Product Overview

Huangang anti-slip SMC FRP drain grate is slotted drainage cover matched with integral frame, specially developed for municipal road rainwater and sewage drainage interception, produced in Henan, China adopting mature SMC sheet molding compound hot press integrated molding technology. Long-strand fiberglass roving mixed with anti-aging thermosetting resin is pressed into solid one-piece grate body with internal reinforced ribs, greatly improving compression and impact resistance to bear long-term pedestrian and light vehicle rolling without cracking or deformation. The top surface adopts parallel long strip slotted drainage design with raised anti-slip edges on each strip, which can quickly drain rainwater while increasing friction to prevent slipping in rainy weather. The supporting frame is integrally molded with anti-drop limit structure to avoid the grate tilting and falling off after long-term use. Standard 600 series specification ready for shipment, all custom dimensions and outlines available, black as standard color, grey, green and other decorative colors can be customized according to project standards. Our factory provides full custom processing solutions: exclusive mold opening for non-standard channel widths, precision punching for lifting holes, pipeline reserved holes and identification slots, no secondary cutting required on construction site. Different from cast iron drain grates, SMC fiberglass composite has no scrap recycling value to effectively solve theft problems, long-term resistant to acid-base sewage, underground soil corrosion and outdoor UV aging, lightweight for easy manual lifting and no metal collision noise when vehicles pass. This FRP drain grate is standard supporting drainage facility for urban municipal road sidewalks, residential community rainwater ditches, chemical factory workshop sewage channels, park pedestrian walkways and all municipal road maintenance construction projects.

Core Product Advantages

1. SMC High-Pressure Reinforced Integrated Molding Structure

   Cross-layer long fiberglass layout plus built-in reinforcing ribs, stable heavy load performance suitable for sidewalks and light traffic auxiliary roads, long service life without breakage under daily rolling pressure.

2. Slotted Anti-Slip Fast Drainage Dual Design

   Long strip through drainage holes realize rapid rainwater discharge to prevent road water accumulation; raised anti-slip borders on each strip increase friction coefficient, eliminate pedestrian slipping risks in rainy days, meet municipal road safety standards.

3. Complete Matching Integral Anti-Drop Frame

   Supporting frame with limit anti-drop buckle structure, fix the grate firmly to avoid displacement, tilting and hidden safety hazards caused by vehicle rolling impact.

4. Full Custom Size, Outline & Color Matching

   Support custom rectangular, square outlines, arbitrary customized length and width based on drainage ditch span; black standard road color plus custom decorative colors for scenic spots, campuses and industrial parks.

5. Complete Custom Mold Opening & Precision Punching Machining

   Develop exclusive molds for non-standard channel sizes, punch lifting handle holes, identification marking holes and pipeline through holes according to engineering drawings, deliver finished grate and frame set ready for direct installation.

6. Natural Anti-Theft FRP Composite Material

   SMC fiberglass has no metal recycling value, completely solve the frequent theft of cast iron drainage grates, reduce regular replacement maintenance costs for municipal management departments.

7. Permanent Sewage & Soil Anti-Corrosion & UV Resistance

   Resist long-term immersion of acid-base sewage, underground corrosive soil and outdoor ultraviolet aging, no rust, peeling or decay defects of metal drainage covers.

8. Lightweight Silent & Easy Daily Maintenance

   Only 1/3 weight of equivalent cast iron drain grate, single worker can lift and clean the blocked sludge; no metal clanging collision noise when vehicles pass, reduce urban road noise pollution.
