Application characteristics of I-beam

Application characteristics of I-beam

Due to the relatively high and narrow cross-sectional dimensions of ordinary I-beams and light-weight I-beams, the moment of inertia of the two main sleeves of the cross-section is quite different, which greatly limits their application range. The use of I-beams should be selected according to the requirements of the design drawings.

Advantages of I-beams

Advantages of I-beams

I-shaped beams are hollow web members. For high-strength materials, hollow web members are better than solid web members in terms of weight, material, and labor saving. This cross-sectional design mainly uses the flange farthest from the centroid to resist bending moments (because the farther the flange is, the greater the moment of inertia), and mainly uses the web to resist shear. As for the inconvenience in making it, it can be solved by factory or molding. Saving materials, labor, and time is efficiency.

Advantages and Disadvantages of Stainless Steel Plate

Advantages and Disadvantages of Stainless Steel Plate

To sum up, stainless steel plates have many advantages, such as corrosion resistance, high strength, aesthetics, hygiene and recyclability. However, there are some disadvantages, such as high cost, easy scratching, heavy weight and poor thermal conductivity. When choosing to use stainless steel plates, you need to comprehensively consider its advantages and disadvantages and make a reasonable choice based on specific application requirements.

How to determine the specifications of channel steel

How to determine the specifications of channel steel

The delivery length of channel steel can be divided into two types: fixed length and double length, and the tolerance value shall be specified in the corresponding standards. The length selection range of domestic channel steel is divided into three types based on different specifications: 5-12m, 5-19m, and 6-19m. The length selection range of imported channel steel is generally 6-15m.

Preparation method of carbon steel pipe

Preparation method of carbon steel pipe

The raw material of carbon steel pipe is round tube blank, which needs to be cut and processed by a cutting machine to form a billet with a length of about 1 meter, and then sent to the furnace for heating through a conveyor belt. The billet is fed into the furnace for heating, with a temperature of approximately 1200 degrees Celsius.
