What is the formula for calculating the weight of I-beam？

H-shape steel perfect advantages:

H-shaped steel can be processed into T-shaped steel, and honeycomb beams can be combined to form various cross-section forms, which greatly meet the needs of engineering design and production

Wide flange, large lateral stiffness, strong bending resistance

The two surfaces of the flange are parallel to each other, which makes the connection, processing and installation easy

Compared with welded I-beam steel, low cost, high precision, small residual stress, no need for expensive welding materials and weld detection, saving steel structure production cost of about 30%

Under the same section load. The weight of hot-rolled H steel structure is 15%-20% less than that of traditional Tong structure.

Compared with the concrete structure, the hot-rolled H steel structure can increase the use area by 6%, and the structure's self-weight can be reduced by 20% to 30%, reducing the design internal force of the structure.

4. H-shaped steel material:

Q235a, Q235b, Q235c, Q235d, Q345a, Q345b, Q345c, Q345d

Weight calculation formula:

W = 0.00785 x (2 h + b * t2 * t1)

h= High

b= wide

t1= web thickness

t2= wing thickness

Cold rolling of galvanized H-shaped steel must be higher methods and technical standards, galvanized H-shaped steel manufacturers feel that when manufacturing large and medium-sized H-channel steel, it is necessary to fully prepare from the following levels, and effectively manipulate various hazardous elements in the whole process of the production process.

What is the formula for calculating the weight of I-beam

Hot-dip galvanizing processing foreign end discharge unit adopts the process of first blowing outside, then blowing inside. Compared with the process of drawing galvanized steel pipe from the inner roller, this process can obtain good galvanized quality and reduce zinc consumption and energy consumption.

This is because the galvanized steel pipe is attracted and carried away under the magnetic roller, and the surface of the pure zinc layer after blowing zinc will not be squeezed out of the zinc gray spots by the roller surface. Second, the external blowing nozzle is installed above the end of the galvanized pot, and the blown zinc drops can be immediately returned to the galvanized pot.

"Wet" hot dip galvanizing is to place the flux (mainly sodium chloride + zinc chloride) in a special bottomless flux box on the surface of the zinc liquid, and the steel pipe must be entered by the flux box before dipping the zinc liquid, and then enter the zinc liquid below after dipping the flux, and be drawn out after galvanizing. The process system is as follows:

Flux temperature: 300-350℃;

Zinc liquid temperature: 450-470℃;

Higher allowable iron content in zinc liquid: 0.05%;

Zinc dipping time: 20-60 seconds.
