With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.

    Guardrail Transitions - Safety | Federal Highway road safety beam transitions

    To use the transitions tested to date, the concrete safety shape barrier must be transitioned to a vertical or flared back vertical wall. Transitioning from the concrete safety shape barrier to avertical wall should not be abrupt. A 10-foot transition (as shown in Figure 3C) is recommended.Highway Guardrail Transition Beam | ShiTeng Traffic road safety beam transitionsIn the daily use of anti-collision guardrails, the hot dipped galvanized guardrail transition beam is the most used for where there is w beam guardrail to thrie beam guardrail (or opposite). Hot dipped galvanized guardrail transition beam can be used for highway to country road, tunnel exit, bridge Guardrail Transitions - Safety | Federal Highway road safety beam transitionsThe Thrie Beam Transition to Modified Safety Shape (Figures 8A and 8B) features a modified receiver cast into a concrete safety shape barrier, along with modification to the standard safety shape configuration in order to accept the larger thrie beam end shoe. It has a bevel

These transitions have been tested or are deemed to comply with NCHRP (1993). The transitions are achieved through stiffening of the steel safety barrier by the use of special sections and connectors, reduced post spacing and nesting (i.e. two sections

    During head-on impacts, the SKT head slides over the W-beam guardrail. The rail is sequentially kinked or bent as it moves through the head. The kinked guardrail exits the head safely and the vehicle is brought to a controlled stop.
