Purlin & Decking
Purlin and decking solutions are essential components in modern construction, providing structural strength and stability to roofing and flooring systems. Purlins act as horizontal beams that support roof loads, while decking sheets offer a solid, durable platform for floors and roofs. Our products are designed for superior performance, ensuring long service life and reliable support in various building applications.
We offer Purlins made from high-quality steel for exceptional load-bearing capacity and resistance to environmental factors, and Deck Sheets that are engineered for easy installation, enhanced strength, and efficient load distribution. Both products are suitable for industrial, commercial, and residential projects, helping create safe, durable, and cost-effective building structures.
A. Purlin
Purlins are horizontal structural members used in pre-engineered buildings (PEBs), industrial sheds, warehouses, and metal roofing systems. They are placed across the roof or walls to provide support to sheeting and transfer loads to the primary structural frame. Typically formed from cold-rolled galvanized or galvalume steel, purlins are light in weight yet strong in performance, offering an economical and efficient solution for long-span structures.
Purlins are available in two primary shapes: C-Section and Z-Section, each suited for specific structural arrangements and load conditions.

B. Deck Sheet
Tata Decking Sheets are high-performance structural steel sheets designed for use as a permanent formwork in reinforced concrete slabs. Made from high-tensile galvanized steel, these decking sheets serve as a dual-purpose solution — acting as a working platform during construction and a reinforcement layer after concrete curing. They are part of Tata’s advanced roofing and flooring solutions and are widely used in multi-storey buildings, warehouses, commercial complexes, and infrastructure projects.
