Rough Lumber
Mason’s Mill & Lumber Co. stocks over 1,000,000 board feet of rough lumber — rough sawn and rough cut hardwoods and softwoods in thicknesses from 4/4 to 16/4. Every board is sourced from the industry’s top domestic and import sawmills and graded to the highest available standard, from FAS and Select to character-grade stock with visible mineral streaks and knots. If a species or size isn’t sitting on our racks in Houston, our supply network can usually source it fast.

This catalog covers the full range of rough lumber for interior and exterior work — furniture, cabinetry, architectural millwork, decking, siding, and structural applications — including Kebony®, thermally modified and FSC®-certified options like Accoya® and Thermory for projects that need 25+ years of durability without chemical treatment.

Iron Woods® Vanish™ Rainscreen Siding System Clips & Screws
The Iron Woods® Vanish™ System creates irresistible beauty in the art of both commercial and residential building envelope design and construction. Traditional horizontal rain screen siding has long been recommended for improved air flow allowing air to move vertically behind the siding and moisture to evaporate which significantly improves the service life of a building envelope and coating performance. The Vanish™ Rainscreen System represents a significant leap forward in rain screen design and application. The Vanish™ system also adjusts naturally to changes in humidity throughout seasonal and climatic cycles eliminating stress at the point of connection.
The unique Vanish™ Rain Screen Clips eliminate the appearance of fasteners from the building aesthetic which represents a significant improvement over traditional “on batten/face fastened” rain screen applications. The Iron Woods® Vanish™ Rainscreen System completely eliminates the need for face fastening providing a clean and appealing aesthetic appearance. The unique clip system also eliminates the possibility of moisture holding while allowing both vertical and horizontal air flow to facilitate the dispensation of moisture from behind the wood.

Grading Standards:
Every board in our inventory is graded before it reaches our racks, so you know what you’re getting before you order a sample:
FAS (First and Seconds): the highest hardwood grade — largely clear faces, minimal defects.
Select: slightly more character than FAS, still highly usable clear-face yield.
Character grade: natural mineral streaks, sound knots, and heart/sap color variation for a rustic, one-of-a-kind look..
We source exclusively from the industry’s top domestic and import sawmills, so grading is consistent from board to board — critical when you’re matching stock across a large order.
Rough Lumber for Interior and Exterior Applications

Interior: furniture, cabinetry, architectural millwork, flooring substrate, paneling, and custom moulding stock (see our 8,000+ moulding profiles)

Structural & specialty: timber-frame beams, mantels, and reclaimed/antique stock for restoration work
Frequently Asked Questions
Rough lumber hasn't been planed — it retains full nominal thickness and visible saw marks. S2S (surfaced two sides) and S4S (surfaced four sides) lumber has been milled smooth and is ready to build with, at a slightly reduced final thickness and a higher price per board foot.
Standard nominal thicknesses run 4/4 (1"), 5/4 (1‑1/4"), 6/4 (1‑1/2"), and 8/4 (2"), up to 16/4 (4") for heavy timbers. Mason's Mill stocks the full range across our hardwood and softwood species.
