Trench drain grates, also known as drain tops, channel grates, or trench screens, are components designed to cover and protect water drainage systems or trench drains. Trench drains are linear channels that collect and redirect surface water. This helps in preventing flooding and erosion of low-landscaped areas. Grates also serve as a protective layer over these channels, allowing water to flow through while preventing the entry of large debris, trash, and other unwanted materials that could clog outlet pipes.

Product features
Corrosion-Resistant
Because they are manufactured from fiberglass reinforced plastic (FRP), these trench grates are built to withstand even the harshest conditions. In fact, unlike metal grates, which rust and deteriorate when exposed to moisture, saltwater, or chemicals, fiberglass grates remain unaffected. This makes them ideal for coastal areas, chemical facilities, and anywhere regular exposure to water or industrial substances is a concern.
Non-Conductive
Because fiberglass is non-conductive, it provides a safe solution in environments where electrical hazards may be present. This is especially important for industrial and municipal sites where drainage grates are placed near electrical components or wiring.
Fire-Retardant
Fiberglass grating is also known for having fire-retardant properties. The resin and fiberglass composition in these grates are specifically designed to comply with fire safety standards, providing an added layer of protection in applications prone to fire risks.
Non-Skid
Safety is a priority in any drainage application, and fiberglass trench grates deliver with their built-in slip-resistant surfaces. The textured finish minimizes the risk of slips and falls, making them suitable for areas with heavy pedestrian traffic or extremely wet conditions, such as food and beverage processing plants.
Lightweight and Easy to Handle
Since fiberglass grating is significantly lighter than steel or cast iron alternatives, it can be installed quickly and with less labor, saving time and reducing costs. Even in projects with limited equipment or access, fiberglass trench grates can be installed quickly without compromising on quality.
Low Maintenance Requirements
Due to their durable, non-reactive nature, fiberglass grates require minimal maintenance. There is no need for frequent replacements or protective coatings, resulting in lower overall costs and fewer headaches for property owners and facility managers.
Common Uses
Manufacturing & Industrial Facilities
Trench drain grates are widely used in industrial settings to help manage the flow of water, chemicals, and other liquids. In manufacturing plants, warehouses, and factories, these grates play a pivotal role in maintaining a safe and clean working environment. They prevent the accumulation of hazardous liquids, reducing the risk of slips and falls.
Commercial Spaces
Shopping malls, parking lots, and other commercial areas benefit from trench drain grates by efficiently managing stormwater runoff. These grates work in tandem with channel drains to ensure that rainwater is directed away from pedestrian and vehicular traffic areas, preventing potential accidents and maintaining a visually appealing space.
Residential Applications
In residential settings, drain grates find utility in areas prone to water accumulation, such as driveways, patios, and swimming pool decks. They enhance the appeal and overall safety of these spaces by preventing stagnant water, which over time often leads to slippery surfaces, disease, and structural damage.
Public Spaces
Parks, pedestrian walkways, and public areas also incorporate trench drain grates to create a safer and more aesthetically pleasing environment. By efficiently managing water runoff, these grates contribute to the longevity of infrastructure and reduce the risk of accidents caused by standing water.

> Pattern plate
> Concave Surface (meniscus profile) - This is how the grating comes naturally out of the mold. The raised edges form a lip which offers slip resistance.
> Grit Surface - Excellent slip resistant surface
> Smooth Surface - Great for Wastewater Treatment plants or Architectural applications
Menyediakan 2 jenis proses kisi parit FRP, yaitu kisi parit fiberglass cetak dan kisi parit fiberglass pultruded. Anda dapat memilih proses yang tepat sesuai dengan kebutuhan proyek Anda.
Kisi-kisi Parit Fiberglass Cetakan
Kisi-kisi parit fiberglass yang dicetak dicetak secara integral dalam satu cetakan, sehingga tidak ada sambungan pada pertemuan kisi-kisi parit, yang membuat kisi-kisi parit fiberglass memiliki kekuatan yang seragam baik dalam arah memanjang maupun melintang, dan membuatnya cocok untuk aplikasi yang memerlukan kinerja Kelas Beban C atau Kelas yang lebih tinggi.
Parit Fiberglass Pultruded
Metode ini dibuat dengan menarik serat kaca dan resin secara terus-menerus melalui cetakan yang dipanaskan untuk membentuk batang bantalan berbentuk T atau I. Jarak antar batang yang lebih rapat akan meningkatkan kekuatan, semakin tinggi kekuatan kisi serat kaca yang dipultrusi, yang dapat meningkatkan kapasitas menahan beban kisi parit serat kaca untuk area bentang panjang atau area dengan lalu lintas tinggi.
