Galvanized steel sheet is carbon steel sheet coated with zinc on two sides. the process used to do this is known as the continuous hot dip process. this process results in a layer of zinc which adheres tightly to the base steel and has a spangled, or snowflake-type, appearance. The layer of zinc acts as a sacrificial coating.
Galvanised steel is mild steel with a coating of zinc The zinc protects the steel by providing cathodic protection to the exposed steel, so should the surface be damaged the zinc will corrode in preference to the steel Galvanised steel is one of the most widely used products, used extensively in the building sector, automotive, agricultural and other areas where the steel needs to be protected from corrosion.

Export is a very important factor in the development of petrochemical general machinery industry. The current development of independent brands, optimizing the structure of export products, and improving export growth are major issues facing the industry. To this end, it has increased investment in the development of new products, developed products with independent intellectual property rights, attached great importance to the continuous improvement and improvement of product technology standards, strived to move closer to international advanced standards, and continuously improved the quality of export products. It has now become The consensus of petrochemical general machinery industry. At present, China has signed agreements or trade agreements with ASEAN, Chile, South Korea, India and other countries and regions. In 2007, the two sides should further reduce import tariffs, which provides an opportunity for the export of mechanical products in China.
It is understood that on September 14 last year, the Ministry of Finance and the Development and Reform Commission and other five departments jointly issued a notice to adjust the export tax rebate rate for some commodities from September 15 of that year. Among them, the petrochemical general machinery industry has 13 tax refunds for export tax products from 13% to 17%. The implementation of this policy has played a significant role in advancing the structural adjustment of the export products of the petrochemical general machinery industry and the improvement and upgrading of the industrial structure.
In addition, for the 16 major technical equipments identified by the country as key developments, relevant government departments are formulating relevant supporting measures and preferential tax policies to give appropriate support to the application of the first (set) major technical equipment made in China, and at the same time formulate and strengthen major technologies. The management methods for the repeated introduction of equipment do not, in principle, support the complete introduction of major technical equipment, but encourage the expansion of imports of key components, advanced technologies and equipment. On this basis, digestion and absorption will lead to the creation of self-centered Equipment manufacturing capabilities.
Hot-Dip Galvanizing or HDG is a process in which zinc bonds to steel at the molecular level to produce a four-layer corrosion-resistant finish. The first three layers are zinc-iron alloy layers that are actually harder than the base steel. The fourth or top layer is pure zinc.
Customs statistics: petrochemical general machinery import and export trade surplus for two consecutive years
According to customs statistics, in 2006 China's petrochemical general machinery industry imported and exported a total of 40.43 billion US dollars, an increase of 25.48% over the previous year; of which imports 17.162 billion US dollars, an increase of 11.22% over the previous year, exports 23.268 billion US dollars, an increase of 38.6% over the previous year. After the import and export of petrochemical general machinery industry realized its surplus for the first time since 2005, the surplus in 2006 reached 6.105 billion U.S. dollars, an increase of 4.748 billion U.S. dollars over the previous year. Despite this, at present, the industry's imports and exports are still facing three major problems. One is to expand the export of self-owned brands, the other is to make good use of the adjustment of export tax rebate policy, and the third is to expand the import of major equipment key parts.
