Description
This DXF template provides specifications for fabricating maximum-width 60-inch stone stair treads with traditional bullnose nosing in economical 2cm thickness. The 60-inch width creates exceptional walking surfaces and dramatic architectural presence while 2cm (0.787 inches) thickness optimizes material cost. This specification requires careful engineering and installation but delivers impressive results for budget-conscious grand staircase projects. The combination of maximum width and minimum thickness demands rigorous attention to substrate support and installation quality. When properly executed with appropriate materials and support spacing, this specification delivers cost-effective solutions for residential and light commercial applications where visual impact and generous tread dimensions are priorities. The bullnose profile maintains traditional elegance across the impressive 60-inch span.

Installation Overview
Installation of 60-inch 2cm treads requires professional expertise and meticulous support planning. Support stringers must be spaced 20-24 inches maximum on center with continuous rear bearing. Full-bed adhesive application is critical to prevent voids. Use multiple measurement points (minimum five) across the 60-inch width to verify level. Temporary mid-span shoring during cure is essential. Consider reinforcement mesh on underside. Weight approximately 65-75 lbs per tread requires two to three person handling.
CNC Cutting Notes
CNC programming for 60-inch 2cm material requires industrial equipment with extensive bed length and multiple vacuum zones. Material support across the length is critical to prevent flexing during cutting. The bullnose profile demands radius bits and significantly reduced feed rates (60% of straight cuts). Plan tool paths to maintain material rigidity throughout the cutting sequence. Execute perimeter cuts before profile operations. Back-chamfer all edges.
Material Compatibility
This 2cm template works with granite, engineered quartz, and quartzite exhibiting excellent structural properties. Engineered quartz performs best due to homogeneous strength and engineered integrity. Avoid soft materials unless laminated. Select granite with tight grain patterns and minimal veining. Orient grain perpendicular to tread depth. Materials with pronounced veining should run perpendicular to the 60-inch length to reduce breakage risk.
Where to Buy
Extra-wide 60-inch treads in 2cm thickness require specialized fabricators equipped for large-format work. Contact shops serving commercial and high-end residential markets with large-format slab capabilities. Request samples demonstrating bullnose quality across extended widths. Expect 2-3 week turnaround. Professional installation is essential for treads of this scale.
