Hainan Steel remind you: the influence of temperature on the steel structure installation

Effect of temperature on steel installation is obvious, and more complex. Steel linear expansion coefficient of 1.2 × 10-5m / m ℃. Usually the installation of high-rise steel go through the summer to the winter temperature in North China in winter and summer temperature can reach 40 ℃. If the largest steel contour size 100m, the expansion and contraction of the theoretical value reached 48mm. Currently, the project lay-off phenomenon often occurs midway, a long pause handover process would bring trouble, measurements at different ambient temperatures can be significant differences. Procedures should take into account the existing norms China's current project situation, the impact will be classified prescribed temperature difference. Hainan Steel
