Profile

The manufacture of steel fittings such as large doors and special doors and the construction business

We are a pioneer in large doors and special doors, doors used in hangars for large aircraft, and doors used for other special purposes.

All of our products are made-to-order. No two are the same. Our larger products have a width greater than 100 m; however, even changing the size of similar doors by as little as 2 m would require the material used in the skeleton to be changed. Therefore, we create doors by hand to deliver each client. We strive to deliver what meets our customers' requirements every time.
Thankfully, recently, overseas orders and orders for big projects have increased for products such as the Folio Updoor, which is our own original product, and which was installed in Narita Airport departure terminal during its recent renewal work.
