[0002] With the increasing demand for privacy and security in residential courtyards, balconies, commercial spaces, and public green spaces, the market for outdoor fencing products is developing rapidly.
[0003] Currently, the mainstream types of fences include wooden fences, metal fences, and WPC wood-plastic composite material fences. Wooden fences have a natural appearance but are prone to rot and cracking, and have high maintenance costs; metal fences (wrought iron, aluminum, etc.) have high strength but a rigid appearance, are prone to rust, and have complex installation methods; WPC wood-plastic composite material fences have the advantages of corrosion resistance, moisture resistance, and maintenance-free operation, but conventional WPC wood-plastic composite material fences have a single installation method and are mostly buried, which cannot be applied to hard surfaces such as tiled floors, concrete platforms, and balconies; exposed bases and screws affect aesthetics. Traditional bases are completely exposed after installation, which affects the appearance and is easily corroded or dismantled; stability is generally poor. WPC boards mostly rely on slot assembly, have weak wind resistance, and the boards are prone to loosening; maintenance is inconvenient, and repairs require disassembling the entire fence, resulting in high maintenance costs.
[0004] To address this, we propose an outdoor fence with a concealable base, which solves the comprehensive needs of WPC wood-plastic composite fences for "fast installation + concealed base + modular combination + strong structural stability". Utility Model Content
