Pre-Engineered Metal Buildings (PEMB)

Pre-engineered metal buildings (PEMB) are one of the most efficient and reliable construction solutions for commercial and industrial projects. Designed and fabricated off-site, these structures arrive ready for assembly, reducing build time, minimizing material waste, and improving overall project efficiency.

At Craig Lee Construction, we deliver PEMB systems that are tailored to your project from the ground up. Whether you're developing a self-storage facility, agricultural structure, warehouse or commercial space, we focus on getting your building up quickly without compromising on durability or long-term performance.

Inquire about pemb builds

  • A PEMB is a structure engineered as a complete system and fabricated in a controlled environment before arriving on-site. Each component is designed to fit together precisely, allowing for faster assembly and consistent build quality.

  • Because major components are manufactured ahead of time, on-site construction moves significantly faster than traditional builds. This helps reduce delays and keeps your project on schedule.

  • PEMB structures are engineered to meet local building codes and are designed to handle environmental demands.

  • In addition to lower upfront costs, PEMB buildings often require less maintenance and can be designed with energy efficiency in mind, making them a strong long-term investment.

What to Know About PEMB Buildings

Pre-engineered metal buildings are designed for strength, scale, and long-term performance, making them a go-to solution for larger commercial and industrial projects. However, not every project requires that level of structural system.

Some builds are more straightforward, with smaller footprints and simpler requirements, where a lighter and more streamlined approach makes more sense.

Not Every Steel Building is the Same

One of those alternatives is ACT building systems.

ACT systems use cold-formed steel components that are bolted together on-site, creating a simpler structure that’s faster to assemble and well-suited for smaller or less complex builds.

What’s the Difference? ACT VS PEMB.

PRE ENGINEERED METAL BUILDING

Built for strength, scale, and long term performance

  • Designed as a complete engineered system

  • Ideal for large-span buildings without interior columns

  • Stronger structural capacity for demanding projects

  • Best suited for commercial, industrial, and self-storage developments

  • Built to support long-term growth and expansion

ACT BUILDING SYSTEMS

Built for simplicity, speed, and straightforward construction

  • Uses cold-formed steel components

  • Bolted together on-site with minimal complexity

  • Faster to assemble for smaller projects

  • Ideal for simpler structures and tighter budgets

  • Best suited for less demanding structural needs

Where These Structures Are Commonly Used.

Both PEMB and ACT structures are incredibly versatile.
The difference is less about what they can be used for, and more about how they’re designed to perform for your specific project.

You’ll find both used across a wide range of applications, including:

  • Self-storage facilities

  • Warehouses and distribution spaces

  • Commercial and retail buildings

  • Agricultural buildings and equipment storage

  • Workshops and shop spaces

  • Industrial and light manufacturing

  • RV, boat, and vehicle storage
