ABRASION RESISTANT/WEAR PLATE

These are an advanced range of higher abrasion and wear resistant plates designed as per hardness level. Produced through cutting-edge Quenched or Quenched & tempered process. Products possess an exceptional combination of higher hardness & toughness, optimally designed chemistry, coupled with superior dimensional tolerances which helps in ease of fabrication. Wear-resistant Steel Plate products for application in Yellow Goods & Mining Equipment (Dump Body Trucks, Bulldozer Buckets, Crushers, Mixers, Loaders, Shovels) and Material Handling Equipment (Chutes, Hoppers, Body Liners).

HIGH STRENGTH PLATE

These plates are very high strength structural steel and can result in greater load-carrying capacities and lighter structures when used in place of conventional structural steel.

SHEET PILE

Sheet piles are thin interlocking steel sheets used to construct a continuous barrier in the ground to retain earth/water. Interlock is typically achieved by clutching the edge of one pile into the previous pile. Vibratory hammers are used to install sheet piles.
