| In modern high rise building, fully unitised systems are frequently being used in construction to save time and cost. Most of the unitised system comprises of structural aluminium alloy of grade 6063 T5 or T6, with spandrel panel (shadow box) and vision glass.
| The paper shows that the residual stress at the surface of tempered glass panels may vary both locally and globally, i.e., stresses near the edges and corners of the panels may be considerably different from the stresses in the middle part of the panels.
| The canopies are a composite construction between both steel and glass, leaving no element without stress or structural function.
| Glass industry standards in different countries require 24/7 quality control with the same specifications and fully automated analyses and following statistics.
| Process control is a key factor for speed and efficiency of IS machines. To run a machine at high performance levels it is essential to achieve and maintain stable production conditions.
| The current manufacturing of tempered glass is a complex as well as time- and cost-intensive process. Not only long processing times, but also high energy costs have a significant impact.
| In recent years there have been a number of sensational reports in the media about “glass cancer” and “spontaneous glass fracture”, with stories relating to “glass raining down from highrise buildings”.
