Common Webbing Materials for Ratchet Tie Down Straps
Since its establishment in 2002, Zhangjiagang SMK MFG. Co., Ltd. has specialized in cargo securing and control products, leveraging over 20 years of professional experience and a global export network. It has become a trusted solution provider in transportation, logistics, outdoor, and industrial sectors. Among various cargo securing products, Ratchet Tie Down Straps are essential safety tools, and their core component—the webbing material—directly affects load capacity, durability, and safety performance.
Polyester (PET) Webbing
Polyester webbing is one of the most commonly used materials for Ratchet Tie Down Straps.
- High Strength and Low Stretch: Polyester fibers maintain stability under heavy loads, minimizing cargo movement and ensuring safe transport.
- Excellent Weather Resistance: Polyester has outstanding UV and moisture resistance, preventing aging from prolonged sun exposure or humid conditions.
- Chemical Resistance: Polyester webbing effectively resists oils, solvents, and other chemicals, extending service life.
In SMK's production system, polyester webbing undergoes rigorous tensile and abrasion testing, ensuring that each roll meets the Working Load Limit (WLL) standards and guarantees safe usage under various transportation conditions worldwide.
Nylon (Polyamide) Webbing
Nylon webbing, although with higher stretch, is favored for its excellent toughness and impact resistance in specific applications.
- Outstanding Shock Absorption: Nylon webbing can buffer short-term impact loads during cargo transport, reducing cargo damage.
- Strong Abrasion Resistance: Nylon fibers are durable, suitable for frequent friction or repeated tension scenarios.
- Versatility: Nylon webbing is used in industrial lifting, outdoor gear securing, and other environments, though moisture absorption can affect its load capacity.
In SMK's product line, nylon webbing is mainly used for applications requiring high shock absorption, such as off-road 4x4 equipment and industrial lifting slings. The company conducts humidity cycling and fatigue tests in its laboratories to ensure consistent performance under harsh conditions.
High-Strength Polypropylene (PP) Webbing
High-strength polypropylene webbing offers cost-effectiveness and lightweight advantages:
- Lightweight and Easy to Handle: PP webbing has low density, making manual handling and fast cargo securing easier.
- Chemical Resistance: Suitable for exposure to acids, alkalis, or marine environments.
- Ideal for Short-Term or Low-Load Transport: Although slightly lower in strength than polyester, it is widely used in light cargo securing and warehouse applications.
SMK optimizes PP webbing thickness and material selection to ensure reliable performance in light-duty cargo securing, providing diversified solutions for customers.
Webbing Processing and Surface Treatment
Besides material selection, processing and surface treatment of webbing are equally critical. SMK introduces advanced heat treatment and edge abrasion protection technologies in its production lines to prevent webbing edge wear and improve ratchet operation smoothness. Additionally, surface treatments such as anti-slip, waterproof, or reflective coatings can be applied based on customer requirements to expand application scenarios.

How to Properly Operate the Ratchet to Ensure Safety
Since its establishment in 2002, Zhangjiagang SMK MFG. Co., Ltd. has specialized in cargo securing and control products. With over 20 years of professional experience and a global export network, SMK has become a trusted supplier in transportation, logistics, industrial, and outdoor sectors. For Ratchet Tie Down Straps, safety relies not only on material and structure but also on proper operation.
Select the Appropriate Ratchet Tie Down Strap
Before use, select a strap suitable for the cargo type and transportation environment. SMK offers multiple load ratings and webbing widths, covering light-duty to heavy industrial applications. Users should refer to the strap’s Working Load Limit (WLL) and Breaking Strength (BS) to ensure it can handle the maximum load during transport.
All SMK products are ISO 9001 certified and rigorously tested in-house for tensile strength, abrasion, and environmental resistance to maintain consistent performance.
Inspect the Strap
Before use, inspect the strap for wear, damage, or aging:
- Webbing Inspection: Check for frays, cuts, abrasion, or chemical damage;
- Ratchet Inspection: Ensure the ratchet mechanism operates smoothly without rust or jamming;
- Hooks and Fittings: Verify that hooks are not deformed or damaged.
SMK designs ratchet mechanisms using corrosion-resistant steel and coatings and ensures compliance with multiple international standards for reliable operation in industrial and outdoor environments.
Correct Threading and Securing
Proper ratchet operation is key to cargo stability:
- Threading: Insert the webbing end into the ratchet slot, keeping it flat and untwisted;
- Hook Attachment: Secure both hooks to solid anchor points, ensuring the load direction aligns with the hook orientation;
- Tighten the Strap: Pull the webbing manually to remove slack and ensure contact with the cargo surface;
- Operate the Ratchet: Use the handle to tighten the strap to the required tension. SMK ratchets feature ergonomic handles for smooth operation, reducing fatigue while maintaining even tension.
Tension Control and Safety Check
While tightening, control tension to avoid overloading:
- Proper Tension: Webbing should be tight against the cargo without exceeding the WLL;
- Even Load Distribution: For long or multi-point secured cargo, use multiple straps to distribute force evenly;
- Recheck: Shake cargo gently to ensure stability and adjust tension if necessary.
SMK emphasizes ratchet load performance and anti-slip webbing design, ensuring cargo remains secure even during long-distance or rough transport conditions.
Proper Ratchet Release
After use, safely release the ratchet:
- Unlock the Ratchet: Flip the handle to the full release position;
- Slowly Rewind: Control webbing retraction to prevent snap-back or damage;
- Organize for Storage: Roll webbing flat to prevent tangles and damage, extending service life.
SMK ratchets include a quick-release feature, allowing efficient and safe operation in both industrial and outdoor environments.

Common Misuse of Ratchet Tie Down Straps Leading to Safety Hazards
Zhangjiagang SMK MFG. Co., Ltd. has specialized in cargo securing and control products. With over 20 years of experience and a global export network, SMK has become a trusted supplier for transportation, logistics, industrial, and outdoor sectors. Ratchet Tie Down Straps are recognized worldwide for their strength, durability, and reliability. However, improper use can create safety hazards. Understanding common misuse and proper practices can significantly reduce transportation risks.
Overloading
Using a strap below its Working Load Limit (WLL) or Breaking Strength (BS) is a common mistake.
- Risk: Overloading can cause webbing breakage or ratchet failure, potentially leading to cargo tipping or transport accidents.
- Protection: SMK Ratchet Tie Down Straps are rigorously tested and clearly marked with WLL and BS, allowing users to select the appropriate strap for the cargo.
Improper Ratchet Operation
Correct ratchet operation is essential. Common mistakes include:
- Not fully locking the ratchet: Leads to slack webbing and cargo movement;
- Over-tightening or rapid ratcheting: Can damage webbing fibers or ratchet components;
- Poor handle usage: Ignoring ergonomic operation, causing fatigue or accidental slippage.
