2. With bundles and load in 20 feet/40 feet container, or by bulk cargo, also we could do as customer's request.

3. Marks:

Color mark: 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 seismic-resistant structures?
Yes, steel angles can be used in seismic-resistant structures. They are commonly used as structural members in seismic-resistant construction due to their ability to resist lateral forces and provide stability during earthquakes. Steel angles are strong and rigid, making them suitable for withstanding the dynamic loads and vibrations associated with seismic events.
Q: Are there any limitations on the length-to-thickness ratio of steel angles?
Steel angles have limitations on their length-to-thickness ratio, which is also known as the slenderness ratio. This ratio is crucial in determining the structural stability and load-bearing capacity of steel angles. To calculate the slenderness ratio, divide the angle's length by its thickness. In general, steel angles with a higher length-to-thickness ratio are more prone to buckling or failure when subjected to compressive loads. To maintain structural integrity, there are industry standards and guidelines that define the maximum slenderness ratios for steel angles. The specific limitations on the length-to-thickness ratio of steel angles vary based on factors such as the steel type, angle cross-sectional shape, applied load, and intended use. These limitations are typically outlined in engineering codes and standards like the American Institute of Steel Construction (AISC) or Eurocode, which provide design guidelines for various structural components, including steel angles. Adhering to these limitations is crucial to prevent structural failures and ensure the safety and performance of steel angles in different applications. Structural engineers and designers should consult the relevant codes and standards to determine the appropriate length-to-thickness ratio for specific steel angle designs.
Q: What is the difference between the main keel and the angle steel and the channel steel?
Channel steel is a kind of carbon structural steel used for construction and machinery. It is a complex section steel. Its cross section has a groove shape. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing, etc.. In use, it requires better welding, riveting performance and comprehensive mechanical properties. The raw material steel billet for channel steel is carbon or low alloy steel billets with a carbon content of not more than 0.25%. The finished channel steel is delivered by hot forming, normalizing or hot rolling. The specifications are expressed in millimeters of height (H) * leg width (b) * waist thickness (d), such as 100*48*5.3, which means waist height is 100 mm, leg width is 48 mm, waist thickness is 5.3 mm channel, or 10# channel steel. The same height of the channel, if there are several different leg width and waist thickness, also need to add a, B, C on the right side of the model to distinguish, such as 25#a, 25#b, 25#c and so on.
Q: Can steel angles be used for pedestrian bridges or walkways?
Indeed, pedestrian bridges or walkways can utilize steel angles. Construction frequently employs steel angles owing to their robustness, longevity, and adaptability. By means of simple fabrication and welding, steel angles can effortlessly form the desired structural components for bridges and walkways. Bearing exceptional load capacities, steel angles are well-suited for supporting pedestrian traffic. Moreover, steel's corrosion-resistant qualities render it an ideal option for outdoor applications subject to weather exposure. In summary, the reliability and capacity to meet essential structural criteria render steel angles a favored selection for pedestrian bridges and walkways.
Q: Galvanized steel angles under what conditions?
Humid environment
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: Are steel angles suitable for vehicle ramps?
Yes, steel angles are suitable for vehicle ramps. Steel angles provide strength and stability, making them an ideal choice for supporting the weight of vehicles and ensuring safe and durable ramps.
Q: What is the lifespan of steel angles?
The durability and longevity of steel angles can be influenced by several factors, including the quality of the steel, the environmental conditions in which they are used, and the level of maintenance they receive. It is widely recognized that steel angles are highly durable and long-lasting, which is why they are commonly chosen for construction and structural purposes. When high-quality steel angles are manufactured and maintained properly, they can endure for several decades or even longer. However, their lifespan can be significantly reduced by factors such as exposure to harsh weather, corrosive environments, and neglectful maintenance. To ensure the maximum lifespan of steel angles, it is crucial to select the appropriate steel grade for the specific application, carry out proper installation, and regularly inspect and maintain them. This may involve actions such as periodically applying paint or protective coatings to prevent corrosion, conducting routine inspections to detect any signs of wear or damage, and promptly addressing any issues that arise. In conclusion, the lifespan of steel angles can vary, but with adequate care and maintenance, they can last for many years, providing strength and stability to a wide range of structures and applications.
Q: How do you prevent steel angles from twisting?
There are several methods that can be employed to prevent steel angles from twisting: 1. Proper fabrication techniques: Ensure that the steel angles are fabricated accurately and precisely, with straight and square cuts. This will help maintain the structural integrity of the angles and prevent them from twisting. 2. Bracing and supports: Use appropriate bracing and supports during the installation process to provide stability to the steel angles. These can include temporary supports, diagonal bracing, or cross bracing, depending on the specific application. 3. Welding techniques: When joining steel angles together, use proper welding techniques to minimize distortion and twisting. This includes using the correct welding process, ensuring proper heat control, and employing suitable fixturing to hold the angles in place during the welding process. 4. Anchoring methods: Depending on the specific application, anchoring methods such as bolting, screwing, or welding the steel angles to other structural elements can help prevent twisting. These anchoring methods provide additional stability and prevent the angles from rotating or twisting under external forces. 5. Regular inspections and maintenance: Conduct regular inspections to identify any signs of twisting or distortion in the steel angles. If any issues are detected, take immediate corrective action to rectify the problem and prevent further twisting. Overall, a combination of accurate fabrication, proper bracing and supports, appropriate welding techniques, anchoring methods, and regular maintenance can effectively prevent steel angles from twisting and ensure their structural stability.
Q: What are the different types of steel angles used in transmission towers?
There are primarily three types of steel angles used in transmission towers: equal leg angles, unequal leg angles, and back-to-back angles.
