How does corrugated steel beam guardrail achieve excellent anti collision performance

Each transportation system comprises several interconnected elements, of which Highway Safety Protection System (HSPS) and guardrails form an important part of the protection system. The incorporation of the protection system and the selection of guardrails impact the safety of vehicles and occupants greatly. The guardrail industry is dominated by the corrugated steel beam guardrails which perform exceptionally well to minimise the impact of crash dwellings. For the last 27 years, Zhengda Steel Structure Co. Ltd. has been manufacturing quality and internationally approved corrugated steel beam guardrails. Numerous engineers and representatives of different departments of transportation have realized the extraordinary impact that unique corrugated steel beam guardrails have on protecting the safety of highways. This article will attempt to address the specific question by describing several technical elements and their applications.

The Best Crash Protection of Zhengda’s Corrugated Steel Beam Guardrail

The primary reason Zhengda’s corrugated beam steel guardrails are so advantageous in highway safety protection is their unparalleled crash protection. The guardrails have a wavy cross-section in their design, which helps soak up the energy of an impact during a guardrail collision. Because of the construction of the guardrail, the deformations are corrugated in a manner so that the kinetic energy of the colliding vehicle is partially converted to elastic potential energy, so that the guardrail does not keep as much of the impact energy. This reduces the overall impact of the collision with the guardrail on the vehicle and the passengers. The guardrail is thus made of good Q235 steel plate, which has a breaking capability of over 375MPa, and thus has a good strength that helps to ensure that it does not break in an accident and cause a further collapsing of the guardrail. On highway stretches with a design speed of 120km/h, ZHengda’s corrugated steel beam guardrail can withstand a 1.5 ton vehicle crashing at a 20-degree angle, thereby preventing the vehicle from getting over the guardrail and subsequently falling from an elevated surface, thus protecting the guard from loss of life and property.

WEATHER PROOF CORRUGATED STEEL GUARDRAIL

Highway guardrails get rained on, snowed on, and are constantly eroded due to weather and gases, and so weather striping is important to sinking long term safety. Coldstream's corrugated steel guardrails get hot dipped galvanized surface treatment per ASTM A123. The galvanized steel have 85um protective film, sealing the steel reinforcements for the outside corrosive environments formed on the guard to ensure there is no rust formed for 20 years, even on coastal high salt spray zones or for industrial sites with serious air pollution. Furthermore, for additional customization, weather striping is available to enhance more protective and corrosion resisting aesthetics. This means guardrails highway interstates will require less maintenance, ensuring consistent safety protection.

Zhengda Fence Guardrail Operational Efficiency

Zhengda Fence Guardrail is manufactured using standardized processes which streamline production\, facilitating Zhengda Fence to maintain high project quality and construction speed. Each guardrail is manufactured to a specification length of 4320mm and features a quick connector interface making securing multiple panels together an easy 10-minute job for a 2-member construction crew. The construction/service columns for each  guardrail section\, either the 80×80mm square post or the larger 114mm round post\, are pre-fabricated with fixed mounting recesses to eliminate the need for on-site drilling and subsequent construction delays. With 3 fully automated production lines and an annual release of 3000 kilometers of fully produced highway guardrail, Zhengda Fence is able to provide unimpeded supply to large highway construction projects. Zhengda Fence standardized profile guardrails are able to decrease installation time by 40%, impacting project completion schedules positively, for example, on a 100-kilometer highway construction project.

Strong Adaptability to Complex Highway Environments

**Zhengda** experiences diverse mountain and coastal routes, requiring strong adaptability from our guardrails. Corrugated steel beam guardrails can be customized further accommodating varying terrains. Mountainous highways with large inclines can utilize slope-adjustable guardrails. This way, the guardrails stay close to the pavement and maintain their anti-collision effectiveness. On highway bridges, guardrails have anti-glare shields (75mm plates) to lessen oncoming vehicle headlight glare that might impede a driver's vision, and improve night driving safety. Cleverly, the wavy design of the guard rails boasts good wind resistance, withstanding 10 force winds that are accompanied by coastal typhoons. This corrugated guardrail design translates into a dependable safety structure for diverse highway challenges.

Compliance with International Standards and Quality Certification

Zhengda's corrugated steel guardrail fully meets international standards in safety and has several certifications in quality, securing safety in highway safety projects. This guardrail has CE and ISO 9001 certifications and its performance indicators such as anti-collision rating, corrosion resistance, and structural adequacy meets standards set by Europe EN 1317, and China GB/T 31439. Our guardrail is adaptable to the standards of various countries and regions to suit export projects such as the United States AASHTO and Japan JIS. All guardrails are subjected to 100 percent quality inspection, including measurements, thickness of the galvanized layer, and impact testing of the performance prior to leaving the factory. Others who have completed highway projects in the world especially in Asia (Japan, Vietnam) and Africa (Liberia, South Sudan) have recognized the corrugated steel beam guardrail.

Comprehensive After-Sales Service and Long-Term Warranty

Being Zhengda's customer provides you access to the most extensive after-sales service and long-term warranty for the corrugated steel beam guardrails. Zhengda provides great assurance of the safety and stability of the highway projects provided to them from all over the world. They provide a two-year warranty with the guardrails and offer unlimited free repairs and replacements if the issue in question is a defect in their manufacturing. For big projects, they send their qualified technical teams to the site to assist guards with the install to ensure the guardrails are positioned and set to spec with designs. Zhengda also offers life-time spare parts supply, allowing customers to purchase verifiable spare parts at all times to keep up on the maintenance of the guardrails. They also have a customer feedback system that monitors how the guardrails are being utilized and provides support for their maintenance and replacement. This service provides peace of mind to highway management and engineering contractors. This is also why contractors trust Zhengda’s corrugated steel beam guardrails most.
