Solid ash panels

We buy approx 35m3 of Ash panels per 4-6 weeks.
Current factory cannot meet demand.
Must be quality A/B.
Free from knots and splits finished 25mm thick.
We have had many time wasted in past with poor service and very poor quality.
Panels need to be very good quality and the service MUST be excellent. If full truck ordered we expect full truck to be delivered.
