With our in-house capacity and diverse industrial capabilities, we stand out among structural steel contractors, executing our fabrication process like few can. With years of industrial expertise, we offer you a comprehensive range of fabrication and manufacturing services, unrivaled in the industry.
As structural steel manufacturers, we are qualified with ASME U, S, and NBIC R stamps, performing your projects with nationally and globally accepted credibility and certifications. We are also licensed with the coveted API 4F Monogram, which certifies that we have passed rigorous auditing of processes and procedures that enable us to produce API Certified masts, derricks, and substructures. We manufacture, construct complete land-based drillings rigs, including drilling rig mast, derrick, sub structure, mud systems, water tanks, engine skids, jacking systems, wind walls and all interconnection piping spool systems.
We also specialize in heavy structural fabrication, including large ducting, panels, and stacks for SCR modules, heaters, reformers, and boilers. We fabricate platforms, ladders, and knocked-down steel for pipe racks, making us a reliable steel structure fabrication company for structures and buildings as well. Materials used include hot rolled steel, carbon steel, galvanized steel, stainless steel, Cor-ten®, aluminum, Inconel®, Monel® & Hastelloy® to name a few common alloys.
Shop Advantage and Capabilities
Knowledgeable shop operations teams, including in-house inspectors ensure unparalleled welding quality pertaining to many common and uncommon structural steel alloys. Products are inspected by full time quality control inspectors and procedures are assured by certified welding inspector (CWI). Our project managers work with each customer to streamline the fabrication of their products through our manufacturing facility.
The STI Group structural steel shops are equipped with the most modern state of the art welding equipment on the market, enabling us to provide very competitive pricing for our customers. Welding processes of GTAW commonly know as tig welding, GMAW-Short Arc and PULSE known as mig welding, SMAW referred to as shielded metal arc welding or stick rod, FCAW is known also as flux core welding, SAW is submerged arc welding, are all used in our facilities for broad application, diversity and fabrication efficiency.
And because we employ two shifts in our fabrication facilities, we can expedite and deliver your project efficiently helping to meet your deadlines. This includes tackling tough time sensitive shut-down work in which we excel in, when timing and deadlines are especially critical. While you have a project in our shop, it becomes your shop, with knowledgeable people, state-of-the-art equipment and facilities, and a friendly and cooperative attitude.
From project management through fabrication, welding, painting, assembly, testing and shipping, you get the services you need to produce your product. We want to become long-term partners.
