SterlingOSB Zero StrongFix - Builders’ Questions Answered
12 June 2020

SterlingOSB Zero, and SterlingOSB Zero StrongFix specifically, compare to ply?
SterlingOSB Zero can be used for all the same structural applications that plywood can be used for, and as SterlingOSB Zero is made in the UK, the finished board is very competitively priced as it doesn’t have to travel all the way from Asia or South America like plywood does. New kid on the block, SterlingOSB Zero StrongFix is an OSB panel designed to be used in dry lining applications. It is simple to fit, highly versatile and ideal for fixing cabinets, radiators, wash basins, railings and other heavy fixtures to stud walls. StrongFix, is cut to size to fit within c-stud sections, has a pre-groove already cut and has zero knots, meaning the strength of the board is maintained throughout.

What other things does an installer need to buy to go with it?
You do not need any additional items when purchasing SterlingOSB Zero StrongFix to be used for patressing.  The product uses the same fixings – l-shaped steel frame, c-stud self-tapping dry-wall screws.

Can it be used with timber stud?
SterlingOSB Zero StrongFix can only be used with c-stud sections.

Is it a finished board?
As the application requires it to be fitted and used behind plasterboard, the panel is not finished as it will not be seen.

Does it come in different widths?
StrongFix is available in 2400mm x 597mm.

Will it compare favourably to specialist plasterboards that can carry/hold additional weight plasterboard?

These types of plasterboards are not really an equivalent product as they only hold up to 15kg whilst StrongFix can hold up to 400kgs* anywhere on the panel due to the inherent strength of the board thanks to the manufacturing process.
*refer to product data sheet

Will it work using 400mm centers?
The product is tested and produced for 600 centers. There will be waste cutting the board to size for 400mm centers.
