Technical resource

Use this overview to choose FRP grating type,   
resin direction, thickness, mesh and surface,   
before requesting a quote.

 **Start with four decisions**

- Application environment
- Resin and corrosion
- Surface and slip risk
- Span, load and cut size

 

 







## Choose FRP grating by application first

FRP grating selection should start from the jobsite condition, then move into resin, thickness, mesh, span and surface. Use this matrix to decide which product page or technical note should be opened next.





**Choose the right product page**Pick molded, trench, car wash or tree grate path.



**Prepare RFQ details**Collect span, size, load, surface, resin and quantity.



**Check technical risks**Open resin or anti-slip notes when risk is unclear.



**Shorten quote review**Give purchasing and engineering a cleaner checklist.

 



 

| Wet platforms and walkways | **[Molded FRP Grating](https://qymetaltech.com/molded-frp-grating/)**Start with panel thickness, mesh size, clear span and pedestrian load. Concave or gritted surface can be reviewed after the walking condition is clear.**Typical starting point**25 / 30 / 38 mm; 38 x 38 mm mesh; span and deflection by load review. | **Send for RFQ**Panel size, support span, quantity, surface preference and fixing method. |
|---|---|---|
| Chemical or wastewater floors | **[Resin & Corrosion Notes](https://qymetaltech.com/resources/frp-resin-corrosion-notes/)**Confirm chemical name, concentration, temperature and cleaning cycle before fixing resin direction.**Typical starting point**30 / 38 mm; resin by exposure; gritted surface for wet chemical rooms. | **Send for RFQ**Exposure details, wet or splash condition, panel thickness and expected traffic. |
| Drainage trenches and cable trenches | **[FRP Trench Covers](https://qymetaltech.com/frp-trench-covers/)**Focus on clear opening, support ledge, load condition, removable panels and edge treatment.**Typical starting point**38 mm for many pedestrian covers; 50 mm or engineered review for wider/heavier spans. | **Send for RFQ**Trench width, span, drawing, load type, surface and panel length. |
| Car wash and washdown bays | **[Car Wash FRP Grating](https://qymetaltech.com/car-wash-frp-grating/)**Review detergent exposure, drainage, gritted surface and frequent cleaning requirements.**Typical starting point**38 mm gritted FRP; 38 x 38 mm mesh; resin and clips by bay layout. | **Send for RFQ**Bay layout, drainage width, cleaning chemicals, traffic and color requirement. |
| Tree pits and landscape drainage | **[FRP Tree Grates](https://qymetaltech.com/frp-tree-grates/)**Check custom shape, tree opening, split panels, UV exposure, color and pedestrian load.**Typical starting point**25 / 38 mm by load and frame; cutouts, split panels and color by drawing. | **Send for RFQ**Opening drawing, tree hole diameter, panel shape, color and quantity. |

## FRP product paths by use case

The four cards below make this page work as a buyer path, not only a reading page. Open the product page when the application is already clear; open the technical notes when resin or surface is uncertain.
