A tarpaulin is one of the most versatile protection materials you can own — but buying the wrong one can lead to wasted money and poor performance. One of the key factors that decides how well a tarp works is its GSM (grams per square meter). Understanding GSM helps you pick a tarp that is strong enough for your needs without being unnecessarily heavy or costly.
What is GSM and Why it Matters
GSM is the weight of the fabric per square meter. The higher the GSM, the thicker and more durable the tarpaulin. For example:
-
80–120 GSM: Light-duty use, great for temporary covers like protecting goods during short transport.
-
150–200 GSM: Medium-duty use, suitable for agriculture, garden covers, and long-term outdoor use.
-
250+ GSM: Heavy-duty use, perfect for industrial, marine, and extreme weather applications.
How to Decide the Right GSM
-
Consider Weather Conditions: For areas with heavy rainfall, strong winds, or intense sunlight, choose higher GSM.
-
Duration of Use: For long-term covering (months or years), invest in thicker material.
-
Ease of Handling: If you need to frequently fold, move, or store the tarp, a medium GSM may be more practical than a heavy one.
Extra Features to Check
-
UV coating for sun protection.
-
Waterproof or water-resistant layers.
-
Reinforced edges to prevent tearing.
Conclusion:
Choosing the right GSM isn’t about picking the thickest tarp available — it’s about balancing durability, weight, and ease of use based on your specific needs.
