In addition, we have researched various materials for interior/exterior decorative building parts and developed applications for products, and we have welcomed our 47th year since establishment. Now, we are a general manufacturer of decorative building materials, and as the leading manufacturer of Japan in the industry, we are currently developing easy installation products that does not need highly trained skills.

Here are some of the exemplary products we have developed recently.

Incombustible artificial wood for interior:
The calcium silicate based ceramic material for the porous molded plate has excellent fire protection quality and certified by the Ministry of Land, Infrastructure and Transport as incombustible product in Japan. (Certificate numbers NM-2204, NM-2607) Because it is wrapped in a three-dimensional wave, it becomes a material that can be easily refined by the flow of air and moisture.We offer products with various purposes including molding, decorative wall panels with ribbed or wave patterns, and ceiling material.
Glass fiber reinforced gypsum product of incombustible material:
The gentle texture of the plaster gives a profound feeling to the space and has been well received by our customers. As its main component is fine powder without an aggregate, we can provide products that maximize fine design.

We are also developing a number of other products that combine the special features of the material with our proprietary technology. In addition, we are establishing a production system for "custom orders" that can be delivered with short lead time when ready-made products do not fit the planned building space. Mihashi will continue to make global contribution in the ornamental industry.
