A unique suspend concrete flooring system
Jindal Steel and Power Limited (JSPL) is one of India's major steel producers with a significant presence in sectors like Steel, Mining, Power Generation, Petroleum, Infrastructure, Cement and Info-solution.
From the widest flat product to a whole range of long products, JSPL today sports a product portfolio that caters to varied needs in the steel market. The company also has the distinction of producing the world's longest 121 meter rails and introducing parallel flange beams in India.
Recently JSPL has arised with revolutionary and innovative technique to eliminate the outdated conventional flooring system with suspended concrete flooring system known as ‘Jindal Speedfloor’. The manufacturing facility for Jindal Speedfloor is located 30kms away from the heart of Raigarh City, Chattisgarh at O.P. Jindal Knowledge Park, Punjipatra.
With an annual turnover US $ 3.5 billion, JPSL has committed investments exceeding US $ 30 billion in the future and has several business initiatives running simultaneously across India, South-East Asia, Africa, South America,Australia and Georgia.
Strengthening IndiaGoing Global
l Steel used for making JOIST is of Grade 350 which has a minimum yield stress of 350MPa and a minimum tensile stress of 380Mpa as well a minimum coating of Z275 is maintained.
l Generally Speedfloor uses a 75mm or 90mm topping in comparison to the other conventional RCC flooring systems.
The joist weights per linear metre are as follows:
a. 200mm deep = 9.41 kg/mb. 250mm deep = 10.59 kg/mc. 300mm deep = 11.76 kg/md. 350mm deep = 12.94 kg/me. 400mm deep = 14.12 kg/m
SPEEDFLOOR, the unique suspended concrete flooring system, is an innovation in the building industry. So quick and easy to install,
SPEEDFLOOR is a lightweight, cost-effective system that's perfect for multi-storey buildings and carparks. Whether it's one storey or fifteen,
the recipe is very simple. take sufficient quantity of SPEEDFLOOR, add structural steel or concrete supports, mix concrete and pourlAt the
heart of the system is a specially rollformed, galvanised steel joist that offers all the benefits of an open-webbed truss system at a more
enough to be man- handled into place, reducing cranaage costs. Services are easily accommodated through the joists which are delivered to
the site ready to install. SPEEDFLOOR The perfectly simple, simply perfect solution to multi-storey construction.
l No propping is required.l The joists are lightweight, requiring less craneage than other concrete flooring systems.l Services can be passed through the holes pre-punched in the joistl The bottom of the joist can support a suspended fire rated ceiling directly fixed to the joist.l The lockbars and plywood sheets are reusable.

SUPPORT
1The individually marked, lightweight rollformed steel joists are easily lifted into place on the support medium. 3
Lockbars are placed approximately 300mm apart to give the plywood good support.
2Lockbars, which will support the plywood shuttering, are slid into the slots punched in the top section of the joist and by engaging the notches at both ends of the lock bar, the exact spacing of the joist is secure.
4The plywood is introduced from the top and is held in position by the cam action of the lockbars. A working platform from which the rest of the plywood can be laid is quickly progressed down the building
6The finished floor after the lock bars and plywood are removed reveals the concrete soffit and exposed joist where services can be passed through pre-punched holes. The bottom of the joist can support a suspended fire rated ceiling directly fixed to the joist.
5The mesh is laid out and tied into place. No stools are required as it is held off the deck by the top section of the joist, which becomes embedded in the concrete and will gain composite action once the concrete is cured.
Easy to install
Our name says it all.
l The concrete slab topping has a compressive strength of 32MPa after 28 days.
l Speed floor system can meet fire rating requirement set out in building codes through various means such as fire resistant painting of joists, fire rated ceiling.
