A designer of a guardrail system has an obligation to ensure that:
the system is designed to be safe and without risks to health when used properly;
the design, if given to someone else to use, is accompanied by information about the way the plant must be used to ensure health and safety.
The designer should consider:
the type of structures the system may be attached to; and
the loads that may be applied if a worker falls against the guardrails.
The Australian Standard AS/NZS4994 (Int) Temporary Roof Edge Protection for Housing and Residential Buildings provides guidance on the testing of roof guardrail systems.
The Australian Standard AS/NZS1657 Fixed Platforms, Walkways, Stairways and Ladders – Design, Construction and Installation provides guidance on design loadings for permanent guardrailing.
The manufacturer of a roof guardrail system has obligations to ensure that:
the system is manufactured to be safe and without risk to health when used properly;
the system, when manufactured, is tested and examined to ensure it will be safe and without risk to health when used properly; and
the system, when supplied to another person, is accompanied by information about the way it must be used to ensure the health and safety of users.
A supplier of a guardrail system has an obligation to either:
examine and test the system to ensure it is safe and without risk to health when used properly; or
ensure the manufacturer has given an assurance that the system has been examined and tested to ensure it is safe and without risk to health and safety when used properly.
The supplier also has an obligation to provide information about how the system must be used to ensure health and safety.
The supplier (Wuhan Dachu Traffic Facilities Co., Ltd) should provide installation instructions to the installer, including the following as a minimum:
details about the supporting structure - member sizes, material type and strength;
maximum guardrail post spacing; and
connector details (i.e. bolting, screwing or clamping method).
The supplier should obtain information from the truss supplier about stiffening required to withstand additional loads.
An installer of a guardrail system has obligations to:
install the system in a way that is safe and without risk to health; and
ensure that nothing about the way the system was installed makes it unsafe and a risk to health when used properly.
To meet these obligations, the installer of the system should:
ensure they have the appropriate competencies (through training, qualification and/or experience) to install the system;
follow the manufacturer's and/or supplier's instructions;
provide written verification about the system at handover to the person being supplied the system; and
ensure the Work Method Statement is completed where applicable and given to the principal contractor before installation work commences.
Handover information should include written verification that:
the guardrail system and supporting structure are structurally adequate (eg. verification by a suitably qualified engineer); and
the guardrail system has been installed in accordance with the supplier's instructions.

Introduction of Thrie-beam Galvanized Corrugated Beam 3.0:
There are two types of guardrails, We are more likely to see w-beam, but seldom thrie beam.
The three-wave guardrail usage: express road, provincial road, county side road, township road, mountain road, seaside road and so on.The specification of the three corrugated beam is 4320 mm, the wave width is 505 mm, the wave height is 85mm and the plate thickness is 4mm. Theoretical component: 102kg, cooperation 130*130 square pipe column.

| Thrie beam Guardrail |
Features of Thrie-beam Galvanized Corrugated Beam:
1, High-quality range ( Q235/Q345) material，the surface is hot dipped galvanized, the effect of anti-corrosion and waterproof is better.
2, Wider panel, larger anti-collision area, and batter anti-collision effect.
3, Smooth edge design. Prevent accidental cutting when installation and more safety.
4, Comprehensive protection: every part of the plating can be plated with zinc, which can be fully protected even in the depression, sharp corners and hiding places.
5, Durable: in the suburbs, the standard hot-dip galvanized rust resistance can be kept for more than 50 years without having to be repaired; In urban or offshore areas, the standard hot-dip galvanized coatings can be kept for 20 years without having to be repaired

Function of crash barrier
Many people would ask what is the Function of crash barrier? Why cannot we change it with mesh fence or something lighter than crash barrier?
Crash barrier function is more than what we usually think!
Guardrails keep cars running in their designated lanes and avoid colliding with each other
Guardrails can prevent cars from falling over edges of roads on hills while traversing through mountainous terrains with sharp turns
Guardrails can keep vehicles on track in housing complexes with large driving spaces
Also W-beam can protect vehicles from colliding against fixed natural or man-made objects like boulders, trees, rocks, and so on.
How guardrails work
To people not in the guardrail business, the guardrail may seem like just a simple structure. But a lot of scientific and engineering acumen has to go into its making for proper functioning. The end terminal of a guardrail is made of a flat and strong piece of steel, which is made with the view of withstanding any collision with a car.
So, if a car hits the guardrail, it is made to stay on the highway rather than go berserk and errant due to the unexpected bang. So, by stopping the car from rolling over uncontrolled, physical damage to drivers and passengers can be prevented or minimized to a large extent. The making of the face of the guardrail is also important to determine how far the car will travel before coming to a halt once it has come in contact with the guardrail.
With this knowledge, you will be able to appreciate how crucial it is to assemble the components of the guardrails in order to ensure their effectiveness.

What type of Mitigation Crash Barriers you really need?
There are many different kinds of safety barriers and all of them are Mitigation Crash Barriers. But you cannot install the same kind of guardrail regardless of the purpose and the location.
Pictures above are two kinds of Crash Barriers, the first one is for roadway and the second one is only for a temporary purpose. The first roadway guardrail is mainly for highway, however, you can also use it to protect your house from car collision if your car is along a busy street. Because you never know when a car would become errant.

How w-beam guardrail is made and installed
Roadway guardrails are normal in our daily life. We can see them in the express way, city road and sometimes even countryside. However, not everybody have the idea have guardrail is made.
The picture below shows the procedure of guardrail making.
After a road is built, especially the highway, we need try our best to ensure when some cars become errant, they can get protection to the biggest extent, guardrail or crash barrier is needed. But how to install guardrail?
I believe you all get a clear idea about how the guardrail is made and installed. If you need to know more about road safety facilities, you can Google Wuhan Dachu Traffic Facilities to know more.
