The price of HDPE geomembranes depends primarily on thickness, the applicable standard (National Standard, Municipal Construction Standard, or non-standard), and the grade of raw materials; prices generally range from approximately 2 to 30 RMB per square meter.
Reference prices vary significantly based on thickness and specifications; here is a breakdown of common scenarios:
Thin (0.3mm–0.5mm): Commonly used for aquaculture pools and fish ponds; prices range from roughly 1.5 to 5 RMB/m².
Medium-thickness (0.75mm–1.5mm): Frequently used in water conservancy and environmental protection projects, with a wider price range. For example, a 0.75mm sheet is about 7 RMB/m², 1.0mm is about 9 RMB/m², and 1.5mm is about 13.5 RMB/m² (based on 2022 Municipal Construction Standard reference prices). If made from virgin resin to the National Standard, the price for a 1.5mm sheet rises to 17–19 RMB/m².
Thick (2.0mm and above): Used for high-standard projects like landfills; prices are typically above 10 RMB/m², depending on the specific standard.
Here are some actual price examples to give you an idea:
Raw material grades cause significant price differences: For the same 1.5mm thickness, a sheet made from virgin resin costs about 17–19 RMB/m², while one made from secondary-grade material is about 14 RMB/m², and one made from mixed-grade material is about 12.8 RMB/m²—so thickness isn't the only factor.
Applicable standards are a key price differentiator: A 0.3mm geomembrane meeting the National Standard costs around 28 RMB/m², whereas a non-standard or basic aquaculture-grade sheet might cost only a few yuan.
Minimum order quantities on online platforms affect unit prices: On platforms like Alibaba, you might see quotes of 1.67 RMB/m² for 0.5mm sheets and starting at 4.41 RMB/m² for 1.5mm sheets, but these usually come with minimum order requirements (e.g., a minimum purchase of 1,000 m²).
