Concrete reinforcement design and
manufacturing technology has just rolled forward...
Imagine a software design system which takes your intended slab
or floor shape, applies all stress calculations, presents a
contour loading map on screen, determines the precise reinforcement
requirements - showing the right size bars, at the right length,
exactly where they are needed, in both directions. Now imagine
a machine which produces the finished steel mat, with every
bar correctly positioned to meet your design criteria, then
rolls it up so it can be laid just like a carpet on the site.

This new technology from HY-TEN gives
designers and consulting engineers a more efficient way of
preparing reinforcement drawings for concrete construction
than has ever been possible before.
And it is not only layout planning which is simplified by the
system. Because the final steel layout is also manufactured
directly from your downloaded data, the reinforcement is supplied
completely bespoke, as a made-to-measure product meeting the
loading characteristics of your building design. As the appropriate
steel is positioned only where it is needed, less material is
used overall - and you reduce the costs.
The contractor also saves money by the ease with which the reinforcement
can be laid. Each layer of steel is delivered as a roll, one
for each direction, with spot welded steel straps locating the
bars in their correct pre-spaced positions. Unrolling the carpets
of reinforcement onto the formwork is thus a quick and straightforward
task which improves construction times significantly. Even when
precast concrete floor elements are being used, a rolled carpet
can be used for the upper layer.

In the past...
Finding a more economical way for the design and placement of
concrete slab reinforcement than the traditional methods is
long overdue in the construction industry.
For too long, the old methods have led to substantial quantities
of steel being placed in areas where it is unnecessary in order
to satisfy highest loading conditions in particular sections
of a slab. Wastage caused by cutting and overlapping sheets
of fabric has added further to the costs.

The new way...
Now, based on the loading contour map from given design criteria,
the BAMTEC® system from HY-TEN is able to calculate the
required reinforcement in both directions and for the upper
and lower layers, separately. By interactively splitting up
a slab area into as few as possible carpet sections, the system
then automatically identifies the diameter, position, length
and spacing of every single bar in the carpet.
This data forms the instructions by which the reinforcement
fabrication equipment produces the rolls of material for transportation
to the site, where it is placed and rolled out without the need
for support stanchions and cross beams required for standard
mesh panels. Carpet rolls of up to 15m width and in excess of
20m length can be produced.
Fixing plans are generated for each carpet to define the precise
placement, fitting and overall layout and bar position of the
reinforcement. Site engineers are thereby able to ascertain
all relevant information in advance of fixing the steel in position.

Costs reduced...
New technology from HY-TEN is now able to give you savings in
virtually every aspect of your building and civil engineering
projects containing slab-type components.
From the point at which the process starts in the Finite Element
calculation and integration with the CAD system to produce an
orthogonal reinforcement network diagram, savings are being
made. Automatic production of the reinforcement carpet detailed
by the system, together with all vital dimensions and installation
instructions, adds to the savings.
Downloading data to HY-TEN's automated fabrication equipment
from the design office, either by a direct on-line modem link
or by disk, further reduces costs and helps to avoid errors.
You also have the assurance that the endproduct will conform
absolutely with your finalised design. What is more, the fabrication
cannot be delayed by adverse weather conditions and quality
in production is ensured by the computer-controlled machinery.
Then, there are the exceptional savings arising from the reduction
in steel used by the sophisticated design system. Wastage and
unnecessary steel is eliminated completely, leading to potential
material cost savings of up to 50%.
More savings can be made at the installation stage because,
in most cases, just two workers will be suffizient to position
and roll out the reinforcement carpet. lt is possible to achieve
installation time savings of up to 90% when compared with traditional
fixing methods of bar and mesh.
Moreover, the inherent dimensional accuracy of the supplied
product, which is also maintained during the concrete pouring
stage due to the spot welded strapping technique employed, means
lower inspection and quality control costs at the site.

about...
HY-TEN has been at the forefront of innovative building technology
since it wäs established in 1959. With headquarters at RICHMOND
and branches throughout the UK at BOOTLE, NEWARK, POOLE, ROCHESTER,
STAINES and WOLVERHAMPTON, we have developed considerable expertise
in the supply of reinforcing bar, mesh, helicals, accessories,
sheet piles, steel sections, building chemicals, fencing & industrial
mesh, gabions and land reinforcement.
The BAMTEC system from HY-TEN is the result of extensive development
by HÄUSSLER, NEMETSCHEK and HUNDEGGER in Germany, where the
system has been proven to make significant cost and time savings
in the construction of concrete slabs.
