USG Boral Suspended Ceiling Grid
USG grid is now known as USG Boral suspended ceiling grid due to a partnership between the two companies. This article reviews the exposed grid system from USG Boral and highlights the features that make it a great choice.
The system comes in 3.6m mainbars, 1200 T bars and 600 T bars. Wall angles are available in standard L, extra wide L, metal and aluminium shadow line profiles. Products comes boxed in cardboard boxes to prevent damage to the grid.
Main bar
Main bar is constructed from galvanized steel to prevent rusting, with the seen face sprayed white to match the majority of ceiling tiles on the market. This grid system is also available in black which I will cover in a future review. The T bar punch holes are set out at 100mm centres and have alternating holes going from left to right to double punch holes. Whilst this doesn’t sound like a big deal, it makes construction easier. This is due to most ceiling layouts being either 1200mm x 600mm or 600mm x 600mm. This is turn reduces effort when counting spacing clipping in 1200 and 600 bars. The punch holes along the top of the main bar spine are great for fish hook style hanging, as using lower holes can cause problems fitting thicker tiles.
Main bars connect adequately once connected, provided the bars are parallel when connection occurs. USG Main bar can be disengaged without tools too, which is a bonus.
T Bars (cross bars)
Pictured below is the QRC clip that is present on both 1200 and 600 bars. QRC stands for quick release clip and unlike other grid systems these bars can be quickly disengaged without tools. This process also leaves the T bar undamaged and able to be reused. One note worth mentioning is in recent times the material used to make the QRC clip, I believe, has been changed from spring steel to either gal or some other weaker steel. Whilst the engagement is still very strong it doesn’t have the distinctive loud click once a bar engages that it used to have. This means you have to take more care during construction to make sure all bars are engaged. Whilst other grids are the same, I miss that crisp engagement from the old model.
T bars feature a raised up lip that sits over the top of the main bar on engage. This prevents twisting and helps the bars to sit flat providing what I feel is a way cleaner look. This can be seen in the intersection picture below.
Cross Section details
Usg clips in from the left hand side of the punch mark, with the spring tap to the outside.
Once clipped together the result is a strong stable join, that sits flat
The result is cleaner looking joins as pictured below. The main bar has been pulled slightly sideways in the picture to demonstrate the effect of the lipped t bars. Whilst several grid manufacturers still use butt style joins all round, I definitely feel these look better.
In conclusion, USG Boral Suspended Ceiling Grid provides a high quality, cost effective solution for anyone looking for an exposed grid system.
