STEEL CORD RUBBER CONVEYOR BELT
The Versatile Steel Rubber Conveyor Belt from Qingdao Grand Rubbers Co., Ltd is expertly engineered to serve a broad spectrum of industries. This high-performance belt thrives in mining, harbors, coal production, agriculture, and various industrial sectors. Its outstanding versatility ensures it excels in metallurgy and the chemical industry. With its robust flame-retardant properties, this indispensable belt rises to occasions where rapid extinguishing is crucial, making it an unrivaled choice for safety-focused operations.

Structure
The steel cord conveyor belt is intricately composed of an upper covering layer, lower covering layer, reinforced steel wire rope for superior strength, adhesive layer for enhanced durability, and protective side glue.

Features
The steel cord conveyor belt boasts superior characteristics such as unparalleled tensile strength, remarkable impact resistance, excellent elasticity, and high wear resistance. Its low elongation rate ensures longevity, while the exceptional adhesion between rubber and steel wire rope guarantees seamless operation. With uniform tension in the steel wire ropes and outstanding slotting performance, this belt is your go-to solution for transporting massive, granular, and powdery materials over long distances and under high-stress, large-volume conditions.
Technical Standard
