Description
This DXF template provides specifications for fabricating wide 48-inch stone stair treads with traditional bullnose nosing in economical 2cm thickness. The 48-inch width creates generous walking surfaces and visual prominence while 2cm (0.787 inches) thickness optimizes material cost. This specification suits residential and light commercial applications where proper substrate support can be provided. The combination of substantial width and reduced thickness requires careful installation planning but delivers cost-effective results for budget-conscious projects. The bullnose profile maintains traditional elegance. Proper support spacing and quality installation practices ensure reliable long-term performance despite the economical material thickness.

Installation Overview
Installation of 48-inch 2cm treads requires proper support spacing to prevent mid-span flexing. Stringers or walls must be spaced 20-24 inches maximum on center with continuous rear support. Full-bed adhesive application is essential to eliminate voids. Use at least four measurement points across the 48-inch width to verify level. Consider temporary mid-span shoring during cure. Weight approximately 45-52 lbs per tread requires two-person handling.
CNC Cutting Notes
CNC programming for 48-inch 2cm material requires careful attention to material support across the width. Use multiple vacuum zones to prevent flexing during cutting. The bullnose profile demands radius bits (1.5-2 inch) and reduced feed rates (60-70% of straight cuts). Ensure adequate hold-down near nosing overhang. Execute perimeter cuts before profile operations to maintain rigidity. Back-chamfer edges to prevent chipping.
Material Compatibility
This 2cm template works with granite, engineered quartz, and quartzite exhibiting good structural properties. Engineered quartz performs best due to homogeneous strength. Avoid soft materials unless laminated. Select granite with tight grain patterns. Orient grain perpendicular to tread depth rather than parallel to the 48-inch length to minimize breakage risk.
Where to Buy
Wide 48-inch treads in 2cm thickness are available through fabricators equipped for large-format work. Contact shops serving commercial projects as they typically handle larger slabs. Request samples showing bullnose quality. Expect 1-2 week turnaround for fabrication.
