C5 Epoxy-Coated Heavy Frameworks for Nickel Smelter in Indonesia
To be confirmed
Project Overview
As the world's largest producer of laterite nickel ore, Indonesia is in the midst of a new energy smelting construction boom. However, smelting plants face not only the high heat and humidity of the tropical rainforest but also highly destructive acidic and alkaline chemical corrosive gases internally. The EPC contractor urgently needed heavy steel frameworks with extreme anti-corrosion performance and absolute material safety backing. Shijie Heavy Industry meticulously applied a flawless C5 epoxy coating system and submitted 100% MTR traceability and UT testing reports, instantly winning over the highly critical on-site QA/QC inspection team.

Constructing our nickel smelter is a constant battle against harsh elements—we face severe tropical humidity mixed with highly aggressive chemical fumes from the smelting process. It demanded heavy frameworks with superior, uncompromised corrosion resistance. Shijie Heavy Industry stepped up and applied a flawless C5 epoxy coating system that looked and performed exactly to spec. But what truly sets them apart as an elite supplier is their paperwork. Their 100% MTR traceability mapping and the detailed UT reports for all full-penetration welds were so thorough that they passed our notoriously strict QA/QC team instantly. No delays, no arguments, just solid engineering.
