We provide a diverse range of blades and side cutters crafted from various grades of high carbon and boron steel. Many of these products undergo heat treatment and hardening processes using both high carbon and boron steel to enhance their durability and meet the rigorous demands of earthmoving and mining applications.
Grader blades and side cutters serve as the primary working devices, alongside other auxiliary equipment, complementing each other to perform soil cutting, scraping, leveling, and delivery operations. They are essential for shaping and maintaining gravel roads, roadbeds, stripping topsoil or turf, trenching, scraping slopes, and leveling surfaces. Additionally, grader blades and side cutters can help prevent damage to the work area.
* 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.
