Jointless Extra Large Dual Curved Monument
At Kikukawa, we fabricate jointless extra large dual curved monument from design to installation, using our expertise in metalwork.
Artworks and monuments tend to be required in small lots in a unique, complex shape. In realising these designed shapes, metals tend to be chosen for its high designability and workability. Especially artworks that are extra-large or complex in shape, or those that would be placed outside or in coastal areas, considerations to installation and fabrication methodology are required from the design stage.
Kikukawa has been providing solutions to such projects as metal construction experts. Spheres and double curved shapes, such as triple helixes, require highly-specialised metalworking know-how and technologies.
The following is such an example, a parabolic arch made with 4.5mm thick steel sheets with max. width at 852mm. The arch itself is 7355mm high and the food-width is 1783mm wide. In addition to the curve as an arch, the steel plate curves inwards, much like the shape of a tong.
The completed and installed monument
Due to its size, this monument was fabricated from 5 pieces. Each piece was bent and curved before it was welded together. The monument was finished and shipped as one-piece to maintain and ensure its quality.
The difficulties in fabricating these extra large double curved monuments are in fabrication, and in installation. At Kikukawa, the fabrication difficulties were overcome by combining expert craftsmanship and precise bending technologies. For shipping and installation, our experts planned carefully in advance for a smooth delivery.
Bending the pieces. Teamwork is of utmost importance to fabricate large products
Preparing the pieces for welding. The precision of this process decides the welding quality
Welding the pieces upright to maintain their shapes. Welding this way requires expertise
After welding the pieces, they are carefully re-finished, then prepared to prevent oxidation. The joint areas are indistinguishable on the final product that was painted in metallic grey.
Installation testing and inspection of the product
The monument is inspected and tested within our factory before shipment. In doing so, we refine our installation methodologies, leading to a smoother installation process onsite.
As shown above, Kikukawa provides design to installation services of extra large double curved monuments or artworks. By selecting the most suitable fabrication and installation methodology based on product shape, material or installation areas, we ensure the delivery of high-quality metal works.
