The storage time for prefabricated beams should be determined based on specific circumstances; generally, it should not exceed 90 days. Extended storage may damage the surface protective layer of the beams, increase the risk of reinforcement corrosion, and affect the beam's strength and durability. Additionally, long-term storage may lead to erosion of the prefabricated beams by moisture and contaminants, impacting their performance. Therefore, to ensure the quality and safety of prefabricated beams, it is recommended to install and use them within 90 days whenever possible.

Storage Method and Requirements for Pre-fabricated Beams:

1) Flat storage is recommended; for items that can be stacked, the number of layers should not exceed 3.

2) Use sleepers (or square timbers) as support blocks. The support blocks should be placed below the suspension points (single-layer storage) or on the outside below the suspension points (multi-layer storage).

Three) The spacing between two sleepers (or squared timbers) should not be less than half the stacking height.

4) The relative positions of each layer of sleepers (or timbers) should be aligned on a single vertical line.
