The SLEEK 146 series minimalist sliding door stands as the flagship premium sliding door system of SLEEK, with a proven track record of successful large-scale architectural projects spanning across luxury residential villas, high-end commercial buildings, and modern minimalist developments worldwide. This minimalist sliding door system offers over two hundred distinct profile configurations, engineered to address the most complex architectural sliding door challenges, from expansive facade openings to seamless indoor-outdoor transitions.

Designed for uncompromising aesthetics and performance, the SLEEK 146 series ultra-slim sliding door features a 39mm glass groove, perfectly compatible with insulated glass, laminated insulated glass, and multi-layered glass options to meet diverse thermal and acoustic insulation requirements. It provides flexible track solutions, including exposed and concealed track designs, with the added option of electric opening for enhanced convenience and smart home integration, solidifying its position as a leading premium sliding door system.

At the core of its robust performance is the precision roller bearing pulley design, which delivers reliable technical assurance for large panel sliding door applications—supporting single sliding panels up to 3m x 6m (customizable in width and height) with a maximum weight capacity of one ton. The four-sided concealed frame design achieves an ultra-slim visible hook edge of just 20.9mm, maximizing natural light and panoramic views while maintaining structural integrity. For regions with strong winds or ultra-high panel installations, the inner groove of the hook edge can be reinforced with a stainless steel lining, further elevating the durability and wind resistance of this exceptional ultra-slim sliding door.
