Frequently Asked Engineering & Sourcing Questions
Key answers regarding factory direct supply, testing benchmarks, custom manufacturing, and global shipping arrangements.
What geosynthetic products does Changhong manufacture?
We manufacture smooth, textured (coarse surface) and dual-color geomembranes in HDPE, LDPE, LLDPE and EVA, needle-punched non-woven and polyester long-fiber geotextiles, HDPE geocells, drainage boards, drainage nets, geogrids, flexible permeable pipes, plastic blind drains and siphonic drainage systems.
Can geomembrane thickness, width, color and raw material be customized?
Yes. Raw materials, product specifications and dimensions can be customized. Geomembranes are available in black, green, blue and two-tone versions. Share your project specification and we will match the grade, thickness and roll size.
Which geomembrane should I choose for a landfill versus an aquaculture pond?
Landfills and mining heap leach pads typically use HDPE geomembrane, often textured on slopes, combined with a non-woven geotextile protection layer. Fish and shrimp ponds commonly use thinner smooth HDPE or LDPE liners. Final selection should follow the design engineer's specification.
Do you export directly to overseas buyers?
Yes. Changhong is a large-scale manufacturer with self-operated import and export rights, supplying contractors, distributors and project owners factory-direct from our plant in Taian, Shandong, China.
How can I get technical data sheets and a product catalog?
Use the Request a Catalog page or contact our sales team by email at [email protected] or by phone at +86 151 6383 0677 to receive catalogs and technical data sheets.
What quality assurance protocols verify stress-crack resistance and tensile strength?
Every production batch undergoes continuous mechanical and chemical analysis in our on-site laboratory. Testing covers Melt Flow Index (MFI), Carbon Black Dispersion (ASTM D5596), Oxidative Induction Time (OIT ASTM D3895), and Single-Point Notched Constant Tensile Load (SP-NCTL ASTM D5397). Certified batch inspection logs are provided prior to export dispatch.
How do container stuffing protocols protect rolls during deep-sea shipping?
Rolls are wrapped in protective non-woven geotextile covers with high-strength synthetic end slings, keeping them safe during container stuffing and port handling. Diameters and lengths are selected to maximize 40ft High Cube container volume without crushing interior cores.
