从China供应商批量进口750 Deduction Trough Roll Forming Machine

The 750 deduction trough roll forming machine from Jinchengxin Roll Forming Machinery Factory produces profiled metal troughs with a 750 mm cover width, fed from coil stock up to 1000 mm wide. The forming stations progressively shape flat strip into a corrugated profile with a wave height of 51 mm and wave length of 185 mm, dimensions that suit water drainage channels, agricultural guttering, and roofing substrate applications. The machine architecture follows the deduction trough configuration, a profile geometry common in Chinese and Southeast Asian construction markets where interlocking or lapped seams are formed without additional seaming equipment.

Roll forming tooling for this profile typically employs D2 or Cr12MoV alloy steel for the forming rollers, heat-treated to 58-62 HRC to maintain edge definition over high production volumes. The machine frame is fabricated from welded structural steel with linear guide rails or shaft-and-bearing arrangements to maintain upper-lower roll alignment within ±0.15 mm over the forming length. A decoiler, coil straightener or flattener, and servo- or mechanically-driven feeder precede the forming mill, followed by a hydraulic or flying shear cut-off and automated stacking system. The source confirms customisable features; buyers should specify whether they require fixed-cut or flying-cut shearing, and whether the decoiler capacity matches their coil weight (typical range 5-10 tonnes).

Target buyers include metal building component manufacturers, agricultural infrastructure contractors, and roofing system integrators in markets where 750 mm trough modules are standard. The 51 mm wave height provides structural depth for moderate span capability without secondary purlins. Jinchengxin notes high output and user-friendly operation, but does not state line speed in metres per minute or motor power. Confirm these figures directly, as they determine labour and energy cost per metre. Buyers should also clarify whether the quoted wave dimensions are nominal or finished, accounting for springback in the base material (typically 0.4-0.8 mm galvanised steel or 0.5-1.0 mm aluminium).

Jinchengxin Roll Forming Machinery Factory is located at 104 State Road, Botou, Hebei Province 062150, China. Botou is a recognised centre for roll forming machinery manufacturing, with numerous factories serving domestic and export markets for roofing, racking, and construction profiles. The supplier tier is imported and trust tier is harbour, with a 0.00 percent response rate and zero recorded average response hours. No information is provided about factory floor area, workforce, design engineering staff, or quality management system certification. Buyers should conduct due diligence through direct enquiry or factory visit given the lack of response history.

The listing positions Jinchengxin as offering customised solutions and high production efficiency, but does not disclose client references, installed base, after-sales service network, or spare parts stocking policy. No mention is made of ISO 9001, CE marking, or other compliance documentation. The factory's proximity to Tianjin Port (approximately 200 km) offers potential logistics advantages for containerised export, though inland haulage costs from Botou should be factored into landed cost calculations. Prospective buyers should request current factory audit reports, reference customer contacts, and video documentation of operating machines before committing to purchase.
