Die Cast Aluminium Louver Outdoor Testing

Casting Aluminium External Louver - CAEL
We do a outdoor test from 25th of Dec., 2017 to 9th of Mar., 2018.
For the CAEL casting louver, our major difference from the others in the market is the finish, in order to prevent it getting rusty or oxidation, we have put on an extra powder coating on its surface which makes it being of higher quality and nicer finish, below is our test report.
