Grit, Salt Bins & Snow De-icers

A grit and salt bin provides weather-resistant outdoor storage for rock salt, de-icing salt or grit. Positioning a bin close to entrances, paths, steps, car parks and service areas makes winter supplies readily available when frost, ice or snow is forecast.

What size grit bin do I need?

Choose the capacity according to the area you need to treat, how frequently it is used and how often you can refill the bin. A compact 50-litre bin is useful for entrances and short paths, a mobile 75-litre bin helps staff cover several locations, while 130 to 200-litre grit bins are better suited to car parks, private roads and larger commercial premises. Always check each product’s stated litre and kilogram capacity before ordering, as these measurements are not interchangeable.

Where should a grit bin be positioned?

Place it on firm, level ground close to areas most likely to become slippery, without obstructing pedestrians, vehicles, emergency exits or accessible routes. Priority locations commonly include building entrances, pedestrian walkways, steps, ramps, car parks, shaded areas and places that remain damp. The bin should also be safely accessible to the people responsible for gritting.

When should paths and car parks be gritted?

The Health and Safety Executive advises gritting when frost, ice or snow is forecast, or when wet or damp surfaces are likely to reach freezing point. Applying salt early in the evening before frost settles, or early in the morning before staff and visitors arrive, gives it time to dissolve and start working. Avoid relying on air temperature alone, as the ground surface can be colder.

What is the difference between grit and rock salt?

In winter-maintenance use, the word “grit” often refers to rock salt, although true grit, sand or aggregate mainly improves traction. Rock salt works as a de-icer: it forms a brine that lowers the freezing point of water, helping to prevent ice forming and melt existing ice or snow. Check the product description to confirm which material you are buying or storing.

Do grit bins keep salt dry?

Outdoor grit bins are designed with close-fitting or sloping lids to protect their contents from rain and snow, helping to reduce moisture, clumping and material loss. Keep the lid closed between uses, inspect it regularly and avoid placing the bin beneath leaking gutters or where standing water can collect.

Should I choose a lockable grit bin?

A lockable grit bin is useful in public or unsupervised locations where unauthorised use, contamination or theft may be a concern. Check whether the chosen product includes a lock, has a hasp for a separate padlock, or is supplied without a locking facility. Make sure authorised staff can gain quick access when freezing weather is forecast.

Are mobile grit bins suitable for commercial premises?

Yes. A wheeled grit bin can be moved between paths, car parks and harder-to-reach areas, reducing repeated journeys to a fixed storage point. Mobile models are particularly useful across larger hospitality, education, healthcare and workplace sites; check the wheel type, handle design, filled weight and route conditions before use.

Are grit bins supplied with salt and a shovel?

It depends on the product. Some grit-bin kits include bags of de-icing or brown rock salt, and selected heavy-duty models include a shovel, while other bins are supplied empty. Read the individual product description carefully so you know whether salt, grit, a scoop, shovel or padlock needs to be ordered separately.

How should a grit and salt bin be maintained?

Inspect the body, lid, hinges, lock or hasp and any wheels before winter and throughout periods of cold weather. Remove contamination, break up or replace badly compacted material, keep the lid shut and replenish stocks before supplies run low. When the season ends, empty and clean the bin if required; stackable models can be stored more efficiently when empty.

Does having a grit bin replace a winter safety plan?

No. A grit bin supports a wider winter risk-management procedure but does not remove the need to assess hazards, monitor forecasts, identify priority routes and assign responsibility for treatment and stock checks. Where an area cannot be treated safely, consider restricting access or directing people to a safer route until the hazard has passed.
