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
