About Patriot Trinity, LLC

Since 1976, Patriot Trinity has grown into an international leader in the construction industry by cultivating a culture of quality and exceptional customer service. Our focus on the industrial and commercial steel segment has made our staff true experts — optimizing construction plans before steel ever reaches the job site.

We operate four fabrication facilities near Houston, Texas, equipped with significant CNC tooling since 2008 and capable of producing up to 1,500 tons of structural steel per month — making us one of the largest independent fabricators in our market. Our certifications from the American Institute of Steel Construction (AISC) and the City of Los Angeles reflect rigorous quality standards and intense pride in workmanship.

Our steel can be found on several continents — petrochemical, mining, petroleum refining, power, and other industrial environments — from major CAPEX infrastructure to small repairs and upgrades, including shipments to West Africa and the Middle East.

Like every company in the Patriot family, we live by five values that spell who we are — STEEL: Safety, Teamwork, Ethics, Enthusiasm, and Leadership — and one vision: Recognize a Need & Fulfill It.
