The physical factory of national standard landscape guardrails has a long service life. The grounding resistance of the lightning - proof guardrail and metal structure of Longbang Traffic Facilities is less than 10 ohms, and the upright column is welded to the grounding flat steel. Protect surrounding facilities from lightning strikes, and test the grounding resistance once a year to ensure good conductivity. The modern minimalist style landscape guardrail uses extremely simple geometric shapes, with fine lines outlining the spatial contour. The cross - section of the stainless - steel square tube is 30×30 mm, with a wall thickness of 2 mm, and the surface is wire - drawn. They are arranged at a spacing of 15 cm, forming a semi - transparent virtual partition. The upright columns are hidden in the green belt, with only the cross - beams and vertical rods exposed, creating a light visual effect. It is 1 meter high, with a 10 - cm suspension at the bottom, creating a floating feeling. This kind of guardrail is suitable for modern - style squares and commercial blocks, simple yet elegant, with a moderate cost (about 800 yuan per meter).

The river rescue guardrail of Longbang Traffic Facilities is equipped with a life - buoy storage rack and a ladder every 100 meters, made of stainless steel with two life - buoys inside.

The landscape guardrail for children's playgrounds needs to be brightly colored, safe and non - toxic, using a structure of PE plastic - coated steel pipes. The steel pipe has a diameter of 48 mm, a wall thickness of 3 mm, and the outer layer of PE plastic is 3 mm thick, with colors such as red, yellow, blue and green available. The guardrail is 0.8 meters high, with a spacing of 1.2 meters between the upright columns and two layers of cross - beams. All sharp corners are rounded with a radius of not less than 20 mm. There is no gap between the bottom of the guardrail and the ground to prevent children's hands and feet from getting stuck. The PE plastic is added with an anti - ultraviolet agent and will not fade for 5 years when used outdoors. This kind of guardrail is affordable, about 300 yuan per meter, and is the standard configuration for kindergartens and community children's playgrounds.

The Chinese - style garden landscape guardrail emphasizes the combination of virtual and real and the creation of artistic conception, often using ice - crack or square - pattern hollowed - out patterns. The pre - cast concrete components are made of GRC material, pressed by a mold, with a pattern fineness of up to the millimeter level. The component size is 60×60 cm, with a thickness of 5 cm, and the surface is sprayed with antique copper paint. The upright columns are finished with stone - like paint to match the architectural style.
