How must reinforcement steel be stored to avoid direct contact with the ground?

Reinforcement steel must be stored on pallets to avoid direct contact with the ground primarily to protect it from moisture and contaminants that can cause corrosion. Storing steel directly on the ground exposes it to soil moisture, which can initiate rusting and degradation of the material. By elevating the steel using pallets, it allows for better air circulation around the steel, reducing the chances of moisture retention and preventing contaminants such as dirt and debris from accumulating on the steel surface.

This method also facilitates easier handling and transportation of the steel, ensuring that it remains in good condition until it is needed for construction purposes. While moisture-proof containers can be beneficial, they are not a practical or standard method for storing reinforcement steel compared to the common practice of using pallets. Additionally, open-air storage may still allow for ground contact or moisture exposure depending on the conditions, thus reinforcing the importance of using pallets.
