PURLoc™ is a structural fiberglass composite sheet pile manufactured by the pultrusion process and is designed to be able to weather the harsh marine environment.  Many traditional methods of building seawalls from wood, steel, and even concrete simply cannot hold up over time.  Marine borers attack and eat the wood, steel will rust and corrode, and concrete will deteriorate over time as the rebar starts to corrode.  Strict environmental laws have prohibited the use of chemically treated wood and other solvent based paints or coatings.  The shortened life cycle of traditional materials has increased the costs for maintenance and replacement.  PURLoc™ sheet pile does not leach any chemicals making it environmentally safe.  PURLoc™ is a cost effective and a long term solution to any waterfront project.

PURLoc™ is the first composite sheet pile to use a special patented urethane injection box.  What makes the injection design significant is that it permits resin to be injected through the most dense layers of roving and fabrics.  Other injection systems cannot penetrate these reinforcement packages and therefore do not achieve the wet-out necessary to meet the mechanical properties desired.  In addition to working with traditional thermoset resins, it works best with the pure polyurethane family of resins where glass contents are much higher at 76 to 80 percent.  Traditional injection systems cannot possibly inject through this high percentage of dense rovings and mats.  This allows the PURLoc™ system to have properties that are 30% stronger than any other FRP sheet pile on the market.  The PURLoc™ line of sheet pile uses a proprietary non-hybrid Polyurethane resin system that is exclusive to Gulf Synthetics.  Baydur® PUL 2500 resin is used and manufactured by Bayer Material Sciences.  Compare our Modulus of Elasticity and Tensile strength to other similar profiles and you will see the remarkable difference.

High-pressure pipes 

Maximum working pressure 300 MPa (43 500 psi)

The range of SKF High-pressure Pipes covers most applications where there is a requirement to transfer oil at high pressure. They consist of a steel pipe with a steel ball fitted to both ends. Two swivelling connection nipples press these balls against the seating of the connecting hole and thus sealing against oil leakage.

  • Wide range of pipes
  • All pipes are pressure tested during production
  • Special lengths (up to 4 000 mm / 157 in) made on request

Safety note

For safety reasons, these high–pressure pipes have a maximum service life. All SKF High-pressure Pipes are hard–marked with the year in which their service life expires e.g. Do no use after 2021.

High pressure pipes are marked with their maximum working pressure e.g. MAX 400MPa.

The pipe colour also indicates the maximum working pressure. Black pipes can be used up to 300 MPa, whilst grey pipes can be used up to 400 MPa.

Z-Type Steel Sheet Piling

Z-shaped sheet piles are called Z’s, because the single piles are shaped roughly like a horizontally stretched Z. The interlocks are located as far away from the neutral axis as possible to ensure good shear transmission and increase the strength-to-weight ratio. Z piles are the most common type of sheet pile in North America and can be used in a wide variety of applications. Retaining walls, cofferdams, parking garages, environmental barrier walls, and bulkhead walls for ports are just a few of their varied uses.

What Is Sheet Piling?

What Is Sheet Piling? Sheet piling refers to the construction of a wall, temporary or permanent, that uses thin, interlocking steel sheets known as sheet piles. These sheet piles lock together and are then driven vertically into the ground, forming an effective retaining wall.


Sheet piles are thin sheets of material with interlocks built onto both of its ends. They can be made from wood or concrete, but the most commonly used sheet piles are made from steel. The interlocking design on their sides allow the sheet piles to connect to each other to form a continuous wall.


Sheet pile walls can be temporary or permanent. Temporary walls help prevent cave-ins at confined works sites and provide both easy access to the site and protection to the workers. Permanent walls support basement walls and prevent flooding along shorelines. Construction companies also use permanent sheet pile walls for home foundations and stabilizing a sloping terrain.


Sheet piles are cheap and recyclable. Builders are able to assemble sheet pile walls easily, and they are able to erect a wall of any length quickly. Sheet pile walls are also very durable and are capable of retaining both water and earth while resisting their pressures.

What are the characteristics and scope of the steel sheet pile?

Some of us are usually new to the steel sheet piling of this material, when in fact it is not very understanding itself? Especially for such a large material, it features support what is, to what extent does it apply to? Try the following detailed description, we hope to give you some help.

Maintenance of steel sheet piling wall, Larsen steel sheet piling is composed of positive and negative buckle or lap side thereof. Usually seen Larsen steel sheet piling length of 12 meters, 15 meters, 18 meters less than does a rather long channel pile steel sheet piling is between 6 m to 9 m, type and length is determined by the calculation . Because the steel sheet piling it has good durability, usually in the pit backfill after construction is completed, it can still pull out the steel sheet piling for recycling, which can be used until the next time you can come up again to use. And precisely because it is a lot easier with the construction, but also shorten the construction period of time, so the steel sheet piling widely welcomed by everyone. Channel steel sheet piling retaining can not, if the ground water level is slightly high point we will take the program to control the water level, you can usually impermeable or precipitation can achieve this effect.

Channel steel sheet piling its flexural capacity is relatively weak, it is usually used for the trench is less than about 4 meters. And Larsen steel sheet piling is relatively strong resistance to bending. At the top is provided some support, support small stiffness, will open after deformation, this time in radians also become large.

We understand these things and then, for the purchase of steel sheet pilings may be easier and more simple. With the increasingly rapid development of modern technology, there is reason to believe that the future can be even higher in the future to update technology to solve more difficult problems now.

Special Application of Steel Pipe Piles – Retaining Walls

Steel Pipe Pile Walls

Steel pipe pile walls consists of a steel pipe and clutches welded on either side of the steel pipe. One SPSP is connected to the next one by interlocking their clutches. The most commonly used clutches are the P-P, P-T and L-T types.


Steel pipe piles can also be joined into continuous retaining walls by connecting them with conventional sheet piles as intermediate sections. These combined walls have enhanced resistance to vertical and horizontal loads compared to the conventional sheet pile sections. They can be used as quay walls, breakwaters, temporary cofferdams, retaining walls, bridge foundations, and other various civil engineering structures.
