Lietzke Heavy Duty Louvre Doors


The Lietzke Heavy Duty Louvre Door, is manufactured to provide ventilation in harsh conditions or abusive environments. The door is manufactured from a 38mm x 38mm x 1.6mm Galvanised Square Hollow Section (SHS) steel sub frame with a mid-rail formed using 1.6mm Galvabond sheet steel. The standard ‘Chevron’ louvre blades (Optimal ‘Z’ shaped blades are available) are manufactured from 1.2mm Galvabond sheet steel. All sub frame and mid-rail joints are fully welded and dressed to a clean smooth finish. The louvre blades are fixed using sealed rivets to prevent the ingress of moisture into the sub frame. Most locking devices and hardware can be factory fitted to the door. Heavy Duty Louvre Doors are also available in Double Door configuration.
