Product Overview

Huangang pultruded hollow FRP walkway panel is hollow cross-section fiberglass structural grating integrating walkway decking and trench cover dual functions, produced in Henan, China adopting continuous pultrusion integrated molding technology. Raw material adopts high-strength E-glass fiber fully impregnated with composite resin system including butyl ester, isophthalic polyester, vinyl ester and polyurethane resin, forming compact hollow internal structure with uniform fiber distribution, greatly boosting bending load bearing capacity while keeping lightweight. The outer surface is treated into seamless smooth finish, optional anti-slip textured surface upon request, multiple solid color options customizable to match factory environment layout, standard 500mm width ready for shipment, length, wave shape and overall profile fully adjustable per project drawings. Our factory provides full one-stop deep machining: mold opening for special cross-section shapes, fixed-length precision cutting, edge bending forming and bolt hole punching, delivering finished panels directly usable on site without secondary processing. The multi-resin composite formula delivers permanent anti-corrosion performance against acid, alkali, industrial waste water, hydrogen sulfide and coastal salt fog, never rust, rot or crack like metal and concrete grating. Dual functional design allows installation as pedestrian walkway tread on factory platforms, chemical workshop access decks, offshore aquaculture walkways; meanwhile it serves as anti-odor sealing cover for sewage trenches, drainage ditches and biochemical pools, extensively used in chemical industry, municipal environmental engineering, electroplating factories, food processing plants and marine industrial projects.

Core Product Advantages

1. Continuous Pultrusion Hollow Reinforced Fiber Structure

   Unidirectional E-glass roving evenly distributed inside hollow profile, no internal delamination, stable high bearing capacity under long-term pedestrian load, not easy to deform or break.

2. Multi-Type Anti-Corrosion Composite Resin Formula

   Optional resin grades for different corrosive environments: polyester for general factory, vinyl ester for heavy chemical waste gas, polyurethane for high humidity coastal zones, meet all industrial anti-corrosion demands.

3. Full Customization of Color, Length & Profile Shape

   Custom-tune any solid color, arbitrary production length, develop exclusive cross-section molds for special walkway and ditch span sizes, perfectly match various construction design requirements.

4. Complete One-Stop Multi-Process Machining Support

   In-house workshop completes custom mold development, fixed-size cutting, edge bending and assembly hole punching, eliminate outsourcing processing and shorten construction cycle.

5. Lightweight High Strength for Easy Transportation & Installation

   Only 1/4 weight of steel grating with equivalent load capacity, easy manual lifting and laying without heavy hoisting equipment, reduce labor and logistics cost.

6. Dual-Purpose Walkway & Trench Cover Integrated Design

   Single product realizes two application scenarios: anti-slip walk deck for workshop platforms, sealed anti-odor cover for sewage ditches, save separate procurement cost for two different materials.

7. Smooth Easy-Clean Surface with Optional Anti-Slip Treatment

   Seamless smooth surface resists sludge and chemical scale adhesion, quick water flushing maintenance; customized grit anti-slip layer available for wet workshop and marine walkways to prevent slipping hazards.

8. Wide Universal Industrial & Municipal Compatibility

   Suitable for chemical plant anti-corrosion platform walkway, municipal sewage treatment ditch cover, electroplating workshop waste water trench panel, seafood farming aquaculture deck, food factory clean room walk tread and all industrial drainage supporting projects.

Wide Application Scope
