The solid structure fence adopts a solid lock structure, which is mainly used for the wild outer fence to protect deer, horse, cow, sheep, goat and other cattle. Prairie fences and farm fences. It can be installed quickly and with fewer fences. This means that fixed knots reduce costs and reduce maintenance compared to other wire constructions. 1.Materials: High-strength galvanized iron wire; High-strength zinc plated steel 2.Surface treatment: Class A: Electro galvanized fixed knot joint fencing(zinc coated:15g/m²) Class B: Hot dipped galvanized fixed knot joint fencing(zinc coated:30-50g/m²) Class C: Heavy hot dipped galvanized fixed knot joint fencing(zinc coated:220-280g/m²) 3.Technical parameters: Wire diameter and tensile strength: horizontal wires: diameter 2.5 mm, tensile strength 1100-1300N/mm² vertical wires: diameter 2.5 mm, tensile strength 600-850N/mm² knot wires: diameter 2.2 mm, tensile strength 400-525N/mm²
