Short answer: GSM (grams per square meter) is the weight of a tarp per square meter. For PE tarpaulin, 80–100 gsm suits light, short-term covering; 120–150 gsm is the most popular range for general use; and 180 gsm and above is for heavy-duty, long-term or industrial jobs. The right choice depends on how the tarp will be used, how long it must last and your target price.
What does GSM mean for a PE tarp?
A PE tarp is made of woven polyethylene tapes laminated with PE on both sides. GSM tells you how much material is in one square meter. A higher GSM usually means a thicker, stronger and longer-lasting tarp – and a higher price per square meter.
PE tarp GSM chart: which weight for which use?
| GSM range | Grade | Typical uses |
|---|---|---|
| 80–100 gsm | Light duty | Short-term covering, painting, DIY, budget retail tarps |
| 110–130 gsm | Medium duty | General household and garden use, ground sheets, firewood covers |
| 140–160 gsm | Heavy duty | Truck and cargo covers, construction sites, warehousing, general export tarps |
| 180–250 gsm | Extra heavy duty | Long-term outdoor covers, industrial and agricultural covers |
| 250–350 gsm | Super heavy duty | Demanding industrial uses, large covers, liners |
Market habits also matter. Many North American buyers order around 120 gsm, while 150 gsm is a common all-round heavy-duty choice in many other markets.
Other specifications to check besides GSM
- Mesh density (for example 10×10, 12×12, 14×14 per square inch): a denser weave gives a smoother, stronger fabric.
- Denier (500–1800 D): the thickness of the woven tapes.
- UV treatment: essential for outdoor use. Gusense uses virgin PE with UV additive.
- Finishing: rope-reinforced hems, reinforced corners and eyelet spacing (usually every 1 m / 3 ft).
- Size tolerance: confirm whether the size is the cut size or the finished size after hemming.
How to compare tarp quotes from different suppliers
- Ask whether the GSM is for the fabric or the finished tarp.
- Confirm the raw material (virgin PE versus recycled material) and UV additive.
- Compare the same mesh density, color, eyelet spacing and packing.
- Check the container loading: for finished tarps, about 12 tons fit in a 20GP and about 28 tons in a 40HQ.
FAQ
What is the most popular tarp GSM?
For PE tarps, 120–150 gsm is the most popular range for general use.
Is a higher GSM always better?
Not always. A higher GSM is stronger and lasts longer, but it is heavier and costs more. Choose the lowest GSM that meets your use and service-life requirement.
How long does a PE tarp last outdoors?
With UV additive, a standard PE tarp typically lasts about 2 years outdoors, depending on GSM, climate and use.
