Keel is a kind of material commonly used in ceiling decoration.
Considering the perfection of the final effect, the paint keel and
aluminum alloy keel which play the role of bracket become the first
choice. It is also the keel. What is the difference between them? Let's
understand it together
The main raw material is iron, which is galvanized on the basis of iron to prevent rust.
Because the raw material of the painted keel is iron, it will rust, turn
yellow and lose paint after a long time due to oxidation, especially
can not be used in wet places. (the thickness of galvanizing determines
the time of rusting)
The main raw material of aluminum alloy keel is aluminum, and the
surface can be colored according to the demand, and evenly sprayed on
the aluminum material by powder spray coating, and the protective film
is formed after high temperature baking.
