Product Description
Production Introduction
Galvalume steel is the plating coat of aluminum-zinc alloy armor plate,and its composition is 55% Al,43.3% Zn and 1.6% Si.The plate with smooth surface and excellent corrosion resistance of the atmosphere,which is 2 to 6 times higher than hot-dip galvanized sheet of the same thickness of coating.After through three processes,including payoff reel,crop shear and welding,enter into the continuous annealing furnace.During the annealing process,strips are heated closer to the recrystallizing temperature,and then heated to 20~50 above the recrystallizing temperature in the reducing furnace.After keeping the same temperature for 170s,strips are naturally cooled to the normal temperature in the slow cooling process.Afterward,strips enter into the ZN-AL pot through the elephant's trunk and begin in the hot-dip coating process.The optimum temperature range of the plating coat is 630-660ºC.Coated with aluminum-zinc alloy,strips enter into the cooling tower by the steady roll and air knife.After fast cooled with wind or water,they are directly produced into Al-Zn armor plates.The general rate of cooling 30/s or so,and strips are cooled to about 60.

Product Advantages
Continuous GalvanizationUsing techniques perfected by years of experience, Dingang Steel's hot-dip galvanized steel sheet is formed on a line that is continuously galvanizing to guarantee smooth, high quality end products.
Dingang Steel is committed to offering galvanized steel sheet with a broad range of base metal qualities, including commercial, lock forming, drawing, and structural quality. Moreover, each product undergoes a chromatic process for protection against rust.
Superior FormabilityHighly workable steel sheet and strips are used as base metals for all galvanized steel sheet produced at the Cold Rolling Facility of Dingang Steel. The base metals in coil are continuously annealed, galvanized, and properly leveled. The galvanized sheet provides superior formability with base metals.
Excellent Corrosion ResistanceAll galvanized steel sheet is treated with chromic acid for protection against rust, to maintain original surface luster for a longer period.
Consistent QualityProduction is carried out using a rigorous quality control process and a strict quality inspection based on high quality production standards. As a result, product quality, dimensions, and other properties strictly conform to customer demand.
