The guardrail beside the ancient city wall is a city - brick - colored terracotta railing fired at 1200 degrees Celsius, with a compressive strength of 50 MPa and a water absorption rate ≤ 8%. It imitates the stone railing of the Ming Dynasty, with scroll grass pattern balustrades and lotus - seat baluster columns. The mortise - and - tenon structure is caulked with tung oil mortar, and the foundation is concealed without damaging the ruins. Chinese garden landscape guardrails pay attention to the combination of virtual and real and the creation of artistic conception, and often use ice - crack patterns or back - character patterns for hollow - out designs. The precast concrete components are made of GRC material, formed by mold pressing, and the pattern fineness reaches 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 columns are finished with stone - like paint to match the architectural style. The height of the guardrail is 1.2 meters, and a courtyard lamp in the shape of a palace lantern is installed every 3 meters. At night, the light and shadow are projected on the ground through the hollow - out patterns, creating a wonderful light - and - shadow effect.

Garden landscape guardrails pursue harmonious coexistence with the natural environment and often take the form of a low dry - stacked rubble wall, with a height of 40 - 60 cm, which has the functions of defining space and providing a place to sit and rest. The rubble is selected from local river pebbles or mountain - skin stones, with different sizes arranged in a disorderly and orderly manner. The gaps are filled with gravel or planted with drought - tolerant plants such as moss and sedum. The top of the wall is paved with anti - decay wooden boards, 30 cm wide, forming a natural seat. This kind of guardrail is low - cost, eco - friendly, and in line with the artistic conception of the landscape garden, and is widely used in parks and green spaces.
