Bolted structural glass assemblies typically rely on a constant clamping force at the bolt connections to maintain weathertightnesss and to stabilise the contact stresses. The intermediate brackets which hold the bolted panels to the structure are often referred to as "spring plates" or "spiders", which incorporate slots or holes to receive the panel bolts and allow particular degrees of freedom intended by the building designer.
Internally or externally located support structures can be as conspicuous or inconspicuous as individual preference demands.
By using a bolt fixing incorporated into the glass rather than an exterior fastener, facilitates the use of a broader variety of glass types and delivers a very pleasing aesthetic as no holes are visible in the external glass surface. The flush exterior also makes for easier maintenance.
Bolt fittings have progressively increased capacity to such an extent that, larger and heavier insulated glass units, even over 700kg, can now be accommodated, meaning high wind load applications can be satisfactorily achieved.
A extensive range of top quality, highly engineered fittings offer the perfect solution to durability and appearance, without any compromise on performance and enable any angle of slope to be achieved, including roofs and canopies.
