| Steel Angle Bars | Construction frameworks, machinery | Non-alloy steel (ASTM A6/A6M), Yield strength Q195-Q420 (GB/T 700), ±5% tolerance (ASME B16.5), fabrication services (ISO 9001) | Cost-effective (▲ vs stainless steel), customizable fabrication, ASME compliance | Prone to corrosion without coating, heavier than aluminum (▲▲ lighter options available) |
| Aluminum Angle Bars | Automotive, aerospace, lightweight apps | Aluminum alloy (e.g., 6061-T6, 5052), Yield strength 240-276 MPa (ASTM B221), density 2.7 g/cm³ | Lightweight (▲▲ vs steel), corrosion-resistant (▲ vs galvanized steel), high strength-to-weight ratio | Higher cost than steel, less durable in high-stress scenarios (▲▲ steel for heavy loads) |
| Stainless Steel Bars | Chemical plants, marine environments | Austenitic stainless (e.g., 304/316), corrosion resistance (ASTM A240), yield strength 505-520 MPa (304) | Excellent corrosion resistance (▲▲ industry standard), high strength (▲▲ vs aluminum) | Expensive (▲▲ cost barrier), harder to weld, heavier (▲▲ weight vs aluminum/composites) |
| Galvanized Steel | Outdoor structures, agriculture | Zinc coating (ASTM A123), corrosion resistance up to 20 years (ISO 1461), ±5% tolerance | Enhanced corrosion protection (▲ vs plain steel), cost-effective (▲▲ vs stainless) | Coating wears off over time, heavier than aluminum (▲▲ weight penalty) |
| Structural Steel Beams | High-rise buildings, bridges | I-beam/H-beam profiles (AISC), load capacity up to 500 MPa (ASTM A992), thick sections | Exceptional load-bearing (▲▲ industry standard), standardized for large projects | Bulky (▲▲ space constraints), limited customization, high cost for large sections |
| Composite Profiles | Aerospace, specialized machinery | Fiberglass/carbon fiber (ASTM D790), customizable profiles, strength-to-weight ratio 1:10 | Lightweight (▲▲ industry leader), durable in extreme conditions (▲▲ corrosion/heat) | High cost (▲▲ prohibitive), limited availability, requires specialized handling |
