Grinding Service
Surface grinding (or Lumsden grinding) allows standard thickness sheet and plate to be ground to your custom thickness. Our three Lumsden grinders maintain flatness over considerable length, ensuring that dimensions of your profiles remain accurate.

Lumsden Grinding To Your Specific Thickness
Our machines can work to close tolerances, without leaving witness lines; and with a higher rate of material removal in comparison to conventional surface grinding. Please get in touch to discuss your project requirements: we can work with one-off samples right through to major batch runs.
Accuracy
Achieve tight thickness tolerances down to 0.1 mm and flatness within 0.5 mm for accurate, reliable profiling.
Speed
High material removal rates and in-house heat treatment reduce turnaround times and keep projects moving.
Consistency
Three grinders ensure flatness is maintained over considerable lengths, giving you consistent results across every part.
Quality Finish
Create profiles with a clean, uniform finish suitable for both functional and visual applications.
Flexibility
Grind to your required thickness between 6 mm and 200 mm, whether for single samples or large batch runs.
Fast Delivery
Benefit from a 1 to 2 day turnaround and premium delivery across the UK and Ireland using our dedicated fleet.
Delivering Quality Products With Precision For Decades
"P.P. Group offered a completely different approach to our standard manufacturing methods. Adopting the latest advances in CAD software and profiling technology helped us to reduce costs and dramatically increase profitability. I would highly recommend contacting one of their Sales team to discuss what benefits P.P. Group’s advanced CAD and cutting technologies can bring to your business."
“P.P. Group managed to profile and deliver 75 tonnes of parts within five working days, which enabled us to meet and exceed our project’s deadlines. In addition, we saved significant time on drilling due to 40 mm cut holes, provided by P.P. Group during this task.
This truly flexible and swift approach, enabled us to deliver all the tunnel cutting machines for the construction of railway lines on time.”
“P.P. Group's advanced facilities and machinery enabled us to successfully manufacture a very complex baggage shield that weighed 76 tonnes for Heathrow Airport Terminal 5.”
“P.P. Group was able to supply us with materials, to manufacture six stainless steel filters, for the waste water industry. Each of these filters was 14 m x 4 m x 6.5 m high, consisting of thousands of profiles/parts, which were laser and water jet cut, as well as rolled and pressed; in as little as just four months. Due to the short lead time of such a large order, the project won a recognised global award.”

FAQ
What is your edge/weld prepping capacity?
The bevel angles can vary from 22.5° to 55°, with a plate thickness of between 6 mm and 50 mm. The maximum bevel depth will vary depending on whether you are using carbon or stainless steel.
What is your Lumsden grinding capacity?
Our 2540 mm Lumsden grinding table can finish profiles ranging from 6 mm to 200 mm in thickness. Three grinders are used to achieve consistency even across larger profiles, with a flatness tolerance of 0.25mm.
We also have the capacity to grind magnetic stainless steel, if needed.
What is your heat treatment capacity?
Our heat treatment offers stress relieving and normalising functions, which help us to prevent instances of metal cracking or splitting.
Our ovens are able to treat materials up to a capacity of 3800 mm x 3500 mm.
What type of stock do you have?
Our stock features a wide range of metals and other materials for plate profiling. We can work with materials including stainless steel, aluminium, titanium, copper, brass, bronze, nickel alloys, duplexes, super duplexes, rubber and plastic.
We also provide materials manufactured to fit the requirements of your project, including carbon steel, abrasion/wear resistant and weathering resistant materials, as well as heat treated, quenched and boiler grade steel.
Please consult our website/brochure for a full stock list, or ask our team if you require further clarification. Keep in mind that we can also cut free issue material where required.
