GNEE Steel's S350GD+Z160 Steel Plate Becomes Preferred Choice For Highway Guardrail Projects

 

Looking for trusted galvanized steel plate manufacturers in China? You've come to the right place. As a direct factory with 20 years of structural steel experience, GNEE Steel supplies EN 10346 compliant sheets at factory prices. Our S350GD+Z160 galvanized steel plate has recently emerged as the preferred choice for many highway guardrail projects across the country, thanks to its outstanding impact resistance and long-lasting corrosion protection.

 

Highway guardrails play a crucial role in ensuring road safety, as they need to absorb impact energy during vehicle collisions and prevent vehicles from going off the road. This requires guardrail materials to have high strength, good ductility, and excellent corrosion resistance. The harsh outdoor environment, including exposure to rain, snow, and road salt, further increases the demand for the durability of guardrail materials. The S350GD+Z160 galvanized steel plate from GNEE Steel meets all these requirements, making it an ideal material for highway guardrail construction.

The safety performance of highway guardrails largely depends on the mechanical properties of the materials used. The S350GD+Z160 galvanized steel plate has been carefully designed and tested to ensure it can withstand the impact of vehicles and protect the safety of passengers.

 

Property	Highway Guardrail Standard Requirement	GNEE Steel S350GD+Z160 Test Result
Yield Strength (MPa)	≥ 350	360 - 410
Tensile Strength (MPa)	420 - 550	430 - 540
Elongation (%)	≥ 20	≥ 22
Impact Toughness (20℃, J)	≥ 35	≥ 45
Bending Performance (180°, d=2t)	No cracks	No cracks

 

The high elongation and impact toughness of the S350GD+Z160 galvanized steel plate allow the guardrail to bend and deform in a controlled manner during collisions, effectively absorbing impact energy and reducing the damage to vehicles and passengers. The bending performance test shows that the product can withstand 180° bending without cracks, which is essential for the forming process of guardrails and ensures the structural integrity of the guardrail during installation and use.

 

 

Highway guardrails are exposed to the outdoor environment all year round, facing the erosion of rain, snow, and road salt, which can easily cause corrosion and reduce the service life of the guardrails. The S350GD+Z160 galvanized steel plate from GNEE Steel adopts a high-quality hot-dip galvanizing process with a zinc coating weight of 160g/m², providing strong corrosion protection.

 

The zinc coating forms a sacrificial anode protection layer on the surface of the steel plate. Even if the coating is slightly damaged, the zinc around the damaged area will continue to protect the steel from corrosion. This unique corrosion protection mechanism ensures that the S350GD+Z160 galvanized steel plate can maintain good performance in harsh outdoor environments for a long time.

 

According to our field tests and customer feedback, the S350GD+Z160 galvanized steel plate used in highway guardrails has a service life of more than 15 years, which is significantly longer than the 10-12 years of ordinary galvanized steel plates. This not only reduces the frequency of guardrail replacement but also lowers the maintenance costs of highways.

 

 

To meet the diverse needs of highway guardrail production, GNEE Steel provides the S350GD+Z160 galvanized steel plate in a variety of specifications, including different thicknesses, widths, and lengths. This allows guardrail manufacturers to produce guardrails of different types and sizes according to specific highway design requirements.

 

Product Type	Thickness (mm)	Width (mm)	Length (mm)	Guardrail Component
Hot-Dip Galvanized Sheet	2.5 - 4.0	310 - 500	4000 - 12000	Guardrail panels
Hot-Dip Galvanized Coil	2.5 - 3.5	310 - 500	Custom (10 - 25 tons/coil)	Continuous roll forming of panels
Cut Plates	4.0 - 6.0	200 - 300	1000 - 3000	Guardrail posts, brackets

 

The hot-dip galvanized coils are particularly suitable for continuous roll forming of guardrail panels, which can improve production efficiency and ensure the consistency of product quality. The cut plates are ideal for manufacturing guardrail posts and brackets, as they can be easily processed into the required shapes and sizes.

 

 

With the continuous development of China's highway construction, the demand for high-quality guardrail materials is increasing. The S350GD+Z160 galvanized steel plate from GNEE Steel has made a significant contribution to improving the safety level of highways.

 

In a recent highway expansion project in eastern China, the S350GD+Z160 galvanized steel plate was used for the guardrails of the entire section. After more than a year of use, the guardrails still maintain a good appearance and structural integrity, without any signs of corrosion or deformation. The local highway authority stated that the use of this high-quality galvanized steel plate has greatly enhanced the safety performance of the highway and reduced the maintenance workload.

 

The S350GD+Z160 galvanized steel plate from GNEE Steel is an excellent material for highway guardrail projects, with excellent mechanical properties, long-lasting corrosion protection, and suitable specifications. It provides a reliable guarantee for the safety of highways and helps reduce maintenance costs.
