12 September 2013
BS 576 Part 22 - postboxes, letterboxes & mailboxes are now available through Postbox Solutions
Postbox Solutions now offer postboxes to the very high BS standard BS 476 part 22, this is a 1 hour rating for postbox units that are to be fixed into or onto a fire rated wall.
The Safety Letterbox Company in association with the Fire Research Laboratory worked together to create a range of 1 hour fire rated (integrity only) mailboxes.
Particularly suitable when mailboxes can only be positioned within a designated fire escape route or banked in a post room which must be fire rated.
The products in this section were required to satisfy the integrity criteria given in BS476 Part 22 1987 Clause 8 for a period of 60 minutes.
In addition to the above, the mailboxes can be further enhanced by applying a finish which would conform to London Underground surface spread of flame requirement BS476 Part 6 & 7.
