Long the industry leader for covering systems, ATP expanded its product line several years ago with the acquisition of Keystone line of outlet gates. Committed to offering the same levels of service, support and engineering expertise for gates as we do on covering systems, we immediately began reviewing the existing Portloc gate models for areas which could be improved and subsequently introduced our now highly popular line of AEROgates.

Combining the best features of existing gates with improvements created as a result of our extensive field studies and conversations with loading and unloading facilities, AEROgates are available in a variety of sizes and materials to meet your gate needs.

We have also created WorXgates which were designed to serve as a cost effective way to update many of the older style manual lock weld on gates to an automatic locking version. WorXgates have indirectly extended the life of many older style hopper cars by eliminating costly downtime resulting from repeated repairs to manual locks destroyed by high torque automatic gate openers.

In addition to these new designs, we continue to support the older Keystone designs by providing replacement components for the Portloc III and IV series gates as well as continuing to manufacture Keystone gates for which no AEROgate or WorXgate replacement are yet available.
