1. I produced the breaking formula bar mold, mold pile, the whole assembly, easy to transport, quick assembly, easy maintenance, the sturdy structure, large tensile strength. To achieve a multi-purpose module, providing customers with significant savings in the cost of investment. 2. The use of thicker end plates, flanges, connection solid, strong tensile force, the overall longitudinal reinforcement, good stability, tube deformation. 3. The use of integral rings, safe, reliable, thick running wheel, improve product quality, extend the service life. Features and Benefits:  1. I produced the breaking formula bar mold, mold pile, the whole assembly, easy to transport, quick assembly, easy maintenance, the sturdy structure, large tensile strength. To achieve a multi-purpose module, providing customers with significant savings in the cost of investment.  2. Our steel pole, with thick end plates, flanges, connection solid, strong tensile force, the overall longitudinal reinforcement, good stability, tube deformation.  3. The use of integral rings, safe, reliable, thick running wheel, improve product quality, extend the service life.  Conical steel specifications: Small end diameter (mm)  Wheelbase (mm)  Running wheel diameter (mm)  Length (m)  150  2000  600  6-10  170  2000  600  6-12  190  2000  600  7-12  190  2000  650  15-18  230  2000  650  6-9  310  2000  650  6-12  350  2000  680  6-12  Smaller steel specifications (DMD) Diameter (mm)  Wheelbase (mm)  Running wheel diameter (mm)  Length (m)  300  2000  600  4.5-9  400  2000  650  4.5-9  500  2000  680  4.5-9
