PEMB: Pre-Engineered Metal Building

Posted on: April 27th, 2016 by Jazzy Elliott 1 Comment

A pre-engineered building is the perfect choice for a wide range of structural and aesthetic design choices.

Pre-engineered Metal Buildings are typically known as buildings that are all metal but that isn’t always the case. The major difference between the metal building and the other systems is the way the system is designed and the nature of the components. The design of the PEMB is processed through complex software that analyzes each of the various members at all locations along the lengths of those members.


Historically, the primary framing structure of a pre-engineered building is an assembly of I-shaped members. A computer is used to design the beams for these building. They are designed to meet the required maximum load at each point along the length of the beam. This is why you see tapered beams and columns in a metal building. This is one of the reasons that metal buildings are less expensive than other types of buildings. The I beams are then assembled to form the entire frame of the pre-engineered building. Once the frame is in place our teams will use a variety of materials (dependent on each project) to create the outer walls, roofing, and interiors. Some of these materials include:

Advances in computer-aided design technology, materials, and manufacturing have helped grow the amount of styles available when you are designing and customizing a PEMB to your exact needs


When designing a pre-engineered building, engineers consider the clear span between bearing points, bay spacing, roof slope, live loads, dead loads, collateral loads, wind uplift, deflection criteria, internal crane system, maximum practical size, and weight of fabricated members. Once all of these factors have been determined and input, the designers will then select the most efficient I beams size for their projects based on the computer’s recommendations.

Energy Efficiency

Because buildings account for such a significant amount of the energy consumed in the world, choosing materials and designs with sustainability benefits provides one of the biggest opportunities to be environmentally conscious. There are a wide variety of insulation systems that significantly improve the performance of the roof insulation. Also, an efficiently designed pre-engineered building can be lighter than conventional steel buildings by up to 30%. Lighter weight means less steel, and a potential price savings.
