Color Steel Features And Main Units Jun 19, 2017

   Basic features: 1. Light weight: 10-14 kg / square meter, equivalent to 1 / 30.2 of the brick wall. Insulation: Core thermal conductivity: λ <= 0.041w / mk. 3. High strength: can be used for smallpox envelope structure bearing, bending compression; general housing without beams and columns. 4. Bright color: no surface decoration, color galvanized steel coating to maintain a period of 10-15 years. 5. Flexible installation: the construction period can be shortened by more than 40%. 6. Oxygen index: (OI) 32.0 (provincial fire product quality inspection station).Color Steel

    The substrate of the color steel plate is a cold-rolled substrate, a hot-dip galvanizing substrate, and an electro-galvanized substrate. Coating types can be divided into polyester, silicon modified polyester, polyvinylidene fluoride and plastic sol. The surface condition of the color steel plate can be divided into coated board, embossed plate and printing plate. The color steel plate is widely used in the construction of household appliances and transportation industry. The construction industry is mainly used for steel industry, airport, warehouse and freezing industry. Commercial buildings of the roof walls and doors, etc., civil buildings using less color plate. And steel difference between it and steel is different from the composition of the material, suction stone can be sucked. Strictly speaking, steel and Caigang in the metal properties and surface treatment is not a good distinction, because the same; so the distinction between the market mainly in the profile structure. Because it is an ordinary carbon steel material, the magnets can suck.

    In the late 80s of last century, China was only to build color steel plate units, these units were built in steel mills and joint ventures, color steel plate technology equipment imported from abroad. To 2000 domestic color steel plate reached 1.73 million tons, there have been overcapacity. State-owned large iron and steel enterprises of the unit capacity, equipment, a higher level, have been built with foreign technology, the annual production capacity of 120,000 to 170,000 tons of color plate unit.Color Steel

At the same time, many private enterprises to invest in color steel production mostly use of domestic equipment, production capacity is small, but launched quickly, low investment, the main products for building materials, decoration industry. In addition, foreign investment, Taiwan-funded also have landed to build color coating units, but most concentrated in the coastal areas. Since 1999, with the color coated plate market boom, color coated plate production and consumption has entered a rapid growth period. From 2000 to 2004, production increased at an average rate of 39.0%. By 2005, the national color coated board production capacity is greater than 8 million tons / year, there are a group of color coating units are under construction, the total capacity of more than 9 million tons / year.Color Steel
