Typical Applications
Where GBW panels deliver the best value: dry indoor and sheltered duties such as partitions, display racks, decorative screens and cage interiors. For outdoor or high-humidity exposure, upgrade to our galvanized-after-welded (GAW) panels.
- Indoor partition
- display rack
- decorative panel
Metallurgical Composition & Alloy Ratio Analysis
Low-Carbon Steel Wire & Zinc Coating Control
This GBW panel family is resistance-welded from Q195 / SAE 1008 low-carbon steel wire that is electro-galvanized before welding. Zinc coating thickness is verified bundle by bundle with a magnetic gauge, and readings are logged in the pre-shipment inspection report so you can audit actual coating values instead of relying on nominal claims.
All batches are tested via handheld PM-I spectrometer before Tianjin Port export, guaranteeing material compliance.
Service Limits & Weld Integrity
- Zinc Coating Verification：Electro-galvanized zinc layer measured by magnetic gauge on every wire bundle, with actual readings recorded per ASTM A641 / EN 10244-2 practice and available in your pre-shipment report.
- Weld Point Corrosion Note：Welding burns off zinc at each intersection, so weld points are where rust can start first. We limit burn-off with controlled welding current and recommend indoor or sheltered use; zinc-rich touch-up spray is available for cut edges.
- Weld Shear Strength：Random intersections from every batch are shear-tested per ASTM A185/A497 to confirm each weld holds its rated load before packing.
- Corrosion Class vs GAW：Electro-galvanized GBW is the economical choice for dry indoor service. For outdoor, coastal or long maintenance-free cycles, choose our hot-dip galvanized-after-welded panels (SPU-WM-011), whose heavier zinc layer also seals the weld points.
Dimensional Tolerance Reference for 2-8 Mesh GBW Panels
Every specification in this family (2, 4 and 8 mesh) falls within the 1-50 mesh tolerance band shown below: wire diameter held within +/-0.013 mm and aperture within +/-3% of nominal. Weld intersections are additionally shear-tested per ASTM A185, and actual measured values can be listed in your pre-shipment inspection report.
| Nominal Mesh Range | Max Wire Dia. Tolerance | Max Aperture Size Tolerance | Warp Tilt Deviation |
|---|---|---|---|
| 1 to 50 Mesh | ± 0.013 mm (0.0005 inch) | ± 3% of nominal aperture | Tilt deviation ≤ 2° |
| 51 to 200 Mesh | ± 0.008 mm (0.0003 inch) | ± 5% of nominal aperture | Tilt deviation ≤ 1.5° |
| 201 to 400 Mesh | ± 0.004 mm (0.00015 inch) | ± 8% of nominal aperture | Tilt deviation ≤ 1° |
