(stick welding expanded metal)
Stick welding expanded metal combines two critical industrial processes: shielded metal arc welding (SMAW) and metal expansion technology. This method creates durable mesh products with 38-42% open area ratios, ideal for platforms requiring both structural integrity and airflow. The process enables 15-20% faster production compared to alternative welding methods while maintaining tensile strengths of 65,000-80,000 PSI.
Superior bond penetration (0.25-0.35" depth) ensures joint reliability in critical infrastructure projects. Key benefits include:
| Manufacturer | Material Grade | Thickness Range | Open Area % | Price/Sq.Ft |
|---|---|---|---|---|
| SteelFab Pro | A36 Mild Steel | 3-12 gauge | 42 | $4.20 |
| MetalWorks Industrial | ASTM A1011 | 1-10 gauge | 38 | $3.85 |
| Allied Expanded Tech | Galvanized CS | 5-14 gauge | 45 | $5.10 |
Specialized configurations account for 32% of current market demand. Common customizations include:

A: Use short, controlled bursts to avoid overheating the mesh. Maintain a 45° electrode angle for better penetration. Clean slag promptly to ensure strong welds.
A: Yes, mild steel expanded mesh welds well with E6013 or E7018 electrodes. Keep amperage low to prevent burning through thin strands. Tack-weld joints first for alignment.
A: Clamp the mesh tightly to a heat-resistant surface. Weld in staggered sequences to distribute heat evenly. Allow gradual cooling instead of quenching.
A: 3/16" to 1/4" strand thickness is ideal for structural applications. Thinner gauges (12-16) require lower amperage settings. Match electrode size to material thickness.
A: Remove oil, rust, and coatings with a grinder or wire brush. Degrease surfaces before welding. Light grinding improves arc stability and weld quality.
