled. The outside face is then covered in sheet metal or custom architectural finish, each chosen to provide the desired look for your building.

Roof Panels

Roof panels are designed to keep elements out of the building. There are different types of roof panels that can be utilized depending on weather conditions. They protect the building's interior from damage due to natural elements.

Roof panels are also designed for thermal properties, allowing the occupants to be protected against extreme heat or cold in harsh climates.

Liner Panels

The liner panels are the boards that make up the exterior of the pre-engineered metal building. These wall panels provide strength and insulation for your structure, keeping harsh weather elements out while keeping your items securely inside.

Liners are available in many styles to achieve individual styles, including wood or steel siding, vertical or horizontal ribbing, and brick or stone finishes.

Eave Struts

Eave struts are diagonal braces that provide added stability to the building. They are installed on each side of the building which provides additional support to metal walls, roofs, and floors against wind pressure.

This keeps the building standing tall, preventing damage that can be caused by strong winds.


Purlins are horizontal members that are placed at regular intervals between the structural steel beams of a building.

They create an evenly spaced grid of vertical columns, into which the floor decking is placed.

Purlins can be made from different materials- tubing or solid bar stock steels.

The size of purlins varies depending on the span of the building.

End blocks are located at both ends of purlins to provide a nailing surface for attaching roof decking and bracing.

Purlins can be either installed 24" on-center or 16" on-center, depending on the span of your building.


Mezzanines are a great way to utilize the space in your pre-engineered metal building. A mezzanine can be many things: an office, storage area, or even a separate apartment. When you need the additional height, the floor of your mezzanine will often include structural support beams which can withstand heavier loads. For further support, you can even place concrete piers on the floor to anchor the beams.

Experience a New Level of Quality, Affordability, and Style with Pre-Engineered Metal Buildings

Pre-Engineered metal buildings offer many advantages over conventional construction methods. They are stronger, more versatile, energy-efficient, and less expensive to maintain. Their durability is unmatched as their components are designed to stand up to harsh environmental conditions such as strong winds and heavy snow loads all year round in almost every region in the country. Pre-engineered metal buildings provide flexible design options that include a broad range of roof styles, sizes, and colors to choose from.

In addition, they are ideal solutions for just about any commercial or industrial application.

Frequently Asked Questions

How do I finance my project?

How long will my project take to complete?

Construction length can vary greatly depending upon your specific circumstances. We will talk through all of the project components and variables in order to establish a time frame and an overall game plan that works for everyone.

What potential location/site/land issues should I know about?

We suggest knowing the answers to the following questions in regards to a potential location for your next project:

Is there a clear title to the site?

Has proper zoning been approved?

Have surveys been taken?

Have watershed and drainage requirements been checked?

What building code restrictions govern the site?

Are there easements on the site?

Will they interfere with the use of the property?

Is the site big enough for future expansion and parking?

Will there be easy access to the building after the area develops?

What are the setback requirements of the lot?

What site preparation work is needed? (such as soil testing, clearing, grading, demolition, fill/dirt removal, etc.)

What traffic facilities are needed? (such as driveways, pedestrian walkways, traffic signs/signals, parking/handicapped parking, separate customer parking, etc.)

What will my project cost?

There is no way to accurately answer this question without considering many variables of a project. These variables include the use of the building, location, overall appearance of the exterior and interior, and compliance with all zoning, covenants, local codes, and regulations. We will meet with you in order to gather information about your needs and discuss all the details and variables that truly affect your specific project. Building costs can be provided after that initial meeting. We believe in being honest and upfront with you from the very beginning. We want you to have a clear understanding of the overall construction process and how we can best benefit you and meet your needs.
