When buying tarpaulin for any purpose whether for agriculture, transport, or construction understanding the term GSM is crucial. It’s one of the most important factors in determining the quality, durability, and application of a tarpaulin.
In this blog, we’ll explore what GSM in tarpaulin means, how it impacts the product’s functionality, and how to select the right tarpaulin GSM for your needs.
What Does GSM Mean in Tarpaulin?
GSM stands for Grams per Square Meter, which is a measurement of the weight of the tarpaulin material per square meter. It gives an indication of the material’s density, thickness, and durability.
In simple terms:
- Higher GSM = Thicker, heavier, and more durable tarpaulin.
- Lower GSM = Lighter, more flexible tarpaulin.
For instance, a 120 GSM tarpaulin is lightweight and suitable for short-term uses, whereas a 250 GSM tarpaulin is heavy-duty and designed for long-term or demanding applications.
Why is GSM Important in Tarpaulin?
Knowing the GSM of a tarpaulin helps you make an informed choice based on your specific needs. Here’s why GSM matters:
Durability and Strength
Higher GSM tarpaulins are stronger and can withstand tough weather conditions, making them ideal for outdoor applications like covering machinery or constructing geomembrane pond liners.
Purpose of Use
Lower GSM tarpaulins (e.g., 90–120 GSM) are suited for temporary or lightweight applications, while higher GSM tarpaulins (e.g., 250 GSM or more) are perfect for heavy-duty, long-term use.
Waterproofing
Higher GSM tarpaulins generally offer better waterproofing, ensuring your materials or goods stay protected during heavy rain.
Cost Efficiency
While higher GSM tarpaulins may cost more upfront, their durability and long lifespan make them a cost-effective choice for demanding applications.
Understanding GSM Ratings
To help you understand how GSM impacts usage, here’s a breakdown of common GSM ratings:
| GSM |
What It Means |
Ideal Uses |
| 90-120 GSM |
Lightweight, easy to handle |
Temporary shading, covering small items or furniture |
| 150-200 GSM |
Medium-duty, moderately durable |
Covering vehicles, construction materials |
| 250+ GSM |
Heavy-duty, highly durable |
Industrial applications, long-term outdoor storage |
For example, 120 GSM means the material weighs 120 grams per square meter. This makes it light and flexible, best suited for non-intensive uses.
Applications of Tarpaulin by GSM
1. Agriculture
- Low GSM Tarpaulins: Used as crop covers or lightweight agricultural shade nets.
- High GSM Tarpaulins: Serve as geomembrane pond liners in fish farming and irrigation ponds.
2. Transport and Storage
- Medium- to high-GSM tarpaulins are commonly used as truck covers, protecting goods from weather and road dust.
3. Construction
- High-GSM tarpaulins are ideal for covering building materials, scaffolding, and roofs during construction projects.
Factors to Consider When Choosing Tarpaulin GSM
When selecting a tarpaulin, keep the following factors in mind:
1. Material Quality
2. Application Purpose
- For lightweight, short-term needs, choose tarpaulins with 90–120 GSM.
- For demanding, heavy-duty applications, opt for tarpaulins with 250 GSM or more.
3. Environmental Conditions
- If you’re in an area prone to heavy rainfall or strong sunlight, high-GSM tarpaulins are the best option.
Conclusion
Understanding GSM in tarpaulin is essential for making the right purchase. Whether you need a tarpaulin for lightweight shading, heavy-duty storage, or constructing geomembrane pond liners, GSM is the key factor that determines its suitability.
Remember:
- Lower GSM (90–120): Best for temporary or lightweight uses.
- Medium GSM (150–200): Ideal for general-purpose applications.
- High GSM (250+): Perfect for demanding, long-term applications.
By considering GSM alongside other factors like material type and environmental conditions, you can ensure your tarpaulin meets your specific needs effectively.
So next time you shop for a tarpaulin, check the GSM and make an informed decision!
