A PEB Mild Steel Beam (345 MPa) is a high-strength structural member widely used in Pre-Engineered Building (PEB) systems due to its excellent load-bearing capacity, durability, and cost efficiency. Manufactured from mild steel with a minimum yield strength of 345 megapascals, these beams ensure superior structural performance while maintaining flexibility in design.

Key Features

• High Yield Strength (345 MPa): Provides strong resistance against bending, shear, and deformation under heavy loads.

• Excellent Weldability & Fabrication: Mild steel allows easy cutting, welding, drilling, and connection with PEB components.

• Enhanced Structural Stability: Ideal for long-span applications with minimal deflection.

• Corrosion-Resistant Options: Available with galvanization, primer coating, or paint for long-term protection.

• Lightweight Yet Strong: Reduces overall project cost through optimized steel consumption.

Applications

PEB 345 MPa beams are commonly used in:

• Industrial sheds & factories

• Warehouses & logistics buildings

• Multi-storey steel structures

• Commercial buildings & showrooms

• Cold-storage and heavy-load structures

• Airport hangars & large-span roofing systems

Technical Specifications

• Material Grade: Mild Steel, 345 MPa yield strength

• Standard Shapes:

  • I-Beams / H-Beams

  • Built-Up Welded Beams

  • Tapered Beams for PEB frames

• Thickness Range: Customizable based on design requirements

• Standards Followed: IS 2062 E350 Grade or equivalent

• Surface Finish:

  • Red oxide primer

  • Galvanized (optional)

  • Powder-coated (on request)

Advantages for PEB Construction

• Suitable for heavy structural loads

• Reduces installation time due to prefabrication

• Enables longer spans without intermediate supports

• Improves seismic and wind load performance

• Ensures long-term reliability and low maintenance

Quality Structural Steel Products supplied by United Steel

Universal Beams and Universal Columns

Rediscover Steel’s extensive network of sites houses a vast inventory of structural steel products, including universal beams (UBs) and universal columns (UCs), essential for construction applications. With in-house processing capabilities like precise cut-to-length, drilling, and more, we ensure your structural needs are met. Universal columns, often referred to as “H” beams due to their shape, are vital for various projects. Similarly, “I” beams or UBs are frequently used in construction.

Welded Beams and Welded Columns

Welded Beams and Welded Columns play a pivotal role in heavy engineering projects, providing crucial support for substantial loads in various infrastructure applications. From bridges and multi-level car parks to mining operations and sports stadiums, these robust structural components find widespread use. United Steel maintains an inventory of welded beams and welded columns in grade 300, with additional options like 300L15, 400, and 400L15 available upon request. We source these products from ACRS certified manufacturers, ensuring adherence to applicable Australian standards. Our services also encompass value-added processing, including beamline solutions and mid-span beam cambering on applicable products.

The significant size of welded beams and columns, in comparison to other structural elements, offers engineers the flexibility to design projects with significantly larger spans, thereby reducing the need for additional support features like piers in road construction. This not only contributes to lighter, more efficient structures but also enables the incorporation of extra floors in buildings, maximising commercial space. In stadium construction, these components find applications in cantilever sections for multi-level seating, awnings, and roofing. Moreover, they prove invaluable in mining infrastructure, serving roles in conveyors, mineral processing, heavy equipment, and materials handling.

United Steel can also source a range of quench and tempered steel plate products often used in mining applications. For tailored solutions matching your project requirements, please consult our expert team.

Tapered Flange Beams

Tapered Flange Beams share the familiar “I” shape of other structural beams, but their distinctive feature lies in the tapered flanges that connect the web section. This unique design imparts enhanced strength and resistance to bending forces. Tapered flange beams frequently serve as cross-sectional components for girders in construction projects and are also employed in the construction of truck trailer bodies.
