Packaging & Shipping

Except good raw material, good production equipments and technology, the safe and user-friendly packing is also very important for sidewall belting. HYRUBBERS have been packing conveyor belt in standard way to ensure the belt is safe during transportation and storage period.

packaging:packed in rolls and covered by fabric water-proof cloth,or clients' requirement also be respected

shipping:within 10-20 days,or depends on the quantity

Accordance with different applications, we can produce different grades of belt as following:

1) Heat Resistant Belt

According to the temperature of working environments, we can manufacture 3 different grades heating resistant belt, including up to 120℃ grade (HR120), up to 150℃ grade (HR150), up to 180℃ grade (HR180) and up to 200℃ grade (HR200) .Generally used by cements and steel works.

2) Abrasion Resistant (≤90mm3) / super abrasion resistant (≤60mm3) Belt

Generally used for transport the hard or shaped materials, like iron ore, diamond, copper and other minerals.

3) Oil Resistant Belt

Generally used for wood, papermaking, oil-based grain transportation.

4) Acid/Alkali Resistant Belt

Always used in Chemical materials transportation.

5) Cold Resistant Belt

The belt can work in some cold environment, like Northeast of China, Russia and North European countries.

6) Fire Resistant Belt

Always used in underground coal mining, steel works and so on.

7) conventional Belt

Generally used for small powder, grain and block materials.
