MECHANICAL AND CHEMICAL TESTS APPLIED TO TUBES & PROFILES
Mechanical Test: Tensile test is applied to a sample from the raw material or the final product to examine conformity with accepted standards and customer requests.
Chemical Test: Not only before accepting the raw material, but also during production process, chemical tests are applied to samples to examine conformity with accepted standards.
Hardness Test: With this test, surface hardness of the raw material or the final product is measured.
Expanding test: Several samples are collected during production process and are expanded using special techniques to control whether there are cracks or openings through the seam.
Flattening Test: Several samples are collected during production process and are flattened using special techniques to control whether there are cracks or openings through the seam.
Bending Test: Several samples are collected during production process and are bended by 900 to observe the durability of the seam in shaping the final product.

MECHANICAL AND CHEMICAL TESTS APPLIED TO SPRINGS & WIRE
Raw Material Chemical Tests
Raw material is meticulously selected after wire rod mill test reports are carefully examined. After this selection process, several chemical tests are applied to wire rod to understand if the product matches with mill test reports and our requirements.
Raw Material Mechanical Tests
Tensile strength tests are applied to all wire rod to understand if the product matches with mill test reports and our requirements before they are placed in the raw material stock area.
Spring Wire Tests
• Tensile strength
• Torsion
• Diameter control
• Dressage
• Wire surface control
• Wire knot test
• Wire bending
Above test and controls are applied to measure conformity with ts 2500-1 en 10270-1.
Moreover, fatigue-strength test is applied to springs and spring systems to examine conformity with tse 7167 spring mattress standard.
