Like Allan says 2.0KN/M2 is standard
2.5KN/M2 is heavy duty

Proper SGB cuplok is rated for 3kn/m2 on a 2.5mX2.5m bay.So its heavy duty on light duty sizes compared to t&f.

 

[neil81]

QFS had 2.5kn as general purpose on their badly designed In house scaff tags. I pointed this out but it fell on deaf ears :wacko:
