ED coating agreement signed with Shinto Toa Vietnam

An agreement signed in Hanoi on 2 December brings electrodeposition coating to the premium profile range — a bath process that reaches the inside of a hollow section, which a spray line does not.

An agreement signed in Hanoi on 2 December 2025 with Shinto Toa Vietnam brings electrodeposition coating to the premium profile range.

ED is a bath process, not a spray one. The section is immersed and the coating is drawn to it electrically, so it builds evenly on faces a gun cannot see: the inside of a hollow, the back of a return, the root of a groove. On an architectural section those are exactly the surfaces that start corroding first, because they are the ones that stay wet.

What that buys, in order of how much it matters on site: corrosion and oxidation resistance across the whole section; colour that holds because film thickness is even rather than heavy on the front and thin at the edges; adhesion that survives fabrication after coating; and a smoother finished face.

The two sides have set out a longer programme — new premium sections built around the process, a standardised production sequence, and further sections to follow.
