HDPE Square Sea Cages

High intensity Excellent flexibility Corrosion resistant Strongly resistant to the storm Long service life at least 10 years  

About the cage :

The cage pipes and cage accessories are straight pressure pipes made from HDPE rawmaterials especially suited for continuous use in harsh environments, and are based on decades of experience in pipe technology. The usuful life of the cage frame is at least 10 years.

About the nets :

Our nets are made from Nylon or PE net with global cutting-edged technology and are treated with anti-UV process, which guarantee the nets of high intensity, good security and long service life at least 8 years. Also, we can treat the nets with the antifouling process according to various demands from different customers in order to postpone another 6 months for the nets to be resistant to the biological adhesion under the normal condition, all of which guarantee the frequency of manual net change and lessen the labor intensity for it.We assembly the complete nets by 2 steps with hand. First we use the ropes made of PE6 for connecting the net , Secondly we use ropes made of PE16 and make the two sizes of rope joining together. We deal with the net by double layer in the place where we tie the sinker tube (with dropping stone) to the net.

About the mooring syetem :

We design the flexible rectangular rope-frame for mooring the cages and the  rope-frame can spread the force to the maximum extent to every single spot on the cage with the average power, rather than concentrating all the force on just one spot. The measure we take can make the cage keep balance on the water even on the circumstance of harsh marine environment and therefore providing the pledge for the nets security
