The workshop is 22,000 square meters, equipment 200 sets, workers 230. The company owns 11 patents for invention, 18 patents for utility. Our rubber dams, air bladder support gate have already been included in excellent project tender recommendation directory of national Ministry of Water Resources, passed the technical evaluation of National Water Resources Experts Committee. We provide comprehensive water management services such as river channel improvement, water purification,ecological restoration and landscape enhancement, and are widely used in nuclear power security, power station water storage, water conservancy flood control, sediment dredging and etc.With the full capacity of design, production, installation and after sales, more than 100 spillway gates were built by Sunny in domestic. Our products also export to Italy, Thailand, Philippines, South Africa, Argentina etc.

Rubber dam Classification

Advantages:
Rubber dam has the following characteristics compared with conventional sluice dam:
The whole dam air bag strength
The whole dam airbag, also called none overlap joints dam airbag. It produce according to the whole manufacturing technology, which realized by the super large curing press and the patented technology of folding and curing the sulfide. The whole dam bag has no second time splicing and vulcanization process, and the tensile strength of all directions can be consistent, so there is no obvious weak part, which will improve the safety greatly. The service life is fully guaranteed.
