Guangtuo is a composite-material manufacturer based in Hebei, China, focused on fiberglass (FRP/GRP) water-storage systems — SMC sectional panel tanks, one-piece cisterns, cylindrical tanks, chemical/effluent tanks and fire-fighting tanks.

Our design centers on potable-water safety: a smooth, non-leaching gel-coat interior and modular bolted assembly that never rusts or contaminates stored water.

Standards We Reference

• ANSI/AWWA D120-19 (R2025) — thermosetting FRP tanks for water service
• BS EN 13280:2001 — GRP one-piece & sectional above-ground cold-water cisterns
• GB/T 17219-2025 — hygienic safety evaluation for drinking-water contact
• ASTM D3299 / D4097 — filament-wound / contact-molded chemical tanks

We list frameworks referenced; approvals actually held are stated separately once verified. Note: ISO 28765 covers enameled steel tanks, not ours.
