1. Structure of Cold Rolled Drawn Slit Cutting Steel Flat Bar Description:
Cold rolled drawn slit cutting steel flat bar is a beam with an I-shaped cross-section. The horizontal elements of the "I" are known as flanges, while the vertical element is termed the "web". Cold rolled drawn slit cutting steel flat bar is usually made of structural steel and is used in construction and civil engineering. The cold rolled drawn slit cutting steel flat bar resists shear forces, while the flanges resist most of the bending moment experienced by the beam. Cold rolled drawn slit cutting steel flat bar theory shows that the I-shaped section is a very efficient form for carrying both bending and shears loads in the plane of the web.

5. FAQ
We have organized several common questions for our clients，may help you sincerely:
①Is this product same as W beam？
In the United States, the most commonly mentioned I-beam is the wide-flange (W) shape. These beams have flanges in which the planes are nearly parallel. Other I-beams include American Standard (designated S) shapes, in which flange surfaces are not parallel, and H-piles (designated HP), which are typically used as pile foundations. Wide-flange shapes are available in grade ASTM A992,[4] which has generally replaced the older ASTM grades A572 and A36.
②How to inspect the quality？
We have a professional inspection group which belongs to our company. We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.
③Is there any advantage about this kind of product?
Steel I beam bar IPE has a reduced capacity in the transverse direction, and is also inefficient in carrying torsion, for which hollow structural sections are often preferred.
