GSM in Tarpaulins – What is It & What to Consider While Buying?

Tarpaulins are made of various materials, which make them strong and durable depending on the purpose and objectives. You may see different combinations like HDPE Tarpaulins, LDPE Tarpaulins, Cross Laminated, and Multi-Layered Tarpaulins to manage the following conditions of very large, strong, flexible, heat resistant, and tough waterproof material.  

But how would you determine whether the strength of the Tarpaulin satisfies your use or purpose? Not the combination but many things that are used to determine the tarpaulin strength, such as the Tarpaulin’s thickness, the mesh’s density, and finally, GSM (Gram Per Square Meter). So, in this article, let’s find out what GSM is in Tarpaulins, how to determine the GSM, and how to choose the perfect one for your need.  

 What Is GSM Tarpaulin?

What is GSM in Tarpaulin?

Generally, Grammes per Square Meter is referred to as GSM. It has to do with how much tarp material weighs. The tarp will be more durable with a higher GSM value. One may argue that the GSM number is a crucial quality indicator. However, this does not imply that a greater GSM number is always better because different GSM numbers have varying application ranges. Here are some examples of typical GSM tarps and their uses.

Different GSM in Tarpaulins and Applications

Tarpaulins are available in a variety of sizes, compositions, forms, and hues. The tarpaulin GSM is the most crucial component. A greater GSM indicates a higher density, heavier heavy-duty canvas, and, generally speaking, a longer lifespan.

The GSM numbers often used for tarpaulins made of various materials vary. The following is a list of some GSM numbers typically used for tarpaulins made of various materials: 

Applications of HDPE Poly Tarpaulins

HDPE (High-Density Polyethylene) tarpaulins come in various GSM (Grams per Square Meter) weights, and their applications can vary accordingly. Here are some common applications of HDPE poly tarpaulins in different GSMs:

1. 80-100 GSM: 

  • Temporary ground cover: Lighter-weight HDPE tarps are suitable for providing temporary ground cover to protect surfaces during construction, painting, or landscaping projects.
  • Light-duty equipment or vehicle cover: They can temporarily cover small equipment, machinery, or vehicles.

2. 100-150 GSM:

  • General-purpose cover: Tarpaulins in this GSM range are commonly used for general-purpose applications such as protecting goods during transportation, covering outdoor items, or creating temporary shelters.
  • Agriculture and farming: They can be used for crop protection, greenhouse covers, or as nursery shade nets.

3. 150-200 GSM:

  • Medium-duty equipment cover: Tarps in this range are suitable for covering medium-sized equipment, machinery, or vehicles for extended periods, protecting weather elements.
  • Construction site covers: They can be used as construction site barriers, temporary walls, or as shelter covers for workers or materials.

4. 200-300 GSM:

  • Heavy-duty equipment cover: Tarps with higher GSM are capable of providing robust protection for large machinery, heavy equipment, or vehicles in demanding environments.
  • Industrial applications: They can be used as liners for ponds, reservoirs or as containment covers for hazardous materials.

5. 300+ GSM:

  • Extreme heavy-duty applications: Tarps with very high GSM are designed for heavy-duty applications, including covering industrial machinery, large storage areas, or providing weatherproofing for structures.

Note: The specific application and suitability of HDPE poly tarpaulins may vary based on factors such as size, thickness, and quality of the tarpaulin. It’s important to consider the specific requirements of your project before selecting the appropriate GSM weight.

Application of LDPE Tarpaulins

LDPE (Low-Density Polyethylene) tarpaulins are another type of poly tarpaulin that can be used for various applications. Here are some common applications of LDPE poly tarpaulins in different GSM (Grams per Square Meter) weights: 

1. 70-90 GSM:

  • Light-duty covers: LDPE tarps in this GSM range are suitable for light-duty applications such as covering outdoor furniture and small vehicles or as ground covers for picnics or camping.

2. 90-120 GSM:

  • General-purpose covers: Tarps in this range can be used for general-purpose applications like protecting goods during transportation, covering materials on construction sites, or as temporary weather barriers.

3. 120-150 GSM:

  • Medium-duty covers: LDPE tarps in this GSM range offer increased durability and are suitable for medium-duty applications such as covering larger vehicles and equipment or as temporary roofing during construction.

4. 150-200 GSM:

  • Heavy-duty covers: Tarps in this range provide enhanced strength and can be used for heavy-duty applications, including covering large machinery, industrial equipment, or as weatherproofing for temporary structures.

5. 200+ GSM:

  • Extreme heavy-duty applications: LDPE tarps with higher GSM weights are designed for heavy-duty use. They can be used for applications that require exceptional strength and durability, such as covering industrial equipment, creating outdoor storage areas, or as protective covers for agricultural purposes.

Application of Cross Laminated Tarpaulins
