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:What does "L125*8" stand for in steel structures?
Equal angle steel, width 125, wall thickness 8
Q:Can galvanized square tubes and angle iron be welded together?
If you do not clean out the galvanized layer or is not completely clear, it will cause the zinc layer and instantaneous combustion will produce a large number of yellow white floc toxic gases, the most serious is will have a direct effect on the magnetic blow angle due to interruption of welding.
Q:Which is cheaper, angle iron and steel pipe?
Angle iron and steel pipe, angle iron is cheap.
Q:What does angle 5 mean?
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. Also available models that model is the number of centimeters wide, such as angle 3#. The model does not mean the size of the different edges and sizes of the same model. Therefore, the width, the edge and the thickness of the angle iron should be filled out in the contract and other documents, so as not to be indicated by the model alone. Standard Specification for hot-rolled equal angle iron is 2#-20#.
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,
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:Where does channel steel use more. Where does angle iron use more?
Hot rolled stainless steel light channel steel (YB164-63) hot rolled light channel steel is a kind of steel with wide legs and thin wall, which has better economic effect than ordinary hot rolled channel steel. Its specifications range from 5-40#. In 1966, standard specifications ranged from 10-40#. Main applications: building and steel structure etc..
Q:What is angle flower? Is it the same as angle iron?
Welded steel pipe, welded pipe, welded steel pipe, is the same meaning, also called welded steel pipe, seamless steel tube is compared with the. Seamed tube is made of steel plates or strips welded together. Because of the different manufacturing process, it can be divided into longitudinal welded pipe and spiral welded pipe.
Q:What is the difference between the main keel and the angle steel or the channel steel?
Channel steel is a kind of carbon structural steel used for construction and machinery. It is a complex section steel. Its cross section has a groove shape. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing, etc.. In use, it requires better welding, riveting performance and comprehensive mechanical properties. The raw material steel billet for channel steel is carbon or low alloy steel billets with a carbon content of not more than 0.25%. The finished channel steel is delivered by hot forming, normalizing or hot rolling. The specifications are expressed in millimeters of height (H) * leg width (b) * waist thickness (d), such as 100*48*5.3, which means waist height is 100 mm, leg width is 48 mm, waist thickness is 5.3 mm channel, or 10# channel steel. The same height of the channel, if there are several different leg width and waist thickness, also need to add a, B, C on the right side of the model to distinguish, such as 25#a, 25#b, 25#c and so on.
Q:What material is angle iron?
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 frame and warehouse.
