This offers a full range of reliable auxiliary equipment for metal processing, pipe production, and profile manufacturing lines. It includes steel strip pulling machines that deliver stable traction and precise material conveying via motor drive and steel wire rope structure, replacing manual operation and supporting smooth production flow for steel strips, welded pipes, and profiles. Filament winding machines efficiently collect high‑frequency weld seam scrap wire, preventing line downtime, equipment jams, and safety risks for continuous welding production. Automatic column welding machines feature a heavy‑duty gantry frame and dual‑station heads, providing high‑efficiency, consistent welding for steel structure columns and mechanical components, greatly improving productivity and quality stability. All equipment is designed for stable performance, durable construction, and easy integration into production lines, widely used in metal processing, steel structure, pipe making, and machinery support fields. These auxiliary units enhance automation, reduce labor intensity, and ensure efficient, safe, and continuous industrial production.
