Hello,
Our sliders are made of zinc, they are very resistant to wear and different climates.
However, when using the wrong tools or forcing too much to install them (for example, if the size is too small and you force it), it can indeed damage the slider. Especially small sliders because the smaller an item is, the more fragile it will be and it should be handled with care.
That is why we recommend every customer who needs help with installation or choosing their product to call us or send us photos by email of the zipper to be repaired.
We can guide you to the right products and we can also guide you step by step for installing a slider.
We also have many articles on the site, especially on the blog, with images and videos that can help you better understand how to install the slider.
Do not hesitate to contact us if needed:

Best regards
