BS 7611:1992 Facts and Figures
British Standards
Payloads In Excess Of 1,000Kg
All BS7611 designs are certified to a nominal 1,000Kg. While BS7611 does not allow the box to be marked to this load capacity, under BS7611 a total crop weight of 1150Kg is permitted. Please call us to discuss in more detail if this applies to you.
There are many new proposed revisions to BS 7611:1992. If you have any questions regarding design changes please call us to discuss.

Nail plate or Timber Diagonals
Both nail plates and timber diagonal braced boxes comply with BS7611. We have invested in machinery at both manufacturing site to fit nail plates so this has become our standard offering. We believe that using nail plates rather than diagonal battens gives the same performance more cost effectively. However we are still able to offer diagonal battens if that is your preference.
