彎曲度：工字鋼高度小于或等于400MM時，每米彎曲度不得大于1.5MM，總彎曲度不得大于總長度的0.15%。高度大于400MM時，每米彎曲度不得大于1.0MM，總彎曲度不得大于總長度的0.1%。
Bending degree: when the height of the I-steel is less than or equal to 400MM, the bending degree of each meter must not be more than 1.5MM, and the total bending degree should not be more than 0.15% of the total length. When the height is greater than 400MM, the bending degree of each meter must not be more than 1.0MM, and the total bending degree should not be more than 0.1% of the total length.
工字鋼的邊長小，高度大，只能承受單方向的力。 H型鋼槽深，厚度大，可以承受兩個方向的力。
工字鋼只能用于橫梁，而H型鋼才能用于結構的承重柱。
The length of the I-steel is small and high. It can only bear the force of the single direction. The H steel groove is deep and thick, and can bear the force of two directi.
I-steel can only be used for crossbeams, and H steel can be used for structure bearing columns.
隨著科學技術和工業的發展，對材料提出了更高的要求，如更高的強度，抗高溫、高壓、低溫，耐腐蝕、磨損以及其它特殊物理、化學性能的要求，碳鋼已不能完全滿足要求。
With the development of science and technology and industry, the material has put forward higher requirements, such as higher strength, high temperature, high pressure, low temperature, corrosion resistance, wear and other special physical and chemical properties, carbon steel can not fully meet the requirements.
