Installing a wall-mounted letter box or external post box is a safe and secure way to keep your mail and parcels protected from the elements, but importantly, away from the kids' hands and the dog's mouth! It can also be a smart switch over from a door-mounted letter plate as it will keep heating costs down by eliminating a source of draft throughout your home.

Including options with personalised printing, viewing windows and newspaper slots, and all with a clear emphasis on rust resistance, we'll help you keep your post safe, secure and dry for many years to come.

Stainless steel is the Don of weather resistance. This is due to its element compounds of chromium and nickel, which harden the steel and make it extremely anti-corrosive. The chromium oxidizes naturally upon contact with the environment, and then forms a protective layer of chromium oxide, creating a rust-proof shield of sorts. However, this does mean it is generally the most expensive.
Galvanised steel is steel that's been given a protective layer of zinc, generally by being dipped in a molten bath of the stuff. This layer of zinc is what gives galvanised steel its weatherproofing properties, as the zinc protects the iron in the steel from reacting with oxygen. Being cheaper than stainless steel to produce, it is the most widespread form of steel for wall-mounting letter boxes, though not quite as strong.
The final material to consider for your wall-mounted letter box is aluminium. It is known to be completely rust-proof as it has almost no iron in it, which as we know, is the compound that oxidizes in other metals to form rust. It is also lightweight, strong and can be 'cast' into many different moulds and shapes, so it's a great pick if you're looking for something decorative.
Powder coating is another effective method used to protect steel from rust. It is made up of a variety of different compounds, but it's the zinc that helps to repel the rust. Powder coating is applied as a dry powdered paint, which gives an appealing finish and lasts longer than liquid paint. It is the cheaper alternative making it a good option if you're on a budget but still want a good-looking letter box.
Companies have become very savvy when it comes to fitting more post into letterboxes. Some have a built-in newspaper slot for people who still adore print, while others come with extra depth to enable multiple letters. There are also those which are, simply put, 'built big' to cater for larger families who need more space for all sorts of letters and parcels.
Another key measurement to keep in mind is the size of the mail slot as this will determine how large a letter or parcel will be able to slip through, whilst still keeping it safe from thieves and the elements. For reference, a sheet of A4 paper has a width of 21 cm and a length of 29.7 cm, so if the slot is any narrower it might only be able to accommodate regular-sized envelopes.
It's a simple design feature, but a very useful one – a letter box with a small transparent glass or plastic viewing window will allow a quick and easy glimpse inside the container, putting an end to forever finding and fiddling around with your keys, only to open the box and realise in vain that it's empty. This handy design aspect tends to come with more modern letter boxes.
Some of the market-leading wall-mounting letter box companies have incorporated a marvellous idea to have your home address printed on the front before posting it out. This will help to ensure the postperson knows exactly where to put your letters, and can also help guests to find your house more easily.
If you're someone who loves the look of vintage and historical pieces in your home, then a decorative letter box could be for you. As mentioned, these colourful and purposeful letterboxes are usually made from cast aluminium, and come in an array of antique-looking and often quite striking designs.
The most popular styles are usually those which imitate Royal Mail post boxes or even post boxes from the Victorian era. They may not have all the mod cons of some of the more contemporary letterboxes, but they're sure to look the part if you're someone who likes to revel in the prestige of the past.
