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 the difference between Grade 80, Grade 100, and Grade 30/43?

Grade 30/43 is for general purpose/towing, NOT overhead lifting. Grade 80 is the standard for overhead lifting (heat-treated alloy). Grade 100 is high-performance, stronger than Grade 80, allowing lighter/smaller chains for the same load. We recommend Grade 80 and 100 for overhead lifting.

Q:How is the Working Load Limit (WLL) determined?

WLL = Minimum Breaking Force (MBF) / Safety Factor. Grade 80 uses a 4:1 safety factor; Grade 100 uses 4:1 or 5:1. WLL is derated based on sling angle. We provide comprehensive load charts and technical assistance.

Q:How do I select the correct chain size and configuration?

You need to know: Load weight, lifting angle (tension increases as angle decreases), hitch type (Basket, Choker, Vertical), and environment. We recommend consulting a qualified rigger or using our online WLL calculator. Our team can assist.

Q:How do I request a quote?

Please provide: Chain Grade (80 or 100) and Diameter, Sling Configuration and Length, Required WLL or load details, Type of end fittings, and any required certifications.

Q:How should lifting chains be inspected and maintained?

Daily visual inspection for wear, nicks, stretch, or corrosion is mandatory. Use a go/no-go gauge for link elongation. Clean and lubricate to prevent corrosion. Maintain an inspection log for each sling.
