Grit Bins

Mini Grit Bins

If you are a home owner with limited outdoor space that you would like to grit when there is ice and snow on the ground, then mini grit bins were made for you. Most of us are used to the large grit bins that you sometimes see at the side of the road or in the courtyard of a block of council flats, and sometimes in the grounds of a large company. Roadside and courtyard grit bins are the property of the local authority in a given area and they are placed in locations where the gritter does not go. Generally speaking members of the public or flat residents are expected to lay the grit on smaller areas or in the courtyard of a block of flats.

Grit bins come in a variety of shapes and sizes, with the largest grit bins holding around 500 litres or 250 kilos of grit while the more recent mini grit bins will take only thirty litres or fifteen kilos of grit. Many home owners will have either stackable grit bins, one for the front and one for the back of their house that can be stacked together and stored away when winter is over, or the small, fifty litre grit bins. If you purchase one of the mini grit bins for some homes, then you would find yourself having to refill the grit bin on a regular basis, which could prove a problem.

The Process of Gritting

Grit bins contain the substances that make it safer to walk on paths and pavements and less dangerous to drive when there is ice and snow on the ground. All grit bins, including mini grit bins usually contain a mixture of grit or sand and rock salt. When grit is spread over ice and snow it helps to increase the friction between the tyres of a vehicle and the road underneath, giving the tyres more grip in icy conditions. Salt is used as antifreeze because it lowers the point at which ice freezes, unless the temperature goes below minus five degrees centigrade, when the ground needs to warm up again before the salt can do its work. Sea salt is too fine and dissolves before it can melt the ice so rock salt is used instead. Local councils use gritting machines to spread the grit on major highways and gritters are also used in airports to clear the snow from the runway. A different type of salt is needed for airport runways because the properties of rock salt can damage both the framework of an aeroplane and its delicate navigation systems.

What are Grit Bins Made From?

Nowadays most grit bins are made from hard plastic because less damage is caused if a person or an individual collides with the bin and because it is a durable, non-corrosive and weatherproof material. Hard plastic is used for all types of grit bins, including mini grit bins. Most plastic grit bins, including mini grit bins will have sloping lids so that the rain just slides off them.
