Steel angles are among the most important construction materials in the construction and infrastructural development industry. Construction work of residential, commercial, or industrial nature, if either of the two cases, with varying steel angle sizes and how to use them in the best possible manner can make or break a job. Steel angles, angle bars, or L-steel bars are used in the support and reinforcement of structures so that the frames of steel or concrete are capable of bearing loads imposed on them.
What Are Steel Angles and Why Do They Need to Be Used in Construction Activity?
Steel angles are L-steel bars, and they are used mainly in supporting loads while building buildings. They are made by bending steel plates in perpendicular to one another. Steel angles are of different sizes, strengths, and forms, but all are utilized based on a specific need of a building. The use of the appropriate size of the steel angle can’t be overemphasized because it is for the sake of the overall strength, stability, and safety of a building.
The strength, resistance to corrosion, and hardness of steel angle are the reasons why it is used as a fundamental material for machine frames, bridges, construction frames, and even ships. But then again, with so many sizes and grades available, it might be daunting for engineers, architects, and contractors to determine the most appropriate one.
What Is the Best Steel Angle Size for Your Structural Project?
Choosing the most appropriate steel angle size is a matter of project specification, be it carrying capacity, environmental factor, or expense. Steel angle sizes found in the marketplace are varied and are largely a matter of thickness, width, or length.
Most Common Steel Angle Sizes Found Appropriate for Use in Structures
The most common steel angle sizes to be utilized in structures are:
- 20x20mm to 200x200mm:These are used in small to medium-sized structural members, i.e., framing or bracing. Lighter size is used in light-duty application like frames of a building, while the heavier sizes are used in heavy load-carrying structures.
- 250x250mm to 400x400mm:Heavy-duty angle steels, which are utilized fairly commonly in industry. These are utilized quite commonly to support bridges, steel frame of large buildings, and in machinery of industry.
How Steel Angle Sizes Affect Structural Performance?
The structural integrity of the building will be determined by the size of the steel angle. In choosing the size of the steel angle, one will need to think about the horizontal load and the vertical load that the angle will be supporting. Increasing loads and increasing building strength will be best served by bigger angles, for instance. Smaller angles will do otherwise where there is minimal load.
How to Choose the Right Size of Steel Angle for Your Building Project?
The choice of the right size of steel angle for a project is at the mercy of the project’s load requirements, structural design, and environmental conditions. The controlling parameters should be controlling your choice:
- Load-Bearing Requirement:Most important factor while choosing sizes of steel angles. Small angles of 20x20mm or 40x40mm would suffice for light-duty applications. Steel angles of sizes such as 250x250mm or 300x300mm are to be employed in heavy-duty applications.
- Environmental Conditions: If the project is located in a coastal or wet region, painting or galvanizing of corrosion-resistant steel angle coating is required. Utilize a corrosion-resistant steel grade or surface treatment offered by manufacturers such as Sunrise New Material.
- 3. Project Budget:Steel angles are costlier as they grow larger and heavier. They are, however, worth it in the long run in terms of fewer maintenance needs and longer structural life.
Real-Life Example: Steel Angle Structural Works
Sunrise New Material Co., Ltd. supplied steel angles to Vietnam’s Long Thanh International Airport giant project.
These A36 and A572 Gr.60 steel angles provided by this project belonged to the steel support frame system of the airport and were required to be sturdy enough to bear the huge weight of the structure in addition to the environmental load of seaside exposure. Sunrise’s A36 and A572 Gr.60 steel angles were precisely what was required for these high-demand applications, both affordable and durable.
What Standards and Regulations Apply to Steel Angle in Construction?
Steel angle items must adhere to some of the requirements and specifications as far as possible regarding safety and usage in building construction. National and international standards for most countries control steel angles, including steel material size, material, and testing.
- ASTM A36/A36M:Identifies material characteristics of A36 steel angles.
- ISO 630:Identifies general product specification for rolled structural steel products like angle bars.
- EN 10056: Specifies the dimensions and tolerances of steel construction angles.
