Cellular Beam
Steel Structure Services
A Cellular Beam is an engineered structural steel beam with circular openings along its web, manufactured by cutting a standard hot-rolled H-beam and re-welding the halves together to increase its structural depth and bending capacity.
Key Components
Top Flange: The upper horizontal steel plate that resists compression forces.
Bottom Flange: The lower horizontal steel plate that resists tension forces.
Web: The vertical middle section of the beam that connects both flanges, containing the cut-out shapes.
Openings / Cells: Circular holes punched or cut along the web, designed to accommodate building services.
Key Benefits & Advantages
MEP Service Integration: Utility pipes, electrical conduits, and air-conditioning ducts can pass directly through the web openings, reducing the required floor-to-ceiling height.
High Strength-to-Weight Ratio: Offers excellent bending stiffness while reducing the overall weight of the steel structure.
Cost Efficiency: Decreases overall material usage and lowers loads on building foundations.
Long Clear Spans: Perfect for wide-open interior spaces that require fewer interior columns, as seen in modern offices and showrooms.
A Pre-Engineered Building (PEB) is an advanced steel structure system where all primary and secondary components are custom-designed, engineered, and fabricated in a factory before being transported and rapidly assembled on-site.
Key Components
Primary Framing: The main structural skeleton, consisting of heavy steel columns and tapered rafters that form rigid frames to support vertical and lateral loads.
Secondary Framing: Cold-formed steel members—such as purlins (for roofs), girts (for walls), and eave struts—that hold the cladding and transfer loads to the primary frame.
Roof and Wall Cladding: Exterior coverings typically made of profiled steel sheets, metal roofing, or insulated sandwich panels.
Bracing Systems: Cross-bracing, rod bracing, and portal frames that provide longitudinal stability against wind and seismic forces.
Accessories: Add-ons like skylights, wall lights, roof ventilators, gutters, downspouts, and crane systems.
Key Benefits & Advantages
Fast Construction: Pre-fabricated parts mean assembly is mostly bolted, reducing construction time by 30% to 50% compared to conventional buildings.
Cost-Effective: Optimized structural design (using tapered sections where stress is highest) minimizes steel waste and lowers labor costs.
Large Clear Spans: Enables wide, column-free interior spaces of up to 100 meters wide, ideal for warehouses, factories, and aircraft hangars.
High Quality Control: Components are manufactured in controlled factory environments under strict engineering tolerances.
Easy Expansion: Buildings can be easily extended or modified in the future by adding more bays or frames.
Low Maintenance: High-quality protective coatings and durable metal panels ensure strong resistance to weather, rust, and wear.
