What HDPE and Fiberglass systems hideConcrete consolidation under the rail is vital to the longevity of any system in service under heavy loading. Fiberglass and HDPE linear systems can hide construction defects, which can cause costly downtime and ultimately complete system failure.
XHD – Extreme Heavy Duty
Airports and Ports
XHD’s galvanized steel rails provide concrete bearing width that is the widest in the industry. Also, XHD systems do not create additional failure liability between the rail and concrete by introducing a dissimilar material such as HDPE or fiberglass, that have low compressive strength, creep, or thermal expansion properties. In addition, XHD systems utilize removable pins for grate retention, thus eliminating the tensile stress created by constrained thermal expansion in rigid four bolt systems.
