Description
This engineered DXF template is optimized for fabricating compact 36-inch stone stair treads using 2cm+2cm laminated construction with a classic bullnose nosing profile. The laminated approach bonds two 2cm stone layers to create a robust 1.575-inch thick tread that combines the economy of 2cm slabs with enhanced structural performance. The bullnose edge provides a timeless, elegantly rounded profile that has been the standard in stone stair construction for generations. The 36-inch width serves narrow staircases, secondary stairs, basement access, and space-constrained applications where compact dimensions are necessary. Laminated construction at this width offers fabricators flexibility in material selection and inventory management while delivering strength characteristics that often exceed solid 3cm stone. The bullnose profile is particularly well-suited to traditional and transitional design aesthetics, offering a softer, more approachable appearance compared to angular beveled edges.

Installation Overview
Installing laminated stone treads follows standard stone installation protocols with particular attention to the laminated structure. Ensure the substrate is level and provides continuous support along the rear edge and at intervals no greater than 18-24 inches across the 36-inch width. Apply construction adhesive or thin-set mortar in a full-spread method to eliminate voids that could stress the laminated bond. The bullnose edge should project uniformly, typically 3/4 to 1 inch beyond the riser face per building code requirements. Verify that the rounded profile does not interfere with riser installation. Allow full adhesive cure (24-48 hours) before subjecting treads to traffic, as premature loading can stress the installation bond.
CNC Cutting Notes
When fabricating laminated treads, the CNC cutting process must account for the bonded dual-layer structure. Ensure the lamination has fully cured (minimum 24 hours, preferably 48-72 hours) before CNC operations to prevent delamination during cutting. The bullnose profile requires specialized router bits designed for radius cutting, typically 1.5 to 2-inch radius depending on design specifications. Program tool paths to cut smoothly through both layers without exposing the bond line at the finished edge. Use adequate water cooling to manage heat that could stress the adhesive bond. Feed rates for laminated material should be conservative, approximately 70-80% of rates used for solid stone to accommodate the internal bond layer.
Material Compatibility
Laminated construction works exceptionally well with granite, engineered quartz, and quartzite, which bond reliably with epoxy and polyester stone adhesives. Match slab colors and patterns carefully during material selection to create invisible bond lines. Engineered quartz requires manufacturer-approved adhesives and bonding procedures to maintain warranty coverage. For natural materials like granite and marble, use UV-resistant, color-matched adhesives to prevent visible seams. Avoid laminating materials with significantly different hardness levels, as differential wear could eventually reveal the bond line on the bullnose profile. The rounded nosing naturally conceals the lamination seam better than sharp-edged profiles.
Where to Buy
Laminated stone stair treads require fabrication by stone shops equipped with lamination capabilities including vacuum presses or adequate clamping systems. Not all fabricators offer lamination services, so specifically seek shops advertising architectural stone work or those serving custom residential projects. The 36-inch dimension is relatively common, making material sourcing easier than wider treads. Professional fabricators can advise on material selection, recommend appropriate stone choices for your traffic levels, and often provide installation services or referrals to experienced installers familiar with laminated stone products.
