SAS post-tensioning bars are an integral part of modern post-tensioning solutions in bridge construction, structural engineering and the upgrading of structures.
SAS bar post-tensioning systems comprise post-tensioning thread bars and smooth bars of the grades SAS 950/1050 and SAS 835/1035, as well as tested and approved anchorage elements specially developed for the systems.
SAS bar post-tensioning systems have been successfully installed for many years in transversely post-tensioned bridges and pylon heads. They are used worldwide in hall and stadium construction to tie back steel structures and rope systems and as auxiliary construction tools in bridge construction for attaching launching noses and form travellers.
To improve and ensure a functioning infrastructure that meets the needs of a growing economy and population, existing structures will have to be upgraded in the years to come. SAS post-tensioning bar tendons have already been successfully employed for strengthening existing bridges, thus providing eco-efficient, long-lasting and future-oriented solutions.
Modern wind power plants require simple, quick and cost-efficient construction systems. SAS post-tensioning bar tendons installed in the base and shaft help optimize the construction progress, thus promoting the move towards renewable energy resources. The European Technical Approval ETA-05/0122 offers designers a tested system that takes all project-specific conditions into account, e.g. post-tensioning anchorages, load transfer to concrete and corrosion protection.
Our customers have already installed our bar post-tensioning systems in various projects, e.g. Capital Gate Tower in Abu Dhabi (UAE), weir in Mont Saint Michel (F) and Johannesburg soccer stadium (South Africa).
