Structural Steel Quality Control Checklist

Inspect the delivery of steel upon its arrival at the site. This task is crucial as it ensures that the steel is delivered in the correct quantity and quality. Check the delivery against the packing list and make note of any discrepancies. Verify that the steel is properly packaged and protected from damage during transportation.

Review the certificates of compliance provided by the steel supplier. These certificates ensure that the steel meets the required standards and specifications. Verify the validity of the certificates and cross-check the information with the steel delivery.

Check the material identification markings on the steel to ensure that the correct grade and specifications are being used. Look for the grade marking, heat number, and any other relevant identification markings. Verify that the markings match the requirements specified in the project documentation.

Perform a visual inspection of the steel to identify any visible defects such as cracks, dents, or surface irregularities. Pay special attention to weld seams, corners, and edges. Use appropriate lighting and inspection tools to ensure accurate observations.

Verify the material grade of the steel to ensure that it meets the required specifications. Use non-destructive testing methods such as magnetic particle testing or ultrasonic testing to determine the material properties. Compare the test results with the specified grade requirements.

Perform dimensional checks on the steel components to ensure they meet the specified dimensions and tolerances. Use measuring tools such as calipers, micrometers, or laser measurement devices to accurately measure the dimensions. Record the measurements and compare them with the project specifications.
