We offer cutting, welding, laser, and other processing services. Because our craftsmen perform the processing by hand, we are able to handle one-of-a-kind products and more. We mainly produce miscellaneous goods, furniture, fittings, and fixtures.


Powder coating is applied to metal products. Powder coating is a method of applying paint by electrostatically attaching powder and baking it to the surface to dry, and is environmentally and physically friendly and more durable than conventional solvent-based coating.


We mainly produce miscellaneous goods, furniture and fixtures. We also make one-of-a-kind furniture by processing unique one-of-a-kind pieces of wood.
