Thrie Beam Guardrail

thrie beam guardrail

The thrie beam guardrail is also called three waves guardrail, it is one of the most commonly used corrugated highway guardrail types.  Compared with w beam guardrail, the thrie beam guardrail is stronger in terms of anti-collision performance.

RANHUA Thrie Beam Guard Rail Advantages:

  1. The structure is very simple so it is very easy to install, uninstall, and repair.
  2.  The galvanized surface won’t go rust so that a very long service life can be guaranteed.
  3. The thrie beam guardrail can be used in a wide application range.
  4. Less maintenance and zero maintenance cost to save your labor.
  5. Good anti-corrosion resistance.

The Difference Between W Beam Guardrail and Thrie Beam Guardrail

First of all, there is no single wave guardrail on the market.

The main difference lies in the guardrail rail specification and post specification.

Overall specification

The specification for w beam highway guardrail is 4320mm * 310mm * 85mm * 3/4.

The specification for the thrie beam highway guardrail is 4320mm * 506mm * 85mm * 3/4.

Guardrail post specification

The specification of the w beam guardrail post is 114/ Ø140 mm × 4.5mm × height.

The specification of the thrie beam guardrail post is 114/ Ø 140 mm × 4.5mm × height.

Weight difference

The weight of 1km w beam guardrail with 3mm and 4mm thickness is 12.3ton and 16.388ton.

The weight of 1km thrie beam guardrail with 4mm thickness is 12.3ton and 25.5ton.

Post shape difference

The w beam guardrail is always equipped with round shape post while the thrie beam guardrail is equipped with square shape post.

Strength grade difference

Relatively speaking, the anti-collision level of the w beam guardrail is weaker than the thrie beam guardrail.

Application difference

In terms of application, the w beam guardrail is widely used for the rural and suburban road, while the thrie beam guardrail is in the highway or mountain road, where the road condition is much dangerous.

Price difference

In terms of price, the w beam guardrail is lower than the thrie beam type for obvious reason.

Despite the differences they have, they share one same thing which is that the height of each wave for both is 85mm.
