Normally clients will choose tempered and laminated glass for glass canopy, because it is strong and breakage resistance. But it is professional to choose heat strengthened glass for glass canopy.
Heat strengthened glass process is similar to tempered safety glass but with lower surface compression, resulting from a slower speed cooling after heated. The heat strengthened is about 2 times stronger than annealed glass, while tempered glass is 5 times stronger. However heat strengthened glass is more smooth on the surface, which is an important benefit to produce high quality laminated glass. Another benefit is that, heat strengthened glass is not spontaneous breakage.
So heat strengthened glass is usually used for laminated glass. Specially good for canopy glass. In the morning or afternoon, glass may harf exploded in sunlight, rest in shaow. The heat absorbing might be unequal in different part of the canopy glass. This may cause the whole glass spontaneous breakage. But heat strengthened glass avoid the risk of this problem.
