X-Tension Guardrail End Treatment

GSI is the exclusive Texas Distributor of the X-Tension Guardrail End Treatment from Barrier Systems, Inc., the only fully re-directive, non-gating guardrail end terminal on the market.

Rather than using compression based technology, the X-Tension is designed to absorb the energy of the impacting vehicle at the impact head rather than being transferred down the rail, providing added vehicle control and greater energy absorbing capabilities.

The system is designed to be used interchangeably between tangent and flared applications, resulting in significant savings in repair, inventory, and maintenance costs.

The X-Tension has full TxDOT approval for NCHRP 350 TL-3 applications.

GSI also is a distributor of the X-LITE End Teatment from Barrier Systems, Inc.
