Project Background

About This Project

Meichen Steel Structures Co., Ltd. supplied and fabricated approximately 3,000 tons of steel structures for the Xinjiang Huineng Coal Chemical Project. The steel products were primarily used to construct pipe rack systems across the project area, providing reliable support for complex piping networks. Throughout the project, we ensured high structural stability, compliance with safety standards, and efficient installation, demonstrating our capability to deliver large-scale, customized steel structure solutions for industrial projects.

Standards & Delivery

Quality Assurance to Final Delivery

Quality Control

Material traceability was maintained according to project requirements. Raw materials were inspected before production, and welding and surface treatment were checked after fabrication. Third-party inspection was arranged when required to support compliance with project quality requirements and EN standards.

Surface Treatment

Surface derusting: The minimum surface preparation grade shall be Sa 2.5 for frame columns and beams, bracing members, and equipment beams. Coating System: Two coats of epoxy zinc-rich primer, with a minimum dry film thickness of 70 μm; one coat of epoxy micaceous iron oxide intermediate paint, with a minimum dry film thickness of 60 μm; and two coats of acrylic polyurethane topcoat, with a minimum dry film thickness of 70 μm. The resulting total dry film thickness shall be 200 μm.

Packing & Delivery

During packing, each steel component was clearly marked for identification to facilitate installation at site. Timber supports and protective spacers were applied at bundling points to protect the painted surfaces from damage during handling and transportation.
