Koski Ironworks Ltd. is an Ontario-based structural steel contractor specializing in fabrication, installation, and welding for residential and light commercial projects.
Founded in 2022, we work with general contractors, custom home builders, renovation contractors, and homeowners throughout Barrie, Muskoka, Collingwood the GTA, and surrounding areas.
Our approach is straightforward: provide quality workmanship, safe execution, and efficient service from fabrication through final installation.
Koski Ironworks Ltd. was founded by Logan Koski, a Red Seal Journeyman Ironworker with hands-on experience in the structural steel industry.
After entering the trade following high school and working his way to Red Seal certification, Logan founded Koski Ironworks with the goal of building a steel company known for quality workmanship, reliability, and doing the job right the first time.
That philosophy continues to guide every project we take on:
Built Once, Built Right.
Our company is built on three core values:
We take pride in delivering results that stand the test of time — structurally sound, clean, and done right the first time.
We work with general contractors, custom home builders, renovation contractors, and homeowners on residentia
l and light commercial construction.
Whether you need a single structural beam or fabrication and installation for a larger steel project, we bring the same attention to detail to every project.
When you work with Koski Ironworks Ltd, you’re choosing a company that values honesty, hard work, and quality craftsmanship.
We’re committed to building strong relationships with our clients and delivering steel work you can rely on.
