D91 Round Downspout Roll Forming Machine

Home Cold Roll Forming Machine Roof And Panel Roll Forming Machine D91 Round Downspout Roll Forming Machine | 0.4-0.7mm

Features and Advantages of Standing Seam Seaming Tools

This precision roll forming line produces D91 leakproof inner-lock round downspout from 0.4-0.7mm steel or aluminum coils. A 3Ton hydraulic uncoiler feeds coils up to 600mm width, matched with manual tail-reminder pre-shear to trim uneven strip ends. 15 forming stations with Φ75mm mirror hard chrome rollers deliver smooth pipe surfaces, plus a dedicated film applicator to protect aluminum against scratches. Cr12MoV hydraulic post cut-off with anti-drop lock creates scrap-free clean cuts, and high-end Siemens S7-1200 PLC stabilizes cutting length within ±2mm tolerance with full safety mesh cover.
