A geosynthetics manufacturer built for export
SIGMA is a Chinese geosynthetics manufacturer and supplier specialised in the production of geomembranes, geotextiles, geocells and geogrids. Established in 1998, we have grown into one of the industry's leading geosynthetics factories, built on a commitment to high-quality products and efficient service for clients worldwide.
A specialist geosynthetics factory
We focus on geosynthetics and do it well: geomembranes and geotextiles as our core products, alongside geocells, geogrids, GCL, drainage and erosion-control materials. Production runs across our own modern workshops with dedicated geomembrane, engineering-fibre, geocell and geotextile production lines — so quality is consistent and capacity is real.
Our customers are contractors, distributors, project owners and traders who need dependable lining, reinforcement and drainage materials — and a manufacturer that can supply them at container scale, on time, with the test documentation to back them up. We warmly welcome new business partners worldwide to join our distribution network.
Tested in-house, verified abroad
SIGMA operates a national-standard laboratory for in-house quality control, with a strict system covering raw-material testing, the production process and final-product testing. The management system is certified to ISO 9001 and our products have passed CE certification.
Beyond internal control, product performance is regularly tested and analysed by authoritative testing organisations in Europe and the United States. That independent analysis of technical parameters guides engineering design and helps buyers specify the right material for each application.
