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: How do you calculate the moment of inertia for a steel angle?: To calculate the moment of inertia for a steel angle, you need to know the dimensions and properties of the angle. The moment of inertia can be calculated using the formula: I = (1/12) * b * h^3, where I is the moment of inertia, b is the base width of the angle, and h is the height of the angle.

Q: Can steel angles be used for storage racks?: Yes, steel angles can be used for storage racks. Steel angles are commonly used in the construction of storage racks due to their strength, durability, and ability to support heavy loads. They provide stability and structural integrity, making them suitable for storing various items in a safe and organized manner.

Q: What is the maximum cantilever length for a steel angle?: The maximum cantilever length for a steel angle depends on various factors such as the material strength, the angle's dimensions, and the load it needs to support. Steel angles are commonly used as structural elements in construction and can be designed to support different loads based on their size and configuration. In general, the maximum cantilever length for a steel angle is determined by its ability to resist bending moments and deflection. Bending moments occur when a load is applied to the free end of the cantilever, causing the angle to bend. Deflection is the amount of bending or sagging that occurs under a specific load. To determine the maximum cantilever length, engineers consider the moment of inertia, which is a measure of the angle's resistance to bending, as well as the yield strength of the steel. The moment of inertia is affected by the angle's dimensions, such as the width and thickness of the flanges and the length of the legs. Additionally, the design codes and standards specific to the project or application must be followed to ensure safety and compliance. These codes provide guidelines on the maximum allowable bending stress and deflection limits for steel angles in different loading conditions. In summary, the maximum cantilever length for a steel angle depends on its material strength, dimensions, and the load it needs to support. It is determined through calculations considering the moment of inertia, yield strength, and compliance with relevant design codes and standards.

Q: Can steel angles be used in pedestrian bridges?: Yes, steel angles can be used in pedestrian bridges. Steel angles provide structural support, stability, and durability to the bridge, making them a commonly used material in bridge construction.

Q: How do you calculate the section modulus of a steel angle?: To calculate the section modulus of a steel angle, you need to know the dimensions and properties of the angle. The section modulus is a measure of the strength of a structural member and is used to determine its resistance to bending. The formula to calculate the section modulus of a steel angle is: Section Modulus (Z) = (Width of the angle * Height of the angle^2) / 6 In this formula, the width of the angle refers to the distance between the two legs, while the height of the angle is the length of one leg. The section modulus is typically expressed in cubic inches or cubic centimeters. To calculate the section modulus, first measure the width and height of the angle. Then substitute these values into the formula to find the section modulus. This value will give you an indication of the strength and stiffness of the steel angle, which can be used in structural design and analysis.

Q: 100 x 100 x 10 equal angle steel, per meter weight?: The angle iron can be made up of different force components according to the different structure, and can also be used as the connecting piece between the components. Widely used in a variety of architectural and engineering structures, such as beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container frame and warehouse shelves steel base.

Q: Can steel angles be used for machine frames?: Machine frames can indeed utilize steel angles. Steel angles are frequently employed in construction and engineering due to their robustness, adaptability, and affordability. In the context of machine frames, steel angles offer structural reinforcement and stability. By welding or bolting them together, a firm framework capable of withstanding substantial loads and vibrations can be effortlessly created. Additionally, the angular form of steel angles facilitates convenient attachment of other components or accessories. All in all, steel angles are widely favored for machine frames owing to their endurance and compatibility with diverse industrial uses.

Q: How can steel angles be cut to size?: There are various methods available for cutting steel angles to size, depending on the tools and equipment that are accessible. One common approach involves utilizing a power saw equipped with a metal cutting blade. This particular saw allows for clean and precise cuts, enabling accurate sizing of the steel angles. Another option involves using an angle grinder with a cutting wheel attachment. This handheld tool can be easily maneuvered to cut through the steel angles, although the resulting cut may not be as clean as that achieved with a power saw. For smaller and thinner steel angles, a hacksaw can also be utilized. Although this manual tool requires more effort, it can still deliver accurate cuts. Furthermore, certain fabrication shops may possess more specialized cutting equipment, such as a plasma cutter or a water jet cutter, which offer even greater precision and efficiency. Ultimately, the choice of method for cutting steel angles to size will depend on the specific requirements and available resources.

Q: Can steel angles be used for stair stringers?: Yes, steel angles can be used for stair stringers. Steel angles are commonly used in construction for their strength and durability. When used as stair stringers, steel angles provide the necessary support and stability for the stairs. They can be easily cut and welded to the desired shape and size, making them a versatile option for stair construction. Additionally, steel angles are resistant to rot, termites, and other forms of damage, ensuring the longevity of the stair structure. However, it is important to consult with a structural engineer or a professional contractor to ensure that the steel angles meet the specific requirements and load-bearing capacity for the intended stair design.

Q: Can steel angles be used for artistic or decorative applications?: Yes, steel angles can be used for artistic or decorative applications. They can be shaped, welded, or manipulated to create unique designs and structures. Their strength and durability make them suitable for various artistic projects, such as sculptures, installations, or architectural elements.
