V Grooving and folding of sheet metals
Creating precise, sharp angles and folds with V-Grooving machinery
Bending metal using a V-Grooving machine allows it to be folded to a tight radius, or sharp corner. This enables folded metal to mimic solid bar material at around a tenth of the cost and also avoids wastage. V-Grooved profiles look just like solid bar material but are light in weight and easier to transport and install.
We can V-Groove and fold up to 4 metre lengths of material and thicknesses from 0.8mm to 6mm.
The V-Grooving machine in action
Depending on the thickness of the material and the type of fold required, the V-Groove machine cutting head will run a programmed number of times along the sheet material.
A way to achieve cost-effective high-specification finishes for today’s architects and interior designers
Architects aiming to achieve upmarket, high-specification interiors and finishes rather than specify solid materials can utilise V-Grooved folding. This method of creating solid-looking trims, architraves and skirting enables endless design options.
Using PVD stainless steel, the V-Grooving process is used to create colour-matched display fixtures, fascias, curtain-walling and cladding.
Where initially a solid metal has been considered for a project this can be value-engineered to V-Grooved profiles with no loss of aesthetic. For boutique hotels and luxury retail brands these lightweight V-Grooved profiles are a cost-effective alternative.
For exterior cladding and curtain-walling V-Groove folds allow for seamless butting-up or can create decorative shadow gaps.
V-Grooving is also called score-folding, V-cutting and back-scoring.
A selection of architectural applications for V-Grooving and folding
Button panels, cladding, trim and architrave are created from V-Grooved and folded metals.
Interior panelling and cladding
PVD stainless steel sheet is V-Grooved and folded to create escalator side and base panels to enable close butting-up for a visually seamless effect.
Washrooms, cubicles and bathroom trims
The cubicle doors in this washroom have been created using PVD coloured stainless steel in Rose Gold Hairline.
Elevator cab interiors
V-Grooved and folded PVD coloured stainless steel in Nickel Hairline and Chrome Vibration for elevator cab interior with Brass Mirror detailing and Chocolate Vibration frieze and kickplate.
Exterior cladding detail
These decorative brise soleil fins and exterior panels are created using V-Grooved and folded PVD coloured stainless steel in Chocolate textured stainless steel. The edge-folds give depth and the look of a solid material.
Hotel and restaurant, glass racks, bars and fittings
V-Grooved and folded stainless steel creates the appearance of solid brass bar for this overhead glass rack.
What does V-Grooving do?
V Grooving creates decorative grooves, channels and shadow gaps.
V-Grooving allows for sharp bends to be created from sheet material creating profiles that give the appearance of a solid material.
Solid, or bar, metal is both more expensive to purchase and creates wastage once shaped. Bending sheet material is a more cost-effective alternative.
PVD coloured stainless steel can be V-Grooved and folded without any damage in appearance to the PVD coating. Therefore PVD sheet material is ideal for V-Grooving and folding as a cost-effective alternative to Brass, Bronze, Copper, Gold and Iron.
Benefits of V-Grooving
Speed – a V-Groover can machine more grooves in one hour than a traditional milling machine or router can perform in eight hours. This means it is cheaper in the cost of labour and large volumes can be handled in relatively quick timescales.
Accuracy – the V-Groover is set to a highly accurate measurement – so much so that a grooved sheet could be put through a second time with no deviation or alteration to the first groove. This means very precise and small profiles can be fabricated.
Channelling out solid bar material creates waste from an expensive commodity. V-Grooving and folding creates minimum waste and is on average a tenth of the cost of working with solid bar metals. Precision folding – V-Grooving allows for folding to a tight radius, creating sharp bends.
V-Grooved and folded profiles in appearance look as if they are cold-drawn or extruded metal.
Groove shape options
V-Grooving can be created not just in one shape of V. Wider V, semi-circular and square grooving is also possible allowing for a range of design variations.

Examples of V-Grooved and folded profiles in Double Stone Steel Bronze PVD coloured stainless steel
The following materials can be V-Grooved and folded
PVD coloured stainless steel
PVD (Physical Vapour Deposition) coloured stainless steel is a sustainable alternative to anodising and electro-coating both of which involve chemical baths. PVD coloured stainless steel is created through the use of heat and gas and produces no waste products.
Stainless steel can be folded after PVD colouring without cracking or fissuring.
Textured stainless steel
Textured stainless steel brings another dimension to specifying PVD coloured stainless steel. The range of embossed, surfaces provide tactile qualities as well as reflecting light in subtle ways which add to the creative possibilities when designing with this material.

Cor-ten or, or weathering steel, is designed to develop a rusty patina, be corrosion-resistant and, of course, not need painting or touching up.
John Desmond Ltd have formulated a specialised method of accelerating the development of the patina. This means that fabrication can be carried out in this material and yet meet commercially viable timescales.
Contact Alex via [email protected] to ask about patinated brass for your project.
Left untouched, all brass would develop into patinated brass. However ready-patinated brass created by John Desmond Ltd already has an aged, richly-toned surface and is stabilised in appearance with the application of a natural sealant.

Blackened stainless steel
The blackening of stainless steel actually increases its corrosion-resistance however is mostly specified for its gleaming appearance not easily achieved through other methods.

Vibration stainless steel
Vibration finish stainless steel is a versatile finish for stainless steel being non-directional and relatively un-reflective. It is one of a range of finishes on stainless steel offered by John Desmond Ltd.
Shot-peened stainless steel
Shot-peening, also known as sand-blasting, increases the longevity of steel and is commonly used for aeronautical components. However it also has an interesting and versatile non-directional appearance and is consequently specified for its aesthetic as well as its relative non-reflectancy.

Aluminium is a lightweight and corrosion-resistant material and through the process of anodising can be transformed into a range of coloured finishes.
The laser-cutting of stainless steel combined with PVD colouring and V-grooving provides a multitude of creative possibilities for interior and exterior applications.
