Crafting Frames
That Endure
For over 25 years, Lanke Profiles has been at the forefront of architectural glazing systems, engineering window and door frames that meet the highest standards of performance, durability, and design.
Engineering Precision
Since Day One
PrimeFlex began as a small manufacturing unit in 1998, supplying aluminium window frames to residential builders in our home region. Our commitment to tight tolerances and repeatable quality earned us a reputation that grew faster than we anticipated.
By 2005, we had expanded into uPVC systems and composite frames, adding thermal break technology that significantly improved energy performance. Our product range grew from a handful of standard sizes to hundreds of configurable profiles.
Today, with distribution partners across 40+ countries and a dedicated R&D facility, PrimeFlex continues to push the boundaries of what's possible in architectural glazing — from hurricane-resistant coastal systems to ultra-thin minimalist profiles for modern architecture.
