Description
This professional-grade DXF template provides exact specifications for fabricating a 48-inch stone stair tread with an elegant beveled nosing profile. Designed for countertop fabricators and stone contractors, this template ensures consistent, code-compliant stair treads in granite, marble, quartz, or other natural and engineered stone materials. The beveled nose design offers a refined aesthetic while maintaining structural integrity and durability. At 3cm thickness (approximately 1.181 inches), this template accommodates standard stone slab dimensions and provides the necessary strength for residential and light commercial applications. The 1-inch nosing overhang creates the proper visual line and drip edge while meeting typical building code requirements for stair tread projections.

Installation Overview
Installation begins with precise measurement of the existing stair structure, ensuring level treads and proper support substrates. The stone tread should be dry-fitted before final adhesive application, checking for level across both width and depth. Use high-strength construction adhesive or mortar specifically rated for stone applications, applying a continuous bead along the back edge and support points. The beveled nosing should align flush with the riser face or as specified by local building codes. Allow adequate curing time before subjecting the tread to foot traffic, typically 24-48 hours depending on ambient conditions and adhesive specifications.
CNC Cutting Notes
Program your CNC router with appropriate tool paths for both the perimeter cut and the beveled nose profile. The bevel profile requires a specialized router bit or a two-pass operation using angled tooling. Feed rates should be reduced when cutting the profile edge to prevent chipping, typically 60-80% of straight-line cutting speeds. Use ample coolant or water flow to minimize heat buildup and dust generation. For 3cm material, ensure your vacuum hold-down system provides sufficient clamping force, particularly near the overhanging nose where material support is reduced. Back-chamfer all sharp edges to prevent chipping during handling and installation.
Material Compatibility
This template works with all standard stone materials including granite, marble, quartzite, and engineered quartz. For softer materials like marble or limestone, consider reinforcing the nosing area with epoxy resin or fiberglass mesh on the underside. Engineered quartz materials require carbide tooling and may necessitate slower feed rates due to their density. Exotic stones with heavy veining patterns should be oriented to minimize vein run-out at the nosing edge, where structural weakness could lead to breakage.
Where to Buy
Stone stair treads are typically custom-fabricated by local stone fabrication shops and countertop companies. Contact certified fabricators in your area who can source appropriate stone materials and cut to this template specification. Many fabricators can also assist with material selection, finish options (polished, honed, leathered), and professional installation services to ensure code compliance and optimal longevity.
