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 standard sizes of steel angles?: The region and industry dictate the standard sizes of steel angles, although there are widely utilized common sizes. Steel angles generally come in equal leg and unequal leg sizes. Equal leg angles have standard sizes ranging from 20x20mm to 200x200mm, with thicknesses ranging from 3mm to 26mm. Unequal leg angles have one leg longer than the other, and their standard sizes range from 25x16mm to 200x150mm, with thicknesses ranging from 3mm to 15mm. These standard sizes find widespread use in construction, engineering, and manufacturing industries for various purposes, including structural supports, framing, and bracing. It is worth noting that these sizes may differ based on project-specific requirements or industry-regulated standards.

Q: How does the price of steel angles vary based on size and grade?: The price of steel angles can vary based on both the size and grade of the steel. Firstly, the size of the steel angle plays a significant role in determining its price. Generally, larger steel angles tend to be more expensive than smaller ones. This is due to the fact that larger angles require more raw material and involve more manufacturing processes, resulting in higher production costs. As a result, the price of steel angles tends to increase as the size or length of the angle increases. Secondly, the grade of the steel also influences its price. Steel angles are produced in various grades, each offering distinct characteristics and properties. Higher-grade steel angles, such as stainless steel or structural steel, are generally more expensive compared to lower-grade options like mild steel. This is because higher-grade steels often require more advanced manufacturing techniques and superior quality raw materials, which contribute to the higher production costs and subsequently drive up the price. Additionally, factors such as market demand, availability of raw materials, and manufacturing efficiency can also impact the price of steel angles. Fluctuations in demand and supply can lead to price variations, with higher demand often resulting in higher prices. Moreover, the availability and cost of raw materials used to produce steel angles, such as iron ore and scrap metal, can affect the overall price. Lastly, improvements in manufacturing processes and technology can lead to increased efficiency, potentially lowering production costs and influencing the final price of steel angles. In summary, the price of steel angles is influenced by both their size and grade. Larger angles and higher-grade steels tend to be more expensive due to increased production costs. Additionally, market demand, raw material availability, and manufacturing efficiency can also impact the price of steel angles.

Q: What is the angle iron back machine?: With the development of the power industry, the manufacturing level of the power tower is becoming more and more demanding, and the planer processing method can not meet the requirements of production. The company's own design and manufacture of "CB2512" shovel back machine, the use of high-speed milling principle, used for angle steel shovel back process, the tower is the production of angle steel shovel back the first choice of equipment

Q: How do you store steel angles to prevent damage?: Steel angles can be stored to prevent damage by ensuring they are stored in a dry, well-ventilated area, preferably indoors. They should be stacked on a flat surface and separated by wooden or rubber spacers to avoid direct contact and potential scratching. Additionally, storing them in an organized manner, with heavier angles at the bottom and lighter ones on top, can help prevent any potential bending or warping.

Q: Are steel angles suitable for architectural cladding?: Architectural cladding can indeed utilize steel angles effectively. Due to their robustness, strength, and adaptability, steel angles find wide usage in architectural settings. They offer a sturdy framework capable of supporting a range of cladding materials, including metal panels, glass, and composites. Architects can customize steel angles to suit various sizes and shapes, enabling them to achieve desired aesthetics and design specifications. Moreover, steel angles allow for easy fabrication and installation, making them a cost-efficient option for architectural cladding. Nevertheless, when selecting steel angles for cladding applications, it is crucial to consider factors like corrosion resistance, weather resistance, and maintenance requirements.

Q: Can steel angles be used as framing members in buildings?: Yes, steel angles can be used as framing members in buildings. Steel angles are commonly used in structural applications due to their strength, durability, and versatility. They provide excellent support and stability, making them suitable for framing various building elements such as walls, floors, and roofs.

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 corrosive gas or liquid environments?: The strength and versatility of steel angles make them a popular choice for various structural applications. However, their performance in corrosive gas or liquid environments can be impacted by the grade of steel used and the concentration and nature of the corrosive substance. When exposed to corrosive gases or liquids, steel angles can undergo corrosion, leading to a gradual deterioration of their structural integrity. The extent of corrosion depends on factors such as exposure time, temperature, humidity, and the corrosiveness of the gas or liquid. To counteract the effects of corrosion, protective coatings can be applied to steel angles used in corrosive environments. Examples of common protective coatings include galvanization, which involves adding a layer of zinc to the steel surface, as well as epoxy or polyurethane coatings. These coatings create a barrier that prevents direct contact between the corrosive substance and the steel, thereby slowing down the corrosion process. However, it is important to acknowledge that even with protective coatings, steel angles may still experience some level of corrosion over time. The extent of corrosion will depend on the quality and durability of the coating, as well as the regular maintenance and inspection of the steel angles. In extremely aggressive or highly concentrated corrosive environments, steel angles may not be the most suitable choice. In such cases, alternative materials like stainless steel or corrosion-resistant alloys may be more appropriate. In conclusion, the performance of steel angles in corrosive gas or liquid environments is influenced by specific conditions and protective measures in place. Regular inspection, proper maintenance, and the use of suitable coatings are vital for ensuring the longevity and performance of steel angles in corrosive environments.

Q: How do you reinforce a steel angle for added stability?: One way to reinforce a steel angle for added stability is by adding gussets or diagonal braces. These additional elements can be attached to the steel angle to increase its strength and resistance to bending or twisting forces.

Q: Are steel angles resistant to chemicals?: Yes, steel angles are generally resistant to chemicals due to their high durability and corrosion resistance. However, their resistance may vary depending on the specific type of chemical and environment they are exposed to.
