The Hebei Hua Tuo Jia Ye Steel Trading Co., Ltd. a sale: Manager Ma 0311 67,790,216 1,393,042,522,380,816,223 two sales: Geng Jingli 0311 80,984,616 1,301,436,639,980,984,606 Fax 0311 -67,790,217 Website: http:www.hbhtgt.net I-beam ordinary beam, light beam, H-shaped steel is divided into three kinds. Ordinary beam, light beam flange is a variable cross-section depend on the thickness of the web portion of the external thin; H-beam: HW HM HN HEA HEB HEM-beam flange section ordinary beam, light word Steel has formed a national standard, ordinary 10 # I-beam is equivalent to international I100 (such as 10 # channel equivalent to channel U100) (because of the different countries to implement the standard, there are subtle differences, resulting in their specifications) H I-beam, also known as flange steel HW HM HN derived from European standards, HEB is the German standard I-beam. Which I, HW, HN-beam has been widely used in China and production. HEA HEB HEM will see many German design, difficult to buy in the domestic market. In the domestic steel construction, the less you can use the other specifications of the steel plate welded splicing. The large amount of usually consider the use of mechanical properties with considerable HW, HN steel instead. HW-beam is mainly used for steel core columns in the column of reinforced concrete frame structure, also known as reinforced with steel columns; mainly used in the steel column the HM-beam height and flange width ratio of roughly 1.33 ~ ~ 1.75, in the steel : steel frame columns used as to do frame beam subjected to dynamic loads using the frame structure; example: the device platforms HN steel height and flange width ratio greater than or equal to 2; mainly for beam ordinary beam use equivalent to HN steel ; Scope ordinary beam, light beam, due to the cross-sectional dimensions are relatively high, narrow, so the moment of inertia of the cross-section of two main sleeve large difference, therefore, generally only used in its web plane flexural member or its composition grid construction force component. Axial compression members or perpendicular to the web plane bending member should not be used, which has very much restricted in its range of applications. The use of the I-beam shall be selected in accordance with the requirements of design drawings. H-beam flange welding process are of equal thickness, rolled sections, also three plate welding composite section. The ordinary beam are rolling cross-section, due to the production process, the flange side 1:10 slope. H-beam rolling is different from the ordinary beam only a set of horizontal roll, wide flange and no inclination (or slope is very small), require the creation of a set of vertical roll and roll, rolling process and equipment than the ordinary mill complex. Domestic produce rolled H-beam height of 800mm, more than can only be welded composite section. The narrow flange h beam suitable for beam or bending member, wide-flange h beam h steel pile is applicable to axial compression members or members with flexure and compression. Ordinary beam, light beam HW, HN steel, such as the weight of the premise, w, ix, iy not as good as the H-beam. Perennial with a variety of materials of high quality pipes, profiles, seamless, non- pipe joints, structural tubes, transmission fluid, low and medium pressure boiler pipe, high pressure pipe, high pressure boiler tube, fluid pipe, oil cracking pipe, fertilizer, all kinds of alloy tube. Aggregators clad, Cheng Gang, Steel, Anshan Iron and Steel, Baoshan Iron and Steel, Hengyang Steel, Tianjin Steel and other brand-name manufacturers seamless tube. Profiles: beams, channels, angles, H-shaped steel. Through years of efforts, the company has become a large-scale stainless steel pipe, stainless steel, alloy steel pipe, carbon steel sales base. Met with the country's major power plants, boiler plants, petroleum, chemical, mechanical, etc. to expand the market, and has established an extensive sales network, has a certain reputation. The company adhere to contractual commitments, the quality of products and services and is willing to work with new and old customers sincere cooperation, create a better future.
