Description
This engineered DXF template addresses the popular mid-range width of 42 inches using 2cm+2cm laminated construction with the classic bullnose nosing profile. The 42-inch dimension bridges the gap between compact and wide treads, providing generous walking surface while maintaining reasonable material costs and fabrication complexity. Laminated construction delivers the structural benefits of 1.575-inch thickness while utilizing economical 2cm slabs. The bullnose profile combined with laminated construction creates an ideal solution for residential and light commercial staircases where both traditional aesthetics and cost-efficiency matter. This width accommodates comfortable two-person passage and meets or exceeds most building code requirements for stair width. The lamination process allows fabricators to select optimal slab sections for both the walking surface and the nosing profile, maximizing material utilization while ensuring quality appearance on all visible surfaces.

Installation Overview
Installation of 42-inch laminated treads requires attention to proper support spacing to prevent mid-span flexing. Support stringers or walls should be spaced 20-26 inches on center with continuous bearing along the rear edge. Apply construction adhesive or thin-set mortar in full-bed fashion to ensure complete contact with the substrate, eliminating voids that could stress the laminated bond. The bullnose nosing should project uniformly 3/4 to 1 inch beyond the riser face across the full width. Use at least three measurement points across the 42-inch span to verify level during installation. Allow adequate cure time (24-48 hours minimum) before subjecting the treads to traffic loads, particularly important for laminated construction where both the tread-to-substrate bond and the internal lamination bond must fully cure.
CNC Cutting Notes
CNC operations for laminated 42-inch treads demand precision to maintain material integrity across the width. Ensure complete cure of the lamination (48-72 hours preferred) before cutting to prevent delamination. Use multiple vacuum zones across the 42-inch length to secure the material uniformly during cutting operations. The bullnose profile requires radius bits appropriate for the laminated thickness; program tool paths to cut cleanly through both layers without exposing the bond line. Feed rates should be conservative, approximately 70-80% of solid stone rates, with particular attention to preventing heat buildup at the cut line that could stress the adhesive bond. Plan perimeter cuts before profile operations to maintain material stability during the critical bullnose shaping.
Material Compatibility
Laminated construction at 42-inch width works excellently with granite, engineered quartz, and quartzite materials that bond reliably with professional stone adhesives. Careful material selection and color matching creates nearly invisible bond lines when viewed on the finished tread. Engineered quartz requires manufacturer-approved adhesives and may void warranty if improper bonding agents are used. Natural granite and marble should be laminated using UV-resistant, color-tinted adhesives matched to the stone color. The 42-inch width allows book-matching of slabs for dramatic visual effects, with the laminated construction providing the structural support needed for such wide single-piece treads.
Where to Buy
Laminated stone stair treads in 42-inch width require fabricators equipped with lamination capabilities including vacuum presses or adequate clamping systems to ensure complete adhesive contact across the width. Contact stone fabrication shops specializing in architectural work or custom residential projects, as standard countertop shops may not offer lamination services. Professional fabricators can guide material selection, demonstrate lamination quality through samples, and often provide installation services or professional installer referrals. Expect lead times of 2-3 weeks for laminated tread fabrication to allow for proper material selection, lamination cure, and CNC fabrication.
