The galvalume steel sheet is
composed of aluminum-zinc alloy. It is composed of 55% aluminum, 43% zinc and
2% silicon solidified at 600 ℃. And its whole structure is composed of
aluminum-iron-zinc to form a kind of dense quaternary crystal alloy. Galvalume
steel coil is an important alloy metal that is often used in daily life.
Galvalume steel coil has many
excellent features such as strong corrosion resistance which is 3 times than
galvanized steel sheet. The surface has beautiful alum-zinc flower, can be used
as building outside panel.
The corrosion resistance
property of galvalume steel coil is mainly due to the aluminum component and the
aluminum’s protection. When the zinc is worn, aluminum forms a dense layer of
alumina in order to prevent further corrosion of the corrosive material.
Second is heat resistant
property. Galvalume steel coil has good heat resistance. It can bear more than
300 degrees Celsius high temperature which is similar to aluminum steel plate.
Galvalume steel sheet is often used in chimney tube, oven, lighting and
gluorescent shade.
Galvalume steel sheet has a
high thermal reflectivity that is twice that of a galvanized steel sheet and is
often used as base material for insulation products.
Because of the 55% density of AL-Zn is smaller than
the density of Zn, with the same weight and same zinc layer coating thickness at
the same circumstances, the galvalme steel sheet’s square is 3% bigger than galvanized
steel sheet.
Our high quality galvalume steel coil is mainly used
in construction, automobile, home appliances, agricultural, etc. If you would
