[Strength of products/technologies]
We developed a waterproof louver (aluminum louver door with good waterproofing performance) with the cooperation of Kumamoto University and Kumamoto Industrial Research Institute. This is our main product line among our original products for its high waterproofing and ventilation performance.
We are also expanding our external louvers with equal ventilation and viewing obstruction developed to meet the needs of design offices and general contractors. We can flexibly develop small-lot and special products that are difficult for major manufacturers to handle.


[Representative's message]
Our company was founded in 1964. We have been devoted to designing, manufacturing, and installing sashes.
