Covertec SP profiles are designed to be bendable due to their shape, and hence there is not a specifically bendable version as there is for the Trimtec TR. The bendable characteristic of the Covertec SP profiles also depends on the material (steel, for example, is less flexible than brass). The profiles most suited to follow curves or special shapes are the Covertec SP14OL and Covertec SP14AS models.

The function of both Roundjolly profiles is that of protecting external wall corners by forming a rounded corner. In particular, Roundjolly RJE has a completely closed curve, and it’s more economical. The Roundjolly RJ, on the other hand, has a more open curve, which allows the adhesive to penetrate into the profile, guaranteeing a stronger installation. For this very reason Roundjolly RJ has more available finishes.
