style="text-indent:25px">鋼結構常用的幾種鋼材特性：熱軋型鋼熱軋型鋼有角鋼、工字鋼、槽鋼、T型鋼、Z型鋼等。我國建筑用熱軋型鋼主要采用碳素結構鋼Q235-A(含碳量為0.14-0.22%)，其強度適中，塑性及可焊性較好，成本低，適合建筑工程使用。在鋼結構設計規(guī)范中，推薦使用的低合金鋼主要有兩種：Q345(16Mn)及Q390(15MnV)，用于大跨度、承受動荷載的鋼結構中。冷彎薄壁型鋼通常是用2-6mm柏剛板冷彎或模壓而成，有角鋼、槽鋼等開口薄壁型鋼及方形、矩形等空心薄壁型鋼。主要用于輕型鋼結構。其標示方法與熱軋型鋼相同。鋼結構建筑重量輕、強度高、整體剛性好、變形能力強。</p><div

，相繼開發(fā)了高強鋼和耐火、耐候、耐海水、抗層狀撕裂、抗低溫用鋼，以及H 型鋼、高性能彩涂鋼板、冷彎型鋼等，為鋼結構產業(yè)的發(fā)展奠定了良好的應用基礎。鋼結構的上游主要是鋼鐵行業(yè)，鋼材產品價格波動直接影響本行業(yè)的采購成本。從整體上看，上業(yè)基本屬于競爭性行業(yè)，生產用于鋼結構的各類鋼板、鋼管、型鋼等鋼材，其中H 型鋼和中厚板是鋼結構建筑中較為常用的產品。產業(yè)洞察研究數據2011 年粗鋼產量達6.96 億噸，產量相對飽和，鋼結構生產所需的原材料能獲得穩(wěn)定的供應。連云港大型鋼結構廠房公司哪家好</p><p
