AI-Powered supplier vetting
SummaryWeifang Shengao Machinery Co., Ltd. is a limited company focused on mechanical parts, hardware, metal tools, CNC machine tools, and related components. It identifies as a professional technical supplier and offers 3D software design and broad customization services, including sample-, design-, full-, minor-, and flexible customization. The supplier has written procedures and records for service assessment, corrective actions, and complaint handling. Its export sales share is stated at 71%–90%, with three years of export experience. However, the supplier has nine employees, only two years of total R&D engineer experience, no new products in the past year, no ODM, SDK, or overseas service infrastructure, and no stated customer cases. Audit information is provided for a TUV Rheinland audit with a validity period from September 4, 2025 to September 3, 2026, but the evaluation result is recorded as 0 and no certification name is specified.
Supplier typeThe supplier explicitly identifies as a professional technical supplier and a limited company. Its stated business and product scope covers mechanical parts, hardware products, metal tools, CNC machine tools, functional components, forgings, and powder metallurgy products; the audit record identifies mechanical parts as the primary product.
After-Sales capabilityThe supplier has clear written procedures and followed records for corrective and preventive actions and for handling customer complaints. This directly supports an established service-response process, although the slices do not provide service performance results or response-time data.
Production capacityThe supplier reports an annual production output range, six to ten quality-control staff, on-time delivery, random production quality inspection, and its own factory. It has nine total employees, so the available evidence supports an operating production capability, while capacity beyond the stated output range cannot be determined.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, and also welcomes OEM and ODM requests according to its company description. These repeated statements provide direct evidence of broad customization coverage, although the separate record states that ODM is not available, creating a conflict on ODM specifically.
Product Q&A
Q:What is a Scaffolding Swivel Coupler?
A:
A Scaffolding Swivel Coupler (also called a Swivel Clamp or Right-Angle Coupler) is a key forged steel fitting used to connect two scaffold tubes (pipes) at any angle. Its unique pivoting design allows the two jaws to rotate independently, enabling secure, non-parallel connections essential for building rigid three-dimensional scaffolding structures.
Q:What materials are your swivel couplers made from?
A:
We manufacture them from premium materials for maximum safety and durability: Body: Drop-Forged Carbon Steel (Grade Q235B or equivalent S235JR) with superior grain structure and impact resistance. Bolts, Nuts & Washers: Grade 8.8 High-Tensile Steel, hot-dip galvanized. Standard Finish: Hot-Dip Galvanizing (HDG) to ISO 1461 / ASTM A153 for maximum corrosion resistance.
Q:How can I request a quotation or sample?
A:
For a fast and accurate quote, please provide: Product Name/Standard (e.g., Swivel Coupler for 48.3mm tube to BS EN 74-1), Required Quantity, Destination Country/Port, and Any special requirements (custom marking, packaging).
Q:What scaffold tube sizes are they compatible with?
A:
Our standard couplers are designed for the global industry standard tube: Nominal Bore: 1-1/2 inch (1.5'), Outer Diameter (OD): 48.3mm. Other Sizes: Available for 42mm OD, 60.3mm OD (2-inch), and other specifications upon request.
Q:How is it installed and tightened correctly?
A:
Proper installation is critical for structural integrity: Place the two scaffold tubes into the jaws of the coupler. Ensure the coupler sits squarely with no gaps at the heel. Hand-tighten the single high-tensile bolt and nut. Final tighten using a scaffolding spanner (wrench) to the recommended torque (~40-50 Nm). Overtightening can damage the coupler or tube.
