CELLULAR BEAM

Cellular beams are steel load-bearing elements designed with circular body cavities to increase structural efficiency and reduce their own weight. They are commonly used in large span industrial and commercial buildings, allowing mechanical and electrical installations to pass through the cavities, thus reducing floor height and facilitating installation passage. 

Steel components can be manufactured painted or hot-dip galvanized for corrosion protection. 

These components are produced using steel grades compliant with international standards.​

Areas of Use:
• Industrial buildings
• Commercial buildings
• Sports halls
• Shopping malls
• Office buildings 
• Bridges and long-span structures

CASTELLATED BEAM

Castellated steel beams are structural elements obtained by shaping the steel profile web according to a specific cutting pattern. As a result of this process, hexagonal or other geometric openings are formed on the web.

This manufacturing method increases the section height, thereby enhancing the bending strength capacity. The created openings reduce material usage while also allowing the passage of installations.

Thanks to their high load-bearing capacity and optimized weight structure, they enable economical, efficient, and high performance structures with reduced material usage for wide spans. They are widely used in industrial, commercial, and architectural buildings.

They offer long lasting use with painted and galvanized coating options.

Areas of Use:
• Industrial buildings
• Commercial buildings
• Sports halls
• Shopping malls
• Office buildings
• Bridges and long-span structures

TYPES OF CELLULAR & CASTELLATED BEAMS

• Hexagonal Castellated Beams
These beams have hexagonal openings created by cutting and rejoining in the middle body section of the steel profile. They provide a balance between strength, reduced self-weight, and material efficiency. They are used in residential, commercial, and industrial structures for medium and long spans.

• Circular (Cellular) Beams
These beams are produced with circular openings in the middle body section. They improve structural efficiency and allow mechanical and electrical services to pass through these openings. They are preferred in large-span projects that require both functionality and a clean architectural appearance.

• Custom Designed Cellular & Castellated Beams
Depending on project requirements, opening shape, spacing, and dimensions can be specially designed. They provide flexibility in load-bearing capacity, span optimization, and service integration while maintaining structural performance.

Cellular & Castellated Steel Solutions ▲

Cellular and castellated steel beams are structural elements whose load-bearing capacity is increased and span performance is optimized by rearranging the cross-sectional geometry.

Cellular beams are designed to reduce section weight while maintaining the moment of inertia through circular openings opened at regular intervals on the web. This structure provides a controlled balance between bending rigidity and material usage ratio.

Castellated beams, on the other hand, increase the effective section height by creating hexagonal, polygonal or trapezoidal openings on the web. This method is especially preferred in long-span systems where bending strength is critical.

Both systems are widely used in industrial structures, commercial buildings, warehouse solutions and roof systems. In steel construction design and manufacturing processes, they are integrated into engineering calculations according to section optimization and structural performance criteria.
