Development of Hainan Steel

Hainan Steel News: Development

Although China has a remarkable achievement in the early iron structure, but long-term stay in the horizontal iron buildings. Until the 19th century, China began using modern steel structure. After the founding of new China, the application of steel structure has been greatly developed, both in quantity and quality, or far more than in the past. Light steel floor by a cold-formed steel or composite beam, floor OSB structural panels, supports, connectors and other components. The materials used are OSB, cement fiberboard, and plywood. In these lightweight floor surface can withstand the load of 316 to 365 kilograms per square meter.

Hainan how much steel building, economic strength and economic marking a country or a region's level of development. After the year 2000, China's national economy, significant growth, national strength, steel production has become a world power, raised the need to "actively, reasonably steel" in the building, from the get rid of the "limit of steel" of the constraints, steel building in economically developed areas gradually increased. Especially after 2008, under the impetus of the Olympics, there has been steel construction boom, strong market demand, and promote the rapid development of steel construction, built a large number of steel stadiums, airports, railway stations and high-rise buildings, where some steel building a world-class level, such as the Olympic Games in the national Stadium construction production and installation technology.
After the Olympics, the popularity of steel construction and sustainable development, steel structure widely applied to construction, railways, bridges and housing, etc., thousands of steel companies of all sizes, the world's most advanced steel processing equipment substantially complete, as long drilling multidimensional, multi-dimensional intersection Cutting steel pipe, corrugated board automatic welding machine tools. And now manufacture horizontal steel companies hundreds of the world's advanced level, such as steel production and a premium enterprise. In recent years, steel production up to more than 600 million tons per year, steel products can meet the construction needs. Design of steel structures, steel material standards, steel construction quality acceptance, as well as various professional standards and corporate engineering methods basically complete.
Steel industry downstream development of steel industry has great traction and driving action, which directly determines the changing needs of the future development of the industry.
1. steel and other raw materials for the steel industry, the upstream supply sector
Iron and steel industry is the material basis for the development of the steel industry, steel industry technological advances for application of steel structure to create favorable conditions. The domestic steel industry, some large companies have begun research and development of varieties of steel structures and technology, have developed a high-strength steel and fire-resistant, weathering, seawater, anti lamellar tearing resistance at low temperature steel and H-beam, high performance colored steel, cold-formed steel, etc., for the development of steel industry has laid a good foundation for the application.
2, the downstream effects on the industry
Upstream steel is mainly the steel industry, steel products price fluctuations directly affect the procurement costs of the industry. Overall, the upstream industry basically is a competitive industry, the production of various types of steel used in steel, steel pipe, steel and other steel products, including H-shaped steel plate and steel building is the most commonly used products. Industry Insights research data in 2011 crude steel output reached 696 million tons, production is relatively saturated, steel production raw materials needed to obtain a stable supply.
Downstream industry development of steel industry has great traction and driving action, which directly determines the changing needs of the future development of the industry. Steel for its high strength, light weight, good seismic performance, high degree of industrialization, short construction period, plasticity, environmental protection and other comprehensive advantages, in industrial plants, municipal infrastructure, Sporting construction, electricity, bridges, offshore oil engineering, aerospace and other industries has been widely used, and gradually expand the market space. In addition, once the residential steel market breakthrough, and gradually replace the traditional architectural forms to enter the field of residential construction, steel industry will lead to explosive growth.

Wall structure is composed of roof trusses, OSB structural panels, waterproof layer, light roof tile (metal or asphalt shingles) and associated connecting member thereof. Matt light steel roof construction, appearance can be a variety of combinations. There are also a variety of materials. Under the protection of the waterproof premise of this technology, with the appearance of many options.
Light steel structure housing wall consists of wall studs, beams top of the wall, a bottom wall beams, supporting walls, wall panels and connectors components. Construction of light steel structure housing generally within the transverse wall as a structural load-bearing walls, light steel wall studs for the C-shaped member having a wall thickness according suffered load, and generally 0.84 to 2 mm, wall and column spacing is generally 400 ~ 600 mm, light steel structure residential building wall structure of this arrangement, which can effectively withstand the vertical load and reliable delivery, and convenient arrangement, but Matt light steel structure residential building wall structure can not withstand horizontal loads.
