Plastic Truck Bed Liners: Pros And Cons

what is truck plastic bed liner

A truck bed liner is a layer of protection that covers the floor and sides of a truck's cargo space, safeguarding it from impact damage, abrasive damage, dings, dents, and scratches. The two main types of bed liners are drop-in and spray-on/in. Drop-in bed liners are made of plastic or a hard, light composite material and are installed with minimal preparation, whereas spray-on bed liners require specific preparation and are applied by a professional using a roller, low-pressure cartridge, or high-pressure machine. Spray-on bed liners are made of polyurethane or polyurea and are considered more effective at protecting the truck bed from damage and corrosion.

Spray-on bed liners

The texture of spray-on bed liner materials can vary from smooth for easy cleaning to rough to prevent skidding. The thickness of the coating can range from 1/16 inch to 1/4 inch, depending on the application. Thinner coatings are more susceptible to chipping and cracking, while thicker coatings will alter the shape and size of the truck bed. For optimal thickness, Armor Thane recommends 1/4 inch on the bed and wheel wells and 1/8 inch on the sides for trucks with the most rugged use.

There are various brands and products available for spray-on bed liners, such as LINE-X, which offers a range of protective coatings and colour options. Herculiner's Professional Grade Bed Liner Kit is another option that can be sprayed or rolled on and is known for its durability and fade resistance.

Drop-in bed liners

"Drop-in" bed liners are one of the two broad classifications of truck bed liners, the other being "spray-on/in". Drop-in bed liners are installed into a truck bed with limited preparation work and can be easily removed for cleaning. They are often constructed of plastic, such as high-density polyethylene (HDPE), or some hard, light composite material. HDPE is a popular choice as it is recyclable, safe, and long-lasting. DuraLiner, for example, manufactures its drop-in bedliners from a proprietary blend of plastic that is 100% recyclable. Drop-in liners are custom-fit, one-piece shells that offer protection to the bed's side walls and the cargo floor. They are also easy to install and remove. The price of drop-in liners ranges from about $250 to $500.

While drop-in bed liners are easy to install and remove, they may not offer the same level of protection as spray-in liners. Some users have reported that items tend to slide around more easily on drop-in liners, and there is a risk of ripples or bowing forming over time. Additionally, if gravel, sand, or other debris get between the drop-in liner and the truck bed, it can cause rust underneath.

However, spray-in liners also have their drawbacks. They require specific preparation, including sanding, to ensure proper adhesion to the truck bed. If not applied correctly, spray-in liners can bubble or peel, and they may not be as durable as drop-in liners.

Ultimately, the choice between a drop-in or spray-in bed liner depends on the user's preferences and how they plan to use their truck bed. Drop-in bed liners offer a convenient, removable option that provides good protection for the truck bed, while spray-in liners offer a more permanent solution that may provide better protection against dents and scratches.

Carpet mats

A truck bed liner is a protective layer applied or installed into a truck bed to safeguard it against impact and abrasive damage. One option for a truck bed liner is a carpet mat, also called a "bed rug". Carpet mats are easy to install, and they can be purchased for as little as $120 for bed-only coverage, with full-coverage mats costing up to $500.

BedRug mats, for example, are made from a blend of soft, comfortable surfaces with industrial-grade durability, providing advanced waterproof and weather-resistant protection. The closed-cell foam backing is impervious to water, oil, and chemicals, ensuring that the truck bed stays dry and protected. This feature is particularly useful for those who use their trucks in harsh weather conditions, as it provides peace of mind that the cargo remains intact. The waterproof design is further enhanced by UV-resistant materials that prevent fading or degradation, even after prolonged exposure to the sun.

Smartliner mats are another option, crafted from a blend of rubber and plastic (LDPE - Low-Density Semi-Flexible Polyethylene). This combination ensures flexibility while maintaining the rigid shape and raised lip edge of the liners. They are manufactured to be completely odourless and carry a limited lifetime warranty.

Polyurethane coatings

The thickness of the coating can also vary depending on the application, ranging from 1/16 inch to 1/4 inch. Thinner coatings may be more susceptible to chipping and cracking, while thicker coatings can alter the shape and size of the truck bed. For trucks with rugged use, Armor Thane recommends a thickness of 1/4 inch on the bed and wheel wells and 1/8 inch on the sides.

Spray-on polyurethane coatings can also be used to protect other parts of a vehicle, such as fenders, bumpers, floorboards, and trim. They can also be applied to emergency vehicles, commercial transport, heavy construction, agriculture equipment, and boats. The colour options for polyurethane coatings are virtually unlimited, and an ultraviolet stabilizer can be added to maintain the appearance even in prolonged direct sunlight.

One example of a polyurethane coating is the RAPTOR Black Truck Bed Coating Kit, which is 10 times tougher than other bedliners and can be applied to almost any surface, including metal, plastic, wood, and concrete. It is also maximum UV resistant, so the colour won't fade.

Pros and cons of plastic bed liners

A truck bed liner is a protector applied or installed into a truck to safeguard it against dings, dents, scratches, and impact damage. There are two types of bed liners: "Drop-in" and "Spray-on/in". Drop-in bed liners are typically made of plastic or some hard, light composite material, and are removable for cleaning. Spray-on bed liners are made of polyurethane or polyurea and are applied directly to the cargo area surfaces.

Pros of Plastic Bed Liners:

  • Plastic bed liners are easy to install and remove, requiring little to no preparation work.
  • They are relatively inexpensive compared to spray-on bed liners.
  • Plastic bed liners are custom-fit, one-piece shells that offer protection to the bed's side walls and the cargo floor.
  • They are lightweight, which can improve fuel efficiency.
  • Plastic bed liners can be made from recycled materials, reducing plastic waste and consumption.

Cons of Plastic Bed Liners:

  • Plastic bed liners can scratch the pickup bed due to their hard, plastic surface that moves and shifts during travel.
  • They can trap debris and moisture underneath, leading to rust and corrosion.
  • Plastic bed liners may not be as effective at protecting against impact damage as spray-on bed liners.
  • The colour of plastic bed liners may not match the truck and can fade over time.
  • Thinner plastic bed liners may chip and crack, while thicker ones can alter the shape and size of the truck bed.

While plastic bed liners have their advantages in terms of cost and ease of installation, they may not offer the same level of protection as spray-on bed liners and can cause damage to the truck bed over time. It is important to consider the pros and cons before deciding which type of bed liner is most suitable for your needs.
