Product Description

The thrie beam highway guardrail (also named as tri-beam crash barrier or tri-wave guardrail etc.) is a type of guardrail that is mainly installed along the highways around the world.
Wuhan Dachu Thrie Beam Highway Guardrail crash barrier is formed in accordance with the latest highway safety barrier technology to make sure its high durability and maximum strength. Dachu road guardrail components are made of high quality steel (Q235, Q345, A36 etc.), which can effectively reduce the impact force caused by vehicles to the maximum extent. Dachu Thrie Beam crash barrier is a perfect combination of high quality material (Q235B, Q345B, etc.) and excellent anti-rust zinc or powder coating.

Thrie Beam Guardrail Features
1. Safety: the thrie beam highway guardrail is mostly installed on the roadside where there is danger and cars with high speed, to keep the vehicles on the right track and the things or animals from going into the road, thus ensuring road safety.
2. High strength: anti-corrosion thrie beam highway guardrail is made of ASTM, EN, BS, AS/NZS, and JPS steel, they are of high strength with toughness.
3. Long lifespan: after cold rolled, the thrie beam highway guardrail will do hot dipped galvanization in the zinc pool with high temperature, which highly improves its antioxidant capacity and corrosion resistance.
4. Eco-friendly: The Q235/Q345 steel, the material of thrie beam highway guardrail, is recyclable and reusable. It can be used to make other metallic products by recycling.
5. Easy installation and repair: Easy installation, repair and replacement: Modular design can be used with many kinds of crash barrier system; It can be repaired quickly after accident as well. It's simply assembled by bolts and nuts, easy to install and change the guardrail spare parts.
6. Cost-effective: compare with the other crash barrier (roller barrier, plastic barrier and so on), the powder-coated steel highway guardrail is of lower price and longer life.
7. Beautiful color: we can do powder spray with different colors on the thrie beam highway guardrail, make it more beautiful and suitable with the road sight.

Our Production Process: 

Guardrail Installation Criteria:
Please observe the following guidelines to install barrier. Our company will send the techincians and reprentative for our product guardrails instllation for all the Techincal Support and Guiance.

Preliminary operations
Where installation is to be carried out in traffic, all necessary road signs must be set up in order to direct traffic and protect workers from vehicles, in accordance with safety regulations. The parts making up the road barrier can be unloaded from the transport vehicles by means of a crane fitted to the vehicle, or forklift truck, in accordance with current safety regulations. Workers must be supplied with all required equipment, including safety shoes, gloves and goggles and -where necessary - helmets, safety harnesses and all else specifically needed for the site and required by current safety regulations.

Installation sequence
The assembly diagram provides instructions for correct barrier installation. Fully and completely follow these instructions.
Main steps:
1.  Trace out a full line of reference on the ground, which will serve to align poles and beams.
2.  Place the beams along the traced line taking into account the direction of traffic.
3.  Posts (designated posts according to the drawings) are to be lifted vertically and planted in the
4.  ground1,080 mm (or designated) deep the holes in the top and spaced 2,000mm or 4,000mm apart. A pile-driver is generally used. During this phase, please check: alignment and level of posts, distance between posts, that they are vertical, and distance from the embankment, all in accordance with the measurements and tolerances specified in the applicable drawing of reference.
5.  Assemble the spacers to the uprights using the M16x50 mm bolts;
6.  Assemble the beams that have been laid on the ground, attaching them to the spacers with M16x45 bolts and the beam themselves by means of bolts M16x35 supplied.
7.  Use the calibrated pneumatic screwdrivers to fasten all nuts and bolts into place, checking levels and alignments.
8.  Installation must always take place under the surveillance of a specialist technician, and in full compliance with the final drawing and current safety regulations.

Inspection of installation conformity
The technician responsible for the installation shall, at the very least, control conformity of the following, prior to beginning assembly, during work and upon conclusion, by using all measurement instruments necessary and in his possession:
1.  Full compliance of the installation with the final drawings of reference.
2.  Pole spacing and height of upper beam and current edge in accordance with that specified on the final drawings of the barrier, dilation joints and ends.
3.  Length and alignment of the installation on the basis of the final drawings and the road layout and altimetry.
4.  Final coupling bolt torque according to that set in the assembly diagram.
5.  Compliance with all applicable safety regulations.
