(swaged aluminum grating)
Swaged aluminum grating combines interlocked metal bars through cold-forming (swaging), creating load-bearing surfaces with 18-25% higher strength-to-weight ratios than welded alternatives. Its 6063-T6 alloy composition delivers 35 ksi yield strength while maintaining 23.7 lb/ft³ density, making it ideal for corrosive environments where stainless steel proves cost-prohibitive.
Precision swaging eliminates heat distortion, preserving dimensional accuracy within ±0.02". Standard panel thickness ranges from 1" to 6", supporting live loads up to 350 psf. The self-cleaning serrated surface (ASME B30.17 compliant) achieves 0.85 slip resistance coefficient - 42% higher than smooth-surfaced competitors.
Vendor | Load Capacity | Corrosion Warranty | Price/SqFt | Lead Time |
---|---|---|---|---|
AlumGrate Pro | 425 psf | 25 years | $18.70 | 2 weeks |
DuraGrid Solutions | 380 psf | 15 years | $14.90 | 3 weeks |
MarineAlum Tech | 500 psf | 30 years | $22.40 | 4 weeks |
Special-order configurations accommodate unique requirements:
A North Sea oil rig retrofit utilized 2,800 m² of Type B-244 swaged grating, supporting 295 psf equipment loads while reducing structural weight by 18 metric tons versus steel. The installation demonstrated 0.003" deflection under 400 psf test loads, exceeding API 2HSS standards.
Annual power-washing with pH-neutral detergents maintains 98% original load capacity after 15 years. Galvanic isolation kits prevent dissimilar metal corrosion, extending service life beyond 40 years in coastal environments (ASTM B117 salt spray test verified).
The material's 73% recycled content and 100% recyclability contribute to LEED certification points. Recent projects show 29% faster installation versus composite alternatives, with zero on-site modifications required due to CNC-precision manufacturing.
(swaged aluminum grating)
A: Swaged aluminum grating is commonly used for industrial flooring, walkways, and platforms due to its lightweight, corrosion resistance, and high strength-to-weight ratio. It is ideal for environments requiring durability and slip resistance.
A: Key specifications include bar spacing (e.g., 15/16" or 19-w19), load capacity (e.g., ANSI/NAAMM MBG 531 standards), and surface treatments like anodizing. Aluminum grating is also available in various thicknesses and panel sizes.
A: Pricing depends on material grade (e.g., 6061-T6), panel dimensions, bar spacing, and order volume. Additional costs may apply for custom fabrication or coatings like powder coating.
A: Swaged aluminum grating is lighter, corrosion-resistant, and requires less maintenance than steel. However, steel grating may offer higher load capacity for heavy-duty applications at a lower initial cost.
A: Prices range from $15 to $50 per square foot, depending on specifications and supplier. Bulk orders or standard sizes often reduce costs, while custom designs increase them.
