GALVALUME steel sheet combines the merits of galvanized steel sheet and aluminized steel sheet
The plating consists of 55% aluminum, 43.4% zinc and 1.6% silicon. By adding the galvanization (galvanic protection) of zinc to the long-term durability and heat resistance of aluminum, a Galvalume steel sheet has a durability of about three to six times longer than galvanized steel (270 g/m2 both) under various conditions of use.
Allows application of very low carbon grades (up to maximum of 0.10% carbon), including vacuum degassed & interstitial-free steels.
CS Type B
Specified to avoid carbon levels below 0.02%. Carbon range is 0.02 to 0.15%. This describes the typical ASTMCQ of the past.
CS Type C
Allows application of very low carbon grades (up to a maximum of 0.08% carbon). Also allows higher phosphorus (0.10 max) levels.

Product Advantage of Z275 galvalume steel sheet
Coated steel sheet for a new age - economical, featuring excellent corrosion resistance, heat resistance, heat reflectance, and workability.
Excellent long term durability
GALVALUME steel sheet does not readily lose its beauty even when exposed to the elements for long periods of time and has been proven to be three to six times more durable than galvanized steel (270 g/m2 both) under various conditions of use. Its durability is particularly demonstrated in coastal areas and harsh environments of industrial zones. Eco-friendly material
GALVALUME steel sheet is coated with a special film by special treatment that contains absolutely no chromate.
Good heat resistance
GALVALUME steel sheet has a heat resistance similar to aluminized steel sheet because of the high aluminum content: 55% mass ratio and 80% volumetric ratio.
Coupled with its good heat reflectance, the effect is well exhibited with toaster ovens, rice cookers, etc. Good heat reflectance
The surface reflectance of GALVALUME steel sheet is high, it is very effective for preventing indoor temperature rises in roof applications, as surface temperature rises minimally. Smooth shiny surface
The silver surface has a unique delicate spangle that is highly appreciated when used as a building material.
Same workability and paintability as galvanized steel GALVALUME steel sheet can be worked and painted afterwards just like galvanized steel sheet.
Carbon steel, also known as carbon steel, refers to iron-carbon alloy with carbon content Wc less than 2.11%. Generally, it is used after normalizing or quenching.

ASTM A284 Carbon Steel Coils is used as parts requiring higher strength and wear resistance or less elasticity, dynamic load and impact load, such as gears, rims, flat springs, crankshafts, etc., and can also be used as castings.
