Decking Sheets
Overview
Decking Sheets are structural steel sheets designed to provide a strong and stable platform for floor slabs in multi-story buildings, bridges, and industrial structures. Acting as a permanent shuttering and working composite with concrete, decking sheets significantly enhance structural strength while reducing construction time and cost.
At BSSM Infra, we supply high-quality galvanized steel decking sheets that combine strength, durability, and efficiency. Our decking sheets are widely used in commercial buildings, factories, metro stations, and high-rise projects, offering superior load-bearing capacity and long-term performance.
What are Decking Sheets?
Decking Sheets are profiled steel sheets that serve dual purposes — they act as a formwork during concrete casting and as a reinforcement after the concrete has set. When concrete is poured over the profiled surface, it bonds firmly with the steel ribs, forming a composite floor slab that provides excellent structural rigidity and strength.
This system eliminates the need for temporary supports or formwork, thereby saving construction time, material, and labour costs — making it a preferred choice in modern construction.

Reflective decking sheets are roofing or cladding sheets made with a reflective surface, designed to reduce heat absorption and improve energy efficiency by reflecting sunlight.
They are typically made from high-quality metals like galvanized steel, aluminum, or color-coated steel, with a reflective coating that enhances thermal performance.
Reduces heat inside buildings, making interiors cooler.
Saves energy by lowering air conditioning costs.
Durable and corrosion-resistant.
Lightweight and easy to install.
Enhances natural lighting by reflecting sunlight.
Industrial warehouses
Commercial buildings
Residential roofing
Cold storage facilities
Outdoor shelters and sheds
Yes, they are highly durable, resistant to corrosion, weathering, and UV radiation, making them suitable for long-term use in all climates.
The reflective coating minimizes solar heat absorption and reflects a significant portion of sunlight, keeping the interior cooler.
Yes, these sheets are lightweight and designed for quick and easy installation with standard roofing accessories and fasteners.
Yes, they are available in various thicknesses, colors, profiles, and sizes to suit different construction requirements.
Minimal maintenance is required. Regular cleaning of dust or debris is recommended to maintain reflectivity and performance.
Yes, while the initial investment may be slightly higher than standard sheets, the energy savings and long-term durability make them highly cost-effective.
