The warehouse steel structure project in Texas, USA, used only ASTM A36 carbon steel from Jinggong. Its mechanical properties are stable, the material certification documents are complete, and the project supervisor approved it on the first attempt, saving us significant time and costs.

"The outdoor scaffolding systems of power plants along the Southeast Asian coast are exposed to high salt spray environments year-round. Jinggong's galvanized steel has a uniform and dense coating, and its salt spray test results far exceeded expectations. After three years of inspections, no red rust was found on any of the substrates, demonstrating its convincing corrosion resistance."

"Our heavy mining machinery frames require extremely high-strength steel. Jinggong supplies S355J2 steel according to the European standard EN 10025-2, which has excellent impact toughness and performs robustly under extreme loads, greatly improving equipment safety."

"Before cooperating with Jinggong, we were worried about whether Chinese steel could consistently meet JIS standards. In fact, every batch of SPHC cold-rolled coils they provided had chemical composition and mechanical property data that were completely consistent with the certificate. This rigor gave us complete peace of mind."

"Our newly built logistics warehouse in Canada uses PPGI from Jinggong for both the roof and wall panels. The product not only meets CSA standards, but its unique weather-resistant coating design also allows the building to maintain its excellent appearance and performance under extreme cold and sun exposure."

"From the initial carbon steel trial order to the current comprehensive cooperation on stainless steel, galvanized steel, and color-coated steel sheets, Jinggong has proven its strength with consistently stable quality and professional service. They are not only suppliers of materials, but also our reliable partners in solving material technology problems."
