Core Product Advantages: The Technical Support Behind the Success


√ Full Composite Materials, Super Strong Corrosion Resistance

The 3DFF® double-wall tank is made from FRP composite materials for both the inner and outer tanks, completely eliminating electrochemical and microbial corrosion. It is rust-free, prevents impurities from contaminating the fuel, requires no additional anti-corrosion maintenance, and provides peace of mind for long-term use.


3D Glass Fiber Technology, Dual Protection

The integrated molding process of 3D glass fiber fabric not only increases the tank's structural thickness and overall strength but also creates a uniform 3.5mm gap between the inner and outer layers. This is complemented by a 24/7, comprehensive liquid media leak detection system, ensuring dual protection and preventing soil and groundwater contamination. It easily meets environmental compliance requirements.


Super Strong Structure, Buried Pressure Resistance

The unique negative mold molding process ensures that the reinforcement ribs are integrally formed with the tank body, addressing the potential issue of rib detachment in underground environments. The addition of ground anchor straps and backfill gravel creates a buoyancy and pressure resistance system, making the structure stable and strong. No reinforced concrete tank pits are needed, allowing for direct burial under roadways.
