The Gypframe code

You will see that most Gypframe products are given a reference (or Code) number consisting letters and digits - this allows you to check the type of product it is ('C' Stud, Standard Channel, Flanged Channel, etc.) and the gauge of metal used in manufacturing the component.

Understanding the codes for metal studs and channels

The first 2 or 3 digits refer to the component width, the letter/s refer to the component type, and the last two numbers indicate the metal thickness in mm, e.g. Gypframe 92 S 10 refers to 92mm wide 'C' Stud, with a metal thickness of 1.0mm.

Use British Gypsum Wafer Head Drywall Screws for fixing Gypframe metal to Gypframe metal. Their thin head minimises the risk of subsequent bulging of the lining board over fixings.

Use British Gypsum Wafer Head Jack-Point Screws for fixing Gypframe metal to Gypframe metal where one or both of the sections is between 0.8mm and 2mm thick. Always fix 'thin' to 'thick' so that the thin metal is trapped between the 'thick' metal and the screw head.

Select British Gypsum screws to give a nominal 10mm penetration into the metal.
