Castellation

Castellation is a specialized process where carefully engineered openings or “cells” are cut into steel beams, reducing the beam’s weight while retaining (or sometimes even enhancing) its structural strength. At David Engineering, we leverage cutting-edge technologies and decades of hands-on expertise to create castellated beams that empower architects, engineers, and builders to realize lighter yet robust structural designs.
What is Castellation?
Castellation modifies a standard steel beam by cutting and rejoining it to form octagonal or hexagonal web openings.
This technique:
- Reduces Overall Weight: By removing select material, we keep the beam’s load-bearing capacity high while making it lighter.
- Enhances Strength-to-Weight Ratio: These openings can strengthen the beam in specific orientations, providing better structural performance.
- Expedites Installation: Lighter beams are simpler to transport, handle, and erect, streamlining project timelines.
Why Opt for Castellation?
- Improved Structural Efficiency
Castellated beams optimize material usage by distributing loads more effectively. This efficiency results in lower steel consumption, helping cut costs without undermining safety or longevity. - Increased Versatility
Reduced beam weight and strategic cell placement open new possibilities in building design, allowing for broader spans and more creative architectural elements. - Built-In Mechanical, Electrical & Plumbing (MEP) Coordination
The cells in castellated beams can act as pathways for electrical conduit, plumbing, and HVAC systems. This integration eliminates the need for additional fittings, trimming both costs and installation time. - Eco-Friendly Profile
By using less steel and reducing transportation loads, castellation supports sustainable building practices—an advantage for projects aiming to meet green building standards.
Our Castellation Approach
- Precision Planning
Every castellation project begins with meticulous design. We collaborate closely with clients and structural engineers to determine the optimal cell geometry, size, and placement. This planning phase ensures that performance targets—such as load capacity and stiffness—are met.
2. High-Accuracy Cutting
We employ state-of-the-art CNC plasma or laser cutting machines to form exact opening patterns. These machines guarantee uniform edges, reduce waste, and help expedite the fabrication schedule.
3. Controlled Welding
After the beam has been split and separated, our skilled welders rejoin the segments to align the cells properly. We adhere to strict welding procedures and quality controls, ensuring each beam meets or exceeds industry standards.
4. Rigorous Quality Checks
Our certified quality inspectors perform continuous assessments—from verifying weld penetration to confirming dimensional accuracy—minimizing the risk of defects or structural inconsistencies.
Key Benefits of Castellation
- Reduced Construction Costs: Lower steel usage and lighter beams translate into direct savings on materials, handling, and logistics.
- Greater Design Flexibility: Castellation opens creative avenues in structural layouts, accommodating larger spans and unique shapes.
- Faster Installations: Pre-engineered openings facilitate streamlined mechanical, electrical, and plumbing works.
- Longevity and Reliability: Precisely engineered beams stand up to demanding conditions, delivering dependable performance over the long haul.
Industry Applications of Castellation
- Warehouses and Distribution Centers: Castellated beams allow for open, column-free interiors that maximize storage capacity.
- Commercial Buildings: Leveraging lighter, high-strength beams means more versatile floor plans and easier integration of building services.
- Industrial Facilities: The inherent ducting paths help manage complex utilities, simplifying upkeep and expansions.
- Infrastructure Projects: Whether in bridges or elevated roadways, castellated beams offer strength, durability, and material savings.
