1. Structure of Steel Bar in Angle Shape Description:

Steel bar in angle shape is a main kind of structure steel and the section is like a letter L. We use steel bar in angle shape for structure construction. Steel bar in angle shape 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 bar in angle shape.

2. Main Features of Steel Bar in Angle Shape:

• 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.

While these may not affect the angle's strength significantly, they can impact its appearance and corrosion resistance. 2. Warping: Steel angles can bend or distort along their length, either during manufacturing or as a result of improper handling or storage. Warped angles may not fit properly in applications that require precise dimensions. 3. Dimension flaws: Steel angles should adhere to specific dimensions and tolerances. However, defects like undersized or oversized legs, unequal lengths, or inconsistent thickness can occur. These flaws can cause installation issues or compromise the angle's structural integrity. 4. Lack of straightness: Steel angles should be straight along their entire length to ensure proper alignment and load distribution. However, they can sometimes exhibit a lack of straightness, known as bowing or crooking. This defect makes it difficult to accurately align angles and may result in uneven stress distribution. 5. Internal cracks: Cracks inside the steel angle are a major concern as they weaken its strength and load-bearing capacity. These cracks can occur during manufacturing due to improper cooling or quenching processes, or they can be a result of excessive stress or corrosion.
