KETTLER® uses their top-of-the-line Electrotherm™ coating technology on all of their wrought furniture. The finish is three times thicker than a regular powder coat, creating a super smooth surface without those pesky weld points. Plus, it's extra durable and resists scratching, peeling, fading, and chipping. Best of all, it stays cooler to the touch (about twenty percent (20%) cooler!) after being out in the sun for a while. And don't worry about damaging your furniture with an umbrella - this table comes with an umbrella plug and sleeve to protect the finish and center your umbrella.
