What is Composite Strap & Woven Lashing?

Composite Strapping is also referred to as synthetic steel, the latest development in strapping technology. The Composite Strap comprises strands of polyester fibres, all travelling vertically and coated together by clear polypropylene. Composite Strapping is available in various widths and strengths. The polypropylene coating increases its abrasion resistance yet allows for slight elongation during transit. Due to its polypropylene coating, the Composite Strap is much stiffer than the poly-woven strap. The Composite Strap and Galvanised Wire Buckle stiffness of the Composite Strap makes it easy to feed underneath pallets.

Woven Lashing Belts are made of high-tensile polyester yarns. Due to its material properties of low elongation (below 10%), it is highly tear-proof and absorbs very little moisture. Woven Strapping Belts do not splice and are flexible and universally applicable. Woven Lashing is a One-way cargo securing strapping with high tensile strength. It is perfect for securing heavy machines in shipping containers and flat-rack cargo.

All Wire Buckles are protected from corrosion, seawater, and other climatic threats. Wire Buckles are designed for easy threading and to deliver the ultimate high-load performance. Galvanised Wire Buckles are suitable for our Composite Strapping, while our Phosphate Wire Buckle performs best with polyester Woven Strapping.

How to use the Composite Strap?

First, prepare the strapping around the crate or box. Then, insert the end of the strapping up through the buckle centre and around the open leg to form a loop. Ensure the strap on top is on the shorter end and pull the top strap tight around the leg to pull both top ends of strapping in the opposite direction to apply tension can manually tighten using tensioners. (First thing you will want to be sure of is when holding the buckle facing the right-hand side, and one of the ways to remember that is by looking like a “C “.)

Second, position the manual tensioner on the bottom strap, about 30 cm away from below the buckle, and then take the tensioner tool to squeeze the handle to raise the gripper foot. That bottom strap will go underneath the gripper foot while the top strap goes through the cutter housing and the windlass.

After that, start tensioning the moment you have got it all the way tensioned and that buckle has started to collapse down on that strap. You can squeeze the handle of the tensioner to cut the strap and move the tensioner away. The legs of the buckle should close upon tensioning the strap if the buckle is made of good quality and hard steel. Inferior soft wire steel was used if the buckle was deformed or the legs were open (move up instead of down).

How to use Woven Lashing?

Take the buckle with your left hand. Feed the Woven Lashing through the buckle centre (upwards), away from you around the buckle, back up through the small upper opening, and towards you through the buckle centre (downwards).

Feed the bottom lashing (attached to the coil) through the centre of the buckle (upwards) towards you. Fold the lashing around the buckle and feed it up through the small bottom opening and the centre of the buckle (downwards). Pull the lashing hand tight.

After that, place the manual tensioner from the right side onto the bottom lashing. Push the handle to release the gripper foot, place the bottom lashing underneath the gripper foot and through the knife assembly and winger. Move the handle of the manual tensioner up and down and tension the lashing. When you have reached optimum tension, push the handle of the tensioner, and cut the lashing. Move the tensioner away to the right.

Benefits of using Composite Strap and Woven Lashing

Composite Strapping is light, flexible, without sharp edges, and can be used in countless applications. It is ideal for fixing and sealing fragile or fragile products. Composite Strapping is a lightweight textile material, which means it is easy to use and will not rust, rot or leave marks on the surface. It has a high resistance, with a maximum breaking strain of 1500kg, and is best used manually with a tensioner and sealer.

The main features and advantages of Composite Straps:

  • Cost-effective
  • Soft and flexible
  • It would not rust or rot
  • As strong as steel
  • High transverse strength
  • High shock absorption ability

Woven Lashing solutions have many advantages over conventional lashing products. They are safe, cost and time-effective, and easy to apply and eliminate cargo damage.

The benefits of braided lashing include the following:

  • The application is simple, fast and safe
  • Protected
  • Shock absorption
  • High retention tension
  • Lightweight

Applications for Composite Strap and Woven Lashing

Composite Strapping is used for goods that may expand, settle, or contract during transportation. If the load is sensitive to abrasion and will lose value if chipped or scratched, you should use polyester strapping since its material is not as hard as steel. If you have less experienced staff in applying or removing straps, Polyester Composite Strapping is a safe choice since it does not recoil when cut.

Woven Lashing is an economical and easy-to-operate alternative to traditional tension straps and complex wooden boxes for fixing loads. It is the most effective way to protect international shipping cargo on any transport unit (container, pallet, rail car, or ship). Woven Lashing can significantly reduce accidents and cargo damage. Lashing is steadily increasing as a method of securing loads in pallets and containers. It helps replace expensive multi-way straps and supports and replaces complex wooden boxes.

Case Studies

Compared with steel strapping, Composite Strapping provides consistent system strength because of the buckle’s joint closure. The wire buckle is the most vital joint closure of all strapping systems and is not dependent on the tool quality or operator. The system is easy, fast, and safe to apply with low maintenance and low-cost manual tooling. The Composite Strap is non-abrasive and can be applied directly to coated products.

Steel strapping has high linear system strength (strap only). Steel strapping depends on the crimper and tool for its system strength (strap + joint closure). System strength is, therefore, not consistent. Steel can be fast to apply. However, it is unsafe for workers and receivers. Due to its sharpness, it damages coated products.

Composite Strapping is used for light loads to tie up the items such as carton boxes and barrels. Woven Lashing is used for heavy loads to secure tied-up cargo and ensure that the goods will not be damaged during transportation.
