Metal Expansion Joints

Best Practices for storing Metal Expansion Joints for long periods

Improper storage of metal expansion joints for long periods can result in their deterioration over time, potentially causing corrosion of metal components and a reduction in overall reliability. To mitigate these risks, it is vital to adhere to recommended storage practices, ensuring their extended lifespan and averting potential complications.

This section provides guidance on how to keep metal expansion joints in good operational condition when they are stored for extended periods.

For the prolonged storage of metal expansion joints, it is imperative to inform MACOGA and request specialized packaging designed for long-term preservation.

When faced with challenging environmental conditions, it is advisable to contact MACOGA to explore custom packaging solutions.

Guidelines for prolonged storage

1. Do not remove the Expansion Joints from its original packaging until you are ready to install

2. Storage Area. Optimal storage conditions involve using a warehouse or a covered well ventilated dry area. Indoor storage is recommended.

3. Outdoor storage. Outdoor storage is not recommended for extended periods of time. If outdoor storage becomes necessary, it is imperative to place the expansion joints exclusively on wooden platforms, ensuring they remain entirely isolated from direct contact with the ground. In addition, it's essential to employ water protection measures, such as a tarpaulin. Please be aware that storing the joints outdoors for extended periods of time can result in premature deterioration.

4. The Expansion Joints should be reasonably protected from any accidental impacts

5. Do not stack anything (i.e. other expansion joints, other equipment, etc.) on the expansion joint boxes, pallets, etc.

Periodical Check

Regularly inspect the stored expansion joints to ensure they remain in good condition. Check for any signs of damage, deformation, or deterioration.


When the Expansion Joints are removed from storage, check for corrosion or damage.
