Description
This professional DXF template delivers complete fabrication specifications for a 42-inch wide stone stair tread in 2cm thickness featuring integrated anti-slip safety grooves. The extended 42-inch width accommodates wider stair applications while the 2cm single-piece construction provides a lighter-weight solution compared to thicker alternatives. This template serves specialized applications where both extended width and weight reduction are beneficial, such as historic building renovations, weight-sensitive structures, or installations where reduced mass is advantageous. Wide-format stone stair treads create impressive architectural features while the 2cm thickness (approximately 0.787 inches) minimizes structural loads. The 42-inch width provides generous foot placement area suitable for grand staircases, commercial entries, or residential applications requiring broader treads. The anti-slip grooved design enhances safety across the full width, critical for preventing slips on wider walking surfaces. The 12-inch depth meets building code requirements while the 1-inch nosing overhang maintains standard stair geometry. Fabricators receive comprehensive specifications including anti-slip groove placement optimized for the wider format, nosing profile geometry accounting for material thickness limitations, reference lines, and CNC-ready toolpaths. The template supports granite, marble, quartzite, and engineered quartz materials, compatible with all major CNC systems and CAD software.

Installation Overview
Installation of 42-inch wide 2cm treads requires exceptional attention to substrate support. The combination of extended width and thinner material demands continuous, void-free support across the entire 42-inch by 12-inch footprint. Any voids or gaps in adhesive coverage can create stress concentrations leading to fractures. Ensure stair substrate is perfectly level, structurally sound, and rated for the tread span. Apply high-quality construction adhesive or thin-set mortar with meticulous attention to complete coverage. Position requires two-person handling despite lighter weight compared to thicker materials. Maintain consistent 1-inch nosing overhang across the full 42-inch width. Verify level in both directions and adjust carefully. The thinner material offers no tolerance for installation irregularities. Anti-slip grooves should face the leading edge. Allow extended cure time - minimum 48 hours before light foot traffic, 72 hours preferred. The 2cm thickness in 42-inch width is best suited for light residential traffic; not recommended for heavy commercial applications without engineering review.
CNC Cutting Notes
Program anti-slip grooves on the top surface with conservative depths - maximum 1/8 inch for 2cm material to prevent weakening. Grooves typically 1/4 to 3/8 inch wide, positioned 1 to 2 inches from nosing edge. Consider multiple groove rows across the wider 42-inch format for enhanced slip resistance. Use sharp diamond tooling for natural stone, carbide for engineered quartz, with conservative feed rates to prevent chipping on thinner material. The 42-inch length requires adequate CNC bed size or creative fixturing solutions. Nosing profile must account for limited material thickness - simple bullnose, small bevel, or eased edge profiles work best. Complex profiles not recommended for 2cm material. Finish all exposed edges carefully. The combination of extended width and thin profile demands careful handling during all fabrication stages. Support material continuously during cutting and finishing operations. Inspect completed treads thoroughly for micro-fractures before installation, particularly in natural stone materials.
Material Compatibility
Best suited for engineered quartz materials that provide uniform density and engineered strength characteristics across the extended 42-inch span. Quartz manufacturers specifically engineer 2cm material for strength, making it more suitable than natural stone for this demanding application. Dense granite varieties can work but require careful selection - absolute black granite and other very dense, consistent materials only. Avoid granites with natural fissures, heavy veining, or structural variations. Marble is generally not recommended for 42-inch wide 2cm stair treads due to lower hardness and structural limitations. Quartzite can work if exceptionally dense and consistent, but verify thickness uniformity across the full 42-inch length. The 42-inch width requires jumbo-sized slabs - verify material availability in adequate dimensions. All materials must be free from structural weaknesses and meet slip-resistance requirements.
Where to Buy
This professional DXF template is available as free download from Slabwise. Engineered quartz materials in 2cm thickness with jumbo dimensions suitable for 42-inch wide treads can be sourced from Caesarstone, Cambria, Silestone, HanStone, and other premium manufacturers offering larger format slabs. Natural stone slabs in 2cm thickness and adequate dimensions are available through select wholesale distributors carrying jumbo-sized granite and quartzite slabs. Installation adhesives specifically formulated for large-format thin stone are available from stone fabrication suppliers. Proper adhesive selection is critical for successful 42-inch wide 2cm installations.
