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.

See comparison of V-Grooved and folded profile with non V-Grooved profile

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.

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

No wastage

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.

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.

Groove shape options

V-Grooving can be created in a broader “V” as well as other shapes. In other words a V-Groove can be a U-Groove or even a Square Groove enabling a range of design variations through the radii of the folds.

Creates small, fine-detail profiles

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.

A cost-effective Aesthetic

V-Grooved and folded profiles in appearance look as if they are cold-drawn or extruded metal. This gives the impression of a solid bar and high-quality finish whilst being cost-effective, lighter in weight and cheaper to produce.

Precision enabling design options

Precision folding – V-Grooving allows for folding to a tight radius, creating sharp bends enabling a matching set of profiles across a range of applications such as fascias, architraves, skirtings, sockets and bar and counter-top frames.

The following materials can be V-Grooved and folded

PVD coloured stainless steel

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.

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.
