Import Cutting Concrete — Buy in wholesale FOB from Supplier in China

The Jining Dingcheng DC-400, DC-500, and DC-500C concrete cutting machines are gasoline or diesel-powered saws designed for precision cutting of asphalt, concrete pavements, and stone in municipal and infrastructure projects. The DC-400 has a 400mm blade diameter and 130mm cutting depth, while the DC-500 features a 500mm blade and 180mm depth, with the DC-500C extending to 230mm depth using a 600mm blade. All models operate at 3600rpm with a cutting speed of 1 to 2.5 meters per minute, powered by Honda GX390 or GX620 engines rated at 8.5kW and 20kW respectively. The machines are hand-pushed, with integrated water tanks of 38L to 49L to suppress dust during operation.

These machines use hardened steel blades with standard industrial tolerances for concrete cutting, typically 1.8mm to 2.5mm thickness, matched to the blade diameter and engine torque. The cutting depth is adjusted via screw mechanisms, not hydraulic systems, which is typical for portable, non-industrial-grade cutters. The engines are air-cooled, four-stroke, with oil capacities between 1.1L and 1.8L, and fuel consumption ranges from 1.1L to 2.2L per hour using unleaded gasoline above 90 octane. These are standard specifications for portable concrete saws in the construction equipment category, not heavy-duty track-mounted systems.

Buyers include municipal road maintenance teams, bridge construction contractors, and utility installers who require precise, shallow cuts for expansion joints, pipe routing, or pavement repair. The machines are packed in standard export crates measuring 1450x1000x1100mm and weigh approximately 130kg to 140kg depending on model. Trade terms are typically FOB Qingdao or Shanghai, with lead times of 15 to 25 days after deposit. Buyers should confirm blade compatibility, water pump function, and engine emission compliance with local regulations before shipment.

Jining Dingcheng Industrial & Mining Equipment Co., Ltd. is a manufacturer based in Jining, Shandong Province, China, with a harbor-tier verification status indicating active trade engagement. The company specializes in portable construction equipment, particularly concrete and asphalt cutting machines. Its listing shows no claims about company history, employee count, or annual turnover. The response rate and average response time are not recorded, indicating limited buyer communication history on the platform.

The supplier does not claim certifications beyond CE marking, and no third-party audits, factory photos, or client references are provided. The product line is limited to the DC-400, DC-500, and DC-600 models, with no evidence of custom fabrication or R&D capability. Buyers should treat this as a direct manufacturer of standard machinery, not a distributor or service provider. Verification signals are minimal, so technical validation through pre-shipment inspection is strongly advised.
