The main purpose of the corner slot is mainly used for building structures, vehicle manufacturing and other industrial structures. Channel steel is often used in conjunction with I-beams.
The major origins of industrial angle tanks in China are mainly produced by a few steel mills such as Baotou Steel, Laiwu Steel, Wuhan Steel and Maanshan Iron and Steel.
I-beams I-beams, also known as steel beams, are long strips of steel with an I-section. Its specifications are expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d). For example, "worker 160*88*6" means that the waist height is 160 mm, the leg width is 88 mm, and the waist thickness is 6 mm I-beam. I-beam specifications can also be used to represent the model, the model shows the height of the waist centimeters, such as workers 16 #. If the waist height of the same I-beam, if there are several different leg width and waist thickness, need to add abc on the right side of the model to distinguish, such as 32a # 32b # 32c # and so on. I-beams are divided into ordinary I-beams and light I-beams. The specifications of hot-rolled I-beams are 10-63#. The standard hot-rolled I-beams supplied by the supplier and buyer are 12-55#. I-beam is widely used in various building structures, bridges, vehicles, supports, machinery and so on.
The difference between the I-beam HW HM HN H-beam is that the flange of the I-beam is changed to the thickness of the web and the outside is thin; the flange of the H-beam is used
HW HM HN H is the general name of H-shaped steel, H-shaped steel is welded and HW HM HN is hot rolling
HW is basically equal to the height of H beam and the width of the flange; it is mainly used for the steel core column and the steel column in the reinforced concrete frame structure column; it is mainly used for the column in the steel structure.
HM is the ratio of H-beam height and flange width roughly 1.33~~1.75 Mainly in steel structure: used as steel frame column Used as frame beam in frame structure subject to dynamic load; for example: equipment platform
HN is the proportion of H-beam height and flange width greater than or equal to 2; mainly used for beams;
The use of I-beam is equivalent to HN steel;
1. For I-beams, whether they are common or lightweight, because the cross-sectional dimensions are relatively high and narrow, the moments of inertia of the two main sleeves in the cross section are quite different. Therefore, they can only be used directly on their webs. The in-plane bent member or the lattice-formed force member. It is not appropriate to use axial compression members or members that are bent perpendicular to the plane of the web, which limits its application.
2. H-beams are highly efficient and economical profiles (others include cold-formed thin-walled steels, profiled steel plates, etc.). Due to their reasonable cross-sectional shape, they can enable steels to perform more efficiently and improve their cutting capabilities. Unlike the general I shape, the flanges of the h-beam are widened and the inner and outer surfaces are generally parallel, which facilitates connection with high strength bolts and other components. Its size constitutes a reasonable series, complete model, easy to design and use.
3. The flanges of h-section steel are of equal thickness, have a rolled cross section, and also have a combined section consisting of 3 plates welded. I-beams are rolled sections, due to poor production processes, the edge of the flange has a 1:10 slope. The rolling of H-shaped steel is different from ordinary I-beam using only a set of horizontal rollers. Because its flange is wide and has no inclination (or a small gradient), a set of vertical rollers must be added and rolled at the same time. The rolling process and equipment are more complex than ordinary rolling mills. The maximum height of rolled steel h-shaped steel that can be produced in China is 800mm, which can only exceed the welding combination section.
China's hot-rolled H-beam national standard (GB/T11263-1998) divides the h-beam into three categories: narrow flange, wide flange and steel pile. The codes are hz, hk and hu. The narrow-flange h-beam is suitable for beam or compression-bending members, while the wide-flange h-beam and h-beam are suitable for axial compression members or press-bend members. Compared with H-shaped steel, H-shaped steel is not as good as h-shaped steel under the premise of equal weight.
Angle Steel Overview Angle steel, commonly known as angle iron, is a long strip of steel that is perpendicular to each other on both sides. There are equilateral and unequal angles. Equilateral angles are equal in width on both sides. Its specifications are expressed in millimeters of side width, side width and side thickness. For example, “∠30×30×3†means an equal angle steel with an edge width of 30 mm and a thickness of 3 mm. Can also be used to model, model is the width of the centimeters, such as ∠3 #. The model does not indicate the size of the different sides in the same model. Therefore, the angle and thickness of the angle steel are filled in on the contract and other documents, avoiding separate models. The specification of hot rolled equal angle steel is 2#-20#.
Angle steel can be composed of different kinds of force members according to the different requirements of the structure, and can also be used as the connection between the components. Widely used in a variety of building structures and engineering structures, such as house beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnaces, reaction towers, container racks, and warehouse shelves.
Carbon steel for construction of angle steel is a simple section of steel, mainly used for metal components and factory buildings. In use, it requires good weldability, plastic deformation properties and certain mechanical strength. The raw material billets for the production of angle steel are low carbon steel billets, and the finished angle steel is delivered in hot rolled, normalized or hot rolled state.
Import and Export Situation China's import and export angles each have a certain volume, mainly imported from Japan and Western Europe. Exports to the region are mainly Hong Kong and Macao, Southeast Asia, Latin America and Arab countries. Export production companies are mainly steel mills (rolling mills) in Liaoning, Hebei, Beijing, Shanghai, Tianjin and other provinces and cities.
Most of the imported angle steels are large-sized, small angle steels and special-shaped angle steels. The export varieties are mostly medium-sized angle steels such as No.6 and No.7.
The major origins of industrial angle tanks in China are mainly produced by a few steel mills such as Baotou Steel, Laiwu Steel, Wuhan Steel and Maanshan Iron and Steel.

Custom Aluminum Composite Panel
Acm Panels are lightweight but rigid and durable aluminum composite material (ACM)-two strong sheets of aluminum bonded to a solid polyethylene core. The panel is prepared with canvas mounted on one-side and a mill (polished aluminum) finish on the other side. The panels are custom fabricated in inch increments from 6 to 24 inches. This weather-resistant panel is ideal for a wide range of paint mediums.
Compared to wood panels ACM panels offer a superior support for painting and mounting because ACM panels are virtually unaffected by environmental changes, such as relative humidity (RH) and temperature. This is a professional panel for oil and acrylic painting.
