highway guardrail can be divided into cement guardrails (materials:powdered inorganic adhesive materials with water-hardening properties), steel pipe guardrails, cast iron guardrails, plastic guardrails (structure: synthetic resin, plasticizer, stabilizer, colorant), hot-pressed plastic-coated guardrails and stainless steel (stainless acid-resistant steel) guardrails, according to different materials;
According to installation positions, highway guardrail can be divided into central isolation guardrails, guardrails for motor vehicles and non-motor vehicles, pedestrian guardrails, greenelt guardrails, etc.
Some cities often use cement guardrails, steel pipe guardrails, etc. due to economic constraints, but the lack of detailed design results in poor aesthetics and poor performance of guardrails, which also affects the urban environment;
Some cities emphasize decoration but ignore the inherent "safety" function of highway guardrail: for example, some cities use stainless steel (stainless acid-resistant steel) guardrails, but fail to attach importance to the optical design of guardrails, and stainless steel guardrails instead cause light pollution, causing glare and affecting safety;
The irregular design and improper position of highway guardrail installation affect the urban landscape; some guardrails have no vertical bar gaps or the gaps are too large, making it easy for pedestrians to climb over them and posing safety risks;
Some guardrails have poor strength, and can be separated and connected manually, making them vulnerable and futile; some guardrails have many welding points, and the surface of the lower layer is not treated for corrosion resistance, and the surface is painted or immersed in plastic, resulting in low corrosion resistance, easy rusting and short service life.
Low maintenance: no decay, no corrosion, no fading, no need for daily maintenance, and no pollution to the environment. The waveform guardrail plate of anti-collision guardrail on the expressway is the main form of semi-steel guardrail, which is a continuous structure composed of corrugated steel guardrail plates spliced and supported by columns.
Long service life: using first-class raw materials to produce, the highway guardrail does not deform, fade, age, crack, peel, or embrittle at temperatures between -50 and 70 degrees Celsius.
High strength: It is equipped with a steel liner treated with anti-corrosion, which enables it to have good strength and impact resistance.
Beautiful appearance: it comes in various colors such as white, blue, red, and green, and has a bright color and strong decorative properties, which can be used in combination with other material guardrails.
Easy installation: the highway guardrail adopts a patented support-insertion connection or a proprietary connection accessory for quick and easy installation and firm fixation.
