Manufacturers in this sector employ advanced technologies, such as CNC machines and heat treatment processes, to create button bits with precise dimensions and strength. The production begins with the selection of high-grade raw materials, followed by forging, heat treatment, threading, and finally, the insertion of the tungsten carbide buttons. Quality control is rigorous at every stage, with each batch undergoing stringent tests for hardness, toughness, and resistance to wear and impact.

Pultruded fiberglass grating is made using premium grade isophthalic polyester, vinyl ester or phenolic resin systems with a synthetic surfacing veil, making it corrosion resistant, lightweight, and durable. Pultruded fiberglass has a grit surface for safety, and a greater strength to weight ration than molded fiberglass grating. A 35% / 65% resin to glass ratio provides greater strength and less corrosion resistance than molded fiberglass. This product is better suited for longer life spans.
