Grading Rules

Darien Millworks & Timber wrote the grading rules for antique heart pine, based on the 1922 Southern Pine Inspection Bureau grading manual. It is now the industry standard.

We have inventory in all three grades. Let us help you decide which is right for your project.

Clearest grade

Very few, small sound knots
