Glass canopies are usually attached using specialized fastening systems that provide a safe and secure structure. Some common attachment methods include the use of concealed metal brackets or fastening strips that are secured to the wall of the building. These fasteners are usually made of stainless steel or other materials that are strong and resistant to corrosion. Fixing the plane of the canopy to the brackets can be done with the help of special glass holders or other fasteners designed to securely fix the glass.
