How to improve the open-air steel storage?

Utilizing the protective retractable canopy, the steel can be shielded from sun and rain, preventing rust and deformation. Furthermore, after being placed on the retractable cantilever shelves, the steel can be categorized and stored in designated locations. The shelves' high-load capacity and multi-position design can accommodate up to 10+ types of steel, with storage capacity ranging from dozens to hundreds of tons. The steel can be lifted or retrieved using cranes, with materials up to 50 meters in length being properly managed and stored.
