MATERIALS SELECTION

As the strategic partner of Shandong Iron & Steel Group , Higher Blades owns a huge advantage of raw materials.Shandong Iron & Steel Group , Jinan Steel developed a Brinell hardness wear-resistant steel 360-500HB, specifications covering thickness 10-50mm, and the drafting promulgated a national standard, GB / T24186-2009 "high strength wear-resistant steel construction machinery." . Our products have been certified by globally qualified independent laboratory testing Jigang, more protection of the quality and stability of the product.With deep experience in steel industry, we can select wide range materials to make it suitable for its application and bring best mechanical properties. Cooperated with Shandong Iron & Steel Group, we can provide you both standard and newly developed materials or even design a new material to meet customer's requirement.
