Why do metal roofing products get complained about?
The most common reasons for complaints include peeling paint and subsequent corrosion of the metal roofing. This problem can lead to aesthetic defects, reduced roof life and other technical complications.
The main causes of peeling paint and corrosion:
1. Improper storage conditions:
- If metal roofing products are stored for too long in an environment with high humidity or variable temperatures, condensation can occur. This leads to the separation of the protective paint layer and subsequent oxidation of the zinc layer.
- After the zinc protection is damaged, the steel core is exposed, which gradually corrodes.
2. Mechanical damage:
- Damage during transport or rough handling can cause microcracks that gradually enlarge and lead to peeling paint.
3. Improper installation:
- Incorrect installation techniques, such as using unsuitable screws or not sealing the joints properly, can also contribute to surface damage.
Why does white powder appear on metal roofing?
Customers often ask why white powder appears on the surface of the roofing when metal roofing is exposed to similar weather conditions as on a roof. The key difference is that on a roof, the metal dries quickly due to air flow and sunlight.
However, if the sheets are stored on top of each other and moisture accumulates between them, they do not have a chance to dry out. This process leads to the formation of a white powder known as **white rust**, which indicates oxidation of the zinc layer.
How to properly store metal roofing?
If the sheets need to be stored for more than three months, we recommend that you follow these guidelines:
1. Removing the protective film:
- Remove the film within two weeks of delivery to prevent damage to the surface from sunlight and moisture.
2. Protect from moisture and temperature fluctuations:
- Store the sheets in dry and ventilated areas away from direct sunlight and water.
3. Distance from the floor:
- The sheets should be stored at least 20 cm above the ground to prevent moisture absorption.
4. Use of spacers:
- For better air circulation, place thin pads between the individual sheets or place them vertically against a wall.
5. Short-term outdoor storage:
- If the sheets need to be stored outdoors for a short time, ensure that they slope to drain water and use the original packaging with sufficient ventilation.
