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's the chemical reaction between stainless steel and galvanized angle iron?
The essential condition for stainless steel to be corrosion resistant is that the mass fraction of chromium must be greater than 10~12%. When the temperature increases, the diffusion velocity of carbon in the grain of stainless steel is higher than that of chromium. Because the solubility of carbon in austenite at room temperature is very small, about 0.02% ~ 0.03%, and the carbon content in austenite stainless steel are generally more than this value, the excess carbon will continue to austenite grain boundary diffusion, and chromium compounds, compounds of chromium carbide in the crystals, such as 23C6 (CrFe) etc.. The data show that chromium diffusion along the grain boundary activation capacity of 162 ~ 252KJ/mol, and Cr intracrystal diffusion activation energy is about 540KJ/mol, namely: chromium by intracrystal diffusion faster than chromium diffusion along the grain boundary velocity is small, the chromium was too late to grain boundary diffusion, so the main chromium chromium carbide formed in intergranular required not from the austenite grain interiors, but from the vicinity of the grain boundaries, the chromium content makes near the grain boundary is reduced, when the mass fraction of the grain boundary chromium low to less than 12%, the formation of the so-called "chromium depleted zone", in corrosion, will lose the chromium depleted zone corrosion resistance, and intergranular corrosion.
Q:What material is angle iron?
Angle called angle, the steel strip is perpendicular to each other on both sides into the corner. There are equal angles and unequal angles. The two sides of an equal angle steel are equal in width.
Q:Which is cheaper, angle iron and steel pipe?
Steel tube (Steel pipe) production technology development began in the bicycle manufacturing industry, the rise of the early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry of petroleum and natural gas drilling and transportation, will effectively promote the the yield and quality of varieties, the development of steel tube industry.
Q:What is the keel of the aluminum single board suspended or the welded frame of angle steel?
Aluminum curtain wall veneer made of high strength Aluminum Alloy plate, its structure is mainly composed of a panel, stiffener and bracket component. Code can be directly by the panel bending, stamping molding, but also in the panel on the hems of riveting corner molding. The reinforcing ribs and the plate after the welding nail connection, make it become a strong overall, greatly enhance the rigidity and strength of single aluminum plate curtain wall, to ensure the long-term use of smoothness and anti-seismic capability. A lot of single plate shaped type, is also the largest, others with no keel, the ceiling of the room is generally used with plate, steel keel, length of 3 meters
Q:Bearing capacity of angle steel and channel steel
Channel steel is a strip of steel with a cross section. Section steel with groove shape.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.Channel steel is divided into ordinary channel steel and light channel steel. Standard Specification for hot-rolled plain channel steel is 5-40#. Specifications for hot rolled flexible channel steel supplied by supply and demand agreement are 6.5-30#. Channel steel is mainly used for building structures, vehicle manufacturing, other industrial structures and fixed plates, cabinets, etc., and channel steel is often used in conjunction with i-beam.
Q:Galvanized steel angles under what conditions?
Iron tower and other exposed steel structures are often used
Q:What does "angle length" and "limb width" mean?
The width of a limb refers to the width of the point to the edge of the angle, and the length of the limb corresponds to the length of the edge;Angle called angle, the steel strip is perpendicular to each other on both sides into the corner. There are equal angles and unequal angles. 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.
Q:What is 4# angle iron? What are the classifications of angle iron? What are the specifications? Thank you
Angle called angle, the steel strip is perpendicular to each other on both sides into the corner. There are equal angles and unequal angles. 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. 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#. 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 frame and warehouse.
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:What is the difference between the main keel and the angle steel or the channel steel?
The boat in the boat, the boat is keel or load-bearing structure is the most important. It's at the bottom of the ship. On the keel, there is reinforcement across the ship's ribs. The bow and stern keel off the bow post. The keel is usually the first one to be part of the hull construction. The keel laying is the most important event in the shipbuilding process.
