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:Can steel angles be used for pipe supports or hangers?: Yes, steel angles can be used for pipe supports or hangers. Steel angles provide structural support and stability for pipes, making them suitable for various applications in the construction and industrial sectors. The L-shape design of steel angles allows for easy attachment to walls, ceilings, or other structural members, providing a sturdy base for suspending or supporting pipes. Additionally, the strength and durability of steel angles make them capable of withstanding the weight and pressure exerted by the pipes, ensuring long-term stability and reliability. Overall, steel angles are a commonly used and effective choice for pipe supports and hangers.

Q:How do you calculate the critical buckling load for a steel angle?: To calculate the critical buckling load for a steel angle, you would use the Euler buckling formula, which states that the critical buckling load is equal to the Euler buckling stress multiplied by the cross-sectional area of the angle. The Euler buckling stress can be determined by using the formula σ = (π^2 * E) / (l / r)^2, where σ is the Euler buckling stress, E is the elastic modulus of the steel, l is the length of the angle, and r is the radius of gyration of the angle's cross-section.

Q:What are the different types of connections used for steel angles in steel frames?: There are several types of connections used for steel angles in steel frames, including welded connections, bolted connections, and riveted connections. Welded connections involve fusing the angles together using heat, creating a strong and permanent bond. Bolted connections involve using bolts and nuts to secure the angles together, allowing for easy disassembly if necessary. Riveted connections involve using rivets, which are metal pins, to hold the angles together by forming a permanent, tight fit. The choice of connection type depends on the specific requirements of the steel frame and the desired level of strength and durability.

Q:Can steel angles be used for manufacturing window frames?: Indeed, the utilization of steel angles is feasible for the production of window frames. Given their robustness, longevity, and versatility, steel angles are extensively employed in both construction and manufacturing. They furnish a robust structure for windows, capable of enduring the weight and force exerted by the window glass. The assembly of steel angles through welding, bolting, or screwing allows for the creation of a robust and steady window frame. Furthermore, steel angles can be tailored to meet precise design specifications, rendering them suitable for a wide array of window sizes and shapes. All in all, owing to their dependability, strength, and adaptability, steel angles are a favored option for the manufacturing of window frames.

Q:Are steel angles available in different grades of steel?: Different grades of steel are available for steel angles, which are widely used in the construction and manufacturing industries for various purposes including structural support, framing, and bracing. The grade of steel used in steel angles is determined based on its chemical composition, mechanical properties, and intended use. A36, A572, and A588 are some common grades of steel used for steel angles, each with specific characteristics suited for different applications. For instance, A36 steel angles are commonly utilized for general structural purposes, whereas A572 steel angles possess higher strength and are often utilized in heavy-duty construction projects. The selection of the grade depends on factors like load-bearing capacity, corrosion resistance, and cost considerations.

Q:What is the maximum allowable torsional stress for a steel angle?: The maximum allowable torsional stress for a steel angle depends on various factors such as the type of steel, its dimensions, and the specific application. Therefore, it is not possible to provide a specific value without more information.

Q:What is the typical thickness of the flanges of a steel angle?: The thickness of the flanges of a steel angle can differ depending on the particular application and industry norms. Typically, flanges of a steel angle are often available in thicknesses ranging from 1/8 inch to 3/4 inch. It is significant to consider that thicker flanges offer greater strength and stability, but also contribute to the weight and cost of the steel angle. To determine the suitable flange thickness, one should consider the specific project requirements and any relevant engineering or design standards.

Q:Can steel angles be used for manufacturing equipment frames?: Indeed, the utilization of steel angles in the fabrication of equipment frames is possible. Their strength, durability, and versatility render steel angles frequently employed in construction and manufacturing fields. By providing structural support and stability, they prove to be an optimal choice for the design and construction of equipment frames. The ease with which steel angles can be welded or bolted together enables the creation of rigid and robust frame structures. Moreover, their ability to be cut into specific lengths and shapes allows for precise assembly and customization. In conclusion, the reliability and cost-effectiveness of steel angles make them a favored selection for the manufacturing of equipment frames.

Q:Can steel angles be used for electrical conduits?: Steel angles cannot serve as electrical conduits. Electrical conduits are commonly made from non-metallic materials like PVC or metal materials such as galvanized steel or aluminum. Steel angles, on the other hand, are utilized for structural support and reinforcement in construction endeavors, but they are not intended or appropriate for use as electrical conduits. Electrical conduits have specific insulation, protection, and grounding requirements that steel angles do not fulfill. To ensure the integrity and efficiency of electrical installations, it is crucial to employ appropriate electrical conduits that satisfy the necessary safety standards.

Q:What are the different types of steel angle profiles?: There are several different types of steel angle profiles, including equal angle, unequal angle, L-shaped angle, and structural angle. Each profile has its own specific dimensions and uses in various applications.
