They provide hard-to-damage, rust-proof, straight corners, which are easily curved for smooth arches. The solid PVC nose provides a straight, rigid, ground for screeding.
Vinyl is impervious to corrosion when coated in wet joint compounds, veneer plaster, or when placed in contact with steel or aluminum frames and resists impacts, dents, and damage during construction. No priming is required to add paint to vinyl products due to its paint adhesion properties. Vinyl has low electrical and thermal conductivity and is considered an excellent insulator, as well as being self-extinguishing and offering better resistance to burning than many other common building materials. Additionally, vinyl has a lower cost than equivalent products manufactured from zinc or aluminum, for use when the highest levels of corrosion resistance are required.
