Wuhan Hongxin Lixin Metal Products Co., Ltd. (Mali Steel Shot) has just returned from the 9th Changyuan Corrosion Control and Power Energy Industry Expo, held October 16-18 at the Changyuan International Convention and Exhibition Center. After three days of conversations with dozens of anti-corrosion contractors and purchasing managers, this year's purchasing behavior looks different from previous years, with three clear new trends.

Changyuan is China's best-known anti-corrosion hub: cumulative output of 56.7 billion RMB, more than 300 Class-1 qualified enterprises, and 1,290 construction companies. The expo drew 307 exhibitors, including nine listed companies such as Sany Heavy Industry, Hengtong Optic-Electric, Hempel, SKSHU, and CSSC Yangtze Technology.

Trend 1: From unit price to total cost

Buyers used to ask for the price per ton first. Now more owners calculate total cost.

The reason is simple: high-breakage shot powders halfway through blasting, so crews refill constantly and labor and downtime costs climb. Mali Steel Shot measures ≤0.8% breakage with 3000+ cycles.

One purchasing manager at Zhongzhou Construction ran the numbers: Mali Shot costs about 200 RMB more per ton, but total abrasive consumption drops 15% across a pipeline coating job — the total cost is actually lower.

Trend 2: From generic sizes to custom grading

Different anti-corrosion jobs need very different abrasive sizes, and the one-size-fits-all approach is being replaced.

• Large steel structure areas: S330 (0.8-1.0mm), high efficiency
• Pipe interiors and welds: S390 (1.0-1.2mm), strong penetration
• Heavy anti-corrosion and marine engineering: S460 (1.0-1.4mm) plus G25 steel grit, higher roughness

Mali Steel Shot keeps all sizes in stock across 28 warehouses.

Trend 3: From spot buying to annual framework agreements

Large-volume buyers are moving from scattered orders to annual framework agreements.

Customers using 500+ tons per year can sign annual framework agreements with locked pricing, drawing from 28 warehouses across Henan, Shandong, Jiangsu-Zhejiang-Shanghai, and Guangdong. Wuhan Hongxin Lixin has 26 years in steel abrasives, 100,000 tons annual capacity, 50 patents, and serves 3,000+ enterprises including 42 listed companies.

The show is over, but follow-up has just begun

About 15-20 enterprise contacts were added on site during the three days, and samples are being shipped one by one. Anti-corrosion contractors who need steel abrasives can request samples at any time.

Common questions

Q: Why are anti-corrosion contractors moving away from unit price?

A: High-breakage shot powders halfway through, so refills, labor, and downtime add up. Shot with ≤0.8% breakage and 3000+ cycles lowers total cost.

Q: What sizes suit different anti-corrosion jobs?

A: S330 for large steel structure areas; S390 for pipe interiors and welds; S460 plus G25 grit for heavy anti-corrosion and marine work.

Q: How should large-volume buyers purchase?

A: Annual framework agreements for 500+ tons per year lock pricing and draw from 28 warehouses.
