*Weather resistance for webbing depends on fiber—nylon resists moisture, cotton does not.
Types of Strapping Material: Explained
Steel Strapping
Overview
Steel strapping remains the benchmark for heavy-duty load securing. It is made from high-tensile or stainless steel, available in various widths and thicknesses.
Best Uses
- Securing industrial equipment and machinery
- Shipping steel coils or construction materials
- Highly rigid, heavy, or sharp-edged items
- Railroad and oversized shipments
Features
- Maximum break strength and no stretch ensures stability
- Handles extreme temperatures and sharp load edges
- UV and moisture-resistant (will not degrade outdoors quickly)
- Requires metal tools and seals
- Can corrode if uncoated and cause rust stains
- May cause damage to delicate items due to lack of flexibility
Polyester (PET) Strapping
Overview
Polyester strapping is a versatile synthetic option, often made from recycled plastics (frequently giving it a green tint). It is suitable for medium to heavy-duty applications and is a cost-effective substitute for steel in many cases.
Best Uses
- Palletizing, stabilizing, and reinforcing heavy loads (lumber, bricks, beverages)
- Shipments that may settle or shift in transit
- Large warehousing operations
Features
- High tensile strength with greater elongation than steel
- Higher retained tension—continues holding tight on shifting loads
- Significant recovery (returns almost to original length after stretch)
- Resistant to UV and weather for outdoor storage
- Safer edges compared to steel
- Compatible with manual, battery-operated, or automated tools
Polypropylene (PP) Strapping
Overview
Polypropylene strapping is the most affordable option, designed mainly for light to moderate load securing. Available in numerous colors and core sizes, this strapping is especially common in high-throughput, automated settings.
Best Uses
- Bundling printed materials, textiles, and food products
- Securing cartons, boxes, and poly bags for short-haul shipping
- Millwork, flooring, direct mail, and pharmaceutical bundles
Features
- Highest elongation among plastics (stretches before breaking)
- Prone to “dead stretch” if overstressed—does not fully snap back
- Lightweight and easy to handle
- Typically embossed for grip and dust reduction
- Sensitive to UV and high temperatures unless specially treated
Woven Polyester/Polypropylene Strapping
Overview
Woven strapping uses multiple synthetic fibers interlaced to deliver both strength and flexibility. It’s ideal where loads are irregular in shape or settling is expected.
Best Uses
- Odd-shaped loads (machinery, pipes, furniture)
- Agriculture (bales, fresh produce)
- Eco-friendly and reusable applications
- Export shipments (often accepted by international regulations)
Features
- Strong load-bearing capacity with excellent shock absorption
- Breathable to prevent moisture accumulation
- Highly resistant to cutting and abrasion
- Can be re-tensioned and reused
Webbing: Cotton, Nylon, and Poly Webbing
Overview
Webbing is strapping used mainly for clothing, bags, upholstery, and sometimes specialty bundling. It’s valued for flexibility and comfort in wearable and furnishing products.
Best Uses
- Bag straps, belts, and handles
- Furniture webbing and reinforcement
- DIY, craft, and home décor projects
Features
- Soft to the touch, available in many textures and colors
- Cotton webbing is gentle but less weather-resistant
- Nylon is especially strong, resists mildew and stretch
- Polyester webbing combines weather resistance and strength
Comfort, Care Tips, and Specialty Considerations
Comfort and Usability
- For wearable strapping (bag handles, belts, harnesses), soft fibers (cotton, nylon, or smooth polyester) are preferable.
- Industrial strapping (steel, PET, PP) prioritizes strength over comfort—always use gloves and the right safety equipment.
- Woven and webbing types can be selected in different widths for ergonomic handling.
Care Tips
- Steel strapping should be stored dry and inspected regularly for signs of rust. Always dispose of cut steel pieces appropriately to avoid injury.
- Plastic strapping should be kept away from direct sunlight unless labeled UV-resistant.
