Introducing the Fire Rated 3 Mailbox suitable for through the wall mail processing (front entry and rear retrieval). The Fire Rated FR3 mailbox has been developed in associastion with Exova Warrington to become the first company to achieve full Fire Rating (one hour integrity only) to BS 476 Part 22.
Fire Rated mailboxes include a number of specifically developed features to meet Fire Rating standards BS476: Part 22:1987 Clause 8 which outline fire testing on building structures. The lock included in the Fire Rated 3 Mailbox uses a fire cover to limit the access for fire to the mailbox lock.
The Fire Rated 3 Mailbox flap uses an inward sprung hinge to stop the flap from falling out of the box and the mailbox aperture uses an intumescent seal which expands when exposed to a large increase in temperature; closing the gap and restricting the flow of oxygen into the mailbox.
Two Fire Rated ranges are available to use, the first option is to meet the BS 476 Part 22 which features products with specific features and benefits that result in a ‘one hour integrity’ rating.
The second option is to meet the BS 476 Part 6 & 7 which will satisfy the demands of fire protection in most cases, and provide an affordable alternative if spread of flame and non-flammable materials are acceptable.
All products achieving these standards are polyester powder coated to London Underground Engineering Standard 2-01001-002 for surface spread of flame.
How long are the Fire Rated mailboxes tested for?
Mailboxes featured in the Fire Rated BS 476 Part 22 range have been tested for up to ‘one hour integrity’ only. This standard typically tests the material that the product is made of to see if it will ‘fuel a fire’.
Are there any other Fire Rated options available?
All mailboxes can be fitted with a FireTrace™ which is a single use automatic fire extinguisher.
Can the dimension of the box / mail aperture be adapted?
No. The Fire Rated range has been tested at the specified dimensions and any adjustment in sizing will result in the mailbox not meeting the Fire Rating standards.
Do they meet the Secured by Design guidelines?
Mailboxes can be fitted with an additional security bridge feature that will comply with the Secured by Design Homes 2016 guidelines. Combining an additional security bridge with a mailbox from the Fire Rated range will comply with both Fire Rating and Secured by Design Homes 2016 guidelines.
The standard lead time we offer is around 3-4 weeks. This delivery guideline is dependent on current loading status and order requirements, and is subject to change to meet market demand.
