Wire Rope Safety Barrier (WRSB), or also terms as Cable Barrier, Safety Fence, Cable Guardrail, can all refer to the same type of road safety barrier.
One WRSB can be categorized based on properties described in the table below:

	Tension (Low/High)	Containment/Deflection	No. of ropes (1/2/3/4)	Standards - TL3/TL4/other	Symmetrical/Non-Symmetrical
example WRSB 1	High	Deflection	4	other	Symmetrical
example WRSB 2	High	Containment	4	TL4	Symmetrical

Tension - High tensioned WRSB are generally tensioned to app. 2.5t during installation (subject to weather conditions, type of WRSB, and other factors). Low tensioned WRSB are not as common as they used to be, the tension is generally very low and close to 0.

Containment or Deflection - based WRSB. Deflection aimed WRSB could be tensioned to slightly higher tension and will most probably use 4 wires (ropes). The overall length of the barrier tends to be shorter. Containment based WRSB will have wire ropes spread further apart from each other (approximately 150mm - 60mm), to increase the catchment area.

Number of ropes -
