All cutting technology for stainless steel

Supplier specialized in stainless steel cutting, nickel alloys, titanium and aluminum, DVAI brings together, on the same site of production in France, cutting technologies allowing to realize your stainless parts: laser cutting, water cutting, plasma cutting or cutting by sawing (saw cut). One supplier for all your cuts and the assurance of getting the best delivery time with the best value for money.


Laser cutting for stainless steel

Today, many pieces for boilermaking industry, metalworking and industrial metalworking are cut with laser technology for a better precision. It’s another cutting technology available for our customers. DVAI has severals laser cutting machines with large format (2500mm x 6000mm) able to cut austenitic stainless steel, refractory stainless steel and duplex up 25 millimeters thick.
The stainless steel welding is of better quality when the pieces are cut with laser technology without draft. Equipped with ultra-fast lasers, it’s possible to make perforated sheets or stainless steel sheets with special perforations by limiting the deformations due to heating.

Water jet

Water cutting for stainless steel

Technology for cutting metal in a very wide range of thickness, the water cutting is a technology that DVAI naturally acquired. Equipped with a CNC machine with 2 cutting heads and a large format of 4 m x 14 m, DVAI workshop can cut any custom stainless steel pieces.


Technologie de découpe inox au plasma

Plasma (sometimes called oxycutting) is a technology that allows to quickly cut pieces of boilermaking industry that do not require high precision. With the latest generation of high-definition plasma.
304L stainless steel or other austenitic stainless steel (316L stainless steel, 316Ti, 904L, 321), refractory stainless steel (310S) or duplex stainless steel, all grades can be cut on our machines. So washers, disks, rectangles, all forms of pieces are achievable.


Saw cut

Other cutting technology, the saw cut is also a technology that DVAI can offer to its customers for cutting rectangular pavers. This is to cut the sheet with a circular saw blade that allows to make straight cuts in steel sheets. Highly used by mechanical customers, sawing is a way to make machined blocks simply. Indeed, it is possible to directly drilling, tapping or milling) on ​​sawn blocks because the faces are straight and of acceptable accuracy.

DVAI's stock

The vocation of DVAI is to provide in a timely manner, any piece cut to its customers. To do this, the company has a stock of stainless steel sheet and aluminum from 1 up to 60 millimeters thick. From this stock, DVAI offers the cutting of stainless steel sheets, nickel and aluminum alloys by means of different CNC machines.
DVAI a fait le choix de proposer un parc machine de découpe de plaque et tôle inox de grandes dimensions et de grandes capacités.

Cutting format :
2000 x 6000, 2500 x 6000 et 3000 x 6000 (laser cut),
3000 x 8000 (plasma HD),
4000 x 14000 water cutting.

Cutting quality stainless steel sheets

Whatever the technology used to manufacture your pieces, the same quality process ISO9001 V2015 is applied: each stage of manufacture is drawn and placed under the responsibility of serious and competent operators:
– Registering your cutting order in our
– Full contract review before cutting out
– Sending the order acknowledgment by fax or email
– Launch of the order in manufacturing
– Drawing or recovery of pieces according to the provided files (DXF or DWG)
– Production and cutting of pieces
– Marking report on all pieces debited according to our internal procedure
– Pieces preparation : deburring on the underside to eliminate defects and avoid any risk of injury or breakage in your workshops. For the safety of your operators in reception and assembly all pieces delivered by DVAI are deburred.
– Final inspection before shipment : dimensional inspection, marking report
– Packaging of the order: all the pieces are packaged, the pallets are filmed with heat-shrinkable plastic and marked with Scotch tape, the order number is written on the packaging
– Shipping: 3 modes of transport are used daily: express transport, national courier and specific charter.
