The copper sheet is hammered with Kikukawa's proprietary technology and finished with a coat of clear coating. This finish recreates the classic and luxurious aesthetics of the traditional hammered handcraft finish.

This finish is suitable for signs, frames, ornaments or places that require architectural accents.

Maximum available thickness is 3.0mm, and 1000mm(W) x 2500mm(L) in size.

You could mix and max the material, hammering pattern and finish as required.
*This finish is part of the Tsuchime (hammered) sample book.

The metal sheets are hammered with Kikukawa's proprietary technology. By spacing the hammering pattern, the texture takes on a different aesthetic.

The spacing of the hammering pattern can be varied as required.

This Tsuchime selection features a copper piece hammered with a larger die, and a brass piece hammered with a regular sized die.

Maximum available thickness is 3.0mm, and 1000mm(W) x 2500mm(L) in size.

Material, hammering pattern and the coat finish can be mix and matched.

This striped Tsuchime, a Kikukawa original, is fabricated with Kikukawa's proprietary technology. The striped texture creates a stately atmoshpere that is emphasized with a Furumi (sulfurized) finish.

The Tsuchime selection features two copper pieces hammered with varying sized dies and spacing. One is finished with Furumi (sulfurized) finish while the other is mirror polished.

Maximum available thickness is 3.0mm, and 1000mm(W) x 2500mm(L) in size.

Hairline finish and glossy clear lacquer coating are applied to the copper alloy. This is an elegant finish that enhances the beauty of the material and is suitable for both interior and exterior products.

KIKUKAWA provides a variety of clear coating to suit the gloss level required for the project or the application area.

Hairline finish and a coat of glossy clear lacquer coating are applied to the copper alloy then polished by hand. The high sheen from the polished clear coating enhances the beauty of the reflective material, creating a luxurious ambiance. The gloss level could be adjusted by repeating the polishing process on the clear coating.

This finish is suitable for signs, ornaments or for any products to add an architectural accent.
The finish is applicable for other copper alloys; however the clear coating is only available in urethane.

A defined multi-directional finish and glossy clear coating are applied to the copper alloy. The vibration finish enhances the shiny surface of the copper alloy as the reflection is diffused.

This finish could be applied to ornaments, panels or doors as well as interior and exterior products.

KIKUKAWA provides a variety of clear coating to suit the gloss level required for the project or the application area.

The copper alloys with HL (hairline) finish are treated with dry FURUMI (sulfurized) finish then clear coated.

Sulfurization is a technique that recreates the rich brown hues of patinated copper alloy surfaces that would usually take decades to form. The artificial aging allows for the creation of a calming and luxurious space.

The effect of the sulfurization process is highly dependent on ambient conditions (such as the weather or the humidity) as well as the chemical composition or the lot of the material. Therefore, please contact us prior to making the final selection.

This finish could be applied to ornaments, panels or doors as well as interior and exterior products and is especially popular for religious architecture for the stately, rich ambiance.

The surface of the copper alloys are roughened through KIKUKAWA’s proprietary technology, treated with dry FURUMI (sulfurized) finish then clear coated. The colour variation from the material creates varying shades of patination that contributes to the ambiance of the project.

This finish could be applied to ornaments, panels or doors as well as interior and exterior products and is especially popular for historic or religious architecture for its stately, rich ambiance.

The surface of the copper alloy is treated then coated with FURUMI (sulfurized) finish, then pre-weathered to actualize the blue-green patination on the surface. As this blue-green physique is the final stage of copper patination that would otherwise take decades, the finish is especially popular for projects that seek a stately traditional physique.

The turquoise patina, also known as “verdigris”, provides a unique architectural accent to any project.
The colour of the verdigris and its development is project dependant; therefore please contact us prior to making the final selection.

Copper alloy sheets are hammered using specialized machinery, mirror polished then clear coated. The textural pattern recreates the traditionally hammered metal-craft by an experienced artisan.

This finish is suitable for ornaments or in places requiring architectural accents.

To ensure the quality of the material, please note that the available material size is limited as follows:
　Thickness (mm): ~2
　Size (mm): W220 x H1100

The surface of the copper alloy is embossed using KIKUKAWA’s Rough-tone Metal Series, KU-P170 (2φ), treated with FURUMI (sulfurized) finish then clear coated.

The consistent timeless pattern along with FURUMI (sulfurized) finish provides a unique and classis aesthetic that makes it suitable for ornaments or in places requiring architectural accents.

This finish is suitable for ornaments or in places requiring architectural accents.

This finish is applicable for other materials or finishes as long as the material thickness is less than 2mm. For other embossed patterns or information, please contact us.
