Latest Case Study - Grenville’s window to success

Grenville Engineering is a leading sheet metal fabrication company who has always taken pride in its long standing relationships.

One such successful partnership is with a prestigious company in the Housing industry. Since the inception of the collaboration with the customer in 2000; Grenville has produced a number of bespoke fabrications of windows made in mild steel, aluminium and stainless steel in addition to their standard ranges.


The Brief

Grenville was approached by a leading steel window manufacturer to fabricate 48 trapezoidal roof windows for a major restoration project of a Grade II listed Roundhouse in the East Midlands.

A major challenge to overcome was that each individual roof window was required to be customised with a variations in dimensions and angles, to allow each roof window to perfectly fit around the hip of the circular roof.

The project was also to be completed within a very strict time frame.

Our Approach

As the preferred provider, Grenville had the expertise and capability to complete a complex project of this nature. A project team was assigned from the planning department through to shop floor to ensure full focus was given. A dedicated Planning Engineer worked in conjunction with the client’s Design Team to ensure each unique roof window was manufactured to specification via 3D CAD software.

Once the 3D design was signed off, the bespoke roof window was manufactured using a combination of fabrication services. The stainless steel material was cut using a Trumphf laser then pressed by a Bystronic press brake, welded and assembled as per the specification. The progress of the project was easily traceable through the advanced ERP system. Inspections were carried out at each manufacturing process to ensure that the end product was exactly as per the client’s requirements and in compliance with their 10 year guarantee.

The Outcome

The bespoke project was a resounding success with both the client and their end customer being delighted with the standard of work and prompt delivery. In addition it strengthened the relationship and cemented Grenville’s status as the client’s preferred provider for all bespoke projects.

Our long standing relationship with Grenville Engineering, based on their ability to handle a technically complex project brief to a consistent quality standard, provided us with the reassurance that they could support us on this prestigious project.

All phased deliveries met the required deadlines, maintaining a continuous supply over the contract period in line with our client’s desire to complete each stage to their project schedules.”

The Brief

The client approached Grenville to manufacture a bespoke bag filter for a high profile customer within the plastics industry.

The  unit specified by the client  was a multi-compartment dust collector, located externally to the main production facility.

The client provided a drawing with 35 components working to strict tolerances and sizing specifications. Adhering to the exact requirements was critically important as  the filter unit was designed in a modular format from individual panel sections and was assembled on site thereby requiring an extremely high degree of accuracy.

Grenville were provided with a 2 week lead time, dictated by the end customer. This was a challenge due to the level of complexity and assembly work involved.

Our Approach

Grenville’s planning department were provided a PDF drawing of the complete project and a dedicated planner was assigned to lead the project so that components could be produced through our state of the art laser machines and press brakes.

Due to the complexity and size of the project a number of engineers were allocated utilising their industry knowledge and capabilities to ensure the complete job was manufactured to the exact requirements of the client. The nature of the work involved highlighted Grenville’s capabilities as a complete fabrication provider including laser cutting, bending, rolling, welding and assembly. An assembly line was created with a dedicated workspace to ensure the smooth transition of each part during the fabrication process.

Rigorous inspections were carried out during each fabrication process ensuring the assembled project conformed to the specifications detailed within the drawings.  Maintaining the integrity of the drawing was vital to comply with the technical functionality of the filtration system.

The size of the overall project was a key factor to consider for the despatch department, each component carefully packaged in sections to assist the client in final assembly on site.

The Outcome

The dedication and effort showcased by Grenville Engineering was commended by the client. In addition to completing the project within the 2 week lead time, the quality of each component was exemplary, pivotal to the successful performance of the dust filtration system.
