プログレスAN Company Profile

We propose a comfortable living environment with our 'waterproof grating' that protects residential buildings from rainwater.

Since the development of our waterproof grille in 1990, we have been striving for better product development by incorporating the voices of many customers. Without being constrained by the traditional role of grilles for ventilation purposes, we will continue to develop products with the desire to create grilles that many people want.
