Quick answers to the questions we're asked most. Can't see yours? Our team is happy to help.
Ordering and quotes
How do I get a quote?
Choose the products and quantities you need with Add to Quote on any product page, then send your quote from the Quote page. No account needed. We aim to reply to all quotes within 1 hour; please allow up to 24 hours during busy periods.
What if I need something you don't list?
Every product page has an Anything custom? box. Tell us what you need there, for example bespoke badge wording, or a size or finish we don’t list, and it’s added to your quote for our technical team to confirm with you. Optional extras such as venting are confirmed the same way.
Can I buy through a merchant?
Yes. If you’d rather buy through a merchant, get in touch and we’ll point you to one. Merchants who would like to stock our range can apply through the contact form: choose Distributor application.
Delivery
How quickly do you despatch?
Orders placed before 12pm on a working day are despatched the same day, with next-day delivery available on request. Special options such as badging, locking and sealing take 5 to 7 working days.
Can I track my delivery?
Yes. Every order comes with delivery tracking, progress updates while it’s on the way, and proof of delivery. We also offer free tail-lift offloading on request, and our fleet is FORS-accredited.
Products and standards
Which load class do I need?
BS EN 124-2 sorts covers and gratings into load classes by where they’re installed:
- B125: footways, pedestrian areas and light vehicle areas
- C250: car parks and kerbside
- D400: carriageways (roads)
- E600: very high wheel loads, such as docks
- F900: the heaviest loads, such as airports
If you’re not sure, ask our technical team.
Are your products Kitemark certified?
Yes: every applicable Thomas Dudley product is independently Kitemark tested, and our range is designed to BS EN 124-2. Our certificate numbers are on the Certifications and Standards page.
What is the CD534 range?
Our CD534 range is designed to fully meet, and in several respects exceed, National Highways’ CD534 requirements (formerly HA104/09) for trunk roads and motorways. That includes a skid resistance value of 78 PSRV against a 60 PSRV minimum, and a minimum frame depth of 150mm.
What is the lift-out hinge?
Our patented lift-out hinge is fitted across our D400, E600 and F900 covers and gratings. It opens to 135° for safe, one-person operation on most sizes, and where full removal is needed, for man-entry access for example, the cover can be lifted out completely.
Can I see a product being tested?
Yes. Every product is load tested in our own facility, which can apply up to 999kN. You’re welcome to visit and watch us test any stock product you choose, and we’ll test a competitor’s product you bring for free. Because testing is destructive, we replace any Thomas Dudley product we test with one from stock, delivered to your site free.
Technical information
Where do I find datasheets?
Every product page links to its datasheet, and the Technical Resources page lists them all by category, along with our guides and brochures.
