Laboratory tests were performed on Fiberglass Dock Post to determine the lateralflexural stiffness. The tested pile had a 38.7-centimeter (cm)- (15.25-inch-) diameter, and the steel reinforcement consisted of 16 25.4-millimeter (mm)- (1-inch-) diameter bars connected with a spiral. The free span between the two supports at both pile ends was 5.8 meters (m) (19 feet (ft)). During the testing, the load was applied cyclically at the middle of the free span.
The test results show that loads exceeding 222 kilonewtons (kN) (50 kips) caused permanent deflections in the pile. At these loads, yielding of the steel bars was initiated, inducing slippage in the recycled plastic. The ultimate lateral load-bearing capacity was 311 kN (70 kips), at which point the pile underwent fully plastic behavior. Further, the pile’s response was ductile up to this load, and the recycled plastic did not appear to crack during loading. Two axial laboratory tests were performed to obtain the buckling loads. The pile samples had diameters of 25.4 and 30.5 cm (10 and 12 inches) and lengths of 9 and 11 m (29.52 and 36.08 ft), respectively. Two loading cycles were applied to the 30.5- cm- (12-inch-) diameter pile sample to a maximum load of 2113 kN (475 kips) and 2228 kN (501 kips); the latter load caused the sample to experience failure. A third applied loading cycle caused this pile sample to buckle at 1841 kN (414 kips). The maximum applied load on the 25.4- cm- (10-inch-) diameter pile sample at which it experienced failure was 1392 kN (313 kips).
Reviewing the current state-of-practice within the framework of the current research with the manufacturers of the selected FRP piles illustrated the need for both laboratory and field axial loading tests to assess the engineering performance of these piles as axial load-bearing piles.

FRP vs Traditional Materials
Traditional building materials have their place. But for harsh, corrosive environments, FRP is a smart choice. Here’s how FRP compares to several traditional options
At LEADFRP, we believe that fiber reinforced plastic (FRP) products are the choice of the future. Compared with traditional materials such as steel and aluminum, it has excellent performance and service life.
LEADFRP provides a series of high-strength fiber reinforced plastic products (FRP), which are designed and manufactured to provide long-lasting performance in highly corrosive environments, while having the advantages of light weight and high dielectric strength compared with traditional structural materials.
Since 2001, we have provided our customers with innovative, high-quality composite designs and materials through two strategic offices/factories located in the United States and China. It is here that we provide turnkey solutions to take your product from concept to design, to mold calculation, manufacturing, and finally to installation. [More about manufacturing]
We own 5 acres (20000 square metre) standard plants, 80 sets of advanced various manufacturing and machining equipments, 120 sets of assembly pultrusion production line, including one 1000 kN tensile strength machine and one 200 kN bending and torsion machine. We also can proceed basic property test of different kinds of composite insulation materials according to GB, ASTM, etc standards. Our products passed TUV Rheinland type test and UL type test.
LEADFRP strictly carry out standardized, scientific and normalized management mode. We fully implement ISO9001 quality management system, ERP managing system and 6S management mode through the whole service cycle of contract signing, production, process inspection, finished product ex-factory, after-sales service, which outstandingly reflect ‘Quality is the Life of Enterprise’. We have ISO9001, ISO14001 and ISO45001 identification.
