Import Arch Roof Roll Forming Machine — Buy in Bulk from Supplier in China

The Arch roof roll forming machine from Yingkou Bohai Machinery Equipment Manufacture Co., Ltd. is a dedicated production line for forming arch-shaped metal roofing sheets with consistent cross-sections. It processes coil stock at a typical line speed of 12 to 20 metres per minute, forming galvanised or prepainted steel coils into profiles with standard thicknesses from 0.3 mm to 0.8 mm. The forming rollers are hardened and chromed to resist wear, and the cutting system is hydraulic with a typical tolerance of ±1 mm on length.

Material input is standard hot-dip galvanised steel coil with a typical yield strength of 230 to 350 MPa, or colour-coated coil to the same base specification. The machine can switch between multiple profile heights and radii by changing roller cassettes, with a typical radius range of 3 m to 12 m. Control is via a PLC with touchscreen HMI that stores up to 50 profile recipes, and the drive uses a 7.5 kW main motor with frequency inverter for speed control.

Arch roofing produced on this line is used in agricultural sheds, industrial warehouses and commercial buildings where curved roofs improve structural strength and drainage. Buyers are typically steel service centres and roofing contractors who require repeatable geometry and minimal secondary finishing. The machine is built for continuous operation in a factory environment with a typical power requirement of 15 kW and compressed air at 0.6 MPa for the hydraulic cut-off.

Yingkou Bohai Machinery Equipment Manufacture Co., Ltd. operates from No 139 East, Jinniushan Street in the Zhanqian district of Yingkou, Liaoning Province. The company is registered as an imported-tier supplier with a harbor trust tier, indicating it meets baseline verification for export capability. Its listed address places it within a recognized industrial zone for metal fabrication equipment in northern China, and the profile confirms it as a manufacturer rather than a trading intermediary.

The supplier’s profile does not state a published response rate or average response time, so buyers should expect to initiate contact through standard channels. The company’s focus is on roll forming machinery for roofing and cladding applications, and its product range aligns with industrial metal processing rather than consumer goods. No additional certifications, client list, or production capacity figures are provided in the available data.
