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 are the different methods of surface galvanizing for steel angles?: Steel angles can be surface galvanized using various methods, each with its own benefits and uses. Here are some commonly employed techniques: 1. Hot-dip galvanizing: The most widely utilized method involves immersing steel angles in molten zinc, forming a strong bond with the surface. This process offers exceptional corrosion protection and durability, making it suitable for a wide range of applications. 2. Electro-galvanizing: This method involves electrodepositing a thin layer of zinc onto the steel angle's surface. It is a controlled process that provides a smoother and more even coating. Electro-galvanizing is often used for decorative purposes or when a thinner coating is sufficient. 3. Sherardizing: This method entails coating the steel angles with a mixture of zinc dust and proprietary filler materials, such as aluminum or iron powder. The coated angles are then heated in a furnace, causing zinc to diffuse into the steel's surface, forming a durable alloy layer. Sherardizing is ideal for applications requiring high resistance to wear and abrasion. 4. Mechanical galvanizing: Also known as centrifuge galvanizing, this method involves tumbling steel angles in a drum or barrel with zinc powder and glass beads. The tumbling action helps zinc powder adhere to the surface, creating a protective coating. Mechanical galvanizing is commonly used for small or intricate parts that are challenging to galvanize with other methods. 5. Zinc-rich paint: Although not a conventional galvanizing method, zinc-rich paint can offer similar corrosion protection. It involves applying a paint or coating with a high concentration of zinc particles to the steel angle's surface. These zinc particles act as sacrificial anodes, corroding instead of the steel and safeguarding against rust and corrosion. These methods represent just a few options for surface galvanizing steel angles. The choice of technique depends on factors such as desired corrosion protection, specific application requirements, and cost considerations. Consulting with a galvanizing professional is crucial to determine the most suitable method for your needs.

Q: What is the cost of a steel angle?: The cost of a steel angle can vary depending on various factors such as size, thickness, and market conditions. It is best to check with local suppliers or online retailers to get an accurate and up-to-date price for a specific steel angle.

Q: Can steel angles be used for manufacturing safety barriers?: Yes, steel angles can be used for manufacturing safety barriers. Steel angles are commonly utilized due to their structural strength, durability, and ability to withstand impact. Their L-shape design allows for easy installation and provides stability, making them suitable for constructing safety barriers in various settings such as highways, construction sites, and industrial facilities.

Q: What are the different corrosion protection methods for steel angles?: There are several corrosion protection methods for steel angles, including galvanization, powder coating, paint coating, and epoxy coating.

Q: What are the common design codes and standards for steel angles?: The specific application and industry requirements determine the common design codes and standards for steel angles. Various recognized design codes and standards are applicable to steel angles, including: 1. The American Institute of Steel Construction (AISC) offers design specifications and standards for structural steel construction, including angles. The AISC Steel Construction Manual provides guidance on designing steel structures and selecting steel angles. 2. The American Society for Testing and Materials (ASTM) develops and publishes technical standards for different materials, including steel. ASTM A36/A36M is a commonly referenced standard for carbon structural steel, including angles. It specifies requirements for chemical composition, mechanical properties, and testing methods. 3. The European Norm (EN) specifies technical delivery conditions for structural steel products. EN 10025-2 covers non-alloy structural steels, including angles, and provides requirements for chemical composition, mechanical properties, and tolerances. 4. The British Standards Institution (BSI) publishes standards related to steel angles, such as BS EN 10056-1. This standard details the dimensions and tolerances for hot-rolled equal and unequal steel angles. 5. The Canadian Standards Association (CSA) provides guidance for steel design and construction in Canada. CSA G40.21 is a widely used standard that covers requirements for general structural steel, including angles. It is important to note that these examples represent common design codes and standards for steel angles. Depending on the project and location, additional local or industry-specific codes and standards may need to be considered. Consulting a structural engineer or referring to relevant design codes and standards is crucial for ensuring compliance and safety in steel angle design and construction.

Q: What is the typical width of a steel angle?: The typical width of a steel angle can vary depending on its intended use and the specific requirements of the project. However, in general, steel angles are available in a wide range of sizes and dimensions. Commonly, the width of a steel angle can range from 1 inch to 8 inches or more. It is important to consult the relevant industry standards and specifications to determine the appropriate width for a specific application.

Q: What are the common methods of surface preparation for steel angles?: Common methods of surface preparation for steel angles include abrasive blasting, such as sandblasting or shot blasting, to remove rust, scale, and contaminants from the surface. Chemical cleaning can also be used to remove oils, greases, and other organic materials. Additionally, mechanical cleaning methods like wire brushing or grinding can be employed to smooth out rough surfaces and remove any remaining debris.

Q: Can steel angles support heavy machinery or equipment?: Steel angles possess the capability to uphold substantial machinery or equipment. Their robustness and endurance make them a prevalent choice in construction and engineering. Typically, hot-rolled steel is used in their production, allowing them to endure formidable loads and forces. These steel angles offer both structural support and stability, rendering them suitable for bolstering heavy machinery or equipment. They are frequently employed as frames or brackets to secure and maintain weighty objects. Furthermore, steel angles can be welded or bolted together to construct a sturdy and steadfast foundation for bulky machinery. Overall, steel angles emerge as a reliable option for supporting heavy machinery or equipment owing to their capacity to bear high loads and their structural integrity.

Q: What is angle flower? Is it the same as angle iron?: The angle iron is the foundation of the angle steel and is punched out through the holes,

Q: What is the weight of a steel angle?: The weight of a steel angle depends on its dimensions and density. To calculate the weight, one needs to know the length, width, and thickness of the steel angle. By multiplying the volume of the angle (length x width x thickness) by the density of steel, one can determine its weight. The density of steel is typically around 7.85 grams per cubic centimeter. Therefore, the weight of a steel angle can be calculated using the formula: weight = volume x density.
