Import Br140 4-Roll Section Bending Machine — Buy in Bulk from Supplier in China

The Br140 4-roll section bending machine from Nantong Borisbang Industrial Technology is a hydraulic four-roll system designed for rolling steel sections into circular, arched, and spiral forms. All four work rolls are driven, with the upper roller fixed and the lower roller movable laterally via cylinder pressure to clamp the profile. Left and right side rollers also move laterally with hydraulic actuation, enabling pre-bending, rolling, and rounding in a single setup. A digital display shows real-time rolling status, and a vertically upright arrangement facilitates profile loading and unloading safety.

The machine employs roller bearings with high load capacity on the radial positions, and the guide rollers feature mechanically driven lift and rotation for correcting asymmetric sections. A combined dust cover protects the gearbox and bearings from iron filings and scale ingress during operation. The four-roll drive configuration eliminates slippage between roll and profile, a common defect in three-roll designs when handling higher-yield structural grades. The Br140 designation indicates a larger capacity class than the Br100, with stronger frame and drive components to match.

Buyers typically include heavy fabrication contractors, bridge and stadium constructors, shipyards, and machinery manufacturers requiring formed structural rings and arches. The machine handles angles, channels, beams, and custom sections within its modulus range. The vertical layout suits floor-level feeding with overhead crane assistance. Prospective purchasers should request the complete section capacity table, including minimum bending diameter for each standard profile, and confirm motor power and hydraulic specifications to match their production cycle demands.

Nantong Borisbang Industrial Technology operates from Haian County, Nantong, Jiangsu Province, China, postal code 226600. The harbour trust tier signals basic marketplace verification. The response rate shows 0.00 percent with zero average response hours, indicating no tracked buyer engagement metrics at the time of data capture. The Jiangsu location positions the supplier within a dense network of machine tool and metalworking equipment manufacturers with access to foundry, forging, and precision machining subcontractors.

No establishment date, ownership structure, factory floor area, employee count, annual turnover, export volume, or client list appears in the source profile. ISO 9001, CE compliance, or other conformity assessment details are absent. The supplier description concentrates on product features rather than corporate credentials. Buyers intending to place substantial orders should conduct independent verification of business registration, tax status, and manufacturing capability through direct factory audit or appointed inspection agency before payment.
