FAQ

Are you a manufacturer or a trading company?

Shandong Hongyue Environmental Engineering Co., Ltd. is a geosynthetic manufacturer in Dezhou, Shandong - one of China's main geosynthetic production clusters. We run blown-film, lamination, nonwoven, geonet and GCL lines and supply directly with test reports and certificates.

What is the manufacturer hotline?

Sales hotline +86 181 6202 5999 (Mr. Wang, WhatsApp available), email 498840623@qq.com. Please state application, product class, specification, quantity and delivery address for a one-shot accurate reply.

Which standard does the geomembrane follow?

Current standard is GB/T 17643-2025 (implemented 2025-11-01, replacing the 2011 edition). Composite geomembrane follows GB/T 17642-2025; filament geotextile GB/T 17639-2023; staple geotextile GB/T 17638-2017. GRI-GM13 property sheets are available on request for overseas projects.

How is the price determined?

There is no fixed price list. Price depends on resin grade (virgin vs recycled), standard level, thickness or weight, composite structure, order quantity, customization, distance and delivery terms, and testing/documentation services. Resin and fiber prices fluctuate and pass directly into ex-works price, so we quote per specification + quantity + destination + invoice requirement.

Do you keep stock and how fast is delivery?

Common thicknesses and weights are in stock; urgent orders load the same day. Non-standard widths, special thickness/weight, special structures or formulations are scheduled separately, typically within 7 days. Road transport covers all China; export orders load FCL from Qingdao or Tianjin port.
