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 Truck Trailer Door Lock Latch?
A:
A Truck Trailer Door Lock Latch is a heavy-duty, security-critical hardware mechanism installed on the rear or side doors of freight trailers, shipping containers, and truck bodies. Its primary function is to securely lock the doors in the closed position during transit, preventing unauthorized access and ensuring cargo safety.
Q:What types of lock latches do you manufacture?
A:
We produce a comprehensive range for various trailer types and door styles: Swing Door Latches, Roll-up Door Latches, Lock Rod Assemblies, High-Security Locks, ISO Container Door Locks, and Replacement Parts.
Q:What materials are used for durability?
A:
We use robust materials including Hot-Forged or Cast Steel (A36 or higher), Stainless Steel (304/316), Hardened Steel for locking bolts, and Stainless Steel springs. Finish is typically Hot-Dip Galvanized, with Powder coating and Zinc plating also available.
Q:What is the difference between a cam lock and a paddle handle latch?
A:
Cam Lock is a rotating, hook-shaped bolt operated by a key, providing a simple lock. Paddle Handle Latch is a long lever handle connected to internal lock rods, offering mechanical advantage for pulling doors tightly shut and often incorporating a keyed lock.
Q:How do I get a quote or technical support?
A:
For a fast and accurate quote, please send photos and dimensions of your current latch or door, required quantity, keying preferences (KA, KD, MK), and any special security or finish requirements.
