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.
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.
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.
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.
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.
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.jnhxtcg.com Ask!
