Advantages of Structural Design for Efficient Impact Absorption
From innovative guardrail designs, the company's Metalguardrail has the highest-impact absorption levels because of the engineering guardrail's geometry absorption. The guardrail has panels in the shape of waves, unlike panels that are shaped flat. These panels can progressively deform instead of undergoing plastic deformation. Also, because of the guardrail's wave shape, there are more contact points with vehicles. This architecture allows for the prolongment of impact force, which enables more plastic deformation absorption, impact energy dispersion, and elastic energy from the guardrail. Moreover, the guardrail's spacing of the columns and manner of connectivity are highly optimized computational models for the coordination of the entire set of structures for force-bearing systems. The design of capturing the energy for absorption rather than resisting it was fully realized with the waves guardrail. It controlled deformation rather than sudden breakage. It was optimized for guiding vehicles into deceleration without secondary impact collisions.
Impact Resistance Selection of Quality Materials
Metalguardrails selects quality materials to manufacture its corrugated steel beam guardrail to ensure dependable impact absorption performance. For sudden impact toughness and ductility, corrugated panels are constructed of low-alloy Q235 or Q355 steel, allowing for significant plastic deformation to occur without fracturing. Protective support for the guardrail columns is provided by thick walled seamless steel pipes or by hot-rolled section steel, also allowing for flexibility in tandem with the support of the panel deformation. All steel components are hot dip galvanized or galvanized then powder coated to ensure that the mechanical properties of the steel remain stable in bridge exposed environments and fluctuating temperatures. Such high quality materials ensure the corrugated beam steel guardrail has dependable impact absorption performance for the entirety of its service life.
**Metalguard Rails**’ corrugated steel beam guardrails are designed and manufactured well within the the scope of domestic and international bridge safety standards and are noted for their impact absorption capabilities. Each of the guardrails are designed and manufactured for differing traffic volumes and bridge speed limits. For instance, our top of the line corrugated steel beam guardrails are designed to absorb impact energy and vehicular control of 10,000 kg (10 ton) vehicles traveling at 80 km/hr, and are designed to withstand vehicles breaking through the guardrails and potentially falling off the bridge. Each of our beam guardrails designed for differing traffic volumes and speed limits have all been certified based off the impact performance of,, energy absorption and control of resulting deflection of the guardrails and vehicular guidance. Each of these attributes of impact absorption and deflection control meets or exceeds the minimum bridge engineering safety standard. All of our beam guardrails have been designed to provide performance based on impact absorption and deflection control, and provide impact and deflection control safety for all types of bridges.
Examples of Impact Protection Function Verification from Use Case Scenarios
Many bridge building activities have confirmed that Metalguardrails' corrugated steel beam guardrail have extraordinary impact absorption capacity. In a City Overpass, a truck lost control and crashed into one of the corrugated steel beam guardrails beam and guardrails. Due to the absorbing corrugated panel deformation energy of the guardrail, the truck was decelerated and restored to the safe region without the driver getting injured. On a high structure bridge, the impact energy of a hit a passenger car was absorbed and ruined no bridge structure. These instances confirm that the corrugated steel beam guardrail protects the impact absorber.
Why Metalguardrails Guardrails Are The Best Choice for Bridges
In conclusion, Metalguardrails’ outstanding impact absorption performance for bridges is due to professional structural design, high quality material, and strict adherence to safety standards. With rich R&D and advanced automation, the company can tailor solutions for different types of bridges and traffic patterns along with required safety levels. These include impact absorbing guardrails, and installation, maintenance, and training support to ensure it meets expected performance standards. For protective engineering, safety, reliability, and durability required, Metalguardrails’ impact absorbing guardrails provide the best safety for bridge transport.
