Rib Lath Sheet


Rib Lath is stiffened by longitudinal ribs, for use on ceilings and partitions. For internal and external plaster key applications and anti-crack control. In external applications and where there is regular exposure to moisture, heavy condensation, persistent damp or concern that drying out times may be extended, stainless steel should be used.

• RLG in Galvanised Steel EN 10346 DX51D Z275 for internal use.
• RLS in Stainless Steel 1.4016 (Grade 430) for external use.
• Sheet size: 2500mm x 600mm
• Rib Depth: 8mm
• Manufactured in accordance with BS EN 13658-2:2005 for external use and BS EN 13658-1:2005 for internal use.

Rib Lath is fixed so that the tip of the rib is placed against the supporting background. The rib of the sheet should run at right angles to any supports. Ensure that the sheets are overlapped by a minimum of 50mm end to end and by 25mm widthways and that the ribs are nestled together.


Rib Lath is fixed at each rib to timber supports using plasterer’s nails, screws or
staples. Ensure that compatible corrosion resistant fixings are used, i.e. do not use galvanised fixings for stainless steel.


Rib Lath is fixed at each rib to metal support using galvanised or stainless steel tying wire. When joining Rib Lath sheets, overlap the edge ribs and tie the edges with tying wire at 150mm centres.


Rib Lath can be fixed to a solid background using a suitable fixing which holds the ribs firmly against the background. Where sheets are installed vertically, fixings should be positioned through all ribs at 600mm centres to ensure adequate stability.

Always ensure that compatible corrosion resistant fixings are used, i.e. do not use
galvanised fixings with stainless steel products or vice versa.

Gloves should be worn as edges will be sharp
