What are the meanings of I-beam BH300 x 200 x 6 x 8 in steel structures?
BH is welded to H type steel, not hot-rolled steel H from steel mill. Generally processed by the factory with three pieces of steel welded. BH300*200*6*8, i.e., high 300mm* wide 200mm* web 6mm* flange 8mm.

Steel structure is mainly made of steel material, and it is one of the main types of building structure. The structure is mainly composed of steel beams and steel plates, such as steel beams, steel columns, steel trusses and so on. Each component or component is usually connected with welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields.
I-beam is also called steel girder (English name Universal Beam). It is a strip of steel with an I-shaped section. I-beam is made of ordinary I-beam and light i-beam. It is a section steel whose shape is trough.
The ratio of the area of a longitudinal force (tension or pressure) to the effective area of a member (the axial compression member is a full cross section). The reinforcement ratio and the reinforcement ratio of the compression bar are calculated respectively. Formula: P =A (s) /bh (0). Here is the angle brackets below.Type: A (s) is the cross-sectional area of the longitudinal reinforcement in tension or compression zone; B is the width of the rectangular section; H (0) is the effective height of the cross section. The reinforcement ratio is a parameter that reflects the number of reinforcement.The minimum reinforcement rate is that, when the beam reinforcement ratio is very small, the beam tension zone after cracking, the steel stress tends to yield strength, the reinforcement rate is called the minimum reinforcement ratio (min). The minimum reinforcement ratio is determined according to the principle that the ultimate flexural capacity M (U) of the member section is equal to the bending moment M (CR) equal to the tensile moment of the concrete member under tension.
