What Defines a Bridge Saw Blade
Bridge saw blades cut fixed stone slabs on stationary, track-guided saws. Fabricators specify them for granite, quartzite, marble, engineered stone, porcelain and travertine used in worktops and architectural pieces. The buying decision starts with slab, saw power, diameter, arbor, water delivery and accepted edge condition.
A professional bridge saw blade may use laser-welded or another approved segment-joining construction with a tensioned steel core. Select bond, segment height, kerf, diamond placement, core tension and run-out against the saw and slab. Zhonghuan confirms the selected build and acceptance limits on a witnessed sample cut before production.
Zhonghuan Bridge Saw Blade Spec
| Parameter | Standard Spec |
|---|---|
| Diameter range | 12-24 inch (300-600mm) |
| Segment attachment | Laser-welded, 1.5mm minimum penetration, no cold-pressed in this line |
| Segment height | 10mm standard / 12mm premium granite / 15mm hard quartzite |
| Kerf width | .118-.157 inch per SKU (3.0-4.0mm) |
| Body steel | 1075 high-carbon spring steel, HRC 38-42 |
| Body tension | Run-out under 0.1mm at full diameter — tighter than wall/floor saw blades |
| Arbor | 60/50mm pinhole or 25.4mm 1-inch — per channel |
| Steel core finish | Natural — no painted color coding |
| Diamond placement | Uniform distribution standard / ordered array (Arix-equivalent) premium option |
Substrate-Matched Configurations
| Substrate | Bond + Diamond | Benchmark Reference |
|---|---|---|
| Granite (Mohs 6-7) | Cobalt-bronze soft bond, C30-C40, US 40/50 grit | Compare named Diteq and Diamond Vantage SKUs on the target granite or quartzite |
| Quartzite (Mohs 7-8) | Soft-medium cobalt-bronze, C35-C45, US 50/60 | Match Slayer Quartzite Silent Core, Zenesis Quartzite |
| Engineered stone (quartz) | Resin-tuned specialty bond, C25-C30, US 40/50 | Match Zenesis Obsidian, Weha Puma |
| Marble (Mohs 3-4) | Medium-hard cobalt-iron, C20-C30, US 50/60 | Compare a Weha reference SKU on the target marble |
| Porcelain slab | Hard cobalt-iron-tungsten, C30-C40, US 60/80 fine | Match Helix ARIX Porcelain, Husqvarna Superlok |
Steel Core Finish — Premium Convention
Premium bridge-saw sourcing starts with the slab and the machine, not the paint colour of the steel core. We document bond, segment height, kerf, crystal arrangement, core tension, arbor and water flow by SKU. A natural finish or a coloured finish can both be used when they match the approved marking and engineering specification; the sample cut determines fit.
RFQ Checklist
- Target substrate per SKU (granite, quartzite, engineered stone, marble, porcelain slab, travertine)
- Diameter and kerf list per SKU (12″ through 24″)
- Segment height (10mm standard, 12mm premium granite, 15mm hard quartzite)
- Arbor (60/50mm pinhole European-Korean / 25.4mm 1-inch US — confirm channel)
- Diamond placement tier (uniform distribution standard / ordered array premium)
- Bond formula by substrate description, not by code letter
- Diamond grit (US 40/50 to 60/80) and concentration (C25-C45)
- Tension test per ANSI B7.1 or EN 13236 — run-out under 0.1mm at full diameter
- Laser-weld destructive cross-section per production lot
- Witness cut in target substrate (30mm polished granite or 20mm engineered stone)
- Steel core finish (natural — no painted color coding)
- Packaging: individual foam-insert box, blister card, or printed center label
