Global Delivery

Standard manufacturers can't meet your project timeline. We maintain stock for standard products and commit to on-schedule custom orders.

Poor quality control leads to leaks and failures. Our CNAS-certified lab tests every batch with full documentation — from raw materials to finished products.

Off-the-shelf products don't match your unique requirements. We provide on-demand design — from standard specs to fully custom non-standard solutions.

You receive products but no guidance. Our experienced engineering team offers full technical support from selection to installation, ensuring a smooth project.

Industrial FRP procurement comes with hidden risks. We've helped hundreds of clients avoid them

Common Challenges

Our Solutions

From standard storage tanks to fully custom systems — designed and manufactured under one roof.

Vertical & horizontal configurations for chemical storage, water treatment, and food-grade applications. Leak-free design, 20+ year service life.

Massive capacity up to thousands of cubic meters. On-site winding available. Ideal for chemical plants, power stations & water treatment facilities.

Filament-wound pipes DN200 to DN4000. Corrosion-resistant, 50-year design life. For chemical transport, wastewater, seawater & industrial fluid handling.

Complete range of elbows, tees, flanges, reducers & manholes. Hand lay-up & compression molding with non-standard customization and bulk delivery available.

Angles, channels, I-beams, tubes & custom shapes. High strength-to-weight ratio, corrosion & UV resistant — ideal for structural, walkway & handrail applications.

Pipe fittings, pultruded profiles, gratings, tower equipment & more. Tailored to your drawings and specs — no minimum order for custom projects.

Every industry has unique challenges. We understand yours

Acid & alkali resistant FRP tanks & pipes. Reliable replacement for rubber-lined steel — proven leak-free performance.

Lightweight, corrosion-proof FRP solutions for municipal & industrial wastewater. Lower lifecycle cost vs traditional materials.

Heat & arc resistant FRP for power plants. Safe operation in high-temperature environments with excellent electrical insulation.

Salt spray resistant FRP for harsh marine environments. Ideal for offshore platforms, coastal facilities & seawater systems.

FRP grating platforms, handrails, stair treads & daylighting panels. Lightweight yet high-strength, completely maintenance-free with a service life exceeding 30 years.

Slurry transport pipelines, electrolytic cells & pickling tanks. Superior wear and corrosion resistance, significantly reducing unplanned downtime and replacement frequency.
