S4S Hardwood

S4S Hardwood Trim: Grade, Milling, and Species Standards

All s4s hardwood trim and moulding from Ekena Millwork is produced to FAS (Firsts and Seconds) grade, the highest classification in the hardwood lumber grading system. FAS material yields long, clear cuttings with minimal knots, making it the correct specification for stain grade interior trim, casing, base moulding, and architectural millwork where a finished, natural wood appearance is required.

S4S refers to surfaced four sides: all four faces of each board are milled smooth to consistent dimensions, squared, and ready for direct installation or shop fabrication. This eliminates the prep work associated with rough or S2S stock and supports consistent results across high-volume or multi-unit projects. Ekena's s4s moulding profiles are milled to repeatable tolerances, so material ordered across multiple shipments maintains dimensional consistency.

The stain grade lineup covers ten species selected to address the full range of commercial and residential specification needs: Alder, Cherry, Knotty Alder, Maple, Pine, Poplar, Red Oak, Sapele Mahogany, Walnut, and White Oak. Each species carries distinct grain character, hardness, and finish response; the breadth of the offering allows architects and specifiers to match trim material to structural wood elements, flooring, or cabinetry without sourcing from multiple suppliers.

In-Stock Inventory for Distributor and Dealer Programs

Ekena Millwork stocks all ten stain grade species plus Primed Fingerjoint Pine, maintaining ready-to-ship inventory across the full s4s hardwood trim line. For distributors managing project timelines and dealers filling contractor orders, in-stock availability eliminates the uncertainty of mill lead times and minimum run requirements that come with special order hardwood programs.

Primed Fingerjoint Pine is stocked as a paint grade complement to the stain grade line. It is appropriate for painted interior trim applications where wood grain is not a finish consideration, and it ships on the same timeline as the stain grade species.

Stain Grade Hardwood for Architectural Trim Specifications

Architects and specifiers writing interior trim specifications can source base moulding, casing, and flat s4s hardwood profiles across all ten species from a single supplier. FAS grade material meets the clear wood requirements common in finish schedule specifications, and species availability supports coordinated material selections across trim, flooring, and millwork categories within a single project.

Spec sheets and samples are available upon request. Contact the Ekena Millwork team to support a project submittal or to confirm stock availability for a specific species and profile.
