Structural steel can be defined as a construction material that is formed into various shapes and sizes depending on the manufacturers design. Structural steel is used everyday on large structures such as:

  • Lift Bridges
  • Swing Bridges
  • Suspension Bridges
  • Pedestrian Bridges
  • Highways
  • Overhead Sign Structures
  • Elevator frames
  • Elevated track framing

The below-mentioned protocols are limited to just a few of the inspection processes InTouch uses for structural steel inspections.

Visual Inspection

  • Anchor Bolts are inspected for defects and to ensure the threads are not damaged and adequate lubrication has been applied
  • Visual inspection are performed to ensure the structural steel displays all label markings and identifications.
  • Inspect to ensure the structural steel protective coating conforms to IBC 2006

Dimensions Inspection

  • A dimensional inspection is performed to confirm that the structural steel is manufactured according to the design drawing that specifies the dimensions and indicates the design tolerances.

Mechanical Inspection

  • Aterial test are performed to indicate the toughness of the structural steel.
  • Structural Steel Diameter measurements are taken with a micrometer to ensure dimensional accuracy.
  • Load bearing tests are performed to ensure the structural steel can hold the required load.
  • A tensile test is performed to test the tensile strength, the yield strength, and the elongation restrictions.
  • Corrosion tests are performed to verify resistance of the structural steel to corrosion

Acoustic Inspection

  • Ultrasonic testing is performed using sound wave emission and which calculates the amount of waves coming back which dictates if there are any defects or cracks in the welds.
