Material Composition | Outdoor Advertising Fixtures | Industry: Carbon Steel (ASTM A36, 200-250 Brinell) ▶ Base: 304 Stainless Steel (ASTM A240, 18-8% Cr-Ni) ▲ ▶ Advanced: 316 Stainless Steel (ASTM A240, 18-12% Cr-Ni) ▲▲ | Base/Advanced resist corrosion 5x longer than Industry (salt spray test) | Advanced variants cost 30-50% more than Industry-standard materials |
Finish Type | Aesthetic Indoor/Outdoor Installations | Industry: Matte Finish (ISO 4287 Ra 3.2 μm) ▶ Base: Satin Finish (Ra 1.6 μm) ▲ ▶ Advanced: Satin + Polished Edges (Ra 0.8 μm) ▲▲ | Base/Advanced reduce glare and improve grip in humid environments | Premium finishes require specialized polishing, increasing production time |
Load Capacity | Heavy-Duty Signage Support | Industry: 500 kg (ASTM F1289) ▶ Base: 700 kg ▲ ▶ Advanced: 1,000 kg ▲▲ | Base/Advanced support 40-100% heavier loads than Industry, ideal for large ads | Advanced variants may add weight, complicating installation logistics |
Thread Precision | High-Precision Mechanical Assemblies | Industry: ISO H8 Tolerance ▶ Base: ISO H7 ▲ ▶ Advanced: Custom精密 H6 ▲▲ | Advanced threads ensure 50% tighter fits, reducing wear in dynamic systems | Custom精密 threads require specialized CNC machining, raising costs |
Corrosion Resistance | Coastal/Marine Environments | Industry: 24hr salt spray (ASTM B117) ▶ Base: 48hr ▲ ▶ Advanced: 96hr ▲▲ | Advanced variants withstand 4x longer exposure to saltwater than Industry | Enhanced corrosion resistance requires alloying with costly metals like molybdenum |
Surface Treatment | Industrial Harsh Environments | Industry: Zinc Plating (ISO 4042, 5-10 μm thickness) ▶ Base: Electroless Nickel ▲ ▶ Advanced: Stainless Surface (no plating) ▲▲ | Advanced versions eliminate plating failure risks, ideal for chemical plants | Stainless surfaces require no maintenance but are harder to repair if damaged |
