High quality A/B grade Ash Veneered MDF panel measuring 600mm x 400mm. Ideal for structural projects requiring a high quality appearance and finish on both the topside and panelling. Suitable for laser cutting.
This MDF panel is veneered on both faces of the sheet: A grade veneer on the front and B grade on the reverse. Please note: As wood is a natural product, there is often a crook or bow to the sheet. The natural twist might be in excess of 10mm (see below - Tolerances and Caution).
A wood veneer is not like an artificial surface such as melamine or a laminate. It is cut from the log and therefore has its own unique grain, texture, and colour.
A Grade Veneer is a very high quality grading (typically the best you will see). The surface of the material will be consistent in appearance with no large variations in colour. Small pin knots are allowed and these would typically be only a few mm in diameter. This grade veneer is on the topside of this MDF sheet.
The B Grade Veneer underside shows the natural look of the veneer. There will be changes in colour that show the grain pattern. Sound, smooth knots are allowed and these will typically be under 15mm to 35mm in diameter (depending on the countries grading rules). The surface should normally be free from open knots and plugs. The material should be suitable for paint / stain or a lacquered finish.
There are two different cuts that can be used in veneer production:
- 'Quarter Cut' are cut at 90 degrees, producing the effect of a straight grain.
- 'Crown Cut' are sliced through the log, producing 'Crowns' and adding more character to the finish (as used on this product).
This product conforms to E1 (low) formaldehyde levels and is often described as 'Laser Grade' MDF but there is no official classification for this. We believe that E1 conforming MDF is the safest and best MDF for using in a laser cutter.

The manufacturing tolerance for the thickness of veneered MDF sheets include the tolerance for both the MDF and the veneer. The total combined thickness of both the MDF and the veneer could be as little as 3.35mm and as much as 4.65mm. The veneer on each face could be as thin as 0.25mm and as thick as 0.75mm.
- As wood is a natural product there is often a bow or crook to the MDF, and in some cases a twist. We have measured in excess of 10mm rise between the flat centre of the MDF and the corner. These twists are completely normal If you are using this product on a laser cutter; these sheets should be strapped/taped to the laser bed before cutting.
- On all Plywood, MDF and Perspex Sheet Orders (excluding A4 size) there is a flat delivery charge of £6.50 per order in the U.K. (£18.00 for remote locations).
The ash is an A grade on one side, and B grade on the underside. The A side does appear to have a slight shine to it as it has a better sanded finish. For a full description of the different grades please view our wood grading blog, https://www.kitronik.co.uk/blog/plywood-grading-resource/. We don’t do a product in 4mm which has an A grade on both sides.Posted byon Thursday, 14 April 2016
