Integrity and Safety Solutions for Complex Building and Infrastructure Components

Structural steel is vital in constructing durable and versatile buildings, transportation infrastructure and other complex structures. While steel can create long-lasting structures, it can have material defects that could cause safety risks. Steel components must also meet stringent regulatory guidelines.

Avoid potential dangers and costly construction issues with structural steel inspections and nondestructive testing services from TRC. We provide services during the production, shipment, construction and post-construction phases. At TRC, we know the applicable regulatory requirements and can work with you to ensure structural steel can withstand its expected application.

Protect Building Integrity With TRC’s Structural Steel and Nondestructive Testing Experts

TRC’s certified inspectors deliver cost-effective solutions throughout the United States, Europe, Asia, Mexico, South America and Canada.

Our materials engineers, nondestructive testing (NDT) technicians and steel fabrication shop inspectors provide assistance throughout all stages in a product’s life cycle from design to inspection, maintenance, repair and failure analysis. Our technical staff are certified and qualified to meet the requirements of ASNT Recommended Practice SNT-TC-1A and/or ANSI/ASNT CP-189/ISO 9712.

We support projects including:

  • Bridge fabrication and erection
  • Bridges
  • Buildings
  • Wind farm structures
  • Highway structures – signage and high-mast lighting
  • Pressure vessels and tanks (ASME, API)

We serve as an extension of your existing team, bringing our expertise to enhance projects, through modern and advanced equipment for reliable results that maintain safety and resilience. We identify issues quickly to avoid costly repairs, rework and wasted materials. Our thorough evaluations also enhance the life span of structures by identifying any imperfections that may cause issues.

Comprehensive Structural Steel and Nondestructive Testing Services

Our solutions ensure the longevity and safe function of steel structures. We have in-depth knowledge of all relevant codes stipulated by the American Welding Society (AWS), American Society of Mechanical Engineers (ASME), American Petroleum Institute, Steel Structures Painting Council (SSPC) and the American Society for Nondestructive Testing (ASNT).

Our services include:

Visual Inspections
Nondestructive Testing

Visual Inspections

Our visual inspections identify signs of damage like cracks, corrosion, spalling, deformation or misalignment. We look for these defects visually or use technology like drones, if necessary. These visual inspections cover all stages of fabrication and erection. We examine structural components, including beams, columns, connections and joints.

Nondestructive Testing

Through NDT for steel structures, we gain a more comprehensive view of structural steel without compromising its integrity. Our team is qualified to perform structural steel testing, including the following types:

  • Ultrasonic testing: This testing method involves sending ultrasonic waves through a steel structure to detect internal flaws and thickness.
  • Radiographic testing: X-rays or gamma rays pass through the metal to examine its internal structure for flaws or defects.
  • Magnetic particle testing: We run a magnetic current through the structural steel to discover cracks.
  • Liquid penetrant testing: This test uses a liquid dye applied over a non-porous surface like a steel weld to find imperfections.

Frequently Asked Questions

Learn more about structural steel inspections and nondestructive testing with the answers to a few common questions.

During the process of forming structural steel components, the metal goes through many changes, which can introduce imperfections like:

  • Porosity in the welding
  • Incomplete fusion
  • Spatter
  • Dimensional deviations
  • Rust, scratches or scaling
  • Material contamination
  • Deformation

TRC’s inspection and nondestructive testing services allow us to identify these defects to enhance safety, quality and regulatory compliance.

Structural steel fabrication inspections should happen frequently to cover every part of the process where defects could occur. After construction, inspections should occur about annually, especially after significant events that could impact the integrity. Our experts provide inspections before, during and after fabrication and offer ongoing support after construction.

The process for addressing structural steel defects may vary based on the issue. Sometimes, bonding or welding can fix cracks. In other cases, a component may need additional metal to strengthen it, or it may be better to restart the fabrication process. A new structural steel component may take extra time and funds but eliminates much costlier issues later, such as a structural failure.

The inspection process varies since new fabrication inspections focus more on ensuring materials and work meet specified standards. Inspections for existing structures focus more on assessing the current condition and whether the structure needs maintenance or upgrades. While both inspections use similar methods, they have different goals.

Detect Structural Defects Early With TRC

TRC embraces a spirit of collaboration, partnering our inspectors and materials engineers with our NDT technicians during critical and noncritical evaluations. We support developers, utilities, bridge and highway projects and other large projects with inspections and nondestructive testing for steel structures that reveal imperfections, improve safety and facilitate regulatory compliance.

We inspect structural steel throughout any project stage, from the initial fabrication to post construction monitoring. Contact us to learn more about our capabilities.
