To provide the best factory price, please specify the profile type (Internal/Middle-set or External/Rearguard), geometric shape (Dumbbell, Center Bulb, or Flat Ribbed), dimensions (width $\times$ thickness, e.g., $250\text{mm} \times 8\text{mm}$), and your total order volume in meters. If your project has specific engineering blueprints or requires custom OEM profiles, enclosing your technical drawings will allow our senior engineers to deliver a precise quote within 24 hours.

FUFUJING (Foshan Nanhai Fufujing Plastic & Hardware Co., Ltd.) is a direct, specialized manufacturer with over 20 years of industrial extrusion experience since 2002. Our fully equipped manufacturing facility is located in the Yongkou Industrial Zone, Nanhai District, Foshan, Guangdong. By sourcing directly from our factory, you eliminate middleman markups, gain flexible OEM/ODM customization capabilities, and receive direct technical support from our engineering team.

For our standard catalog profiles (such as standard DB dumbbell or center-bulb series), the Minimum Order Quantity is highly flexible, typically starting from 100 rolls or a minor trial volume depending on raw material stock. For completely custom profiles requiring unique mold development, the MOQ varies based on cross-sectional weight. Please contact our sales team to discuss your specific infrastructure project needs.

FUFUJING PVC waterstops are extruded from premium, non-toxic vinyl compounds that offer vastly superior thermoplastic welding capabilities compared to rubber. While rubber requires complex vulcanization chemicals and heavy on-site splicing equipment, our PVC profiles can be seamlessly heat-welded on-site in minutes using a professional Waterstop Heater Blade and Jointing Jig, creating a continuous, leak-proof matrix with far greater resistance to ozone, chlorinated water, and acids.

Quality is our baseline. FUFUJING is an ISO 9001 certified factory. All our concrete joint waterproofing products undergo rigorous laboratory testing to ensure excellent physical properties that meet or exceed international specifications (such as ASTM and BS standards). Our high-grade PVC material exhibits a tensile strength of $\ge 14\text{ MPa}$ and elongation at break of $\ge 320\%$, making them perfectly suitable for high-pressure environments like dams, tunnels, reservoirs, and basements.
