  • Description
Our cutting edges and grader blades and designed and manufactured to meet industry standard for earthmoving machinery and equipment. Our products are widely used in many construction and mining equipment worldwide.

 We offer a wide selection of blades manufactured from several grades of high carbon and boron steel. Many of these products are made from both high carbon and boron steel that are heat-treated and hardened to improve the lifespan while meeting the demanding requirements of earthmoving and mining applications.

  Our production range can cover any products with maximum width of 410mm, maximum length of 6m and maximum thickness of 110mm.

 Adavantage of using Heat Treated Boron Material Ground Engaging Tools

 The above technical data shows that the Boron type of GET has superior mechanical properties with much higher resistance to wear and abrasion due to the nature of chemical composition. As a result,the lifespan of Boron type of GET will be at least twice that of carbon steel.Thus,the cost savings on downtime,labour charges and plow bolts and nuts are tremendous.
