The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as s235jr steel plate 40mm thick, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.

s235jr steel plate 40mm thick 5mm to 10mm stock size5.5*2900*7400, 8*2400*6000, 9*2500*9500, 5*3000*5200, 6*2350*6300, 10*2000*6500, 8*2400*8000, 7*3000*6600, 6*2350*7400, 10*2150*5500, 8*2300*9000, 8*2400*8000, 6*2350*7200, 10*2550*10500, 8*2490*7200, 8*1800*10000, 10*2360*7700, 10*2490*8400, 9*2500*7400, 8*1800*8000, 10*2450*8000, 10*2100*11000, 10*2450*8000, 10*1650*9020.

45# seamless steel pipe (No.45 seamless steel pipe) is Chinese high-quality carbon structural steel, which is called S45C in Japanese standard, AISI 1045 in American standard, and C45 in German standard. The difference between 45# seamless steel pipe and 20# seamless steel pipe is that its hardness is obviously higher than that of 20# seamless steel pipe. The tempering brittleness of s235jr steel plate 40mm thick, 45# seamless steel pipe is high. After quenching and tempering, 45# seamless steel pipe has good mechanical properties. If the wear resistance is considered, heat treatment is required.

Construction preparation for steel plate cutting: the s235jr steel plate 40mm thick steel plate used for cutting shall be inspected and accepted by the quality department, and its indicators shall meet the corresponding provisions of the specification.The grade, thickness and surface quality of the steel plate should be checked before discharging the steel plate. If the depth of the corrosion point on the surface of the steel plate exceeds the negative deviation of the national standard, it is not allowed to be used for the product.
