Green Oak Frames
Green oak is the name used for the unseasoned timber that is used to make the oak frames in new buildings.
Stains and black marking naturally occur to the green oak due to natural tannin acids in the oak reacting with the metal tools used in processing and transportation. All fixings and tools used on green oak should be of a non-ferrous type like stainless steel but more often than not this is not the case, resulting in the unsightly stains.
As you can see from the pictures shown we are able to remove these marks from oak frames, leaving them with a natural and clean appearance. The beams are then finished as desired i.e. wax, oil, shellac sealer. All of these finishes allow the beam to breathe.
