Product Description:

1. Structure of Steel Equal Angle Bar Description:

Steel equal angle bar is a main kind of structure steel and the section is like a letter L. We use steel equal angle bar for tower construction. Steel equal angle bar can be erected as soon as the materials are delivered on site. High strength, stiffness, toughness, and ductile properties are advantages of this kind of steel equal angle bar.

2. Main Features of Steel Equal Angle Bar:

• Strength - Having high strength, stiffness, toughness, and ductile properties, structural steel is one of the most commonly used materials in commercial and industrial building construction.

• Constructability - Steel equal angle Bar can be developed into nearly any shape, which are either bolted or welded together in construction. Structural steel can be erected as soon as the materials are delivered on site, whereas concrete must be cured at least 1–2 weeks after pouring before construction can continue, making steel a schedule-friendly construction material.

• Fire resistance - Steel is inherently a noncombustible material. However, when heated to temperatures seen in a fire scenario, the strength and stiffness of the material is significantly reduced. The steel equal angle bar can be enveloped in sufficient fire-resistant materials, increasing overall cost of steel structure buildings.

③What is the difference between steel angle bar and traditional material?

Steel equal angle bar differs from concrete in its attributed compressive strength as well as tensile strength.

Q: How do you calculate the maximum allowable stress for a steel angle?: The maximum allowable stress for a steel angle can be calculated by dividing the ultimate tensile strength of the steel by a factor of safety. This ensures that the stress on the angle remains below its capacity to prevent failure or deformation.

Q: How do you prevent corrosion between steel angles and other materials?: There are several effective measures that can be taken to prevent corrosion between steel angles and other materials: 1. To create a barrier between the steel and surrounding materials, protective coatings such as paint, epoxy, or galvanization can be applied. This prevents direct contact and reduces the risk of corrosion. 2. Insulating materials like rubber or plastic pads or sleeves can be used to separate the steel angles from other materials. This prevents direct contact and minimizes the chances of corrosion. 3. A cathodic protection mechanism can be established by installing sacrificial anodes or using impressed current systems. This creates an electrical current that counteracts the corrosion process, protecting the steel angles. 4. Regular inspection and maintenance of the steel angles are crucial to promptly identify any signs of corrosion and take appropriate actions. This includes cleaning the surfaces, repairing damaged coatings, and replacing corroded parts. 5. Proper drainage is essential to prevent moisture accumulation around the steel angles, which can accelerate corrosion. Designing and installing drainage systems correctly can prevent water or corrosive substances from pooling around the steel angles. 6. If the steel angles are exposed to chemicals or corrosive substances, it is important to choose materials that are resistant to corrosion. This may involve using stainless steel or other corrosion-resistant alloys to withstand exposure to specific chemicals. By implementing a combination of protective coatings, insulation, cathodic protection, regular maintenance, proper drainage, and material selection, corrosion between steel angles and other materials can be effectively prevented. This ensures the longevity and structural integrity of the steel angles.

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: Are steel angles resistant to extreme weather conditions?: Yes, steel angles are highly resistant to extreme weather conditions. They have excellent durability and can withstand harsh weather elements such as heavy rain, strong winds, and extreme temperatures without any significant damage or deterioration.

Q: Are steel angles resistant to dynamic loads?: Yes, steel angles are generally resistant to dynamic loads. Steel is a strong and durable material that can withstand various types of loads, including dynamic loads. Dynamic loads refer to forces or loads that change in magnitude or direction over time, such as impact loads, vibrations, or seismic forces. Steel angles, also known as angle irons or L-shaped structural steel, are commonly used in construction, engineering, and manufacturing industries due to their high strength-to-weight ratio and versatility. They can effectively distribute and transfer loads, providing stability and support to structures. The resistance of steel angles to dynamic loads is attributed to their inherent properties, such as high tensile strength, excellent ductility, and toughness. These properties allow steel angles to absorb and dissipate energy from dynamic loads, minimizing the risk of structural failure or damage. Moreover, steel angles can be further reinforced through various techniques, such as welding, bolting, or bracing, to enhance their resistance to dynamic loads. By properly designing and implementing these reinforcement measures, steel angles can be tailored to specific dynamic load requirements, ensuring the structural integrity and safety of the overall system. However, it is important to note that the resistance of steel angles to dynamic loads may depend on several factors, including the specific grade and quality of the steel, the dimensions and configuration of the angle, the magnitude and frequency of the dynamic loads, and the overall design and construction of the structure. Therefore, it is crucial to consult with structural engineers and adhere to applicable building codes and standards to ensure the appropriate selection and implementation of steel angles for dynamic load applications.

Q: How do you store and transport steel angles?: Steel angles can be stored by stacking them horizontally on a flat and level surface, ensuring they are supported evenly to prevent deformation. To transport steel angles, they can be loaded onto flatbed trucks or trailers, securely strapped or chained to prevent movement during transit. Alternatively, they can be bundled together and lifted by cranes or forklifts, ensuring proper balancing and securing the bundle for safe transportation.

Q: What is the maximum load capacity for a curved steel angle?: The maximum load capacity for a curved steel angle would depend on various factors such as the dimensions of the angle, the type of steel used, and the specific application. It is best to consult engineering specifications or consult a structural engineer for an accurate determination of the maximum load capacity.

Q: Can steel angles be used for staircases?: Yes, steel angles can be used for staircases. Steel angles are commonly used as structural supports in construction, including for staircases. They provide strength and stability to the staircase structure and can be designed to meet specific load-bearing requirements.

Q: Can steel angles be used for equipment racks or shelving?: Equipment racks or shelving can indeed utilize steel angles. The robustness, endurance, and adaptability of steel angles make them widely employed in construction and fabrication. These angles offer structural reinforcement and steadiness, rendering them perfect for crafting resilient equipment racks or shelving units. By welding or bolting steel angles together, a sturdy framework can be created to hold an assortment of items, including weighty machinery, tools, or storage containers. Moreover, the flexible design of steel angles permits effortless customization and adjustment of shelf heights, making them suitable for accommodating diverse sizes and types of objects. In conclusion, steel angles are a dependable choice for constructing equipment racks or shelving systems that necessitate strength, stability, and longevity.

Q: How are steel angles welded or joined together?: Steel angles are commonly welded or joined together using different welding techniques. The most common method is by using arc welding, which includes processes like shielded metal arc welding (SMAW), gas metal arc welding (GMAW), and flux-cored arc welding (FCAW). In shielded metal arc welding, an electric arc is created between a coated electrode and the steel angle, melting the metals and forming a weld joint. Gas metal arc welding utilizes a continuous wire electrode and a shielding gas, such as argon or a mixture of argon and carbon dioxide, to protect the weld from atmospheric contaminants. Flux-cored arc welding uses a hollow wire electrode with flux inside, which creates a shielding gas and slag to protect the weld. Another method for joining steel angles is by using resistance welding. This technique involves applying pressure and passing an electric current through the joint area, which generates heat and forms a weld. Resistance welding methods commonly used for steel angles include spot welding and seam welding. Additionally, steel angles can be joined together through stud welding. Stud welding involves placing a threaded or unthreaded stud against the steel angle and using an arc welding process to fuse the stud to the angle. It is important to note that the specific welding or joining method used for steel angles depends on factors such as the thickness and type of steel, the desired strength of the joint, and the application requirements.
