FRP Grating

FRP trench covers are used over drainage channels, cable trenches and corrosive access areas where removable, anti-slip and rust-resistant panels are required. RFQs should confirm [clear opening, support ledge, span](https://qymetaltech.com/frp-trench-cover-frame-support-ledge-rfq/), load condition, thickness, resin environment and panel layout.

Quotation details to confirm





**Trench opening**



**Thickness and span**

### FRP trench covers: standard specifications

| Item | Common options | Notes |
|---|---|---|
| Thickness | 25, 30, 38 or 50 mm | Chosen from clear span and pedestrian or maintenance load. |
| Mesh | 38 × 38 mm or 50 × 50 mm; covered (solid) top on request | Open mesh drains quickly; covered top keeps debris out. |
| Cover width | Trench width plus bearing on both ledges | Measure the clear trench width and ledge width on site. |
| Section length | Typically 500–1000 mm | Short sections stay light enough to lift by hand. |
| Frame | None, FRP angle, SS304 angle or hot-dip galvanized steel angle | Existing frames can be matched from site dimensions. |
| Details | Lifting holes, cutouts, panel numbers | Numbered to the trench layout for installation. |
| Load class | Pedestrian or maintenance load by span | Vehicle load classes such as EN 124 are stated only with a test report. |













Product overview

## FRP trench covers for drainage and corrosive service areas

Use FRP trench covers when drainage or cable trenches need removable panels that resist corrosion and provide a safer anti-slip walking surface.

QY Metal Tech reviews clear opening, support ledge, load condition, resin exposure, cutouts and panel numbering before quotation so the supplied covers match the site sequence.

 



### FRP trench cover specification path

 

| Trench opening | Clear opening, support ledge width and cover bearing direction should be taken from site dimensions. |
|---|---|
| Thickness and span | Panel thickness is selected by support span, pedestrian or maintenance load and handling method. |
| Resin environment | State wastewater, chemical, outdoor UV, marine or washdown exposure before resin selection. |
| Surface | Gritted or molded anti-slip top surface is preferred for wet walking areas. |
| Panel layout | Confirm removable sections, lifting holes, cutouts, numbering and labels from drawings. |

 

 





Standards reference

## Resin, surface and panel layout should follow the service environment

- FRP trench covers should be reviewed by clear opening, support ledge, panel thickness, resin system, anti-slip top surface and removable-panel layout.
- Match each test reference to the property requested: [ASTM E84](https://store.astm.org/standards/e84/) addresses surface flame spread and smoke development under specified exposure conditions; [ASTM D635](https://store.astm.org/standards/d635) addresses the burning rate or extent and time of burning of horizontally positioned plastic specimens.
- [ASTM D2583](https://store.astm.org/standards/d2583) addresses Barcol indentation hardness. A hardness result does not establish a fire classification or the load capacity of a trench cover.
- These are method references, not QY product test results. For a requested report, identify its method and edition, specimen and reported results, then check their relationship to the supplied panel and project requirement.
- Outdoor, wastewater and chemical trench areas should confirm UV exposure, liquid contact, cleaning method and expected pedestrian or maintenance load.
- Final approval should follow trench drawings, panel numbers, cutout notes, lifting details, packing marks and buyer inspection requirements.

 



Specification examples

## Common FRP trench cover RFQ expressions

 

| 38 mm trench cover | Common FRP cover thickness example for drainage or cable trench panels. |
|---|---|
| Gritted removable cover | Anti-slip top surface and removable support ledge layout confirmed by drawing. |
| Custom trench width | Clear opening, cover width and support span reviewed from site dimensions. |
| Numbered panel set | Panel marks, lifting holes and packing sequence arranged by trench layout. |

Use these expressions as RFQ shorthand, then confirm clear opening, support span, resin type, surface, cutouts, panel marks and quantity before production.

 

 

 

 



Applications

## FRP trench cover applications and project references

These references help buyers connect FRP trench cover specifications with real drainage channels, removable access panels, anti-slip surface requirements and installation sequence.







### Drainage trench covers

Removable FRP covers protect wet, chemical and wastewater trench channels.









### Replacement panel sets

Site photos and old panel dimensions help match support ledges and cover sequence.









### Outdoor anti-slip covers

Gritted or molded top surfaces support safer walking in outdoor drainage areas.

FAQ

## FRP Trench Covers buyer questions

 

What are FRP trench covers used for?

Drainage channels, cable trenches, wastewater trenches and chemical plant access areas where corrosion resistance and removable access are needed.



How thick should FRP trench covers be?

38 mm is a common thickness example; the final thickness follows support span, pedestrian or maintenance load and handling method.



Can the covers be removable with lifting holes?

Yes. Covers can be supplied as removable sections with lifting holes, cutouts, labels and panel numbers.



Are FRP trench covers suitable for chemical or outdoor areas?

Yes, when the resin is matched to the liquid contact, UV exposure and cleaning method. State these conditions in your RFQ.



Which top surface should I choose?

A gritted or molded anti-slip surface is preferred for wet walking areas over drainage trenches.



Can you match replacement covers for an existing trench?

Yes. Send site photos and the old cover and ledge dimensions so the new covers fit the existing support ledge and sequence.
