Packaging

Our Flanges are mostly packaged in a wooden crate with cushioning material to prevent damage to the material during transportation and handling. Small pieces of titanium forgings are also well-packed in cartons.

Most sizes of flanges are not kept in stock and if you have a special request, please feel free to contact us here.
