PE tarpaulin is available in a range of thicknesses, and the commonly used thickness can vary depending on the intended application and requirements. Here are some general guidelines for commonly used thicknesses of PE tarpaulin:

1. Lightweight/Standard Duty: PE tarpaulins in this category are typically used for light-duty applications such as temporary covers, ground sheets, or basic protection. The thickness of lightweight tarpaulins generally ranges from 70 to 120 microns (0.07 to 0.12 mm).

2. Medium Duty: Medium-duty tarpaulins offer increased durability and are suitable for applications requiring moderate protection. They are commonly used as covers for vehicles, equipment, or as temporary roofing. The thickness of medium-duty tarpaulins is usually between 120 and 180 microns (0.12 to 0.18 mm).

3. Heavy Duty: Heavy-duty PE tarpaulins are designed for demanding applications that require superior strength and durability. They are commonly used for long-term outdoor protection, construction sites, industrial purposes, or as weatherproof covers. The thickness of heavy-duty tarpaulins typically ranges from 180 to 250 microns (0.18 to 0.25 mm) or higher.

It's important to note that these thickness ranges are general guidelines, and the specific thickness of a PE tarpaulin can vary based on the manufacturer, product specifications, and customer requirements. When selecting a tarpaulin, it's crucial to consider the intended use, environmental conditions, and load-bearing capabilities to ensure that the chosen thickness meets the necessary standards and provides adequate protection.
