Key
Stones

Keystones are the culminating element of an arch. In architecture, they serve two purposes: ornamental and practical. Petra Design specializes in creating keystones for arches, doorways, and windows that guarantee structural integrity and give them sophisticated visual appeal. Keystones were once the central stone in arches that equally distributed weight, but they are now used as decorative accents in commercial and residential architecture. Petra Design provides a range of keystone styles, from traditional to contemporary, with detailed carvings or smooth, simple finishes, all of which can be tailored to a project's requirements. The keystones of Petra Design are built using long-lasting materials like GFRC, which ensures their strength and beauty over time. They are both practical and decorative elements that contribute to architectural depth and character, whether for modern, new construction, or historic repair.
