Steel Wire

Select gauge based on load and flexibility needs—thicker wire (lower gauge number) supports heavier loads but is less flexible; check specified tensile strength or breaking load for the required safety margin and match wire type (e.g., stainless, galvanized) to the environment

Common finishes include galvanized (zinc-coated) for general corrosion resistance, stainless for high corrosion or food-contact environments, and PVC-coated for added abrasion resistance and insulation; choose based on moisture, chemical exposure, and appearance requirements

Measure the total run plus allowance for knots or anchors; steel wire is usually sold by the foot, roll, or coil in standard lengths—buy a bit extra (10–20%) to account for waste and fittings

Common fittings include wire rope clips, swage sleeves, turnbuckles, and thimbles; you'll typically need wire cutters, swage/crimping tools or a hydraulic swager for sleeves, and appropriate safety gloves and eye protection

Regularly inspect for broken strands, corrosion, kinks, or wear at contact points; clean and apply compatible lubricants for non-coated wire, replace wire with broken strands or significant corrosion, and retension or replace fittings as needed

Use working load limits (WLL) derived from the wire's rated breaking strength with an appropriate safety factor (commonly 5:1 for lifting or higher depending on application), avoid shock loading, and follow industry-specific standards for rigging or structural uses

Construction affects flexibility and abrasion resistance: higher strand counts (e.g., 7x19) are more flexible and better for dynamic or pulley use, while lower strand counts (e.g., 6x36) offer higher strength and abrasion resistance for static or heavy-duty applications; core type (fiber vs. steel) influences compression and lubrication retention
