W-Beam Popular Applications:
W-Beam in Parking Lot Interstates, Highways and Secondary Roads
W-beam highway guardrails are commonly installed on interstates, roadways, and secondary roads to protect run-off-road vehicles from natural and man-made roadside hazards
Parking Lots
W-Beam parking lot guardrails offers highly effective shielding in parking lots against vehicle hazards such as light poles, buildings, ditches, etc. Our guardrail end treatments are ideal for areas with a high concentration of pedestrian traffic
Bridges and embankments
W-Beam bridge and embankment guardrails provide a lifesaving shield from the areas below bridges (rivers, railroad tracks, other roads, etc.).
Parks and Recreation
Guardrails provide barriers to restricted park areas and protect wildlife, and can also be installed over cliffs and other potentially dangerous areas.
We manufacture highway guardrails according to those Standards as below:
A. JT/T 281-1995(Corrugated Sheet Steel Beams For Expressway Guardrail - China)
B. AASHTO-M180 (Corrugated Sheet Steel Beams For Highway Guardrail - USA)
C. AS/NZS 3845:1999(Road Safety Barrier Systems - Australia/New Zealand)
D. BS EN-1317(Road Restraint Systems - Europe)
E. RAL RG620 (Germany)
F. Or tailor-make according to client's requirements
Our Production Process:
Corrugated Guardrail Installation Steps:
Step 1. Site Preparation
Step 2. Driving the Posts
Step 3. Joining the W-Beam Guardrail Panels and fix spacer block to guardrail posts
Step 4. Connecting the W-Beam Guardrail Panels to the Posts
Step 5. Repeat Steps 2, 3 and 4
Step 6. Delineation (if required)
Installation Criteria for Road Crash Barriers
Please observe the following guidelines to install barrier.
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.
