StrongFix – improved support from Norbord

StrongFix HRSometimes, even the simple task of hanging a picture or a mirror on an interior partition wall has been fraught with difficulty due to the common challenge of a weak plasterboard substrate.

That is no longer a problem thanks to Norbord’s SterlingOSB Zero StrongFix.

Specifically designed for dry lining applications, SterlingOSB Zero StrongFix is a precision engineered oriented strand board (OSB) with a special groove machined into the edge for metal C-studs at 600mm centres.

SterlingOSB Zero is made from several layers of softwood strands, carefully layered and bonded under heat and pressure with a strong zero-formaldehyde resin to create a strong board.

Superior to plywood, which contains knotholes, splits and cracks, OSB has a consistent density meaning you can attach fixings, hang pictures or fit items of furniture securely anywhere on the panel.

In accordance with the requirements of BS5234 Part 2, SterlingOSB Zero StrongFix achieves excellent pull-out ratings and is capable of supporting heavy weights of up to 400kg with standard wood screws.

SterlingOSB Zero StrongFix panels are easily fixed between C-studs by simply fixing an L-section steel strip along the non-grooved edge with 25mm self-tapping drywall screws and then angling the board so that the recessed groove engages the lip of the opposite C-stud.

With the panel in place, it is secured with self-tapping screws driven through one C-stud into the L-shaped strip and through the opposite stud, into the edge of the board. The recessed groove allows quick installation and ensures a seamless finish, ready for hanging plasterboard without adding any extra thickness to the stud wall.

SterlingOSB Zero StrongFix is supplied in 18mm-thick, 2,400mm x 597mm panels with 50 sheets per pack. Non-standard sizes are available on request.
