Semi-frameless Glass Balustrade is manufactured from 10mm toughened “Grade A Safety” glass. The Aluminium double sided glazing posts are 50mm round or square extruded aluminium and can be core drilled into concrete, flanged or in-ground depending on your requirements. Stainless Steel posts are 50mm round or square in number 4 brush finish. We also do polished Stainless Steel. As there is no stainless steel double sided glazing post available you will require 4 Stainless Steel clamps per panel of glass. Balcony balustrade must have a handrail at a minimum of height of 1m.
