For fabrication shops, quartz and granite represent the bulk of your work - typically 60-70% of jobs combined.
Which material is most profitable for fabricators?
Profitability depends on your markup structure, waste rate, and labor efficiency. General guidance:
Highest margin per job: Exotic natural stone (rare granites, book-matched marble). These command premium pricing and customers expect to pay more.
Highest margin per labor hour: Quartz. It's consistent, predictable to cut, produces uniform edges, and has lower waste rates because there's no vein matching to worry about.
Lowest margin: Basic builder-grade granite. High competition, price-sensitive buyers, and thin markups. But it's high volume.
What's the difference between quartz and quartzite?
This causes more customer confusion than any other question in the countertop industry:
Quartz - Engineered (man-made). About 93% ground natural quartz crystals bound with 7% polymer resin. Consistent color and pattern. Brands include Caesarstone, Cambria, Silestone, and MSI.
Quartzite - Natural stone. Quarried from the earth. Each slab is unique. Typically white/gray with dramatic veining. Examples: Taj Mahal, White Macaubas, Fantasy Brown.
| Attribute | Quartz (Engineered) | Quartzite (Natural) |
|---|---|---|
| Origin | Manufactured | Quarried |
| Pattern consistency | High (batch-to-batch) | Each slab unique |
| Hardness (Mohs scale) | 7 | 7-8 |
| Heat resistance | Moderate (resin can scorch) | High |
| Stain resistance | High (non-porous) | Moderate (needs sealing) |
| UV resistance | Low (can fade in sunlight) | High |
| Price range | $50-$120/sqft | $70-$150/sqft |
For fabricators, quartzite is harder on blades and requires more skill to fabricate (especially edge finishing), but commands higher prices.
Material-Specific Fabrication Questions
Does material type affect slab nesting?
Yes, in several ways:
Vein direction matters for marble, quartzite, and many granites. The nesting algorithm must respect grain orientation to ensure visual consistency across seamed pieces. This constraint reduces the algorithm's flexibility, which can slightly increase waste compared to vein-free materials.
Quartz is easiest to nest because most patterns are uniform. Pieces can be rotated freely, giving the algorithm maximum flexibility.
Material hardness doesn't directly affect nesting layout but affects cut time and blade wear, which factor into production scheduling.
SlabWise's nesting algorithm accounts for material-specific constraints automatically when you specify the material type.
How does material type affect fabrication time?
Approximate fabrication times per kitchen (45 sqft average):
| Material | CNC Cut Time | Edge Finishing | Total Fab Time |
|---|---|---|---|
| Quartz (3cm) | 25-35 min | 20-30 min | 1.5-2.5 hours |
| Granite (3cm) | 20-30 min | 15-25 min | 1.5-2 hours |
| Marble (3cm) | 25-35 min | 25-40 min | 2-3 hours |
| Quartzite (3cm) | 30-45 min | 30-45 min | 2.5-3.5 hours |
| Porcelain (1.2cm) | 20-30 min | 20-35 min | 1.5-2.5 hours |
Quartzite is the most labor-intensive due to its hardness. Porcelain requires different tooling (diamond-specific) and careful handling due to its thinness.
Which materials have the highest waste rates?
Waste rates depend on both material properties and job geometry, but some materials trend higher:
- Marble and quartzite: 15-25% waste (vein matching constraints, defect avoidance)
- Granite: 12-20% waste (some vein matching, fewer defects)
- Quartz: 10-15% waste (no vein constraints, consistent quality)
- Porcelain: 12-18% waste (large format but brittle, breakage adds to waste)
These are averages for manual nesting. SlabWise's nesting optimization reduces waste across all material types, with the biggest absolute savings on materials with naturally higher waste rates.
What blade types do different materials require?
| Material | Blade Type | Typical Blade Life | Notes |
|---|---|---|---|
| Quartz | Standard diamond | 150-200 cuts | Resin can gum blades; use adequate water |
| Granite | Standard diamond | 200-300 cuts | Most forgiving material to cut |
| Marble | Fine diamond | 100-150 cuts | Prone to chipping; slower feed rate |
| Quartzite | Premium diamond | 80-120 cuts | Very abrasive; highest blade cost |
| Porcelain | Porcelain-specific diamond | 100-150 cuts | Requires specialized tooling |
Blade cost is a real factor in material profitability. Quartzite jobs consume blades 2-3x faster than granite.
Customer-Facing Material Questions
What should fabricators tell customers about material care?
Each material has different care requirements. Providing clear guidance after installation reduces warranty claims and keeps customers happy:
Quartz: Wipe with mild soap and water. Avoid abrasive cleaners. Don't place hot pans directly on the surface (thermal shock can crack the resin). Not recommended for outdoor use (UV exposure causes fading).
Granite: Clean with stone-specific cleaner or mild soap. Reseal annually (or as recommended by the slab manufacturer). Heat-resistant but use trivets for very hot pots. Acidic substances (lemon juice, vinegar) can etch unsealed surfaces.
Marble: The highest-maintenance option. Seal every 6-12 months. Blot spills immediately - especially acids (wine, citrus, tomato). Use cutting boards always. Expect patina and character to develop over time. Some homeowners love this; others don't. Set expectations upfront.
