Description
This DXF template provides specifications for fabricating versatile 42-inch stone stair treads with traditional bullnose nosing in premium 3cm thickness. The 42-inch width offers an ideal balance between generous walking surface and material efficiency, while 3cm (1.181 inches) thickness delivers superior structural performance and durability. This combination serves as the workhorse specification for quality residential and light commercial staircases. The bullnose profile provides timeless elegance while the substantial thickness ensures longevity. The 42-inch width accommodates comfortable two-person passage and exceeds minimum code requirements in most jurisdictions, making it suitable for primary residential staircases and commercial applications where durability matters.

Installation Overview
Installation of 42-inch 3cm treads follows professional standards with the advantage of working with substantial material thickness. Support stringers or walls should be spaced 24-30 inches on center with continuous rear edge support. Apply construction adhesive or mortar in full-bed fashion. The bullnose should project uniformly 3/4 to 1 inch beyond the riser face. The 3cm thickness (weighing 60-70 lbs per tread) requires two-person handling but provides excellent stability during installation and tolerance for minor substrate irregularities.
CNC Cutting Notes
CNC operations for 42-inch 3cm treads utilize industrial equipment with robust hold-down systems. The material thickness allows pronounced bullnose radii (2 to 2.5 inches) for elegant profiles. Use appropriately sized diamond tooling with adequate depth capability. Feed rates for bullnose profiling should be 65-75% of straight-line speeds. Program multiple passes for optimal edge quality. Water cooling is essential for heat management in substantial material removal operations.
Material Compatibility
This template accommodates all premium stone materials including granite, marble, quartzite, and engineered quartz. The 3cm thickness particularly suits softer materials like marble that benefit from added mass. Exotic granites display well in this format. Engineered quartz provides maximum commercial durability. The substantial thickness supports reliable fabrication across all material types.
Where to Buy
42-inch bullnose treads in 3cm thickness are standard offerings at most stone fabrication shops. This popular specification means readily available materials and tooling. Contact local fabricators for quotes; expect 1-2 week turnaround. Many offer material selection assistance and professional installation services.
