Guangtuo is a composite-material manufacturer based in Hebei, China, focused on filament-wound GRP/FRP pipe for water, sewage and industrial corrosive media. Our range covers pressure pipe, sewer pipe, sand-filled mortar pipe and vinyl-ester industrial pipe.

We design the wall — corrosion barrier, helical structural layers, optional quartz-sand core and outer UV layer — against your pressure, stiffness, burial and medium conditions, rather than shipping a generic catalog pipe.

Standards We Reference

• AWWA C950 — fiberglass pressure pipe (DN25–DN4000)
• ASTM D3517 — fiberglass pressure pipe; ASTM D3754 — sewer & industrial pressure pipe
• GB/T 21238 — FRPM mortar pipes; ISO 14692 — GRP piping for oil & gas

We list frameworks referenced; approvals actually held are stated separately once verified. Certificates held: 【to be filled — do not list unless held】.
