Dongguan, China – August 21, 2026

J And R Metalwork Industry Co., Ltd. (J&R Metal), a professional multi-category fastener export supplier, has further improved its in-house QA/QC inspection system to guarantee the consistency and stability of both standard parts and non-standard machined components for customers worldwide.

The upgraded quality control system covers every stage of production, from incoming raw material inspection, forming and machining processes, to surface treatment and full inspection of finished goods. Strict control points are implemented at each stage to ensure that every batch meets the required specifications and tolerances.

• Raw material incoming inspection – verification of material certificates, chemical composition and mechanical properties
• Forming and machining control – in-process dimensional checks during cold heading, threading and CNC machining
• Surface treatment – Dacromet, hot-dip galvanizing, blackening and nickel plating with coating thickness verification
• Full final inspection – comprehensive dimensional, thread and appearance checks before packing and shipment
