Steel is nonflammable, but no fire. When the temperature over 300 ° C, the yield point, tensile strength and elastic modulus are began to drop significantly, almost to zero to 600 ° C. Common fire prevention measures is bread or brick masonry, concrete outside the steel structure can also be used in the component surface spraying a layer of vermiculite, asbestos cement or other material. When the surface of the steel structure long-term exposure to radiation more than 150 ° C, application of thermal insulation to protect it.
