UltraStock MDF board panels are medium density fiberboard sheets that provide a consistent core for woodworking and interior projects where a smooth, uniform surface is important. The 5/8 inch thickness supports applications needing a sturdy panel while still allowing clean machining, so installers can route, groove, or profile edges without dealing with voids often found in other sheet goods. The 49 x 145 inch size covers large spans in a single sheet, which reduces joint lines across wider casework or wall panels and supports layouts that benefit from fewer seams. Because these panels belong to the MDF product class, they offer a dense, stable substrate that responds predictably under saws and routers, helping keep cuts straight and repeatable on the job. Being part of the board panel products category aligns these sheets with typical cabinet, fixture, and millwork workflows where flatness and consistent thickness matter for fitting adjacent parts.
This UltraStock, 5/8 inch thickness panel gives a substantial core that performs well where a mid-range thickness is needed for shelving, partitions, or cabinet components. The 49 x 145 inch dimensions support layouts that use extra-long pieces, which can help minimize seams in tall installations or wide built-ins. As a standard core UltraStock panel, the internal structure is designed for consistent machining, so cuts and edge treatments respond predictably along the full sheet. Being MDF in sheet stock form means it works smoothly with table saws, panel saws, and CNC equipment sized for these dimensions, supporting both shop and on-site fabrication where predictable panel behavior is valuable for tight-fitting assemblies.
The Georgia-Pacific UltraStock MDF board panels are suited to projects needing a flat, consistent substrate for finishing. The ability to be painted with excellent results supports use in interior trim, cabinet faces, and wall panels where a uniform painted surface is important. Because the panels can be printed, they also align with fixture work or display elements that rely on clear graphics laid over a dimensionally stable sheet. The option to stain the surface lets shops produce components that visually coordinate with wood-toned surroundings, which is helpful when matching casework or built-ins to existing interiors. Veneer capability means these sheets serve as a dependable backing for higher-value face veneers, so decorative species can be applied over a core that resists telegraphing irregularities. Lamination readiness further extends their role in commercial or residential work where durable laminated faces over a strong core are needed across large areas.
The 5/8 inch thickness of this MDF, 5/8X49X145 panel offers enough depth for edge profiles and joinery while still keeping sheet weight manageable across cutting and handling steps. The 49 x 145 inch size allows fabricators to nest multiple parts in a single sheet, which can improve material yield and keep panel joints away from high-visibility areas. Machined edges that can be finished smoothly and evenly reduce the touch-up work after routing or sawing, which benefits production runs where repeatable, clean edges support faster assembly. The standard core UltraStock construction contributes to uniform cutting resistance, so tooling can be set for consistent feed and finish across the panel. Being part of the MDF, sheet stock category helps integrate this product into workflows that depend on predictable sheet behavior for accurate sizing, laminating, or veneering operations.
The panel is specified as MDF, 5/8X49X145, so it has a 5/8 inch thickness with a sheet size of 49 inches by 145 inches, supporting large components or fewer seams.
The panels can be painted with excellent results, providing a smooth, consistent surface that supports uniform color and finish across cabinet parts, trim, or interior panels.
The panels can be veneered, giving decorative wood faces a stable, flat substrate so finished panels stay even and visually consistent over time.
Machined edges can be finished smoothly and evenly, supporting clean joints and profiles and helping reduce sanding and edge preparation during fabrication.
The panels can be laminated, providing a dense, uniform core that supports strong adhesion and a flat finished surface for high-pressure or similar laminates.
The panel is an UltraStock MDF product from Georgia-Pacific, aligning it with a recognized MDF brand for sheet stock used in woodworking and interior projects.
The UltraStock, 5/8 inch thickness, 49 x 145 MDF sheet gives you a standard core panel that accepts paint, print, stain, veneer, and laminate with excellent results, supporting a wide range of interior projects. Its MDF construction and smooth, machinable edges help keep fabrication straightforward when routing, sawing, or profiling components from a single large sheet. For work that benefits from a flat, consistent substrate across wide spans, this Georgia-Pacific UltraStock panel offers a practical, predictable base for your next set of cabinets, fixtures, or wall elements.
