Metal U Track is a galvanised metal section used to create wall linings. It is manufactured by taking a roll of galvanised steel and shaping it into a "U" shape using a cold rolling machine. The tracks are then cut into 3m lengths.
Metal U Track is used as the horizontal framework of stud partitions, used in conjunction with vertical studs (C Studs). It is part of the complete drywall range manufactured by plasterboard makers such as Knauf Drywall and Siniat, and should be installed with a performance plasterboard such as Soundshield Plus, and a sound insulation product such as Rockwool RWA45 Slab. This provides an acoustic stud wall that prevents noise passage between rooms.
Metal U Track comes in a range of sections to suit all partition systems. This lightweight steel section is normally denoted by its width, depth and length. For instance, 72mm Metal Standard Track 3000mm is a 72mm wide Metal Track that comes in a 3m length. The "Standard" part refers to the depth of the track, which in this case is 25mm. These are also sometimes referred to as the "legs". A track with 50mm legs is referred to as Deep Track. Use different depths dependant on the partition height. There are five standard widths of track; 52mm, 62mm, 72mm, 94mm and 148mm, with 52mm and 72mm being the most popular. All track is sold in packs of 10.
One of the key features of U Track is that it is lightweight and therefore easy to handle and install. U Track must be installed on both the floor and ceiling where you are building the wall linings. It is common to use standard track on the ceiling and deep track on the floor - as such, these are sometimes referred to as top and bottom track.
For installation, make sure the floor track and ceiling tracks are aligned with each other. You should mark the areas first with chalk to ensure that they are positioned correctly. Then, fix the steel tracks to the concrete using hex head concrete screws. The screw should go through the metal and into the concrete - use a hammer drill for this. Lengths of adjoining track can by installed together by overlapping the end of each length with the beginning of the next.
Once the track is in place, you can install Metal C Stud by friction fit and then screws. Then you can fix your plasterboard and fill the space with acoustic insulation. For accessories used in this process, see our Metal Accessories section.
