Steel Cord Conveyor belts

Application
Steel cord Conveyor Belt are widely used in high strength, long distance and heavy load transportation of materials, and they are also used in high strength and short distance transportation of materials on special occasions. Convey materials in coal, mine, harbor, metallurgy, power station, chemical etc. field.

Heavy Duty ST Conveyor Belt: steel core belt for long distance conveyor

Steel Cord Conveyor belt are used in the following industries:
Cement, concrete plants
Quarry , gravel, sand ,iron ore
Coal, mining, road construction Machinery
Metallurgy, steel industry
Heating and power station
Garbage incineration plants
Recycling, compost industry
Chemical industry, port,etc.

Features:
-Suitable for large capacity loads over long distances at high speeds
-High tensile strengths available
-Low elongation with less take up required
-Excellent flexibility
-Excellent spicing efficiency
-Manufactured to AS1333 or DIN standards
