Combining corrosion resistance, long life, and a low maintenance design, CQDJ grating is superior to conventional metallic gratings. This advanced grating is manufactured with a recessed tie bar configuration and is lightweight and easy to fabricate. Savings on labor and equipment often make the total installed cost of CQDJ grating comparable to that of steel. This advanced pultruded grating is designed for use in a wide range of industrial applications that require strength and corrosion resistance. Manufactured with a high percentage of glass within the laminate, pultruded grating provides durability, extremely high unidirectional strength, and stiffness. Due to its exceptional stiffness, it can be used with confidence where wide support spans are required. For most applications where it is used to replace steel grating, CQDJ industrial grating rarely requires additional support. Combining its low cost of installation with low maintenance and long life, CQDJ offers a life cycle cost that is significantly lower than that of its metal counterpart.
