Perforated Beams
Perforated Beams are structural steel members designed with evenly spaced holes or slots along the web. These openings reduce weight while maintaining structural integrity, allowing for easy installation of services like electrical conduits, plumbing, and HVAC systems without additional drilling.
Perforated beams are commonly used in modern construction where lightweight structures, service integration, and efficient load distribution are required.
They provide a smart balance of strength, functionality, and efficiency. They simplify construction by integrating utility services directly into the structural system while reducing weight, making them ideal for modern industrial, commercial, and residential projects.

Available Perforated Beam Sizes & Specifications
Perforated beams are custom-fabricated from standard wide flange and I-beam sections. Web openings reduce self-weight by up to 20%, increase section depth, and allow MEP services to pass through the beam — making them the preferred choice for long-span structures. Contact our Sales Team for a custom fabrication quotation.
- Castellated beams — hexagonal web openings, depth increased ~50% over base section
- Cellular beams — circular web openings, depth increased ~40%, ideal for MEP service integration
- Web-opening beams — rectangular or custom openings in standard wide flange or I-beam sections
- Base sections available: W4 through W24 and larger wide flange and I-beam sections
- In-house fabrication — galvanizing available for coastal and typhoon-exposed structures
Common Questions
Frequently Asked Questions
How are perforated beams different from regular steel beams?
Perforated beams feature strategically created openings in the web, unlike regular steel beams that have a solid web. This design reduces weight while improving strength efficiency and allows for easier integration of services such as pipes and electrical systems.
Are perforated beams suitable for heavy structural applications?
Yes, perforated beams can be used for heavy structural applications when properly designed, offering good strength-to-weight efficiency for load-bearing and long-span structures.
What should be considered when selecting perforated beams?
When selecting perforated beams, factors such as load-bearing capacity, hole design, environmental conditions, and overall project cost should be carefully considered to ensure structural performance and long-term durability.
