Not fire-resistant steel steel heat when the temperature below 150 ℃ Guilin steel, steel nature changes very little. Therefore suitable for hot steel plant, but the heat radiating structure of the surface by about 150 ℃, to be used to protect the thermal shields. Temperature steel strength and elastic modulus decreased significantly at 300 ℃ -400 ℃, the temperature is about 600 ℃ Qinzhou steel, the strength of steel tends to zero. With special needs in the fire building, steel refractories must be protected in order to improve the fire resistance rating. How much Liuzhou Steel steel construction, marking an economic strength and economic well-developed country or a region degree. After entering 2000, a significant increase of the national economy, national strength, steel production has become a world power, proposed to "positive, rational steel" in the building, from the get rid of the "limit of steel" shackles, steel building in economically developed areas gradually increased. Steel Liuzhou, Guangxi Galaxy (certified), steel supplied by Guangxi Galaxy Metal Structure Engineering Limited. Guangxi Galaxy Metal Structure Engineering Co., Ltd. (www.gxmmr.cn) Guangxi Nanning, the activities of the leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
