AL-FATTAH Stronglass is basically the premium
quality Tempered Glass, which has been thermally treated to induce
maximum strength and safety features. In order to attain maximum
quality and safety features, AI-Fattah join hands with TAM Glass
Finland, Who is world's No. 1 best Tempering Line manufacturer.
AI-Fattah brings their top of the Line latest Super model which
gives the liberty to temper any type and any size of glass.
AL-FATTAH Stronglass comes with many
outstanding features that make Stronglass the instant choice over
Strength as Compared to Ordinary
AI-Fattah Stronglass is 5-6 times stronger
then its equivalent thickness of normal or ordinary glass. Strength

Strength in Terms of psi
Stronglass induced with compressive stress of 11,000 to 20,000 psi
on surface and not less then 9700 psi on edges.
High Thermal Shock Strength:
Stronglass provides 6 times more resistant
to thermal stress in comparison to ordinary glass. It offers
increased resistance to both sudden temperature changes and
temperature differentials up to 250°C compared to normal annealed
glass, which can withstand temperature differentials up to40°C only.
When direct sunlight falls on a pane of glass then the glass surface
tends to heat up. This heating is not uniform in nature. The central
part that is exposed gets more sunlight and heats up faster while
the edges are relatively cooler. This creates temperature difference
inside the same pane of glass and when it crosses a certain limit,
there is a chance of thermal breakage. But Stronglass has
significantly higher edge strength to withstand chances of thermal
Stronglass has a high edge strength as compared to normal annealed
glass. This gives freedom to designers to use the Stronglass in
spider glazing and point fixed glazing.
AI-Fattah Stronglass is very difficult to break but even on
breakage, it will break Into small, relatively harmless fragments
there by greatly reducing the likelihood of serious injuries in
comparison with ordinary annealed glass.
This substantially reduces the likelihood of injury to people as
there are not jagged edges or sharp corners, which are normal in the
case of breakage of ordinary glass. Due to the inherent superior
feature of Stronglass like more strength, ability to withstand
sudden impacts and breaking into small pieces, it is considered as a
safety glazing and so in all advanced countries use of Stronglass is
mandatory for all the multistoried buildings. Even in Europe and
South East Asia there is a Law that one can not use ordinary glass
in building having height of 10 meters.
Theft Resistance Glass:
it is already discussed that it is very difficult to break the
Stronglass but due to any heavy impact if it breaks, it create a
loud noise. Due to this characteristic the Stronglass is also
considered as theft Resistance glass.
5-times more strength and safety character induced in Stronglass
by heat treatment process is undoubtedly a great intrinsic value
addition to glass at a slightly higher price.
Effectively, paying a little more for Stronglass is actually
paying less than ordinary glass In total, considering the
replacement cost and risk factors involved in case of ordinary
While deciding on the thickness of glass, one should keep in mind
that higher the thickness greater the strength. But as the
thickness increases the cost also increases proportionately. Any
smart user can now opt for lower thickness of Stronglass in place
of higher thickness of ordinary glass at Low cost with higher
strength and added safety factor.
The added initial cost in case of Stronglass compared to an
ordinary glass is more than compensated by the savings, as the
costs for replacement due to frequent breakage, an injury costs
are effectively reduced in this case.
it is already mentioned that Stronglass is regarded as safety glass
as it is very difficult to break and if it breaks it creates a very
loud noise. So if any robber or thief tries to enter in the house
and succeeded to break it then the loud noise can alert not only the
in house persons but also the neighbors. So this concluded that
there will be no room for grills if some one uses Stronglass.
comprehensive study of subject leads most users to opt for AI-Fattah
Stronglass In place of ordinary glass.
AL-FATTAH Stronglass is used in place of ordinary glass on account
of requiring increased strength and reduced likelihood of injury in
the event of breakage. If s use is now fast growing in the
architectural field. Like in most developed countries the concept of
using Stronglass is now becoming fast.
AL-FATTAH Toughened glass is regularly specified in:
Strain pattern being a common characteristic of all tempered
glasses, visible under certain lighting conditions at certain sharp
angles is inherent in the tempering process and is not considered a
defect. BOW, warp and process roll distortion being an inherent
characteristic of the manufacturing process may be found within the
limits set by ASTMC 1048 or DIN 1249.
Stronglass can not be cut or drilled after Tempering. Any field
alterations, Including edge grinding, sand blasting or acid etching
can cause premature failure.
