About Us

Located in Leamington, Ontario, SEF® has been a leader in the North American metal fabrication industry since 1994. Initially specializing as a fabricator of commercial greenhouse parts, equipment, and structures, we now offer turnkey greenhouse solutions that seamlessly connect project development, manufacturing, installation, project management, and customer support.

Our team has also expanded outside the greenhouse industry to design, manufacture, and build pre-engineered steel structures within a variety of sectors. From churches to recreational facilities to office spaces, we offer our clients cost-effective and ergonomically engineered steel building solutions they can trust.

As a premier metal fabrication shop that provides complete solutions from design to installation, our expertise is guaranteed to help you meet your business objectives. We operate out of a 180,000 square foot production facility that is fully equipped with state-of-the-art machinery to manufacture greenhouse structures and a wide variety of steel buildings.

The SEF® team is committed to bringing your new project’s design, construction, and assembly vision to life.