Quartzite: Similar care to granite. Seal annually. Good heat resistance. More stain-resistant than marble but still requires sealing for porous varieties.
Porcelain: Very low maintenance. Resistant to heat, stains, and UV. Clean with any household cleaner. Essentially maintenance-free.
Which material is best for outdoor kitchens?
Granite and porcelain are the top choices for outdoor installations:
- Porcelain - UV-resistant, freeze-thaw rated, won't fade or stain. The best overall outdoor performer.
- Granite - Handles weather well if sealed properly. Wide color selection. Avoid dark colors in full sun (they absorb heat).
- Quartzite - Good UV resistance but needs sealing to handle outdoor moisture.
- Quartz - Not recommended outdoors. UV exposure causes color fading and can damage the resin binder.
- Marble - Not recommended outdoors. Too porous and susceptible to weathering.
What are the most popular colors and patterns right now?
In 2026, the trend continues toward white and gray tones that mimic the look of natural marble:
- White marble-look quartz (Calacatta patterns)
- White and gray granites (Colonial White, White Ice)
- Warm white quartzite (Taj Mahal, White Macaubas)
- Concrete-look quartz (gray tones)
- Dark dramatic stones (Cosmic Black granite, Nero Marquina marble) - smaller but growing
For fabricators, this means your quartz inventory should lean heavily toward white marble-look patterns, which consistently sell first.
Inventory and Pricing
How should fabricators price different materials?
Most shops use a tiered pricing structure:
| Tier | Materials | Typical Installed Price | Markup Over Cost |
|---|---|---|---|
| Group 1 (Budget) | Basic granite, builder quartz | $40-$55/sqft | 40-60% |
| Group 2 (Mid-Range) | Premium granite, mid-tier quartz | $55-$80/sqft | 50-70% |
| Group 3 (Premium) | Marble, quartzite, premium quartz | $80-$120/sqft | 60-80% |
| Group 4 (Exotic) | Rare natural stone, book-matched | $120-$200+/sqft | 70-100%+ |
SlabWise's Quick Quote pulls pricing from your actual inventory costs and applies your configured markup per material group, so every quote reflects real numbers.
How many material types should a shop stock?
For a small to mid-size shop:
- 3-5 quartz colors (whites, grays, one trend color)
- 3-5 granite colors (white, black, brown/gold, one exotic)
- 1-2 marble options (Carrara, Calacatta if demand supports it)
- Quartzite by special order (or 1-2 slabs if you see regular demand)
- Porcelain by special order
Total: 10-15 colors covering 90% of customer requests. Stock what sells; special-order the rest.
Health and Safety
What are the silica exposure risks with different materials?
This is critical. Fabricating stone creates respirable crystalline silica dust, which causes silicosis - a serious and irreversible lung disease.
| Material | Silica Content | Exposure Risk |
|---|---|---|
| Quartzite | 80-99% | Very high |
| Granite | 25-60% | High |
| Engineered quartz | Up to 93% | Very high |
| Marble | Very low (<1%) | Lower |
| Porcelain | Varies (20-50%) | Moderate to high |
OSHA's permissible exposure limit (PEL) for respirable crystalline silica is 50 micrograms per cubic meter over an 8-hour shift. Wet cutting, dust collection systems, proper PPE (N95 or P100 respirators), and regular air monitoring are mandatory for worker safety.
See our Silicosis Safety FAQ for detailed safety guidance.
Frequently Asked Questions
What is the most durable countertop material?
Quartzite and porcelain are the hardest and most scratch-resistant. Quartz is extremely durable for indoor use. Granite is durable but softer than quartzite. Marble is the most prone to scratching and etching.
Can you repair a chipped countertop?
Small chips in granite and quartz can often be repaired with color-matched epoxy. Marble repairs are trickier due to vein patterns. Porcelain chips are difficult to repair invisibly. Large damage typically requires section replacement.
How thick should countertops be?
Standard residential thickness is 3cm (1.25 inches). Some materials are available in 2cm (with plywood buildup underneath) and 1.2cm (porcelain). Thicker profiles look more substantial and are structurally stronger.
Do all natural stones need to be sealed?
Most do. Granite, quartzite, and marble should be sealed upon installation and resealed periodically (every 6-24 months depending on the stone). The exception is some very dense granites that pass a water absorption test.
Which material is best for a busy kitchen with kids?
Quartz. It's non-porous (no sealing needed), extremely stain-resistant, and handles the abuse of a busy family kitchen better than any natural stone.
Is marble a bad choice for kitchen countertops?
Not bad - just demanding. Marble etches from acidic foods and stains more easily than quartz or granite. Homeowners who accept the patina and treat it as character do well with marble. Those who want a pristine surface should choose quartz or quartzite instead.
What's the most eco-friendly countertop option?
Locally quarried natural stone has a smaller carbon footprint than imported materials or manufactured quartz. Porcelain is clay-based and recyclable. Some quartz brands offer products with recycled content. There's no single "greenest" option - it depends on sourcing and transportation distances.
