LE RAIDISSEUR is a U-section steel worktop and table top stiffener designed to counter the natural movement of wood and prevent warping over time.

Manufactured in the Ripaton workshop in Montpellier, it is made from 3 mm-thick U-profile steel (section 20×40×20 mm), available in 4 lengths - 600, 700, 800 and 900 mm - to suit all table tops solid and finger-jointedwood.

The fine-textured matte black powder coating ensure humidity resistance suited to indoor environments and sheltered outdoor spaces - terrace, balcony, garden table.

Its oblong holes (16×8 mm) enable direct screw fixing: the oblong holes allow screws to play in the direction of the grain, eliminating the risk of cracking solid wood and ensuring flexible assembly on all table top configurations.

For table tops, where a central support is required in addition to the reinforcement under table top, see also our knock-down table frame with central crosspieces.


Preserving a solid wood or finger-jointed wood table table top

Wood is a living material: it works, swells and shrinks according to ambient humidity. Over a length of 60 cm or more, this natural movement is reflected in progressive bowing or warping at the end of table top.

To counteract this phenomenon, it is necessary to add a reinforcing profile under the table top. THE RAIDISSEUR acts as an invisible reinforcement - no milling, no complex tooling - that maintains flatness while allowing the wood to breathe freely thanks to its oblong holes.

Protect table tops for gardens, balconies and terraces

Bulging and warping on garden tables are a thing of the past.

LE RAIDISSEUR's powder coating gives it the moisture resistance required for sheltered outdoor environments. Under a terrace table or balcony surface exposed to variations in temperature and humidity, it maintains the flatness of table top season after season, without any special maintenance.

Positioned under table top, LE RAIDISSEUR is completely invisible from the living area.

Its 20×40 mm U-shaped section is discreet enough not to interfere with knees or the aesthetics of the room, while ensuring structural rigidity.

Rigidifying a kitchen worktop - the kitchen designer's tool

In a fitted kitchen, the worktop is subject to constant stress: repeated loads, thermal variations, humidity.

In the case of long spans - central island, snack plan or L-shaped kitchen with no intermediate support - progressive sagging is a design flaw that the kitchen specialist anticipates before installation.

LE RAIDISSEUR is systematically integrated under the top during the manufacturing or installation phase, and is invisible once the unit has been installed. It stiffens the top, improves its load-bearing capacity and guarantees flatness over time - an argument for durability that the kitchen designer can promote directly to the end customer.

Frequently asked questions

LE RAIDISSEUR can be installed in the width or length of table top depending on the configuration and type of deformation to be prevented.

In the width, it counteracts warping and transverse bowing - common on solid wood.

In the length, it prevents sagging under load on long spans.

Choose a length approximately 50 to 100 mmshorter than the covered dimension, so that the ends of the profile remain recessed and invisible.

Combine two stiffeners positioned in parallel or staggered to cover the entire surface.

This depends on the size to be covered and the direction of installation.

A single stiffener in the width is generally sufficient for a table top span of up to 100 cm.

In the longitudinal direction, for spans of over 160 cm or for table top in hygroscopic solid wood - oak, ash, walnut - two stiffeners laid in parallel at 1/3 and 2/3 of the width offer significantly greater strength.

The two directions can also be combined for table tops exposed to multiple stresses.

Yes, wood is a living material that swells and shrinks according to ambient humidity.

To counter this phenomenon, the oblong holes (16×8 mm) allow the screws to slide slightly in the direction of the grain - this play is deliberate.

This allows the wood's natural movement without creating excessive tension, eliminating the risk of cracking or tearing of fasteners on solid or finger-jointed wood.

Yes. On these hard materials, double the screw connection with a polymer mastic adhesive (such as Sika or MS-polymer) applied to the side of the profile in contact with table top.

This bond guarantees optimum adhesion without the risk of cracking the material.

Available in a fine-texture powder-coated finish: matte black RAL 9005.

Powder coating involves baking electrostatic polyester powder at 200°C. The result? A 60-80 micron protective coating that resists :

- Humidity: Rust-free, sheltered outdoor use (covered terrace, veranda)

- UV: No discoloration in sunlight

- Impact: Harder than simple varnish

- Corrosion: Integrated anti-corrosion protection.

It's THE professional finish par excellence for furniture that lasts.

These finishes are resistant to humidity and UV, and suitable for sheltered indoor or outdoor use.

Ultra-simple care:

  • Regular cleaning: damp cloth + mild soap (pH neutral), then dry with a dry cloth
  • White stains (limescale): Soft cloth soaked in white vinegar or cider vinegar, rinse, dry
  • Sheltered exterior: Clean 2 times a year to remove pollen and dust

Absolutely avoid:

- Abrasive products (scraping sponge, scouring powder)

- High-pressure cleaners

- Undiluted acidic products
