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 in electrical applications?: Yes, steel angles can be used in electrical applications. They are often used as structural supports or brackets for mounting electrical components, conduit, or cable tray systems. Steel angles provide strength and stability, making them suitable for various electrical applications in both residential and commercial settings.

Q: Can steel angles be used in the construction of pedestrian bridges?: Yes, steel angles can be used in the construction of pedestrian bridges. Steel angles are commonly used in construction due to their strength and durability. They can be used to provide structural support and stability to the pedestrian bridge, as well as to create frames, beams, and trusses. Steel angles can be easily welded or bolted together, allowing for flexibility in design and construction. Additionally, steel angles can be galvanized or coated to increase their resistance to corrosion, making them suitable for outdoor applications such as pedestrian bridges. Overall, steel angles are a versatile and reliable choice for constructing pedestrian bridges.

Q: Are steel angles suitable for outdoor furniture?: Steel angles are indeed appropriate for outdoor furniture. Steel is known for its durability and strength, enabling it to endure diverse weather conditions. This quality makes it an exceptional selection for outdoor furniture. Steel angles contribute to stability and structural support, guaranteeing that the furniture can bear heavy loads and remain firm. Furthermore, when properly treated, steel is resistant to rust and corrosion, which is crucial for outdoor furniture exposed to moisture and changing weather. In addition, steel angles offer a sleek and contemporary aesthetic, enabling versatile design possibilities for outdoor furniture. In summary, the durability, strength, and resistance to environmental elements make steel angles a dependable and long-lasting option for outdoor furniture.

Q: How do you connect steel angles to other structural members?: Steel angles can be connected to other structural members through various methods, such as welding, bolting, or using connector plates.

Q: Can steel angles be used for framing windows and doors?: Yes, steel angles can be used for framing windows and doors. Steel angles provide structural support and stability, making them suitable for framing openings such as windows and doors in construction projects.

Q: Are steel angles available in pre-galvanized form?: Steel angles are indeed available in a pre-galvanized state. Before being shaped into angles, these steel angles have been coated with a layer of zinc. This particular coating serves as a shield against corrosion, which makes pre-galvanized steel angles highly suitable for outdoor and high-moisture environments. Moreover, the pre-galvanized coating enhances the aesthetics of the steel angles, imparting a shiny and metallic look. Due to their strength, durability, and ability to resist corrosion, pre-galvanized steel angles find wide usage in construction, infrastructure projects, and various industrial applications.

Q: How do you calculate the radius of gyration for a steel angle?: The radius of gyration for a steel angle can be calculated using the formula: Radius of Gyration = √(Moment of Inertia / Area) The Moment of Inertia can be determined by considering the shape and dimensions of the steel angle. The Area is the cross-sectional area of the steel angle. By plugging in these values into the formula, the radius of gyration can be calculated.

Q: How do steel angles perform in terms of electromagnetic shielding?: Steel angles are known to be effective in terms of electromagnetic shielding. This is primarily due to their high electrical conductivity and magnetic permeability. These properties allow steel angles to effectively redirect or absorb electromagnetic waves, thereby reducing their impact on nearby electronic devices or sensitive equipment. The shape and geometry of steel angles also contribute to their shielding capabilities, as they can be strategically positioned to create barriers or enclosures that block or divert electromagnetic fields. Additionally, the thickness or gauge of the steel angle can further enhance its shielding performance. Overall, steel angles are widely used in various applications where electromagnetic interference needs to be minimized or controlled, such as in construction, telecommunications, electronics, and automotive industries.

Q: How do you calculate the axial compression capacity of a steel angle?: To calculate the axial compression capacity of a steel angle, you would need to consider several factors such as the dimensions and properties of the angle, the material properties, and the boundary conditions. The calculation typically involves determining the slenderness ratio, which is the ratio of the length of the angle to its thickness. This ratio helps determine whether the angle will fail in compression or buckling. The axial compression capacity can then be calculated using relevant design codes or formulas, taking into account factors such as the yield strength of the material and any additional considerations specific to the application.

Q: What are the different methods for protecting steel angles from corrosion?: There are several methods available for protecting steel angles from corrosion. 1. Galvanization: Galvanization is a widely used method where a layer of zinc is applied to the surface of the steel angle. This zinc layer acts as a sacrificial anode, meaning it corrodes first before the steel, protecting it from rust. This method provides excellent protection and is commonly used in outdoor applications such as construction and infrastructure. 2. Paint coating: Applying a paint coating to the steel angle can provide an effective barrier against corrosion. The paint forms a protective layer that prevents moisture and oxygen from reaching the steel surface, thus inhibiting the corrosion process. It is important to use high-quality, corrosion-resistant paints for long-term protection. 3. Powder coating: Powder coating involves applying a dry powder to the steel angle which is then cured at high temperatures. This creates a hard, durable, and protective layer on the surface. Powder coating provides an attractive finish and excellent resistance to corrosion, making it suitable for both indoor and outdoor applications. 4. Stainless steel: Using stainless steel angles is another method for protecting against corrosion. Stainless steel contains chromium, which forms a passive oxide layer on the surface that acts as a protective barrier against corrosion. This makes stainless steel highly resistant to rust, making it ideal for applications where corrosion is a concern. 5. Cathodic protection: Cathodic protection is a technique used to protect steel angles by making them the cathode in a corrosion cell. This is achieved by connecting the steel angle to a sacrificial anode, such as zinc or aluminum, or by using impressed current systems. By doing so, the anode corrodes instead of the steel, effectively protecting it from corrosion. It is worth noting that the selection of the appropriate method for protecting steel angles from corrosion depends on various factors such as the intended application, environmental conditions, and budget constraints. Consulting with corrosion experts and considering the specific requirements of the project is advisable to ensure the most suitable method is chosen.
