Lietzke Australia Pty Ltd, a division of the AM Group, has been supplying Heavy Duty Steel Louvre Door Units around Australia for a number of years with great success. This success has now led to the market requesting the capability of these doors to stretch further, including features such as vermin proofing, longer unsupported spans and fixed panels to match door sets.
Lietzke has met these challenges with 2 new blade designs.
The basis of the Lietzke Heavy Duty Steel Louvre Door Unit is that all materials used are pre-galvanised with all mitres in the sub-frame fully welded. The louvre blade material can range from 1.2 to 2.0mm for added security and the doors are adaptable to any locking system. Door units are supplied prime painted in a zinc rich etch primer or powdercoated in any of the standard Colorbond colour range (custom colours available upon request).
The size of door units supplied has ranged from 300mm hatch openings and louvre panels through to 4.5m high by 3.6m wide double door sets.
Most commonly each louvre door is supplied factory hung in a Lietzke BW series pressed metal door frame with matching colour.
