"When It Has To Work"

Custom Fabrication

RIBS (Rapidly Installed Breakwater System)

Our HydroRIB System was designed and manufactured for the U.S. Military to provide a portable, rapidly installable, wave attenuation system.  These large water filled cylindrical bladders (one million gallon capacity) are used to reduce wave action for lightering operations.  The System is designed for transport to the operation location for deployment and installation creating a barrier to absorb wave action.

PACK (Portable Air Cushion Kit)

The PACK System was designed and manufactured for military conversion of standard barge modules into large platform air cushion vessels for heavy equipment transport during amphibious military operations.

Large Format Building Wrap Banners

The images for these large signs are printed in sections and carefully matched, assembled, reinforced with a selection of finishing procedures and installed by the customer on major structures nationwide. You have probably seen our work in New York City, Miami, Chicago, Dallas, Los Angeles and many other major cities.
