Question 1

What exactly is composite strapping made of?

Accepted Answer

Composite strapping is a multi-component product consisting of high-tenacity continuous polyester (PET) filament yarns aligned in parallel, encapsulated within a tough polypropylene or polyethylene polymer jacket. This hybrid structure gives it the tensile core of polyester with the surface durability and weather resistance of the coating.

Question 2

How does composite strap compare to steel strapping in terms of strength?

Accepted Answer

Our composite strap matches and often exceeds the working performance of steel in real-world applications. While steel has a higher theoretical breaking strength per millimeter, it has zero elasticity  meaning it snaps under sudden shock loads. Composite strap's controlled elongation absorbs that shock, so in practice, secured loads stay secured longer, especially during rough road or sea transit.

Question 3

What breaking strength ranges are available?

Accepted Answer

We offer a full spectrum from 500 kg / 1,100 lbs for light bundling up to 2,500 kg / 5,500 lbs and beyond for heavy industrial applications. Widths typically range from 13mm to 32mm, with thicker profiles available for higher breaking loads. We can recommend the optimal spec once we know your cargo weight and transport mode.

Question 4

Is composite strapping reusable?

Accepted Answer

Composite strap is designed for single-use tensioned sealing  once it is friction-welded or buckled shut, the joint is permanent. However, if you use buckle-based closure systems (non-weld), the strap body can sometimes be reused for lighter subsequent applications, provided it has not been nicked or abraded. For multi-trip cargo, we recommend our reusable lashing systems instead.

Question 5

How does temperature affect composite strapping?

Accepted Answer

Our standard composite strap performs reliably from -40C to +80C. Extreme cold slightly increases stiffness but does not cause brittleness. At sustained temperatures above 80C, consult us  we offer high-temperature variants for applications like hot steel coil bundling or autoclave use.

Question 6

Will the strap damage painted or coated surfaces?

Accepted Answer

No  this is one of its biggest advantages over steel. The polymer jacket is smooth, rounded, and non-abrasive. It will not scratch powder coatings, pre-painted steel, anodized aluminum, or varnished timber. For ultra-sensitive surfaces, we offer a softer PE-jacketed variant.

Question 7

What types of seals or closures do you recommend?

Accepted Answer

There are two primary methods. Friction welding provides the strongest, most consistent seal and requires a pneumatic or battery-powered friction welder. Metal buckles are a lower-cost alternative suitable for lighter loads and manual operations. We supply both, and can advise based on your throughput volume.

Question 8

Can composite strapping be used for hazardous goods and chemical cargo?

Accepted Answer

Yes. Our composite strap is chemically inert and resistant to most acids, alkalis, solvents, and salt spray. It does not generate sparks when cut or tensioned, making it inherently safer than steel for bundling flammable or hazardous materials. However, always confirm specific chemical compatibility with our technical team.

Question 9

How does UV exposure affect the strap over time?

Accepted Answer

Our standard strap is UV-stabilized for 6-12 months of direct outdoor exposure without significant strength loss, thanks to advanced UV inhibitors blended into the polymer jacket. For multi-year outdoor storage or tropical sun conditions, we offer an enhanced UV-resistant grade with an additional protective additive package.

Question 10

What tools or equipment are needed to use composite strapping?

Accepted Answer

You need a tensioner (manual or pneumatic) to pull the strap tight and a sealer or friction welder to close it. A standard combination tool does both. If you already use steel or PET strapping tools, they are likely compatible  we can verify cross-compatibility if you share your current tool model.

Question 11

Is composite strapping recyclable or environmentally friendly?

Accepted Answer

The polyester core and polyolefin jacket are both technically recyclable, though they require separation in specialized recycling facilities. The strap's environmental advantage is more in its use phase  by replacing heavier steel, it reduces fuel consumption during transport, and by lasting longer on loads, it reduces product damage and the associated carbon cost of remanufacturing and re-shipping damaged goods.

Question 12

What is your minimum order quantity and typical lead time?

Accepted Answer

For standard widths and strengths, we accept orders from 500kg per SKU. Custom-printed straps typically require 1,000-2,000kg minimum. Lead time for stock sizes is 5-7 working days; custom specifications take 10-15 working days depending on the printing and profile complexity. We welcome trial orders to confirm compatibility before scaling.

Question 13

How should composite strapping be stored?

Accepted Answer

Store coils flat in a cool, dry environment, ideally between 5C and 35C, away from direct sunlight and sources of ozone (electric motors, welding equipment). Keep them in their original UV-protective packaging until use. Under proper conditions, the shelf life is over 3 years without measurable strength degradation.

Question 14

Can you provide third-party test certifications for our import or quality audit requirements?

Accepted Answer

Yes. We can supply ISO 9001 quality system certificates, SGS or TUV third-party test reports verifying tensile strength, elongation at break, UV resistance, and chemical composition. These are standard documentation we provide for every new client relationship and can be refreshed annually upon request.

Question 15

What happens if the strap fails on our cargo  what is your warranty or claim process?

Accepted Answer

We take every failure seriously. Our process is: (1) You provide photos of the failed strap, the load configuration, and application conditions. (2) We conduct a root-cause analysis  often failure is due to incorrect tool settings, sharp edge contact, or tension mismatch rather than material defect. (3) If our analysis confirms a material failure, we replace the product and credit the invoice. We also dispatch a technical advisor (remote or on-site) to ensure the root cause is resolved for your