- Webbing can often be machine-washed (for cotton) or easily wiped clean (for nylon/poly), but always check material guidelines.
- Woven strapping can be reused if undamaged.
Selecting for Clothing or Home Uses
- Prefer cotton or nylon webbing for applications against the skin or where aesthetics matter.
- Upholstery webbing should be strong, with little stretch, and match the furniture’s load needs.
- For DIY bags or straps, polyester or cotton webbing combines strength and appearance.
Practical Tips and Best Practices
How to Choose the Right Strapping Material
- Assess Load Type and Weight
- Heavy, sharp, or shifting loads: Steel or high-tensile polyester
- Medium-weight, rigid loads: PET
-
Lightweight, consistent loads: PP or webbing
-
Consider Transportation and Storage
- Long-distance, rough handling: Favor steel or PET
-
Short routes, gentle handling: PP may suffice
-
Evaluate Environmental Conditions
- Outdoor or damp: Use PET, coated steel, or treated webbing
-
Sun exposure: Choose UV-resistant materials
-
Decide on Application Method
- Manual jobs: Woven, webbing, or light plastics with buckles
-
High-volume or automation: Look for strapping compatible with strapping machines
-
Review Safety Requirements
- Use edge protectors with steel or plastic strapping to prevent damage to cartons
-
Always cut away from yourself and wear safety gloves
-
Factor in Reusability and Disposal
- Woven and webbing strapping can often be reused
- Steel and plastic strapping may require proper disposal after use
Using Strapping Effectively
- Don’t over-tension polypropylene—this can cause permanent stretch and reduced load security.
- Use the appropriate tool (manual tensioners, sealers, combination tools, or automated machines) for the strapping type and workload.
- Match the width and thickness of the strap to the application and the tension required.
- Incorporate edge protectors on sensitive products to avoid strap-induced damage.
- Inspect loads during transit or storage for slack or damage to strapping.

FAQ
What is the strongest type of strapping material?
Steel strapping is the strongest commonly available type, ideal for industrial, heavy-duty, and high-tension applications such as shipping steel coils or machinery.
When should I use polyester (PET) strapping instead of steel?
Polyester is preferred for medium to heavy loads that might shift or settle during transit. It provides strong tension, some flexibility, and less risk of damaging products compared to steel.
Is polypropylene (PP) strapping suitable for outdoor use?
Standard PP strapping is sensitive to sun (UV) and high temperatures, but specialized formulations are available for outdoor use. For most outdoor needs, polyester or woven strapping is preferred.
How do I choose the correct width and thickness of strapping?
Choose wider and thicker strapping for heavier or more awkward loads. Your choice should align with the tension your load needs and the compatibility of your strapping tools or machines.
Can I reuse strapping material?
Woven strapping and some webbing can be reused if undamaged. Steel and plastic straps are typically single-use since removal often damages them.
How should I store strapping materials?
Keep all strapping in a cool, dry place away from direct sunlight and chemicals. For steel, especially, prevent exposure to moisture to avoid rust.
What tools do I need for applying strapping?
For manual strapping: tensioners, sealers, and cutters. For high-volume operations: strapping machines or automated tools. Woven and webbing strapping often use buckles or ratchets.
Are there safety concerns when working with strapping?
Yes. Always wear gloves and eye protection, especially when cutting steel strapping. Use edge protectors to prevent strap-induced damage and potential injuries.
Is strapping recyclable?
Steel and many plastic strapping materials are recyclable. Check local guidelines and clean straps of contaminants before recycling.
What are the main differences between webbing and industrial strapping?
Webbing is intended for use in crafts, wearable items, and furnishings, prioritizing comfort and flexibility. Industrial strapping focuses on strength, tension, and securement of heavy or large loads.
With proper selection and handling, strapping material is a reliable, cost-effective solution for securing, bundling, and reinforcing a vast range of products and applications.
