Who are we?

Weishan Zhongtian Rubber &Plastic Co. Ltd., specialist in manufacturing MDPE Floater, HDPE Pipe, Small Gold Mining Ship, Dredging Steel Pipe, etc.

 

 

MDPE dredger Floater Features:

 

a) Good Flexibility, excellent impact resistance, particularly suitable for constructions in open sea

 

b) Light weight, easy to install and handle, lower costs for moving

 

c) With good floating, it can be used for sand dredging, mud dredging, sea water dredging using.

 

d) Higher corrosive resistance, longer working life, 3 times longer than steel floats

 

e) Lower costs, the cost performance is better than steel floats.

 

Choose floater because…

 

a) The only Chinese supplier, who add notch on the float surface, screw holes more stable, same costs and float longer life.

 

b) Corrosive resistance, fire safety with 746C grade of UL-94HB rule

 

c) Manufacturer as seller

 

d) Sizes available to fit a pipeline from 6 inches (152mm) to 35 inches (889mm).  

 

e) Other sizes of floats can be made upon request

 

f) No strict MOQ
