Company Profile
Yantai Sunny Rubber Co., Ltd established in 2005, located in Economic Development Area of Qixia City, Shandong Province. It is high-tech enterprise which shifted from military technology (Belonging to Nuclear industry system previously). Main products are pneumatically operated spillway gate, rubber dam and rubber belt products.
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:
1. Low cost and capital input, investment reduced by 30%-70%, save steel by 30%-50%, cement saved by about 50%, wood saved by over 60%.
2. Short construction period: air bladder installation generally need only 3-15 days, the project can be accomplished and attract benefits in the same year.
3. Dam body is made of flexible materials with shock resistance and foundation anti-deformation capability, good sealing effect, complete collapse capability, and no water resistance.
4. Used for urban river construction, the colors and beautiful styles are conductive to create features and beautify the environment.
5. The service life is designed up to 15 years, usually with less maintenance and management convenience.
The whole dam air bag strength
- There is no weak part in the dam bag, the performance is obviously improved, and the operation is safe and reliable.
- The dam bag is flat, without knot and bulge, the appearance is more beautiful.
- The thickness of the dam bag is even, so there is no need to use rubber pad for anchorage installation, which saves material and time.
- Production efficiency has been greatly improved and shortened the delivery time.
- Lower the cost, save the overall investment and get more benefits.
