护栏网是以低碳钢丝、镀锌铁丝为原料，通过焊接或编织工艺制成的网状隔离设施，表面常采用塑喷、镀锌或浸塑处理以增强耐腐蚀性。其主体结构分为带边框型（方钢管立柱与矩形边框固定）和无边框型（圆/方立柱搭配网格），兼具防护与装饰功能。
广泛应用于工农业、畜牧林业及市政交通等领域，承担区域隔离、边界划分及场地防护作用。
Guardrail mesh is a mesh isolation facility made of low-carbon steel wire and galvanized iron wire through welding or weaving processes. The surface is often treated with plastic spraying, galvanizing or dipping to enhance corrosion resistance. Its main structure is divided into framed type (fixed with square steel pipe columns and rectangular frames) and frameless type (round/square columns with grids), which have both protective and decorative functions.
Widely used in the fields of industry, agriculture, animal husbandry, forestry, and municipal transportation, it undertakes the functions of regional isolation, boundary delineation, and site protection.
