Company Profile
About Us

Established in 1989 Trimline Improvements is a local family owned and operated business specialising in the sale and installation of concertina doors, acoustic accordion doors, operable walls and shoji doors.

We are a major supplier to Q-build and other independent building companies involved in building and maintaining schools, government buildings, units and general housing.

We cover an area stretching from north side of Brisbane up to Hervey Bay and west to Kingaroy.

We are local sales people, distributors for and installers for Unifold Holdings P/L and Shoji Screens and Doors, who both are Brisbane Manufacturers.

It is reassuring to know that the person who sells the product to you, also measures and installs the product.

We offer a service of assistance in deciding on type of door/s required to meet your specific requirements including selection of finish and colours.

Our showroom is a great way of viewing our products as we have full size doors on display, or if you prefer, we have sample size product that we can bring on site when measuring.




Our Mission…

Is and has been for the past 20 + years to diligently supply, install and service quality products at a reasonable price, that surpasses the expectations of our clients.
