Usage & Applications of Angle Steel

According to the needs of different structures, Angle can compose to different force support component, and also can be the connections between components. It is widely used in various building structures and engineering structures such as roof beams, bridges, transmission towers, hoisting machinery and transport machinery, ships, industrial furnaces, reaction tower, container frame and warehouse etc.

Packaging & Delivery of Angle Steel

1. Packing: it is nude packed in bundles by steel wire rod

2. Bundle weight: not more than 3.5MT for bulk vessel; less than 3 MT for container load

3. Marks:

Color marking: There will be color marking on both end of the bundle for the cargo delivered by bulk vessel. That makes it easily to distinguish at the destination port.

Tag mark: there will be tag mark tied up on the bundles. The information usually including supplier logo and name, product name, made in China, shipping marks and other information request by the customer.

If loading by container the marking is not needed, but we will prepare it as customer request.

Q:Which is cheaper, angle iron and steel pipe?
Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
Q:304 what does angle iron stand for?
304 is a versatile stainless steel which is widely used in the manufacture of equipment and parts requiring good overall performance (corrosion resistance and formability). 304 stainless steel is a brand of stainless steel produced according to the ASTM standard in the United states. 304 chromium 19%, containing nickel 9%.
Q:Unequal angle steel
Unequal angle steel is a cross section, such as the letter "L", with each side of each other vertically angled and of unequal width. Its specifications are expressed in long, wide, short, wide and * thick edges, such as "L30*20*3", i.e., unequal angles with long sides, wide 30mm, short width, 20mm, and 3mm of edge thickness. Can also use the model (number) said that the model represented by a fraction, molecular side length cm wide, the denominator for the short side number of centimeters wide, such as "L3/2#", said the 3 cm long side, short side said 2 centimeters. The specifications for unequal angles are 2.5/1.6#-20/12.5#.
Q:What is the difference between galvanized steel bar and ordinary angle iron?
Durable: galvanized steel with surface gloss, zinc layer uniform, no plating leakage, without drip, strong adhesion characteristics, strong corrosion resistance, in a suburban environment, galvanized thickness standard can be maintained for more than 50 years without repair; in urban areas or coastal areas, the standard hot galvanized layer it can be maintained for 20 years without repair;
Q:What is the meaning of the number of angle steel
The two sides of an equal angle steel are equal in width. The specifications are expressed in millimeters of edge width * edge width * edge thickness. Such as "/ 30 x 30 x 3", that is 30 mm width equal angle, edge thickness of 3 mm. The model can also be used, also the title number, number is the number of centimeters wide, such as the No. 3 angle angle 3#.
Q:What's the size of the 50 angle iron?
Specification for 50 equal anglesTwo sides at right angles, 90 degrees. The length of the side is 50mm, and the thickness of the edge is 3mm, 4mm, 5mm and 6mm. The corresponding weight of each meter is 2.332 kg, 3.059 kg, 3.770 kg, 4.465 kg, respectively, four kg.
Q:Where does channel steel use more. Where does angle iron use more?
The stainless steel angle can be made up of different stress components according to the different structure, and it can also be used as the connecting piece between the components. Widely used in a variety of architectural and engineering structures, such as beams, bridge [/url], transmission tower, lifting transport machinery, ships, industrial furnace, reaction tower, container rack and warehouse shelves.Stainless steel angle steel is constructed with carbon structural steel. It is a simple section steel. It is mainly used in the frame of metal component and workshop. In use, better weldability, plastic deformation and mechanical strength are required. The raw material for producing stainless steel angle steel is low carbon square billet, the finished product is made of stainless steel and the angle iron is delivered by hot rolling forming, normalizing or hot rolling.
Q:How can the angle iron tripod be welded or not?
The angle iron can be made up of different force components according to the different structure, and can also be used as the connecting piece between the components. Widely used in a variety of architectural and engineering structures, such as beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container rack and warehouse shelves.
Q:How to determine the neutral axis of the angle bar?
The neutral axis is a line which is the intersection of the neutral plane and the neutral axis corresponding to the strong axis of the cross section. The neutral axis is equal to the bisector of the sectional area parallel to the curved main axis, and the area on both sides of the neutral axis is equal, and the biaxial symmetry section is the centroid axis.
Q:Can iron angle steel be welded with stainless steel angle steel?
If the angle, in a cross-sectional angle welding of carbon steel plate, stainless steel angle welding a stainless steel cross sectional iron. Two cross cutting iron plate punching, 8.8 high strength screw fastening piece.Carbon steel and stainless steel welding, belong to dissimilar metal welding. Higher requirements for welding technology. Screw connections are the most economical,
