Structural steel hollow sections
Such as circular, rectangular, and square tubes are distinguished by their closed, hollow cross-sections, offering a range of functional advantages across various applications. Their high strength-to-weight ratio makes them structurally efficient, ideal for constructing lightweight yet robust frameworks in roofing, bridges, and trusses. These sections also exhibit excellent torsional resistance, enabling superior performance under twisting forces, which is essential in space frames, cantilevered structures, and machinery. Aesthetically, their smooth, continuous profiles lend themselves to modern architectural designs, commonly seen in exposed façades, staircases, and sculptural elements. Additionally, the hollow cores can be utilized for integrating electrical, plumbing, or HVAC systems, contributing to building efficiency. Their uniformity and compatibility with prefabricated systems further enhance their value in modular construction and scaffolding, allowing for quick and efficient assembly.

Structural steel built ups
Custom-engineered structural elements created by combining standard steel components—such as plates, I-beams, and channels—through welding or bolting. These sections are designed to handle extreme loads, making them ideal for large-span structures like crane girders, industrial warehouses, and bridge girders. Their versatility allows for tailored geometries and load adaptations, accommodating irregular column shapes or enhancing seismic resistance. Built-up sections are also well-suited for composite applications, integrating with concrete or other materials to form hybrid systems used in high-rise cores and composite beams. They offer cost-effective scalability by optimizing material use for large-scale infrastructure projects, including transmission towers, wind turbine bases, and shipbuilding. Additionally, their inherent ductility and resilience provide enhanced energy absorption, which is crucial for structures in dynamic or earthquake-prone environments.
