Construction and steel structures
Structural steel and construction products from Turkish fabricators inspected for execution class, welding, geometry and corrosion protection.
01Built to the execution class
Construction projects source structural steel, façade components, bridges, platforms and building products from Turkish manufacturers. Requirements are defined by design codes and execution standards such as EN 1090.
QUALITAS TR inspects fabrication against the execution class, verifies welding, dimensions and corrosion protection, and supervises loading.
02Typical quality risks we see
- Execution class requirements not applied
- Welding and NDT gaps
- Hole and dimensional deviations causing site fit problems
- Inadequate coating or galvanizing
- Missing traceability
03How QUALITAS TR supports construction and steel structures buyers
