What other Steel Profiles?
Steel profiles, also known as steel sections or structural steel shapes, are specific shapes of steel bars or beams that are designed to have specific cross-sectional configurations.
These profiles are commonly used in construction and engineering applications to provide structural support, distribute loads, and resist bending and other forces.
Steel profiles are produced through rolling or extrusion processes, and each shape has unique properties that make it suitable for various construction and structural applications.
Some common steel profiles include:
- I-Beams (Universal Beams): I-beams have an “I” or “H” shape and are characterized by their wide flanges and narrow web. They provide high strength and stiffness and are commonly used in building construction for vertical support columns and horizontal beams.
- H-Beams (Wide Flange Beams): Similar to I-beams, H-beams have a wider flange and are used for heavier loads and longer spans.
- C-Channels (C-Sections): C-channels have a “C” shape and are used primarily as support or framing elements in various construction projects.
- U-Channels (U-Sections): U-channels have a “U” shape and are often used as vertical support or edging elements.
- Angle Profiles (L-Shaped Sections): Angle profiles have an “L” shape and are commonly used for corner reinforcement or bracing in buildings and structures.
- Square Hollow Sections (SHS): Square hollow sections are square-shaped steel profiles with uniform thickness, used in structural and architectural applications.
- Rectangular Hollow Sections (RHS): Similar to SHS, rectangular hollow sections have a rectangular shape and are widely used in construction and fabrication.
- Circular Hollow Sections (CHS): Circular hollow sections are circular steel profiles with a hollow interior, often used in structural columns and beams.
- T-Profiles (T-Sections): T-profiles have a “T” shape and are used for joining or framing components.
- Z-Profiles (Z-Sections): Z-profiles have a “Z” shape and are used in applications like purlins and girts in building construction.
These steel profiles are manufactured to specific dimensional and material standards, such as those set by the American Society for Testing and Materials (ASTM), European Norms (EN), and other regional or international standards.
Steel profiles are essential components in various construction projects, including building frames, bridges, industrial structures, and infrastructure.
Their design and selection depend on the specific load requirements, architectural design, and engineering specifications of the project.
Steel Sections Grades and Sizes
Steel profiles come in various grades and sizes, each designed for specific structural applications and load-bearing capacities.
The selection of the appropriate grade and size depends on factors such as the intended use, the weight it needs to support, and the environmental conditions it will be exposed to.
Below are some common steel profile grades and typical sizes for specific profiles:
1. I-Beams (Universal Beams):
- ASTM A36: A widely used carbon steel grade with good strength and ductility.
- ASTM A572 Grade 50: A high-strength, low-alloy (HSLA) steel grade with improved formability and weldability.
Typical Sizes (for example):
- W10x33: A W-shaped I-beam with a nominal depth of 10 inches and a weight of approximately 33 pounds per foot.
- W12x53: A W-shaped I-beam with a nominal depth of 12 inches and a weight of approximately 53 pounds per foot.
2. C-Channels (C-Sections):
- ASTM A36: Commonly used for various structural and general construction applications.
Typical Sizes (for example):
- C3x4.1: A C-shaped channel with a nominal depth of 3 inches and a weight of approximately 4.1 pounds per foot.
- C8x11.5: A C-shaped channel with a nominal depth of 8 inches and a weight of approximately 11.5 pounds per foot.
3. Angle Profiles (L-Shaped Sections):
- ASTM A36: Widely used for various construction and structural applications. Typical Sizes (for example):
- L2x2x3/16: An L-shaped angle with legs each measuring 2 inches and a thickness of 3/16 inches.
- L4x4x1/2: An L-shaped angle with legs each measuring 4 inches and a thickness of 1/2 inch. 1. Square Hollow Sections (SHS):
- ASTM A500: Cold-formed welded and seamless carbon steel structural tubing.
Typical Sizes (for example):
- 2x2x1/4: A square hollow section with a 2-inch by 2-inch exterior dimension and a wall thickness of 1/4 inch.
- 4x4x3/8: A square hollow section with a 4-inch by 4-inch exterior dimension and a wall thickness of 3/8 inch.
4. Circular Hollow Sections (CHS):
- ASTM A500: Cold-formed welded and seamless carbon steel structural tubing.
Typical Sizes (for example):
- 2.5″ OD x 0.1875″ Wall: A circular hollow section with an outer diameter of 2.5 inches and a wall thickness of 0.1875 inches.
- 6″ OD x 0.250″ Wall: A circular hollow section with an outer diameter of 6 inches and a wall thickness of 0.250 inches.
These are just a few examples of common steel profile grades and sizes. There are many other sizes available for each profile type, and the availability may vary depending on the manufacturer.
