We offer vibrant and glossy colored anodized aluminum that is unique to our company.

We can process the following types of aluminum: A1000, A2000, A5000, A6000, and A7000. We adjust finishing specifications such as matting and gloss. We handle pre-processing such as masking, blasting, and buffing, and post-processing such as laser marking. 
Processing size is up to 500mm × 1,500mm × 750mm.
We support corporate branding with high-quality surface treatment
[Advantages of our products]
Anodized aluminum is a surface treatment used for various purposes, such as coloring aluminum for prevention of rust as well as decoration. Color variations of 17 colors of general colored anodized aluminum and 6 colors of hard-anodized aluminum contribute to added value for business partners and contribute to expanding market share. We are waiting for orders from precision part processing companies, manufacturers who want to increase color variations, and companies and manufacturers who want to enhance their brand power with high-quality surface treatment. We have the know-how of coloring anodized hard anodized aluminum and anodizing duralumin (A2017/A7075), which are generally considered unsuitable. We are trying to differentiate ourselves from other companies with our products. Our company is often requested to repair defective products made by other companies because of our extensive experience in re-anodizing.
