What matters at the dock
- Close-fitting dock seals or inflatable shelters that limit temperature and humidity swings at the dock door.
- Door controls restricted to authorised staff using key switches, keypads or links to access control.
- Interlocks that keep dock doors closed unless a trailer is docked and secured by a restraint.
- Internal high-speed doors that separate the dock from controlled storage areas behind it.
- Dated service reports, repair records and inspection reports kept ready for quality audits.
Why is the loading bay a weak point for temperature control?
The loading bay is a weak point for temperature control because it is where controlled storage meets outside air, and every open door or poorly sealed trailer lets temperature and humidity change. Products stored at controlled ambient or chilled temperatures can be exposed while they wait at the dock.
Common causes of temperature swings include:
- Doors left open between trailers.
- Gaps around trailers from worn or poorly matched shelters.
- Staging areas just inside the door with no separation from the main store.
- Air leakage around levellers and pits.
Even a short exposure can matter if it happens on every trailer. Summer heat and winter cold both test the dock, so we look at how each bay is likely to perform in both, not only in mild weather.
Your temperature mapping may already show where the warm or cold spots are near the dock, and we use that information when recommending doors, shelters and seals.
How do you control who can open a dock door?
You can control who opens a dock door by fitting key switches or keypads to the door controls, or wiring them to your access control system, and by linking the door to the trailer restraint through interlocks. That keeps doors closed unless an authorised person opens them for a docked, secured vehicle.
- Interlocks can stop the door opening until a restraint is engaged.
- Door position contacts can feed your security or building management system.
- Solid insulated door panels limit sight lines into the store where security matters more than daylight.
- Dock traffic lights show staff inside when a trailer is secured and the door can be opened.
Security also applies to the vehicle. A restraint that holds the trailer until the door is closed and the paperwork is checked reduces the chance of a vehicle leaving before goods are confirmed.
Controls like these also help with temperature, because doors cannot be left open without a vehicle in place. See dock traffic lights and interlocks for options and guide prices.
Which shelters and doors suit controlled-temperature goods?
For controlled-temperature goods we usually recommend dock seals where the fleet is uniform and inflatable shelters where trailer sizes vary, combined with insulated sectional doors. Both seal more closely around the trailer than a standard retractable shelter.
Inside, a high-speed door between the dock and the store can act as a second barrier, so the main store is not exposed every time a dock door opens. This is useful where chilled and ambient products share a building, or where goods-in and dispatch use the same dock.
Where products must stay in a narrow temperature band, consider a dock area that is itself temperature controlled, so goods are staged in the same conditions as the store. The doors and shelters then protect that area rather than the whole building. Seals and shelter curtains should be checked at every service, because wear is gradual and easy to miss.
Our comparison of dock shelters and dock seals explains how each one fits around a trailer and which suits your vehicles.
What records will your quality team expect from dock maintenance?
Your quality team will usually expect dated service reports for each bay, records of defects and repairs, and evidence that inspection duties under PUWER are met. Clear records also support audits by customers and regulators.
- A written report after each planned service, listing checks made and defects found.
- Quotes and completion notes for every repair.
- Inspection reports for levellers and, where lift tables are fitted, thorough examination reports under LOLER.
- Records of safety device tests on doors, such as safety edges and photocells.
- Manufacturer's documentation and declarations for new equipment.
Change control applies to the dock too. If a door, shelter or leveller is replaced, your quality team may need to decide whether temperature mapping should be repeated, so tell us about any validation steps when we quote.

Questions
Can dock doors be linked to our access control system?
Yes, door controls can usually be fitted with key switches or keypads, or wired so that an access control reader must authorise opening. Door position contacts can also feed a security or building management system, so the control room can see which bays are open. We confirm what your system needs at survey and set out the wiring and interface work in the quote.
Is a dock seal or an inflatable shelter better for temperature control?
A dock seal is usually better where the fleet is a consistent size, and an inflatable shelter where trailer sizes vary; both seal closely around the trailer. Dock seals cost £1,100 to £2,600 per set and inflatable shelters £6,800 to £12,800 each, excluding VAT. Your vehicles, temperature ranges and how long doors stay open decide the right choice.
Will we get service reports we can use for audits?
Yes, every planned service ends with a written report for each item, listing the checks made, any defects found and recommended repairs with prices. Repairs are recorded with their own quote and completion notes. Together with the manufacturer's documentation for new equipment, these records give your quality team a clear history of every bay for audits.
