Is there an expiry date for straps?

According to the NEN-EN 12195-2 standard, no specific lifespan has been set for lashing straps. It is important to regularly inspect the lashing straps for wear, damage and deformation. If there are signs of wear or damage, the lashing straps should be replaced immediately.

What is the STF value?

The STF value (Standard Tension Force) stands for the maximum tension force that is possible when lashing down. It is generated by the SHF (Standard Hand Force) of 50daN. The pre-tensioning force presses the load onto the loading surface and increases the frictional force between the load and the loading surface. The STF value of the straps is used in calculating the number of straps required to tie-down cargo.

What does daN stand for?

daN is an abbreviation of the force required to accelerate a mass of 1 kilogramme by 1 metre per second squared. It is a unit of measurement often used to indicate the strength of lashing straps. For example, a lashing strap with an STF value of 500 daN can withstand a force of 500 kilograms.

How do I know which ratchet strap I need?

There are many different types of lashing straps on the market, each with their own characteristics and applications. Here are some factors to consider when choosing lashing straps:

  • STF rating: Choose lashing straps with an STF rating suitable for the load you are transporting.
  • Material: Lashing straps are available in different materials, including polyester, polypropylene and nylon. Each material has its own characteristics and advantages.
  • Width: The width of the lashing strap determines its strength and the amount of tension it can withstand.
  • Length: Choose lashing straps that are long enough to safely secure the load.
  • Closure: Lashing straps are available with different types of closures, including ratchets, buckles and hooks. Choose the closure that best suits your application.
  • Manufacturer: most importantly: Choose a manufacturer that sells only certified straps. Check the certificate online. You can find our certificates if you search for 'Cargo Control Company' on DGUV and TUV SUD websites.

Tips for using lashing straps safely:

  1. Only use approved lashing straps:

    Make sure the lashing straps you use are approved and have a readable label. Without a label you should NOT use the straps. 

  2. Inspect lashing straps regularly:

    Check lashing straps for wear, damage and deformation. If there are any signs of wear or damage, the straps should be replaced immediately!

  3. Keep the lashing straps away from chemicals, UV radiation and fire: 

    Lashing straps can be damaged by exposure to chemicals, UV radiation and fire. Store the lashing straps in a dry, cool place and keep them away from these substances.

  4. Use the right straps for the load:

    Choose straps with an STF rating suitable for the load you are transporting. Make sure the width, thickness and material of the lashing strap are suitable for the load.

  5. Secure the load:

    Make sure the load is securely secured before driving. Use the correct technique to secure the lashing straps and check that the load cannot shift.

  6. Check the tension on the lashing straps when you are on the road:

    Any vibrations or bumps can cause straps to lose tension.

  7. Use at least 2 lashing straps across the load:

    Always be sure the load is properly secured.

Custom printed lashing straps

Can lashing straps be printed?

Yes, it is possible to have lashing straps printed with a text or logo of your choice. It is possible to print the lashing straps with a company name, advertising messages or the truck registration number. This is a great way to draw attention to your company name or brand and give it extra visibility. Find out more about our customization service.

The costs for printing lashing straps vary per length and per type of strap. Contact us for more information.

Ergo ratchet strap

What is the difference between a lashing strap with standard and ergo ratchet?

An ergo-ratchet is a type of ratchet that has a longer handle than a standard ratchet. This provides more strength, safety and comfort when securing cargo. Because an ergo-ratchet requires a pulling movement to secure it, you can apply more pre-tension and therefore secure the load properly.
