Butterfly Type Concrete Trench Drain Molds

Focus on agricultural water conservancy construction of concrete trench drain molds,The main style to butterfly design,Just like the wings of the butterfly to named,Made of Polypropylene material in injection process.

These sets of trench drain molds mainly with two identical arc arch module,After precast the concrete trench drain products,It will be a small semi-circular shape.

As the concrete pouring the overall area of the larger trench drain,The concrete blocks of finished products will be heavier,If only rely on the plastic structure of the concrete trench drain mold is easy to deformation,So in this respect,When designing the concrete trench drain steel mold,Targeted to do the bottom to strengthen the structure,Although the cost has increased,But the actual cost-effective more better than normal concrete trench drain mold.
