TrenchFormer-XHD Product Data
XHD 8″, 12″, 18″ advanced grate design is not only attractive, but it also provides strength and performance. XHD grates provide the largest inflow area available in cast grates for 8″,12″,18″ trenches, while still far exceeding all FAA load ratings.
XHD’s patented system utilizes two removable stainless steel pins plus two fixed pins for every two grates providing both longitudinal and vertical grate retention. An average of only one pin must be removed per grate for easy construction and trench maintenance. Additionally, this system eliminates concrete cracking from constrained thermal expansion and contraction that is often found in rigid four-bolt systems.
XHD does not utilize dissimilar materials (plastic, fiberglass, etc.) between the rails and concrete thus avoiding the potential for failure due to thermal expansion and contraction.
The system can be configured for the applications special flow and depth requirements. A large range of trench depths, slopes and configurations provides the Engineer with greater flexibility for challenging projects. Additionally, the system is pre-engineered and factory fabricated reducing the potential for construction errors in the field.
