Guardrail
A guardrail is a longitudinal system of roadside obstacles used to prevent faulty vehicles from hitting roadside obstacles. By redirecting vehicles off the road, guardrails away from more serious hazards, including construction (e. g., sign structures, culvert entrances, telephone poles) and nature (e. g., trees, rock outcrops). The guardrail prevents vehicles from descending from a steep embankment or turning into the middle of the road and oncoming traffic. In some cases, the reason for installing a guardrail is not to protect the driver from obstacles (e. g., road closed roadblocks and obstacles protecting pedestrians or sensitive areas). When a vehicle hits the guardrail, the driver and passengers will encounter some risks. The guardrail does not eliminate the possibility of injury or death. The main objective of the road engineer is to provide an adequate clearance without any obstruction and area of concern. The only case of installing a guardrail is that the guardrail is less risky to vehicles than to unshielded roadside obstacles. Before deciding to install the guardrail, always consider alternatives to the guardrail installation (e. g., removing or relocating the obstruction). When providing full clearance is impractical, using guardrails or other roadside obstacles provides an attractive option, as it significantly improves the safety of vehicles leaving the road.
The guardrail system is currently used for the new installation of the standard guardrail and the corresponding end-processing. A non-proprietary steel or wooden column W-type steel guardrail system meeting the MASH Test Level 3 standard. The system adopts typical W steel guardrail with the following characteristics:
31-inch guide rail top mounting height and + / -1-inch tolerance (see section 3.5, barrier height). • Minimum 6 foot long W6 x 9 steel column or 6 inch x 8 inch wooden post
O longer columns can be used (e. g., 7 or 9 feet) (see section 5.1 "reinforced guardrail").
• 6 inch x 8 inch wired or non-wired wood or composite plastic offset blocks Span middle rail joint Remove the joint (the weakest link) from the post and the highest stress point at the shelter. For installation, contractors must use 12 ft 6 in or 25 ft long W steel panels, but they can use 6 ft 3 panels at the end of the run.
The clusion panels are usually made of wood or composite plastic, 6 or 8 inches deep and 6 inches wide.
The strong column W-type beam meets the NCHRP 350 test level 3 standard and is mainly used before adopting the MASH test standard.
The strong column W section steel guardrail system is installed at different heights, ranging from 27 to 29 inches.
Shiteng Technology Group Co., Ltd. is a company that has been dedicated to providing top-quality metal products using advanced technology. Its main focus is on manufacturing steel highway guardrails and anti-collision highway safety roller guardrails. The company takes pride in ensuring the safety of drivers, pedestrians, and park-goers from the dangers of the road with its durable and reliable safety barrier systems, A guardrail is a crucial component of any roadside barrier system. It is installed to prevent vehicles from impacting roadside obstacles, thus keeping drivers and passengers safe from serious hazards. The primary goal of road engineers is to provide adequate clear zones free of any obstacles and areas of concern. Guardrails are only installed when they present a lower risk to vehicles than unshielded roadside obstacles. In cases where it is not practical to provide a full clear zone, the use of guardrails or another roadside barrier significantly increases the safety of vehicles departing the roadway, One of the reliable and strong guardrail options offered by Zhejiang Shiteng Technology Group Co., Ltd. is the Thrie beam guardrail terminal end. This safety device is designed to protect drivers, vehicles, and pedestrians in hazardous areas. It is constructed from galvanized steel, ensuring durability and resistance to corrosion. This makes it suitable for applications requiring high-visibility warnings such as reflectors and detectors, offering greater visibility and security where necessary, The Thrie beam guardrail terminal end is designed to absorb the impact of collisions, providing an effective barrier between oncoming vehicles and whatever is in their path. It is equipped with rounded edges, minimizing the risk of debris and enhancing the structural integrity of the guardrail. The guardrail is also customizable and can be used in various applications, such as industrial complexes, airports, and public parks, where safety is a top priority, One of the unique features of the Thrie beam guardrail terminal end is its effective installation, allowing for immediate installation to a post or a side-by-side installation with other guardrails. It offers optimal safety performance, providing long-lasting protection even in high-impact crash scenarios. The solid steel construction and hot-dipped galvanized layer offer robust anti-corrosion and deformation resistance, minimizing any danger of skidding or dislodging, In terms of maintenance and service, the guardrail is designed to be easily maintained and repaired, offering a longer lifespan and fewer potential hazards. It is available in several different sizes and colors, making it easy to match to any application. This makes it a versatile and reliable option for ensuring the safety of drivers and pedestrians, In conclusion, the Thrie beam guardrail terminal end offered by Zhejiang Shiteng Technology Group Co., Ltd. is a durable and corrosion-resistant barrier system that can provide long-lasting protection and durability. With its customizable design and maintenance-friendly features, it is an ideal solution for ensuring the safety of drivers, pedestrians, and park-goers from the hazards of the roads. The company's focus on providing high-quality metal products with professional technology makes it a trusted provider of safety barrier systems
