What is the difference between steel structure HN and HW?

Difference:

(1) H-beam steel is welded, HM, HN, HW is hot-rolled, HM is called middle flange H-beam, is the ratio of H-beam steel height to flange width is 1.33-1.75, mainly used as steel frame column in steel structure, and forever used as frame beam in the frame structure bearing load, such as equipment platform. , HW is called wide flange H-beam, is the height of H-beam steel and flange width is basically equal, mainly used in steel core column in steel frame structure, also known as rigid steel column, in steel structure is mainly used for columns. , WH270*250*18*23 is welded H-beam. W is the first letter of the weld. , 1 construction preparation, (1) technical preparation: formulate the installation technical plan, single-layer steel structure engineering should adopt the piece-based installation method, and the roof should adopt the comprehensive installation method. Multi-layer steel structure engineering generally adopts the comprehensive installation method

(2) Construction tools and material preparation: including lifting machinery, various auxiliary construction tools, steel components, various welding materials and fasteners, etc.

(3) Column base inspection: column base leveling and elevation control, review the axis and spring the installation alignment line, check the position, size and quality of the anchor bolt axis.

(4) Component cleaning: clean up the steel column and other advanced lifting components, number and bounce the installation line.
