Zero-waste metal mesh. Full strength, full visual impact.

Pricing for expanded metal panels varies significantly based on material thickness (typically 1.0–3.0 mm), pattern (SWD/LWD), panel size, and finish. These ranges reflect Foshan export pricing for commercial architectural volumes (hotel lobbies, facades, ceilings) and include basic fabrication but exclude shipping, framing, or installation. Custom patterns or heavy gauges increase costs by 20–40%.

• Pricing drops 15–25% for standard patterns and orders over 500 sqm.
• MOQ pricing assumes minimum 100 sqm; smaller runs add 30–50% premium.
• All prices are FOB China; factor 10–20% for international freight and duties.

Material choice directly impacts long-term durability in different climates. Salt spray testing (ASTM B117) and real-world exposure data provide clear benchmarks for hotel lobbies, exterior facades, and coastal projects.

• Aluminum relies on protective finishes; once breached, it corrodes faster than stainless.
• 304 SS offers good general corrosion resistance but is vulnerable to chlorides.
• 316 SS contains 2–3% molybdenum, dramatically improving pitting resistance in salt-laden air.
• Caveat: All materials perform best when properly framed to avoid water pooling; regular cleaning extends service life in all environments.

Open area percentage (the proportion of empty space in the panel) is one of the most frequently requested specifications because it controls light transmission, ventilation, privacy, and shading while directly affecting panel stiffness.

• Higher open area increases airflow and daylight but reduces panel strength, often necessitating additional support frames or heavier base gauges.
• Lower open area provides better privacy and solar shading but can restrict ventilation and increase material weight/cost.
• Typical architectural sweet spot: 55–65% open area for most facade and ceiling applications.

Standard sheet sizes minimize cost and lead time, while custom panels are fabricated to exact project dimensions for seamless installation.

• Standard sizes are cut from mill sheets with minimal waste; custom requires dedicated tooling/setup.
• MOQ for powder-coated or anodized custom runs is typically 100 sqm; PVD or specialty finishes may require 200 sqm.
• Smaller prototype orders (under 50 sqm) are possible at 30–50% premium.

Lead times depend on pattern complexity, finish type, and current factory load but follow predictable industry benchmarks for architectural projects.

• Samples include 2–3 finish options and are shipped via air freight for fast approval.
• Bulk orders include full QC documentation, material certifications, and packing for sea freight.
• Expedited options can shave 7–10 days but add 15–20% to cost.

Proper installation ensures structural integrity, alignment, and long-term performance. Most architects specify framed systems for ease of mounting and future maintenance.

• Facade cladding: Panels are mounted on extruded aluminum sub-frames using Z-clips, hook-on systems, or concealed brackets; fixed with stainless steel fasteners; designed with 10–20 mm joints for thermal expansion.
• Ceilings: Suspended on T-bar grids, lay-in framed panels, or swing-down access frames; must maintain minimum open area for sprinkler compliance; often combined with acoustic backing.
• Interior partitions and balustrades: Framed into steel or aluminum extrusions, bolted or welded to posts; tempered glass infills optional for hybrid designs.

All methods require coordination with structural engineers for wind loads (facades) and seismic requirements where applicable.

Each grade balances weight, cost, strength, and environmental resistance. Selection is driven by exposure, budget, and maintenance expectations.

• Choose aluminum for interior or protected exterior where weight and cost matter most.
• Use 304 SS for general commercial interiors and mild-climate facades.
• Specify 316 SS for coastal hotels, marine-adjacent projects, or high-humidity atriums.
