- Maintenance is another significant benefit of choosing fiberglass stair treads
- Sewage treatment is an intricate process that involves the removal of contaminants from wastewater, primarily from domestic and industrial sources. It is a critical step in safeguarding public health and preserving water resources. Fiberglass plays a pivotal role in this process due to its exceptional properties. It is corrosion-resistant, lightweight, strong, and has a long lifespan, making it ideal for withstanding the harsh conditions prevalent in sewage treatment facilities.
Gratings & Covers
- Despite their numerous advantages, PDC drill bits also present challenges. They can be more susceptible to damage from impacts or excessive torque, necessitating careful operation and maintenance. However, ongoing research and development continue to address these issues, pushing the boundaries of PDC drill bit performance.
Pultruded Grating and Molded Grating are two common types of grating used in various industrial applications. Here is a comparison between them:

FRP Grating is manufactured using an Isophthalic Polyester which has very good chemical resistance, good flame resistance and is the best general-purpose resin available. (Other resins available are Vinyl Ester and Phenolic, available for custom orders)
FRP Pultruded Grating adalah jenis grating yang dibuat melalui proses assembling produk yang dihasilkan dari produk mesin pultrusi, di mana serat fiber, resin, pigmen dan zat aditif lainnya dicampur dalam sebuah bak kemudian ditarik melalui cetakan untuk membentuk profil yang kuat dan kaku. Material ini menawarkan kekuatan tinggi, stabilitas dimensional, dan ketahanan terhadap korosi serta kondisi lingkungan yang keras. Desainnya yang kokoh dan presisi menjadikan FRP Pultruded Grating sebagai pilihan unggul untuk aplikasi industri yang membutuhkan durabilitas dan performa tinggi.

Unlike competitions products that have a framework sitting on top of the flume, Openchannelflow's recessed grating option doesn't present a trip hazard.


Available in 1” deep, 1” x 4” pattern, rectangular mesh FRP gratings are commonly used for walkways and trench applications. When selecting rectangular mesh grating it is important to specify the span (rectangular opening) of the grating perpendicular to the supporting structure.
