In the attachment, I send you a sheet of steel. You can refer to it. According to the theory, 2 t hoist with 20 a 6 m span beams, but now consider the national conditions, should rise a again, and may appear overload and safety point of view, advice for a 25. In addition, I will give you a piece of steel size/dimension/weight picture.
H beams are also called wide flange beams, HW HM HN from European standard, HEB is Germany standard beams, including HW, HN beams has been widely used in our country and production. HEA HEB HEM is seen in many German design drawings and is difficult to buy in the domestic market. In domestic steel structure engineering, if the quantity is low, the steel plate of the specification can be welded and spliced. In large quantities, it is usually considered that the mechanical properties of HW and HN are substituted.
B: steel, with a channel of steel on it. It is also known as the steel girder (the English name Universal Beam), which is a long piece of steel in the shape of the section. It is made of ordinary steel and light industrial steel. The shape of the section is the shape of the shape.
