Description
The Dupont edge profile brings sophisticated architectural detail to single-thickness 3cm granite installations, creating the signature stepped edge that has become a hallmark of premium countertop design without requiring the complexity and expense of laminated construction. This template is precision-engineered for natural granite slabs in standard 3cm thickness, producing a 1.181-inch tall edge profile that maximizes visual impact within the constraints of single-slab fabrication. The characteristic straight step or notch of the Dupont profile creates shadow lines and dimensional interest that elevate granite installations from basic functionality to architectural statements, making it a popular choice for homeowners and designers seeking luxury aesthetics with proven material performance. Natural granite's exceptional hardness, ranging from 6-7 on the Mohs scale, makes it ideally suited for edge profiling that demands crisp, clean lines capable of withstanding years of use without degradation. This template incorporates an extended eleven-position polishing sequence specifically calibrated for granite's crystalline structure, progressing through finer grits than laminated profiles to achieve the mirror-finish gloss that distinguishes quality granite fabrication. The single-thickness construction eliminates lamination complexity while still delivering substantial visual presence through careful profile geometry that maximizes the perceived edge thickness. This approach offers cost savings compared to laminated alternatives while maintaining the Dupont aesthetic that commands premium positioning in the marketplace.

Installation Overview
Installing Dupont edge profiles on single 3cm granite slabs follows established natural stone fabrication practices with specific attention to the stepped profile geometry that creates vulnerable stress points requiring proper support. Fabrication begins with careful slab inspection to identify any natural fissures, mineral inclusions, or structural weaknesses that could compromise edge integrity during profiling or subsequent use. The CNC machining process uses the eleven-position polishing sequence optimized for granite's hardness, with particular care during the step transitions where the profile changes depth. Unlike laminated edges, single-thickness profiling must work within the 1.181-inch height constraint, making precise tool path programming essential for achieving the Dupont geometry while maintaining adequate material strength. On-site installation requires substrate support appropriate for 3cm granite weight and capable of handling the concentrated loads created by the stepped profile rather than distributed across a uniform thickness. Support brackets should be positioned every 24 inches for overhangs, with particular attention to avoiding point loads at the profile step location where reduced material thickness creates stress concentration. Professional installation practices including proper shimming, adequate substrate flatness, and appropriate adhesive coverage ensure long-term performance without cracking or failure at the profiled edge. The finished installation delivers the premium Dupont aesthetic while leveraging granite's proven durability and relatively straightforward maintenance requirements compared to more delicate natural stones.
CNC Cutting Notes
Single 3cm granite Dupont profiling requires a carefully orchestrated machining sequence that balances aggressive material removal during roughing with extended polishing to achieve the mirror finish expected in premium granite installations. The process begins with a 20mm roughing finger bit operating at 2800 RPM to establish the basic stepped profile geometry within the limited material thickness. A secondary roughing pass at 2380 RPM with fine depth increments refines the profile surfaces, removing the major tool marks that could telegraph through subsequent polishing stages. The eleven-position polishing sequence represents a more extensive progression than laminated profiles, starting with 50-grit metal bond pads at 2240 RPM to address the roughing marks and establish flat surfaces. Progression through 100, 200, 400, 800, 1500, 3000, 6000, and 8000 grit stations uses resin bond pads with gradually increasing speeds up to 3520 RPM, with the additional fine-grit positions creating the exceptional gloss that single-thickness profiles demand to compete visually with thicker laminated alternatives. The extended polishing sequence adds approximately 3-4 minutes to total machining time compared to laminated profiles, but the investment in additional polishing stages delivers superior surface quality that maximizes granite's natural luster and crystalline sparkle. The final buffing stage at 3200 RPM brings out the mirror finish characteristic of quality granite edge work. Total machining time averages 12-16 minutes per linear foot, with the extended duration reflecting both the additional polishing positions and the careful technique required to prevent chipping at the stepped transitions where material thickness reduces. Adequate coolant flow throughout the process manages heat while flushing granite particles that could scratch polished surfaces if allowed to accumulate.
Material Compatibility
This profile template is optimized for natural granite varieties across the full spectrum from light to dark colors and from subtle to dramatic figuring patterns. Performs exceptionally well with dense granites including Absolute Black, Steel Grey, Baltic Brown, and Ubatuba that can support the stepped profile geometry without risk of edge failure from natural weaknesses. Medium-density granites such as Santa Cecilia, Giallo Ornamental, Kashmir White, and Uba Tuba also machine beautifully with these parameters, delivering professional results across the most commonly specified varieties. Highly figured exotic granites with dramatic veining or color variation create stunning visual effects when the stepped profile accentuates natural movement in the stone. The Dupont step works particularly well with granites featuring directional patterns or contrasting mineral bands, as the shadow line created by the profile enhances visual drama. Not recommended for extremely coarse-grained granites where large crystal structures might fracture unpredictably during profiling, or highly fissured varieties where natural weaknesses could cause edge failure at the step transition where material thickness reduces. Works best with granites maintaining relatively consistent density and hardness throughout the slab thickness, as dramatic variation between surface and interior can complicate polishing progression and final finish quality. The extended polishing sequence in this template particularly benefits harder granite varieties where achieving maximum gloss requires the progressive refinement that additional grit positions provide.
