Our Heritage Lead Covered Steel Patent Glazing bars are a unique product to the Standard Patent Glazing Company and encapsulate the very essence of the Patent Glazing tradition. The glazing bar design originates from Victorian enterprise and ingenuity.

The glazing bar consists of a rolled mild steel core, which when tested to BS EN 10 002-1 has a minimum tensile strength of 355 N/mm˛. The core is then sprayed with a proprietary rust inhibitor before being inserted into its cover. The covering is a seamless lead extrusion that incorporates a twin wing weathering system and glass seatings. The ends of the cover are then soldered to give a hermetic seal. Cast brass fixing plates and glass stop are screwed on to produce the finished glazing bar.

The Heritage Lead Covered glazing bar range meets all the requirements of British Standard BS5516: 2004 Code of Practice for the design and installation of vertical and sloping patent glazing.

This system is ideally suited to replacement, refurbishment and upgrading of prestigious projects, however, it should not be overlooked from today's Patent Glazing schemes, where traditional materials are appreciated.
