What Are Steel Structure Tests?

Steel structure testing involves verifying the mechanical, geometric, and structural conformity of steel structural elements, whether they are shop-fabricated or field-assembled. These tests cover all technical criteria necessary to ensure the structure's safe operation.

In this context, the following are performed:

• Material conformity checks

• Welded fabrication inspections

• Dimensional measurement checks

• Assembly alignment and tolerance checks

• Surface and coating inspections

• Non-destructive testing (NDT)

are carried out.

What is Manufacturing Inspection?

Manufacturing inspection involves verifying whether steel structural elements are fabricated in accordance with quality standards during the factory production stage.

During this process, the following are evaluated:

• Cutting and forming accuracy

• Weld seam quality

• Material certificates (EN 10204)

• Dimensional conformity

• Surface defects

• Heat treatment conformity

Manufacturing inspection ensures that defects are detected before they reach the site.

What is Assembly Inspection?

Assembly inspection covers the checks performed during the on-site assembly of steel structural elements. This stage ensures that the structure is erected in exact accordance with the project specifications.

During assembly inspection, the following are examined and verified:

• Bolted connection checks

• Welded field connections

• Verticality and horizontality checks

• Assembly tolerances

• Anchor and foundation connections

• Structural alignment checks

How Are Steel Structure Tests Performed?

Steel structure testing is carried out using systematic inspection methods during the fabrication and assembly stages.

The process generally proceeds as follows:

• Review of project plans and technical drawings

• Verification of material certificates

• Factory production inspections

• Weld quality checks

• Non-destructive testing (UT, RT, MT, PT)

• On-site assembly inspections

• Dimensional and alignment verification

• Final acceptance tests

Standards and Techniques Used

International standards form the basis for steel structure testing and inspection processes:

• EN 1090 (Steel and aluminium structures)

• EN ISO 3834 (Welding quality requirements)

• EN 10025 (Structural steels)

• EN ISO 5817 (Welding quality levels)

• EN ISO 9606 (Welder qualification)

• EN ISO 15614 (Welding procedure approval)

What are the application areas?

Manufacturing and erection inspection is carried out in the following areas:

• Steel structure buildings

• Industrial facilities

• Bridges and viaducts

• Power plants

• Warehouse and hangar structures

• Steel platforms

• Heavy industrial facilities

Advantages of Steel Structure Tests

• Enhances structural safety

• Detects manufacturing errors early

• Ensures assembly accuracy

• Guarantees project compliance

• Ensures adherence to standards

• Delivers long-lasting structural performance

Disadvantages of Steel Structure Tests

• Detailed inspection processes can be time-consuming

• Requires operational planning for fieldwork

• Can create a documentation burden

• Necessitates specialized personnel
