Reinforced Piles
Concrete is poor in tension, yet excels in compression. Combining concrete with the added beneficial characteristics of steel provides the ultimate composite that excels in both tension and compression. With the usage of high strength cement and high tensile steel, METRIC Reinforced concrete piles have excellent tensile strength and compressive strength. These attributes allow our piles to be significantly more durable during transportation, pitching and driving. METRIC reinforced concrete piles bring a peace of mind to our ever growing list of satisfied customers.
Prestressed Piles
The use of prestressing technology creates even, constant compression throughout the pile. The tensile stresses caused by the action of stress waves when driving is reduced by the prestress. The reduction of tensile cracks gives greater durability to the pile, particularly if the pile is submerged. The piles are better able to resist, without cracking, any tensile forces set up by the working loads, whether direct or due to bending, or by accidental loads .Prestressing also reduces lateral tensile cracks that may occur during handling or transportation. Moreover, METRIC prestressed piles are made with high strength concrete. Furthermore, less reinforcement is required to achieve similar structural capacity compared to normally reinforced piles. With prestressed piles, a more economical foundation design can be utilized with greater flexibility.
Benefits and Advantages
High Load bearing capacity
With the Application of high compressive strength concrete, METRIC piles allow higher load capacity for more economical design of foundation system.
Strong Pile joints
End plates which are designed for filler welding offer a more reliable joint than conventional piles
High Durability
As a result of high strength concrete, METRIC piles has higher resistant in corrosive soil.
