Scope

Scope: This standard applies to coated steel wires used in agricultural planting frames produced by hot-dip galvanizing, and can also be applied to coated steel wires for grape planting frames, hops planting frames, and simple plastic vegetable greenhouse frames. This product is suitable for applications requiring corrosion resistance. Main technical content: 1. The coating categories in this standard are divided into three types: zinc coating, zinc-5% aluminum-rare earth alloy coating, and zinc-10% aluminum rare earth alloy coating; 2. Dimensions and shapes: Based on the actual usage, habits, and feedback from users, this standard specifies the bundle diameter and bundle weight of coated steel wires for agricultural planting frames to meet the requirements of field construction environments in agriculture; 3. Technical requirements: This standard sets specific requirements for the raw materials, mechanical properties, and coating quality of coated steel wires for agricultural planting frames. Compared with other similar product standards, it highlights several provisions such as high strength and high elongation (L0 = 100mm) ≥ 16, and excellent winding performance, ensuring the performance characteristics of coated steel wires for planting frames; 4. Raw materials: Table 3 in this standard adopts the provisions of Table 1 in the American standard ASTM B 750-2009, compared with the provisions in the YB/T 5357-2009 "Steel Wire Coating Zinc or Zinc-5% Aluminum Alloy" standard, which adopted the provisions of Table 1 in the ASTM B 750-1994a standard. This standard adopts the new version of the American standard; 5. Mechanical properties: Based on user requirements, this standard sets higher requirements for strength, elongation, winding performance, and reverse bending; 6. Coating quality: The weight of the steel wire coating is determined according to user requirements and the actual situation of domestic metal product manufacturers, referring to the AH a
