Trinity Steel Fabricators was founded by Roy Karnes Sr., a retired steel executive of International Steel, in 1976. He launched his second career near his favorite weekend escape near Lake Livingston in Trinity, Texas just north of Houston. Later, Roy’s two sons, Roy Jr. and Randy, joined the business making the company a family endeavor.

Before coming to Trinity Steel, Roy Jr. spent 25 years at IBM and brought his experience of computer systems knowledge from Fortune 500 companies to Trinity Steel. Under Roy Jr.’s guidance, the Trinity Steel team modernized information infrastructure systems to the production control, shipping, estimating, project tracking, document control and customer support functions.

With these changes, Trinity Steel was set on a path with quality measures fully supported by business systems and full CNC tool integration managed by a materials and production optimization system. Today, tightly integrated information systems and business processes set us apart from our competition and make us the preferred supplier in our industry.


Although the Karnes family departed from the business in 2010, Patriot Trinity continues to hold the values and quality systems that made it great through the continuing efforts of its highly skilled and experienced leadership team. With such internal projects as renewal of safety protocols in 2011, shop floor optimization construction in 2012, and facility expansion in 2013 and 2022, Patriot Trinity will continue to grow and exceed customer expectations.

In 2019, Trinity Steel Fabricators was sold to Patriot Erectors, LLC who operates a Texas-based steel fabrication and erection company founded in 1991. Patriot Erectors is a leading steel erection company that also offers value added specialty and miscellaneous steel fabrication services, creating a seamless turnkey experience for its clients. The acquisition of Trinity Steel Fabricators will provide Patriot Erectors immediate growth in the industrial and commercial markets. Both companies are certified by the American Institute of Steel Construction (“AISC”) and will provide the highest quality fabricated structural steel in the marketplace. Trinity Steel Fabricators has transitioned into Patriot Trinity, LLC.

Let Get Started


The AISC’s certification programs are the most widely recognized standard for the structural steel industry. Their goal is to help companies build quality structures, focusing on error prevention at the beginning of the project, rather than error correction if something goes wrong. Patriot Trinity’s fabrication certification was first awarded in 1997 and erection certification followed in 2009.
