Steel Decks Dealers in Paharganj, Delhi

Multicolor steels offers a wide variety of steel deckings, used with in-situ concrete in composite floors, and has application in a wide range of buildings like mezzanine, multi-story buildings, industrial and commercial buildings etc. Composite floors are thin, lightweight, easily and quickly installed and have excellent load carrying capabilities. Typical System Layout 'Composite deck floors' or 'composite slabs' provide an effective and economical floor slab in a range of building types. They comprise profiled steel decking, in situ-concrete and mesh reinforcement. The steel decking acts as a permanent formwork to the concrete during construction and then acts compositely with the concrete to produce a strong and stiff long span floor. Temporary propping is not required in most applications. Load capacity Composite deck floors are robust and achieve excellent load carrying capacity due to the shear-bond developed between the embossed decking and the concrete slab. Load capacities upto 15kN/m² can be achieved, which can be enhanced by additional reinforcement in the slab. Light mesh reinforcement is generally used for fire resistance, and additional reinforcement required for crack control in exposed application. Fire Resistance Composite slabs have excellent fire resistance and can achieve upto 120minutes fire resistance with simple provision of mesh reinforcement. The exact period of fire resistance is dependent on: the slab depth:the deck profiles;size of reinforcement and whether normal or light weight concrete is used. Longer fire resistance period can be achieved by placing additional reinforcing bars in the ribs. Acoustic Performance The acoustic performance of composite slabs with typical floor coverings is normally adequate for office or other work applications. In applications where a higher degree of acoustic insulation is required, such as apartment buildings, hotels and hospitals, additional insulation can be provided. The incorporation of resilient layers, or a concrete screed, can enable the floor to more than meet the requirements of the Buildings Regulations. Sound reduction of 62dB(airborne) and 50dB (impact) are really achievable. Durability Steel decking is normally galvanized with a standard G275 coating. The galvanized layer is not damaged during forming and provides suitable protection and durability for applications not subject to direct weathering, or in moderate exposure conditions. We offer special corrosion resistant 'ZAM' steel (a product of Nissan Steel, Japan) which has life of more than 3-4 times then galvanized coating. Where the decking is used in exposed or damp conditions, additional measures should be provided to prevent corrosion, or the decking should be considered as permanent formwork only.
