rojects. The in-fills keep the weight of the floor to a minimum and are then covered with in-situ concrete to form the ribs and the floor slab. Concrete Panels Flooring. Pre-stressed concrete bridge beams have become firmly established as the preferred option for a wide range of bridge spans and types. We can supply precast and prestressed passage slabs depending on the loadings required. Prestressed concrete on the other hand, is a form of concrete which is commonly used for our prestressed concrete panels for the likes of agricultural buildings. Prestressed flooring is the most effective type of flooring where large spans and shallow depths are desirable. Prestressed concrete wall panels, are a versatile product which can be used to store and retain a wide variety of materials. 15′ and 20′ concrete panels in stock for immediate delivery. This combination makes a very strong structural material that is used in the building of roof slabs, bridge girders and railroad ties. We offer design, manufacturing and transport, installation, grouting, openings, coring and walling. Passage Slabs. Prestressed Extruded Concrete Floor Units. This ensures a uniform high quality product. Spancrete hollowcore precast concrete planks & slabs are fire resistant, reduce weight and costs. Learn more and see projects with hollowcore slabs. The process involves extruding wet concrete along with the prestressed steel wire rope from a moving mold. Developments in structural design, material strength and manufacturing have enabled pre-stressed concrete bridge beams to be used in significantly greater spans. Concrete Panels Flooring. The panel dimensions can be tailored to suit project requirements, making them the perfect solution for a wide range of applications. Concrete cast to the core. Prestressed concrete, Concrete reinforced by either pretensioning or posttensioning, allowing it to carry a greater load or span a greater distance than ordinary reinforced concrete. CE marked, quality products that are made in Britain. An additional comprehensive study of global Prestressed Concrete Wire and Strand market distributors, sales channel, traders, dealers, appendix, and supply information is provided. Hollowcore is extremely durable, retaining its structural capacity for a lifespan of 100 years or more. 1000 metres of concrete panels manufactured every day . Web Design by LW Design. Sometimes conventional reinforcement isn't enough. Used in many residential and industrial projects, prestressed slabs now form an integral part in the provision of our agricultural solutions. To be prestressed, the concrete is ‘prestressed’ by being placed under compression prior to supporting any loads beyond its dead weight. Elematic SA (Pty) Ltd . Prestressed Floors Basic Design Parameters No propping is required. Prestressed concrete was invented and patented in 1886 by Henry Jackson, a San Francisco engineer. Global Prestressed Concrete Wire and Strand manufacturing method has been demonstrated with … The prestressed concrete floor slabs are delivered on-site already ‘made to measure’ and ready for immediate use. CONTACT US . In addition to this range, we also manufacture a 100mm deep precast concrete floor slab. Compression is a force that squeezes or crushes, and tension is a force that pulls something apart. These are either a full depth unit with a finished concrete surface, or a composite unit, with a roughened surface to act compositely with an in-situ structural concrete topping. Market leaders in prestressed concrete panels and flooring since 2005. Prestressed Concrete Panels Favoured by the agricultural industry for many years, prestressed concrete panels are one of the most versatile precast systems on the market. At Flood Precast, we allow site work to continue, even when the weather is not at its most helpful for concrete. Prestressed concrete is a system into which internal stresses are deliberately induced without any form of external loads to improve its performance. Of Civil Engineering, Universiti Teknologi Malaysia. These properties are enhanced for structural elements manufactured as prestressed concrete. The most popular prestressed concrete elements are roof slabs, piles, poles, bridge girders, wall panels, and railroad ties. These units are a prestressed concrete slab normally 1200mm wide (part widths are also available if required) and a current depth range of 150mm to 450mm. As well as the prestressed wire reinforcement the half slabs have steel mesh embedded in the lower part to further increase the element strength. Design process includes proper assumption of structural element sizes and then check […] Ideal for applications where enhanced structural performance and lateral load distribution is required, such as in industrial buildings, and multi-storey buildings and car parks.
