Full Range of Retaining Wall Steel In-Stock

Universal Column (H Beam)
Universal Beam (I Beam)
PFC (C Channel)
Universal Beam – (I- Beam)
Universal Beams (UB), (also called I-beams) are commonly used for smaller retaining walls (typically under 1 metre) due to their strong vertical load-bearing capacity while being lightweight and cost-effective. They are suitable for projects where space is limited, and the loads are relatively moderate.
I-Beam 100 UB Sizes:
Standard Lengths: 6m (can be cut to length)
Concrete Sleper Width: 75-80mm.
H-Beam 150 UC Sizes:
Standard Lengths: 6m (can be cut to length)
Concrete Sleper Width: 100mm.
Universal Column – (H- Beam)
Universal Columns (UC) (also called H-beams) are perfect for higher retaining walls (over 1 metre) that need to support heavier loads and withstand greater lateral pressure from soil. Their wider flanges provide better weight distribution, making them more suitable for significant structural requirements.
H-Beam 100 UC Sizes:
Standard Lengths: 6m (can be cut to length)
Concrete Sleper Width: 75-80mm.
H-Beam 150 UC Sizes:
Standard Lengths: 6m (can be cut to length)
Concrete Sleper Width: 100mm.
C- Channel (PFC)
C-Channel, (also called PFC) is primarily used as an end cap for retaining walls. Its C-shaped cross-section effectively distributes loads and reinforces wall ends, preventing soil erosion and maintaining structural integrity. C-channel enhances the strength and durability of retaining walls while providing a clean, professional appearance.
C Channel - 100 PFC Sizes:
Standard Lengths: 6m (can be cut to length)
Concrete Sleper Width: 75-80mm.
C Channel - 150 PFC Sizes:
Standard Lengths: 6m (can be cut to length)
Concrete Sleper Width: 100mm.
