At Manthorpe we have secured a reputation for the manufacture of high integrity fabrications used in Power Generation, Process Plant and Engine Test Facilities. During 2013 Manthorpe replaced the existing fabrication shop with a new purpose built facility that has an internal footprint of 76m long by 29m wide with an under the hook height of 10.2m.

The new facility is fitted out with 2 off 50 tonne cranes, whilst the building was designed for a 100 tonne tandem lift at 6m crane centres giving us the ability to manufacture fabrications up to 100 tonnes, this now allows us to fabricate very large, high integrity components for a range of precision industries.

Manthorpe has experience in producing bespoke high integrity fabrications in carbon steel, Weldox, Duplex, Super Duplex, stainless steel and Aluminium, all carried out in house by our experienced work force.

Manthorpe Engineering is certified in line with Management System as per BS EN ISO 3834-2:2005 – Quality Requirements for the Fusion Welding of Metallic Materials – Comprehensive Quality Requirements and has also gained accreditation to EN 1090-1:2009+A1:2011Exc 4 enabling us to manufacture and CE mark structural steel components at the highest level.

High Integrity Fabrications of All Sizes

We have manufactured items ranging from small brackets, right through to large complex trenching machine chassis that are over 8m long and require proof load testing to 95 tonne upon completion of the manufacture.


Experienced In Fabricating a Wide Range of Materials

Manthorpe has experience in producing bespoke high integrity fabrications in carbon steel, Weldox, Duplex, Super Duplex, stainless steel and Aluminium, all carried out in house by our experienced work force.

Our welders have had additional training  due to the restriction required when working in duplex; the restrictions in heat input allowed. We carry out job specific weld tests to suit the customer requirements. 

The image on the right shows a bespoke high integrity tubular assembly manufactured from rolled tube and plates in carbon steel.

This unit was set out by our experienced fabricators before being loaded onto a 10 tonne welding manipulator to enable all welding to be carried out in the flat position in a controlled manner and sequence to avoid distortion and twisting.

All welds were then subject the NDT before being released to the customer.

Jig and Fixture Design for Highly Detailed Components

Manthorpe were issued with a rather old drawing to produce a replacement component for Greenray turbines. Working in conjunction with their engineers, we came up with a solution as to how to jig up the components for manufacture.

Our engineering team then produced stage drawings for the piece parts and the fixtures required. Then the parts were all pre machined in house before being issued to the fabrication department.

Our experience of designing and manufacturing fixtures and tooling to optimise the manufacturing process means we can always offer reliable and quality supply.

The rings were set onto a jig and then each vane had to be trial assembled into its slot and shimmed until all the vanes were in position, before being checked with slip blocks for true position.

Once everyone was happy, the vanes were welded in sequence to avoid distortion and then inspected with slip blocks again.

The final machining was then carried out in house, allowing Manthorpe to produce the component from start to finish.

Over 30 Years of Experience

With over 30 years knowledge in the manufacture of high integrity fabrications, we have an excellent reputation that stems from our ability to handle and control ambitious projects across a wide range of engineering disciplines.

With our extensive experience and well equipped manufacturing facility, we provide a comprehensive service for the manufacture of bespoke engineering solutions for our customers. 

Reliable Delivery Solutions

Whatever your delivery requirements, you can be sure that our robust project management procedures will give you confidence in our ability to not only meet, but exceed your expectations. Project deliverables will be managed from our extensive in-house facilities, ably supported by a network of qualified and experienced sub-contractors with a first class capability to provide the right technical solution.
