H型钢可以有效?；せ肪?，具体表现在三个方面：一是和混凝土相比，可采用干式施工，产生的噪音小，粉尘少；二是由于自重减轻，基础施工取土量少，对土地资源破坏小，此外大量减少混凝土用量，减少开山挖石量，有利于生态环境的?；?；三是建筑结构使用寿命到期后，结构拆除后，产生的固体垃圾量小，废钢资源回收价值高。

H-shaped steel can effectively protect the environment, which is embodied in three aspects: first, compared with concrete, it can adopt dry construction, resulting in less noise and less dust; Second, due to the reduction of dead weight, the amount of soil taken for foundation construction is small, and the damage to land resources is small. In addition, a large amount of concrete consumption is reduced, and the amount of rock excavation is reduced, which is conducive to the protection of the ecological environment; Third, after the service life of the building structure expires and the structure is dismantled, the amount of solid waste generated is small and the recovery value of scrap steel resources is high.

以热轧H型钢为主的钢结构工业化制作程度高，便于机械制造，集约化生产，精度高，安装方便，质量易于保证，可以建成真正的房屋制作工厂、桥梁制作工厂、工业厂房制作工厂等。

The steel structure mainly made of hot-rolled H-shaped steel has a high degree of industrialization, convenient for mechanical manufacturing, intensive production, high precision, convenient installation, and easy quality assurance. It can be built into a real house manufacturing factory, bridge manufacturing factory, industrial plant manufacturing factory, etc.

发展钢结构，创造和带动了数以百计的新兴产业的发展。工程施工速度快，占地面积小，且适合于全天候施工，受气候条件影响小。用热轧H型钢制作的钢结构的施工速度约为混凝土结构施工速度的2-3倍，资金周转率成倍提高，降低财务费用，从而节省投资。

The development of steel structure has created and driven the development of hundreds of emerging industries. The construction speed of the project is fast, the floor area is small, and it is suitable for all-weather construction, and the impact of climate conditions is small. The construction speed of steel structure made of hot-rolled H-shaped steel is about 2-3 times that of concrete structure. The capital turnover rate is doubled, reducing financial costs and saving investment.

济南型钢使用的过程中，堆放要合理，重要的是要码垛稳固，在保障安全的情况下，要同其它型号的型钢分开码垛，以免出现混淆。严禁在码垛的周围存放任何对材料有腐蚀性，或其它损害的物品。码垛时垛低是要进行垫高和稳固的，要保持垛低的稳固和凭证，在使用或者存放的过程中达到防潮和预防变形的效果。

In the process of using Jinan section steel, the stacking should be reasonable. The important thing is to stack it firmly. Under the condition of ensuring safety, it should be stacked separately from other types of section steel to avoid confusion. It is strictly prohibited to store anything corrosive to materials or other damage around the stacking. When stacking, the stacking height should be raised and stabilized, and the stability and evidence of the stacking height should be maintained to achieve the effect of moisture-proof and deformation prevention during use or storage.

在保存的场地或者仓库，要选择干净清洁，排水比较畅通的位置，存放场地的四周的杂草与其它杂物一定要清理干净，保持型钢的干净，同时要避免有害气体和各类粉尘直接接触700*300h型钢，从而延长材料的使用周期。

In the storage site or warehouse, choose a clean place with smooth drainage. Weeds and other sundries around the storage site must be cleaned to keep the section steel clean. At the same time, avoid harmful gases and various kinds of dust from directly contacting the 700 * 300h section steel, thus extending the service life of the material.

使用的过程中，切记不可同含有酸、碱、盐等性质的，具有腐蚀性的材料堆放在一起，施工现场的水泥也是具有腐蚀性的，亦不可共同存放。更多相关内容就来我们网站http://www.hhqhq.com咨询吧！

In the process of use, remember not to pile up with corrosive materials containing acid, alkali, salt and other properties. The cement at the construction site is also corrosive and cannot be stored together. Come to our website for more relevant content http://www.hhqhq.com Ask!
