In the use of FRP grating in industrial and infrastructure areas, questions often arise regarding the difference between molded grating and pultruded grating. Both use Fiberglass Reinforced Plastic (FRP) material, but they have different characteristics and functions. Understanding these differences helps determine the type of grating that is most suitable for site conditions.
PT Orindo Eratec provides various FRP grating solutions for project needs with diverse specifications.
Molded Grating
Molded grating is a type of FRP grating produced through a molding process. This process creates a panel structure with relatively uniform bidirectional strength. Due to its structure, molded grating is known for its excellent resistance to corrosion and chemical exposure.
This type of grating is commonly used in humid or aggressive environments, such as wastewater treatment areas, chemical plants, and drainage systems. Molded grating surfaces are usually equipped with anti-slip textures, making them safe for use in wet areas.
Pultruded Grating
Pultruded grating is made from FRP bars produced through a pultrusion process, then assembled into grating panels. The main characteristic of pultruded grating lies in its higher load-bearing strength in one particular direction.
Pultruded grating is suitable for areas with longer support spans and higher load requirements, such as industrial platforms, walkways, and operational areas with intensive traffic. The appearance of pultruded grating also tends to be more precise and neat.
Differences Between Molded Grating and Pultruded Grating
The main difference between molded grating and pultruded grating lies in the production method and strength characteristics. Molded grating excels in resistance to corrosive environments with strength distributed in two directions, while pultruded grating is superior in supporting heavier loads over longer spans.
The selection of grating type should be adjusted to usage conditions, including the working environment, load capacity, and structural design.

Dalam penggunaan grating FRP di area industri dan infrastruktur, sering muncul pertanyaan mengenai perbedaan molded grating vs pultruded grating. Keduanya sama-sama menggunakan material Fiberglass Reinforced Plastic (FRP), namun memiliki karakteristik dan fungsi yang berbeda. Memahami perbedaan ini membantu menentukan jenis grating yang paling sesuai dengan kondisi lapangan.
PT Orindo Eratec menyediakan berbagai solusi FRP grating untuk kebutuhan proyek dengan spesifikasi yang beragam.
Molded Grating
Molded grating merupakan jenis grating FRP yang diproduksi melalui proses pencetakan. Proses ini menghasilkan struktur panel dengan kekuatan dua arah yang relatif merata. Karena strukturnya, molded grating dikenal memiliki ketahanan yang sangat baik terhadap korosi dan paparan bahan kimia.
Jenis grating ini umumnya digunakan di lingkungan yang lembap atau agresif, seperti area pengolahan limbah, pabrik kimia, dan sistem drainase. Permukaan molded grating biasanya dilengkapi tekstur anti slip sehingga aman digunakan di area basah.
Pultruded Grating
Pultruded grating dibuat dari batang FRP yang diproduksi melalui proses pultrusion, kemudian dirangkai membentuk panel grating. Karakter utama pultruded grating terletak pada kekuatan beban yang lebih tinggi pada satu arah tertentu.
Pultruded grating cocok digunakan pada area dengan bentang penopang lebih panjang dan kebutuhan beban yang lebih besar, seperti platform industri, walkway, dan area operasional dengan lalu lintas intensif. Tampilan pultruded grating juga cenderung lebih presisi dan rapi.
Perbedaan Molded Grating dan Pultruded Grating
Perbedaan utama antara molded grating dan pultruded grating terletak pada metode produksi dan karakter kekuatannya. Molded grating unggul dalam ketahanan terhadap lingkungan korosif dengan kekuatan yang menyebar ke dua arah, sedangkan pultruded grating lebih unggul dalam menopang beban berat dengan bentang yang lebih panjang.
Pemilihan jenis grating sebaiknya disesuaikan dengan kondisi penggunaan, baik dari segi lingkungan kerja, kapasitas beban, maupun desain struktur.
