All orders will be acknowledged on receipt by email or (where no email address is supplied) in writing and will include an estimated date for completion.

Our preferred method of delivery will vary depending upon a number of factors including the weights of individual items in the consignment and the delivery address. The delivery method will be stated in our Order Confirmation. The usual methods of delivery for items up to 35kg and those exceeding 35kg are detailed below but please be aware that different arrangements may apply to remote areas and offshore islands. Exceptionally, if the size of an individual order or the mileage involved warrant it, we may opt to use a dedicated courier.

Orders where no single item exceeds 35kg are usually despatched via a UK nationwide courier on an overnight service, i.e. the consignment leaves us one day and you receive it on the next working day (Monday to Friday). As soon as your order is completed, we will contact you to arrange a suitable delivery day when someone will be available to receive it. All deliveries require a signature. Please note that this is NOT a timed delivery service and delivery could occur any time between 08:00 and 17:00 on the chosen day.

We appreciate that there is nothing more frustrating than having to set aside a whole day to receive a parcel, so if this is an issue, there are a number of possible work-arounds.

Firstly, it is generally possible to request a before 12:00 or before 10:30 delivery slot but this will attract an additional charge. If a timed delivery is essential please call us on 01280 701093 to place your order.

Secondly, it is sometimes possible for us to get the driver to contact you, say 30 minutes ahead of delivery, with an estimated arrival time. This is sometimes useful for deliveries to churches, village halls etc when you are close-by but not at the delivery location. It must be stressed however that there is no contractual obligation for the courier to do this and whether or not it happens will depend upon the goodwill of the driver concerned.

Thirdly, exceptionally and not recommended, it may be possible for you to nominate a “safe place” where the parcel can be left without being signed for but please be aware that in choosing this option, you assume full responsibility for the condition of the item as delivered as no claims for damage can be entertained for items received without a signature.

Orders where one or more items exceed 35kg are usually delivered by a specialist 2-man delivery team. As soon as your order is completed, we will contact you to let you know that it is being collected by our chosen specialist courier and shortly thereafter they will contact you directly to make final arrangements for the delivery.

Are all doors lockable?

Yes, all doors are top-hinged and lockable. Each A-Max board is supplied with 2 keys.

What is the expected lifespan of an aluminium noticeboard?

All our aluminium noticeboards are designed to give many years of troublefree service whilst requiring minimal care. Like any other product however, a little preventative maintenance such as regular lubrication of hinges and locks can help prolong the board’s useful life.

Which Display panel option should I choose?

For details of each option and its benefits simply choose that option from the dropdown and hover over the ? symbol that appears next to its price.

Toughened glass v. polycarbonate – which is better?

It depends upon the circumstances of the individual installation. Toughened glass is heat-treated and typically has a strength 4 – 6 times that of the equivalent ordinary float glass. When it breaks, it tends to shatter into small pebbles that are relatively innocuous (like an old fashioned car windscreen). Polycarbonate is a tough plastic material, as used for the production of items such as police riot shields. It will cope with far greater impacts than will toughened glass but, being a plastic material, has a softer surface and is therefore more susceptible to being scratched.

Which way do the doors hinge?

All doors on A-Max cases are top-hinged and assisted/supported by gas stays, when open.

What is the lifespan of digital print?

Digital print has a minimum expected lifespan of 5 years. This doesn’t mean that it will be life-expired after 5 years but that we would not expect to see any noticeable deterioration in colour within a five year period. When used in a g.r.p. encapsulated panel it creates UV fade-resistant panel capable of withstanding external conditions for more than 10 years.

Can I make minor changes to contact details, service times etc on a sign panel?

Sign panels (as opposed to digital print and encapsulated panels) have lettering applied in computer-cut vinyl. Whilst this is designed to be weather-proof and permanent, there is a technique for removing it, if you know how! This means that making minor amendments, such as a change of contact number or service times is easily accomplished. We can supply new lettering to match the original for you to apply on site without the need for the board to be returned to us.

What artwork do I need to provide for logos or graphic panels?

For detailed information on acceptable file formats for logos and guidance on generating suitable artwork for graphic panels, maps etc., please click here for our separate guide on the subject.


Are all doors lockable?

Yes, all doors are lockable. Each A-Max board is supplied with 2 keys.

What about lighting?

LED lighting is available for all A-Max noticeboards.

LED lighting requires connection by a qualified electrician to comply with applicable safety regulations.

What about installation?

Installation is designed to be as straightforward as possible and should be well within the capabilities of anyone competent at DIY. All aluminium boards are supplied with instructions and post-mounted versions come with the necessary fixings. We recommend that posts for post-mounted boards are concreted into the ground to a minimum depth of 600mm.

The majority of our customers either undertake installation themselves or arrange for it to be carried out by a local contractor as this generally proves to be the most cost-effective method.  We are however able to offer an installation service covering much of the UK if required. If this is of interest, please call us on 01280 701093 for details.

Can I get spare keys?

Yes, they are available from stock and can usually be posted out to you the same day.

10-year Guarantee:

Each A-Max aluminium noticeboard comes with a 10-year guarantee on the quality of workmanship and materials used. We guarantee to the original purchaser that boards are free from defects in material and workmanship. “Defect” is defined as any imperfection which impairs the normal use of the board. This guarantee is expressly limited to the labour and material costs of repair within 10 years of the date of despatch and excludes the following:

1] Defects caused by the improper assembly, installation or disassembly.

2] Defects occurring after purchase as a result of lack of maintenance as prescribed in the relevant maintenance instructions, unauthorised product modification, intentional damage, misuse, abuse or negligence.

3] Cosmetic damage.

4] Labour costs incurred in returning the board to us.
