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 flat bars be used for making HVAC systems or components?: Yes, steel flat bars can be used for making HVAC systems or components. Steel flat bars are commonly used in the construction industry due to their strength and durability. They can be used to fabricate various parts of HVAC systems such as ductwork, brackets, supports, and frames. The versatility of steel flat bars allows for customization and the ability to meet specific design requirements. Additionally, steel flat bars have excellent thermal conductivity, which is beneficial for HVAC systems as it helps in the efficient transfer of heat or cold air. Overall, steel flat bars are a suitable material choice for making HVAC systems or components.

Q: How do you join steel flat bars together?: One common method to join steel flat bars together is through welding. This involves melting the edges of the bars and fusing them together using a welding electrode or filler metal. Another option is to use mechanical fasteners such as bolts, screws, or rivets to connect the flat bars. Additionally, steel flat bars can be joined using adhesives specifically designed for metal bonding. The choice of joining method depends on the specific application and desired strength of the connection.

Q: What are the different types of surface finishes for titanium steel flat bars?: Titanium steel flat bars have a variety of surface finishes to choose from. Some commonly used options include: 1. Mill finish: The flat bar is left in its original state after manufacturing, resulting in a rough texture with visible marks. 2. Brushed finish: Also known as satin finish, this technique involves brushing the flat bar with a fine abrasive material to create a smooth and consistent texture with parallel lines. 3. Polished finish: By progressively polishing the flat bar with finer abrasives, a smooth and reflective surface is achieved, providing a shiny and mirror-like appearance. 4. Sandblasted finish: This method entails blasting the flat bar with fine sand or other abrasives at high speed, resulting in a textured and matte appearance with a slightly rough feel. 5. Anodized finish: Through an electrochemical process, a protective oxide layer is formed on the surface of the flat bar. This finish can be achieved in various colors and offers enhanced corrosion resistance and durability. 6. Powder-coated finish: Dry powder is applied to the flat bar's surface and then cured under heat to create a durable and protective coating. A wide range of colors and finishes, including matte, glossy, and textured options, are available. These examples represent only a fraction of the surface finishes available for titanium steel flat bars. The choice of finish depends on the desired appearance, functionality, and specific requirements of the application.

Q: What are the tolerances for steel flat bars?: The tolerances for steel flat bars can vary depending on the specific requirements and industry standards. However, common tolerances for steel flat bars typically include dimensional tolerances such as width, thickness, and length variations. These tolerances are usually specified in terms of a range or a maximum allowable deviation from the specified dimensions. It is important to consult the relevant industry standards or the manufacturer's specifications to determine the specific tolerances for steel flat bars in a particular application.

Q: Are steel flat bars suitable for making agricultural implements?: Yes, steel flat bars are suitable for making agricultural implements. Steel flat bars offer high strength, durability, and resistance to wear and tear, making them ideal for withstanding the demanding conditions and heavy use associated with agricultural tasks. Additionally, their versatility allows for easy customization and shaping to meet specific requirements of different implements.

Q: What are the different methods of surface hardening for steel flat bars?: There are several different methods of surface hardening for steel flat bars, each offering unique advantages and applications. Some of the most common methods include: 1. Flame Hardening: This process involves heating the surface of the steel flat bar with a flame and then quenching it rapidly, resulting in a hardened outer layer while retaining a tough core. Flame hardening is suitable for larger flat bars and offers good wear resistance. 2. Induction Hardening: In this method, an alternating electromagnetic field is used to heat the surface of the steel flat bar, followed by quenching. Induction hardening provides precise control over the hardened depth and is ideal for flat bars with complex geometries or smaller sizes. 3. Nitriding: Nitriding involves exposing the steel flat bar to a nitrogen-rich environment at elevated temperatures. This process forms a hard nitride layer on the surface, providing excellent wear and corrosion resistance. Nitriding is commonly used for flat bars that require superior surface hardness. 4. Carburizing: Carburizing involves heating the steel flat bar in a carbon-rich environment, allowing carbon atoms to diffuse into the surface. The part is then quenched to achieve hardness. Carburizing offers high wear resistance and is suitable for flat bars that require a hardened surface layer. 5. Carbonitriding: This method combines the benefits of both carburizing and nitriding. The steel flat bar is heated in a nitrogen-rich and carbon-rich atmosphere, resulting in a hard surface layer with improved wear and corrosion resistance. Carbonitriding is commonly used for flat bars that require a combination of hardness and toughness. 6. Laser Hardening: Laser hardening utilizes a high-energy laser beam to heat and rapidly cool the surface of the steel flat bar, creating a hardened layer. This process offers precise control over the hardened area and is suitable for flat bars with intricate designs or localized hardening requirements. Each surface hardening method has its own advantages and limitations, and the choice depends on the specific requirements of the steel flat bar application, such as desired hardness, wear resistance, and dimensional complexity.

Q: Can steel flat bars be used in the manufacturing of tools?: Steel flat bars are capable of being utilized in the production of tools.
