The Angle Wall System

Since 1948, many hundreds of thousands of buildings have been erected world wide using precast concrete "Flat Panel" systems.

In the late 1960's the aws System was developed utilising aws shaped load bearing walls instead of flat panels, thereby dispensing with propping during erection and vastly reducing panel joints. The benefits of this high technology system have been appreciated the world over with the successful, trouble-free completion of thousands of dwellings, apartments, hotels, campuses and military cantonments. The immense strength and ruggedness of the system means that buildings can be constructed well in excess of thirty storeys high and in the most hostile geological environments. The AWS system meets with the Zone 3 requirements of the Californian code for seismic design and the Florida Hurricane Code.

The flexibility of the AWS System

Because house designs based on the AWS System can be considerably varied, large housing schemes or estates need not look dull or uniform. The AWS system permits varied internal planning and because the panels are cast in machined steel moulds, the accuracy and superb finish of the panels also means that finishes can be apllied direct. Equally the panels can be clad or treated externally to provide a variety of aesthetic solutions.

Economy of the AWS System

The world wide usage of the AWS system demonstrates it's economic benefits in terms of speed and simplicity over comparable traditional buildings. The AWS system does not require a highly skilled workforce for its manufacture or erection. The panels are completely self supporting and therefore site installation is simply achieved with a small number of operatives and a mobile crane keeping the erection procedure simple, speedy and economical.

The AWS system was principally developed to deal with mass housing needs in developing countries. The system is sufficiently flexible to be used for other types of construction including hospitals, clinics, schools, municipal buildings and shops and is one of the few systems in the world capable of producing consistently up to 440m2 of erected building in each 24 hour period with a quality control which renders internal finishing trades a thing of the past.

Since its inception in 1969, the system has been used in 12 countries having various geological and climatic conditions ranging from the eathquake zones of Mexico (where it was granted Zone 3 status within the Californian code of seismic design) to the deserts of Saudi Arabia and the tropical rainforests of West Africa.

The AWS system has always achieved considerable economic savings wherever it has been used. These savings have been achieved by efficiency and the fact that a much lower number of skilled and semi-skilled personnel are required compared with traditional construction methods.

The system has also been used in Russia where a specially designed sandwich panel gives adequate insulation from +40F to -30F.

Construction Method

The AWS system comprises a number of pairs of specialised vertical steel moulds, producing both AWS shaped and flat concrete panels which can either be utilised for casting on site, thus reducing transportation, or alternatively emplaced within a factory complex convenient to the site so that the finished panels can be transported on conventional low load trailers.

The moulds are of robust steel plate and sections. They are adjustable to cast units of up to 3.30m high with arm lengths 3.00m for the shorter arm and 6.60m for the longer arm. The moulds can open and close hydraulically whilst an overhead or mobile crane is used to remove the precast elements from the mould after heat curing of 3.5 to 5 hours. This allows the mould to be used more than once per day.

AWS International provide a full transfer of technology pacakge where our own experienced engineers train locally recruited staff to the highest European standards and are only withdrawn when the client confirms his satisfaction.

Mass Housing

The AWS system is suitable for all housing contracts from medium to very large with sufficient flexiblilty to construct all forms of housing from low cost 35m2 apartments, designed for the Indian economically weak sector, to 200m2 luxury apartments in Saudi Arabia.

The first moulds were produced in 1969 and since then there has been a constant technical evolution. However, the basic engineering remains the same which is a tribute to both the practicality and ruggedness of the AWS moulds, and to the simplicity of the AWS system of building. These two important factors have demonstrated time and again the suitability of AWS for low and high rise mass housing where speed, economy and durability are essential requirements.
