ISO accredited experts in Outsource Manufacturing, we at Greenfold Systems Ltd (GSL) work with our customers to provide them with creative solutions to problems throughout the outsource process.  From building double-decker buses to vertical farms, from electromechanical assemblies to precision engineered fabricated parts, GSL has all the services you would expect to see from a best-in-class provider.

There are many great sheet metal companies in Scotland and the UK.  There are also several great wiring houses.  To differentiate itself, GSL set out to do what other mainstream providers “don’t do, can’t do or won’t do”.

You may already have a supplier for design, a supplier for metalwork, for wiring, painting and so on.  Each with their own point of contact.  Each with their own profit margin.  Each with their own lead time, their own PO and paperwork etc.  It is GSL’s goal to streamline this process and to compliment your supply chain, providing you with a turnkey solution to outsource manufacturing.

With a combined manufacturing space of over 100,000 sq. ft at various sites across the UK, we want you to think of our business as an extension of your company.  After all, the more successful we make you – the more successful you make us.  It is this unique approach to contract manufacturing that has saw us go from strength to strength throughout our history, with plans to grow and innovate further still.

'From the manufacture of bespoke metal fabrications and cable assemblies, to the complete fit out of the bus internal livery, GSL Bus division offers a low cost outsource alliance that differs from traditional sub-contracting.

Strategic outsourcing allows our customers, who are market leaders, to focus on throughput and quality. Our solution offers customers the option of managing fewer staff and using the flexibility and cost benefits that outsource offers. Through this strategy GSL manufactures major high level assemblies such as Chassis Sides, Roofs and Inter Decks on Double deck bus variants, and Sides and roofs on Single deck options. Our experience includes the fit out of flooring, glazing, seating, doors, poles, destinations and cove panels.

In addition, we manufacture and assemble other integral bus parts on a full turnkey basis; items such as Front window frames, Rear window frames, Luggage racks, Stowage racks, Engine door covers, Seat risers and Bumpers, Destination panel and Driver cab support frames, and Battery support frames. These are all good examples of how we compliment our customers' expertise in coach and bus finishing.

GSL Rail

GSL Rail heads up all Rail-related operations in our business.

Currently, one of our bigger refurbishment programs is on Northern Rail, where we supply kits for Wheel Slip Protection.  This means we offer a service where we manufacture components that constitute a kit where we supply just in time, both manufactured components and bought-out components.  So, for example, we would make wires, cables, harnesses, brackets, enclosures, etc. and combine those with an AVL parts list that we procure.  It’s a fully kitted, turnkey solution delivered to your desired location, just in time.

Other examples of current projects include HVAC, LED lighting, Replacement doors, Wi-Fi and CCTV.

More recently, GSL has been busy providing both metalwork and wiring for Scotland's first Hydrogen Train.
