Yes. Most of the TimberTech railing profiles can be installed with TimberTech round or square aluminum balusters using a Custom Rail Pack. We also offer Impression Rail Express® and Impression Rail®, which are fully aluminum railing systems. The TimberTech railing system has only been tested with our aluminum balusters; therefore, we do not warranty the use of other manufacturer’s components with TimberTech Rail. For more information about installation, please reference our Rail Installation Guides.
