What Are the Benefits of Using an 18oz Coil Truck Tarp vs a Standard Tarp?

An 18oz coil truck tarp is a heavy-duty PVC-coated polyester tarp specifically designed for transporting steel coils and other extremely heavy cargo. The “18oz” refers to the material weight per square yard, indicating a thicker, denser fabric compared to standard tarps. This added weight translates directly into higher tensile strength, better abrasion resistance, and longer service life under harsh hauling conditions.

Unlike general-purpose tarps, coil truck tarps are engineered for flatbed trucking environments where sharp edges, high wind exposure, and long-distance transport are common. Reinforced hems, extra D-rings, and heavy webbing are standard features, making them purpose-built rather than multi-use.

Material Strength Compared to Standard Tarps

One of the most significant benefits of an 18oz coil truck tarp is its superior material strength. Standard tarps are often made from lighter materials such as 10oz or 12oz vinyl, or even woven polyethylene. While these may be adequate for light or temporary loads, they struggle under the demands of steel coil transport.

The thicker vinyl coating and high-denier polyester scrim used in 18oz tarps provide exceptional tear resistance. This reduces the risk of tarp failure during transit, especially when the load shifts or rubs against the tarp surface.

Superior Protection for Steel Coils

Steel coils are among the most demanding loads to cover. Their weight, sharp edges, and sensitivity to moisture require specialized protection. An 18oz coil truck tarp provides a dense barrier that prevents water penetration, shields against road debris, and minimizes wind flap damage.

Standard tarps often fail in this application because they stretch, tear, or allow moisture to seep through seams. Over time, this can lead to rust, rejected loads, or costly insurance claims. Using a tarp designed specifically for coils significantly reduces these risks.

Enhanced Durability in Harsh Weather Conditions

Weather exposure is a constant challenge for flatbed drivers. Rain, snow, UV radiation, and extreme temperatures can quickly degrade lightweight tarps. The thick vinyl coating of an 18oz coil truck tarp offers excellent waterproofing and UV resistance, maintaining flexibility even in cold climates.

In contrast, standard tarps are more prone to cracking, fading, or losing tensile strength over time. This means more frequent replacements and higher long-term costs for fleet operators and independent drivers.

Reinforced Construction and Secure Load Coverage

Another key benefit of 18oz coil truck tarps is their reinforced construction. These tarps typically feature double-stitched hems, heavy-duty webbing, and closely spaced D-rings designed to handle high tie-down tension. This ensures the tarp stays securely in place, even at highway speeds.

Standard tarps may lack sufficient reinforcement, leading to pulled grommets or torn edges when subjected to constant vibration and wind pressure. For coil transport, secure coverage is not optional but essential.

Improved Safety for Drivers and Cargo

Safety is a major concern when hauling heavy industrial loads. A torn or flapping tarp can distract drivers, create road hazards, or expose cargo unexpectedly. The added weight and stiffness of an 18oz coil truck tarp help it remain stable during transit.

By reducing the likelihood of mid-route adjustments or emergency stops, these tarps contribute to safer driving conditions. Standard tarps, while lighter and easier to handle, do not offer the same level of security for high-risk loads.

Longer Service Life and Cost Efficiency

Although an 18oz coil truck tarp has a higher upfront cost, its extended service life often makes it more economical over time. Fewer tears, reduced repairs, and less frequent replacement translate into lower total ownership costs.

Standard tarps may appear cost-effective initially, but repeated damage and downtime can quickly outweigh any initial savings. For professional haulers, investing in a durable tarp is a practical business decision rather than a luxury.

Ease of Maintenance and Cleaning

The smooth vinyl surface of an 18oz coil truck tarp makes cleaning relatively straightforward. Dirt, grease, and road grime can be washed off without damaging the fabric. This helps maintain a professional appearance and prevents contaminants from transferring to sensitive cargo.

Lighter standard tarps, especially woven poly types, tend to trap debris and are more difficult to clean thoroughly. Over time, this can compromise both appearance and performance.

When a Standard Tarp May Still Be Suitable

While 18oz coil truck tarps offer clear advantages, standard tarps still have their place. For light loads, short-distance hauling, or temporary coverage, a standard tarp may be sufficient. They are easier to handle due to lower weight and can be useful as backup or secondary covers.

However, when transporting steel coils or other heavy industrial materials, the limitations of standard tarps become apparent. Choosing the correct tarp for the application ensures both compliance and peace of mind.

Choosing the Right Tarp for Your Hauling Needs

The decision between an 18oz coil truck tarp and a standard tarp ultimately depends on cargo type, route conditions, and long-term usage. For professional flatbed operations involving steel coils, the benefits of an 18oz tarp in durability, protection, and safety are difficult to ignore.

By matching tarp specifications to real-world hauling demands, drivers and fleet managers can reduce risk, protect valuable cargo, and improve overall operational efficiency.
