Metal notes
Practical articles for buyers comparing mesh, perforated metal, grating, and structural steel choices.
Learn the three conditions that make McNichols bar grating load tables valid: material, span, and environment. Avoid overloading and corrosion failures.
Learn why 316 stainless steel is the cost-wise choice for McNichols round perforated metal in coastal and chemical service, despite a 30-40% higher price than 304.
Choosing McNichols expanded metal mesh means choosing the alloy first. Compare 3003, 5052, 6061, 304, and 316 by chloride exposure and load to pick the right mesh.
Detroit scrap prices now follow verified alloy chemistry, not magnet tests. See the 304 vs 316 gap, aluminum alloy sorting, and a yard-ready verification workflow.
Coastal buyer? Learn why 'round' in perforated metal means holes, not sheets, and how 5052 aluminum stacks up against 304/316 stainless for salt-air duty.
Learn why a custom aluminum heatsink pricelist is quote-driven, what drives cost, and how to compare quotes with RFQ tools and certifications.
Aluminum, steel, or stainless McNichols expanded metal? Compare corrosion, strength-to-weight, and lifecycle cost—then pick 316 for coastal, 304/aluminum for indoor.
McNichols bar grating load tables link span, material, and allowable load. This guide shows why deflection, not strength, usually decides the safe rating.
Detroit scrap iron and metal buying: how 304 vs 316 stainless and 3003 vs 6061 aluminum change your lifetime cost. Grade certificates matter more than per-ton price.
Aluminum and aluminium are the same metal element. This guide explains how to specify 6061 alloy correctly in RFQs and certifications, regardless of spelling.
