What is "Fatigue"?Why Must Strong Structures Pass This Test?In engineering, a material being strong doesn’t always mean it’s durable.What’s more challenging than tensile strength is repeated loading, also known as Fatigue.What is Fatigue?Fatigue is the weakening of a material caused by repeated loading and unloading.For example, steel wires used in prestressed concrete, piles, or bridges may not break from a single force.But after tens or hundreds of thousands of repeated stresses, the material becomes "fatigued" — and can fail without warning.Examples of Fatigue-Related Failures:Bridge cables snapping after just a few years of useStructural collapse due to continuous vibrationsDamage invisible to the naked eyeWhy Perform Fatigue Testing at SIW-Testing Service Center?1. Internationally Certified StandardsSIW operates the only wire testing lab in Thailand certified for Fatigue Testing by NATA (Australia’s national lab accreditation body).This guarantees that all equipment and processes meet strict international standards.2. Real Testing — Beyond TheoryWe simulate repeated stress cycles to determine how many times your wire can withstand force before failure.You’ll receive detailed reports with clear graphs, backed by advanced tools and expert analysis.3. Supporting Nation-Level ConstructionSIW supports major infrastructure projects—expressways, bridges, rail systems—where high-performance wire is critical.Fatigue testing is a key step before the wire is ever used in the field.

High-strength steel wires for prestressed concrete can change their structural properties immediately when exposed to heat. They may become brittle and break when pulled. To prevent damage, follow these precautions:1. Avoid sparks from welding or cutting metal.If welding or cutting near the wire, cover it with a wet cloth to protect it from sparks or heat.2. Check welding cables to ensure they are in good condition.As damaged cables may scratch or mark the wires during handling.3. Do not use welding wire to cut tensioned wires.As sparks can cause damage or break the wire.#SteelWire #ConcreteConstruction #SafetyFirst #ConstructionSafety
