Product Description

Steel profiles are steel products that have been rolled, drawn, or pressed.

Section steel can be divided into H-section steel, I-beam, channel steel, angle steel, flat steel and so on according to its cross-sectional shape. Among them, H-beam, I-beam, channel, and angle steel are hot-rolled, and flat steel is cold-rolled.

I-beam, channel, and angle steel are widely used in industrial buildings and metal structures, such as workshops, bridges, ships, agricultural machinery and vehicle manufacturing, transmission towers, and transportation machinery, often used in conjunction. Flat steel is used in construction sites as bridges, house frames, fences, power transmission ships, vehicles, etc.

 

The application characteristics of H-beam, angle steel, channel steel, and I-beam are introduced in detail below:

 

Application characteristics of H-beam

Hot-rolled H-beams have excellent mechanical properties and superior use properties by reasonably allocating the height to width ratio of cross-sectional dimensions according to different applications.

1, The design style is flexible and rich. In the case of the same beam height, the opening of a steel structure can be 50% larger than that of the concrete structure, thus making the building layout more flexible.

2, Light weight of the structure. Compared with the concrete structure, the weight of the structure is lighter, which reduces the design internal force of the structure and makes the foundation of the building structure less demanding, easy to construct and less costly.

3, The steel structure is mainly of hot-rolled H section steel, its structure is scientific and reasonable, good plasticity and flexibility, high structural stability, suitable for bearing vibration and impact load on large building structures, and strong resistance to natural disasters, especially for some multi-earthquake zone building structure. According to statistics, in the world's devastating earthquakes of more than 7 levels, the H-steel-based steel buildings suffer the least.

4, Increase the effective use area of the structure. Compared with concrete structure, steel structure column cross-sectional area is small, thus can increase the effective use area of the building, depending on the form of the building, can increase effective use area of 4-6%.

5, Compared with welded H-beam, it can significantly save labor and materials, reduce the consumption of raw materials, energy and labor, low residual stress, and good appearance and surface quality.

6, Easy to mechanical processing, structural connection and installation, but also easy to dismantle and reuse.

7, The use of H-shaped steel can effectively protect the environment, specifically in three aspects: First, compared with concrete, dry construction can be used, resulting in less noise, and less dust; second, due to the reduction of self-weight, foundation construction to take less soil, damage to land resources is small, in addition to a large reduction in the amount of concrete, reduce the amount of rock excavation, which is conducive to the protection of the ecological environment; third, after the expiration of the service life of the building structure, the structure demolition Thirdly, after the service life of the building structure expires, the structure will be dismantled and the amount of solid waste generated will be small, and the value of scrap steel resources will be high.

8, The steel structure mainly made of hot-rolled H-beam has a high degree of industrialization, which is convenient for machinery manufacturing, intensive production, high precision, convenient installation, and easy quality assurance, and can be built into a real housing production factory, bridge production factory, industrial plant production factory, etc. The development of steel structures has created and driven the development of hundreds of new industries.

9, The project construction is fast, covers a small area, is suitable for all-weather construction, and is little affected by the weather conditions. The construction speed of steel structures made of hot-rolled H-beam is about 2-3 times the construction speed of concrete structures, which increases the capital turnover rate exponentially and reduces the financial cost, thus saving investment. Take our country's "first tall building" Shanghai Pudong's "gold trade building" as an example, the main body of the structure up to nearly 400m in less than half a year to complete the structure of the roof, while the steel and mix structure require two years of work.

Angle steel application characteristics

Angle steel: commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other in an angle shape.

There are equal-sided angle steel and unequal-sided angle steel. The two sides of the equal-sided angle are equal in width, and its specifications are expressed in millimeters of the side width × side width × side thickness. Such as "∠30×30×3", that is, the side width of 30 mm, the side thickness of 3 mm equal-sided angle. The model number can also be used, the model number is the number of centimeters of the side width, such as ∠3#. The model does not indicate the size of the different side thicknesses in the same model, and thus the side width and side thickness of the angle on the contract and other documents will be filled out in full, to avoid using the model alone. The specification of the hot-rolled equilateral angle is 2#-20#.

Angle steel can be composed of various different force members according to the different needs of the structure, but also can be used as a connection between the members. It is widely used in various building structures and engineering structures, such as house beams, bridges, power transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves, etc.

Application characteristics of channel steel

Channel steel is a long strip of steel with a groove-shaped cross-section. Its specifications, such as 120 * 53 * 5, that is, the waist height of 120 mm, leg width of 53 mm, waist thickness of 5 mm channel steel, or 12 # channel steel. Waist height of the same channel, such as several different leg widths and waist thickness also needs to add a b c on the right side of the model to distinguish, such as 25a # 25b # 25c # and so on. The channel steel is divided into ordinary channel steel and light channel steel. The specifications of the hot-rolled common channel are 5-40#. The specifications of hot-rolled channel steel supplied by agreement between supply and demand are 6.5-30#.

Channels are mainly used in building structures, vehicle manufacturing and other industrial structures, and they are often used in conjunction with I-beams.

Application characteristics of I-beam

I-beam, also called steel beam, is a long strip of steel with a cross-section of I-beam. Its specification is expressed in mm of waist height (h) * leg width (b) * waist thickness (d), such as "I160*88*6", which means I-beam with waist height of 160 mm, leg width of 88 mm and waist thickness of 6 mm. The specification of the I-beam can also be expressed by the model number, which indicates the number of centimeters of waist height, such as I-16#. Waist height of the same I-beam, such as several different leg widths and waist thicknesses, need to add a b c to the right of the model to distinguish, such as 32a # 32b # 32c #. I-beam is divided into ordinary I-beam and light I-beam, and the specification of hot-rolled ordinary I-beam is 10-63#. The specifications of hot rolled ordinary I-beam supplied by agreement between supply and demand are 12-55#.

I-beams are widely used in various building structures, bridges, vehicles, brackets, machinery, etc.
