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, making them suitable for holding and securing pipes in various applications.

Q: What are the common methods of surface finishing for steel angles?: The common methods of surface finishing for steel angles include galvanizing, painting, powder coating, and shot blasting.

Q: Can steel angles be used for framing purposes?: Yes, steel angles can be used for framing purposes. Steel angles are commonly used in construction and engineering to provide structural support and stability. They are often used to create frames for buildings, bridges, and other structures. Steel angles can be easily welded or bolted together to form a strong and rigid frame. They are versatile and can be used in various framing applications, such as supporting walls, beams, and roofs. Additionally, steel angles are durable and have high strength-to-weight ratio, making them ideal for framing purposes.

Q: Are steel angles affected by temperature changes?: Yes, steel angles are affected by temperature changes. Steel has a coefficient of thermal expansion, meaning it expands when exposed to higher temperatures and contracts when exposed to lower temperatures. These temperature changes can cause the steel angles to expand or contract, potentially leading to dimensional changes and structural stress.

Q: Do steel angles have a smooth or textured surface?: Steel angles generally possess a textured exterior, which is formed when the steel is either hot-rolled or cold-formed into the angled shape during the manufacturing process. As a consequence, the steel angles acquire a slightly uneven or knobby surface, enhancing their ability to offer improved grip and stability in diverse applications. Furthermore, this texture serves to deter objects from slipping or sliding when they come into contact with the steel angles. Nevertheless, it should be noted that the degree of texture can differ based on the particular manufacturing technique employed and the intended purpose of the steel angles.

Q: What are the cost considerations for using steel angles?: The cost considerations for using steel angles primarily include the price of the raw material itself, transportation costs, and any additional processing or fabrication expenses. Other factors to consider are the required quantity, size, and complexity of the angles, as these can impact the overall cost. Additionally, market demand, availability, and fluctuations in steel prices can influence the cost of using steel angles. It is also important to account for any potential maintenance or corrosion protection expenses over the lifespan of the steel angles.

Q: What are the different methods of connecting steel angles to other structural elements?: Different methods exist for connecting steel angles to other structural elements, depending on the specific application and load requirements at hand. One method commonly employed is welding, which involves the fusion of the steel angle to the other structural element through the application of intense heat. This results in a robust and enduring connection capable of withstanding high loads. Welding proves particularly useful when a permanent connection is necessary and substantial load requirements are present. Another method is bolting, wherein bolts and nuts are utilized to secure the steel angle to the other structural element. This approach allows for easy disassembly and reassembly if required, offering greater flexibility compared to welding. Bolting is typically chosen when an adjustable connection is desired or when the load requirements are relatively lower. Riveting represents an additional option for connecting steel angles to other structural elements. This method entails inserting a metal pin, known as a rivet, through aligned holes in both the steel angle and the other element, with the end of the rivet deformed to secure it in place. Riveting delivers a sturdy and dependable connection, although it may demand more time and labor compared to welding or bolting. Additionally, adhesive bonding can also be employed to connect steel angles to other structural elements. This technique utilizes specialized adhesives capable of bonding the surfaces of both the steel angle and the other element together. Adhesive bonding provides a strong and uniform connection, making it ideal for applications where aesthetics matter or when joining dissimilar materials is necessary. In summary, the various methods for connecting steel angles to other structural elements encompass welding, bolting, riveting, and adhesive bonding. The choice of method relies on factors such as load requirements, desired flexibility, ease of assembly and disassembly, and the specific application at hand.

Q: Can steel angles be drilled or machined?: Yes, steel angles can be drilled or machined. Due to their structural properties, steel angles can be easily drilled or machined to create holes or cut into desired shapes, making them versatile for various applications.

Q: Can steel angles be cut to custom lengths?: Indeed, custom lengths can be achieved when cutting steel angles. Steel angles, also referred to as angle irons, are multifunctional structural elements widely utilized in both construction and manufacturing. Although they are obtainable in different standard sizes, they can also be tailored to meet specific length specifications. This can be accomplished by utilizing cutting tools like saws or shears to trim the steel angle to the desired measurement. The capability to customize steel angles to unique lengths renders them apt for a diverse array of applications, as they can be adjusted to suit precise design necessities.

Q: How do steel angles perform under impact or dynamic loading conditions?: Steel angles are known for their excellent performance under impact or dynamic loading conditions. Their shape provides structural stability and resistance to bending, making them highly effective in withstanding sudden forces and vibrations. The high strength of steel angles allows them to absorb energy and distribute it evenly, reducing the risk of deformation or failure. Overall, steel angles are reliable and dependable in demanding situations with impact or dynamic loading.
