We provide a diverse range of blades and lateral cutting tools crafted from various grades of high-carbon and boron-alloy steel. Numerous items in our collection utilize a blend of high-carbon and boron-alloy steel that undergoes heat treatment and hardening processes to enhance durability and fulfill the rigorous demands of excavation and mining operations.
The grader blade and lateral cutting tools serve as primary and auxiliary grading equipment, respectively, working in tandem to perform soil cutting, scraping, transporting, leveling, shaping, and maintenance tasks on gravel roads, roadbeds, topsoil or turf removal, excavation, slope scraping, and grading. These tools also contribute to preventing potential damage.
* Through professional quench-tempering processes to guarantee excellent mechanical properties, high strength and superior wear resistance to bending and breakage.
* Hardness 280-320HB for reduced wear and longer life, adding value to your products further to your business by maximizing the durability of your products.
* Optional material with high carbon steel or heat-treated boron steel for different appliions.
* Available dimensions for all standard grader blades or customized dimensions,such as 5 feet/6 feet/7 feet/8 feet/11 hole/ 13 hole/15 hole/17 hole.
