Value Verification: Real-World Cases and Data

Case 1: Sany Heavy Machinery Co., Ltd. – Machinery Manufacturing Enterprise

Sany faced challenges with its previous supplier, where low cutting accuracy led to a 15% component rejection rate, and delivery delays extended production cycles by 10%. The company needed 304 stainless steel sheets custom-cut to precise dimensions for hydraulic components, which required tight dimensional tolerances of ±0.02mm.

Congbang provided a solution including custom cutting with ±0.01mm accuracy, accompanied by an SGS inspection report to verify material properties. The order was delivered within 5 working days, meeting the urgent production timeline.

The outcome was significant: component rejection rate dropped to 2%, production efficiency increased by 20%, and annual cost savings reached $1.2 million. Sany’s 2025 Supplier Evaluation Report noted a 95% repeat purchase rate for Congbang’s products, citing reliable quality and fast delivery as key reasons.

Case 2: China State Construction Steel Structure Co., Ltd. – Steel Structure Processing Enterprise

CSCEC’s on-site slitting and leveling of 304 stainless steel coils consumed 35% of labor resources, increasing production costs by 18% and delaying project completion by 12 days. The company sought a supplier that could provide pre-processed ready-to-use sheets to reduce on-site workload.

Congbang offered slitting and leveling services, delivering sheets cut to the exact dimensions required by CSCEC. The company also provided surface treatment to enhance corrosion resistance, ensuring the sheets could withstand outdoor construction environments.

As verified by CSCEC’s 2026 Project Efficiency Report, the project completion time was shortened by 10 days, enabling the company to meet its municipal construction deadline ahead of schedule. Labor costs were reduced by 35%, and the overall project cost was cut by 12%.

Case 3: Shanghai Orient International Trading Co., Ltd. – Export Trade Enterprise
