Qualitest introduces the QualiBend II to improve the stability of infrastructure

When developing infrastructure for extreme climates, the manufacturing and construction industries need the most dependable building m aterials. To examine the durability of these materials at low temperatures, the QualiBend II is specifically designed to test the performance of reinforced rolling steel bars, steel building reinforcements, and steel pipes under severe conditions.

With an easy-to-use control panel and a modular design that can test a range of different sample sizes, the QualiBend II consists of a hydraulic power pack with a cylindrical mandrel mounted vertically within a strong steel frame, which also carries two fixed reaction rollers. These rollers are fitted on the beam and can be easily adjusted for distances from 5mm to 50mm.

During these tests, steel samples must withstand being bent around a pin in a cold environment without cracking. Samples that can endure testing by the QualiBend II will meet the requirements of international specifications such as ASTM A615 A615M, ISO 7438, and GB 232, guaranteeing the strength of these materials to support infrastructure in even the toughest conditions.
