About Company

Founded in 1976 by the Karnes family in Trinity, Texas, Trinity Steel Fabricators has grown to become an international player in the construction industry by fostering a culture of quality and customer service. Focusing solely on the industrial structural steel segment has allowed our staff to achieve expert status. With industry tenure comes a high degree of competence and an ability to optimize construction plans before steel even reaches the job site. Our certifications by the American Institute of Steel Contractors, and the City of Los Angeles are the result of rigorous adherence to quality standards and an intense pride in workmanship. Our steel can be found on several continents and in several industry segments. We participate in steel fabrication for petrochemical, mining, petroleum refining, power and other industrial environments, whether the requirements are major CAPEX infrastructure additions or small repairs and upgrades. We have shipped steel to West Africa and the Middle East. We have executed projects of significant size for Fluor, Foster Wheeler, Worley Parsons, Samsung, Jacobs, Mustang, Turner and RDS, just to name a few. We operate five fabrication facilities near Houston, Texas. With significant CNC tooling in place since 2008, these facilities are capable of producing as much as 2,500 tons per month of structural steel, making us the largest independent fabricator in the market we serve.

  • Delivery assurance in capital projects is critical. At Trinity, we deliver quality projects on-time and give you real-time status access through our TrinityLink customer portal.
  • With over 35 years of experience, Trinity has assembled the most knowledgeable staff to serve the most demanding projects in the industrial construction industry.
  • Quality driven business processes combined with on-site inspection teams delivers the highest quality fabricated structural and vessel steel to your project.


Trinity was started 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, Trinity Steel 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, Trinity will continue to grow and exceed customer expectations.
