FAQ

Here at P.P. Group, we aim to provide you with innovative solutions using the latest processing technologies. Whatever you’re looking for, whether it’s information about our laser cutting services or specific details about areas such as Lumsden grinding or plate rolling, it may be that we already have the answer to your question.
Our expertise has contributed to successful projects across a range of industries, so take a look at our FAQ below and see if we have the information you’re looking for.
What is your laser cutting capacity?

We are able to cut materials such as stainless steel, carbon steel, aluminium, nickel alloys and duplexes up to a capacity of 6500 mm x 2500 mm x up to 25 mm. Our laser cutting will achieve a high quality finish with clean edging and minimal taper, prepared promptly to fit your required timeframe. The level of precision provided by laser cutting means we are also able to produce smaller, more intricate shapes where needed.

What is your plasma cutting capacity?

This will depend on the nature of the task. We are able to cut materials including stainless steel, nickel alloys and duplexes up to 9000 mm x 4000 mm x up to 150 mm.

In the case of HD Plasma, we can cut carbon steel up to 9200 mm x 3000 mm x up to 40 mm, with up to 45° bevel cutting. We can also prep the material for welding and rolling if required.

In all cases, our plasma cutting services can complete thicker items quickly and cost effectively.

What is your flame cutting capacity?

We have over 35 years of flame cutting experience, so you can be sure of a reliable, high quality service.

Our multi-head cutting method ensures we can quickly complete jobs up to a capacity of 17500 mm x 4500 mm x up to 300 mm. Your material can be custom-finished to your specifications using our Lumsden grinding and heat treatment services.

What is your water jet / bevel cutting capacity?

Our twin-headed water jet cutting method provides a cost effective process across a range of materials, including stainless steel, carbon steel, aluminium, titanium, copper, brass, bronze, nickel alloys, rubber and plastics. In practice, we can use water to cut any kind of free issue material.

The capacity for our high pressure water jet cutting services is up to 6000 mm x 3000 mm x up to 200 mm, with up to 45° bevel cutting.

What is your saw cutting capacity?

We can cut material such as stainless steel, nickel alloys, aluminium and duplexes up to a capacity of 6000 mm x 2500 mm x up to 150 mm.

Saw cutting is ideal for projects where non-standard bar sizes are required, and this method is perfect for giving your material a clean, straight edge.

What is your plate rolling capacity?

This will depend on the specific plate roller used. If needed, we can carry out edge prepping on your material so it is ready for welding once rolled.

We have four different roll sizes to choose from, each with varied capacities ranging from a thickness of 1000 mm x 3 mm to 3000 mm x 20 mm. Our experts will be able to advise you as to which would be the most efficient and cost effective for your project.

What is your press brake capacity?

We can employ one of four different types of press braking machinery, achieving a capacity of up to 750 tonnes at 6000 mm x 300 mm with our Bronx machine.

We have CNC-operated press brake machines, enabling us to handle complex drawings and run tests before carrying out the final pressing.

What is your edge / weld prepping capacity?

For P.P. Plasma and P.P. Profiles, 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.

For P.P. Protube, we can prep angles of up to 70° and materials of up to 50 mm in thickness ready for welding, reducing the time your project will take to complete.

What is your Lumsden grinding capacity?

P.P. Profiles’ 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 0.5 mm.

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 3700 mm, with a maximum height of 2070 mm.

Can you offer laser etching?

Etching is certainly available as part of our laser cutting service, and can significantly reduce fabrication time.

It is useful for a variety of purposes, including identification, traceability, stitch cutting, assembly, centre marking, hole positioning and bend lines. If you feel laser etching is something that could benefit your project, please speak to one of our experts.

What are your CAD development capabilities?

Our CAD technicians can lend their expertise and experience to a full range of 3D development tasks, including complex pieces.

We employ various software programs – including SigmaNEST®, Autodesk® Inventor® Professional and SolidWorks® – to achieve the design and consistency you require, providing a quick and cost effective solution.

We can work with a range of file and format types, including DWG, DXF, STEP, DWR, DWF and PDF. This is by no means an exhaustive list, so please ask us if you are unsure.

What type of plate, tube and box section stock do you have?

Our stock features a wide range of metals and other materials for plate and tube cutting.

P.P. Plasma can work with materials including stainless steel, aluminium, titanium, copper, brass, bronze, nickel alloys, duplexes, super duplexes, rubber and plastic.

P.P. Profiles provides 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.

What QHSE certifications do you have?

Our work and processes have been recognised under Quality, Health, Safety and Environment (QHSE) guidelines. Certifications we have achieved include ISO 9001, ISO 14001, OHSAS 18001, AS 9100 and BS EN 1090.

What are your welding capabilities?

  • Submerged arc column & boom 3.5 mts x 3.5 mts
  • Genset 320 amps
  • Arc air gouging
  • Coded welding to BS EN 287 & 288
  • Part 1, ASME IX
What testing methods are available?

Our P.P. Processing team provide a variety of non-destructive testing methods that will help ensure your material is fault-free and fit for purpose.

For example, hydro testing is used to monitor how your material responds to a given water pressure.

Dye penetrant testing will identify any surface faults in the material, and any issues highlighted can be ground out and re-welded.

In addition to our in-house techniques, we work with independent testers who observe various factors, from charpy impact to ultrasonic testing.

What is the maximum tube diameter and length you can profile?

We are the longest established tubular and box section profiler in the UK.

We can cut tubes ranging from 48 mm to 1225 mm in diameter. In addition, our MPC 1200 tubular and box section machine is capable of profiling tubes up to 14000 mm long.

What is the largest box section you can profile?

This will depend on the shape of the box section. For rectangular pieces, our capacity ranges from 60 mm x 100 mm up to a maximum of 500 mm x 450 mm. If you require square sections, we can profile from 60 mm x 60 mm up to 500 mm x 500 mm.

What is the thickest wall you can profile?

Our capacity here depends on the section being profiled. For rectangular and square sections, we can profile a wall up to 40 mm thick, while for circular sections we are able to work with walls up to 50 mm thick. In all cases, our minimum wall thickness is 2 mm.

Can you offer custom weld preps?

Yes, P.P. Protube can provide any custom weld detail required for your project. Our state-of-the-art machinery is capable of cutting parts with any weld detail required, saving you up to 30% on your costs.
