Description
This DXF template provides specifications for fabricating versatile 42-inch stone stair treads with traditional bullnose nosing in economical 2cm thickness. The 42-inch width represents a popular mid-range dimension that balances generous walking surface with material efficiency and fabrication practicality. At 2cm (0.787 inches) thick, this template optimizes cost-effectiveness while delivering adequate structural performance for residential applications with proper substrate support. The bullnose profile offers the timeless rounded edge that has defined quality stone stair construction for generations. The 42-inch width accommodates comfortable passage and exceeds minimum building code requirements in most jurisdictions, making it ideal for primary residential staircases, multi-family dwellings, and light commercial applications. The combination of moderate width and reduced thickness creates an economical solution without compromising aesthetic appeal or functional performance.

Installation Overview
Installation of 42-inch 2cm stone treads requires adequate support spacing to prevent flexing across the width. Support stringers or walls should be spaced no more than 20-24 inches on center with continuous bearing along the rear edge. Apply construction adhesive or thin-set mortar in full-bed fashion to eliminate voids that could allow deflection under load. The bullnose nosing should project uniformly 3/4 to 1 inch beyond the riser face across the full width. Verify level at multiple points across the 42-inch span during installation, using shims or leveling clips as needed. The moderate width makes these treads manageable for two-person installation teams while still requiring careful handling to prevent cracking or chipping.
CNC Cutting Notes
Programming for 42-inch treads requires consideration of material support across the extended width during cutting operations. Use multiple vacuum zones to secure the material uniformly, preventing flexing that could affect dimensional accuracy. The bullnose profile demands radius-cutting bits (typically 1.5 to 2-inch radius) and reduced feed rates of 60-70% compared to straight cuts to maintain edge quality. For 2cm material, ensure adequate hold-down pressure particularly near the nosing overhang where material support decreases. Execute perimeter cuts before profile operations to maintain material rigidity during the critical bullnose shaping. Back-chamfer edges to prevent chipping during handling and installation.
Material Compatibility
This 2cm template works well with granite, engineered quartz, and quartzite materials that provide good structural properties at reduced thickness. Engineered quartz is particularly well-suited due to its homogeneous strength characteristics. Natural granite should exhibit tight grain patterns without pronounced veining that could create stress points across the 42-inch width. Avoid soft materials like marble or limestone in 2cm thickness for this width unless laminated for reinforcement. When selecting materials, orient grain patterns perpendicular to the tread depth rather than parallel to the 42-inch length to minimize breakage risk along natural cleavage planes.
Where to Buy
Stone stair treads in 42-inch width with bullnose profiles are widely available through stone fabrication shops and countertop fabricators. This popular dimension means most fabricators have appropriate tooling and templates ready for efficient production. Contact local stone yards for material selection and fabrication quotes. Expect turnaround times of 1-2 weeks for custom cutting. Many suppliers maintain inventory of common granite and quartz colors, allowing relatively quick material selection and fabrication. Request samples showing bullnose radius and finish quality before committing to full orders.
