Embodiment of "the functional beauty of invisibility" that emphasizes visibility, transparency, and design!
The stainless steel hollow frame "Libraid" for glass fronts is a product that embodies the functional beauty of "invisibility," emphasizing visibility, transparency, and design. Through revolutionary roll forming, it achieves a weight reduction of approximately 40% compared to conventional flat bar frames (FB frames). This lightweight design significantly reduces the burden during construction. It accommodates large openings with a height of 6 meters and an infinite width. The visible width is our smallest at 6 mm. Even in the invisible parts, the beauty of stainless steel is highlighted in a thin and sharp manner.
