Small details often overlooked ! Before steel wires can be used, proper storage is key.
Protect your materials easily with 4 tips to store steel wire safely:
✅ PC Wire: Stack Properly for Faster & Safer Transport.
✅ PC Strand: Use Wooden Wedges to Prevent Rolling.
✅ First in First out: Store in Order: First In, First Out.
❌🔥 Avoid areas with sparks or high heat, which may cause the wire to break under tension. Store in a shaded, dry, and well-ventilated area.
Our PC Wire and PC Strand are manufactured to international standards and trusted by customers both locally and abroad. We guarantee quality from production to delivery, ensuring you receive steel wires you can rely on at every step. 💪

เรามาทำความรู้จักกับลวดเหล็กสปริง กันดีกว่ามีกี่ชนิด ลวดสปริงสามารถแบ่งออกเป็นชนิดต่าง ๆ ดังนี้ 1. Hard Drawn Steel Wire - (JIS G 3521) ลวดเหล็กที่ผลิตภายใต้กระบวนการรีดเย็น โดยใช้เหล็กลวดที่มีส่วนผสมของคาร์บอนสูง ที่เหมาะกับการใช้ผลิตในหลากหลายอุตสาหกรรม เช่น ยานยนต์ เครื่องจักรกล เครื่องใช้ไฟฟ้า เป็นต้น โดย Hard Drawn Wire แบ่งเป็น 3 เกรด คือ SWA SWB และ SWC แต่ละเกรดมีคุณสมบัติที่แตกต่างกันไปขึ้นอยู่กับประเภทการใช้งาน 2. Piano Wire - ลวดเปียโน (JIS G 3522) ลวดเปียโนผลิตจากกระบวนการรีดเย็น โดยใช้ลวดเหล็กที่มีส่วนผสมคาร์บอน ด้วยคุณภาพที่ดีนี้ ลวดเปียโนจึงนำมาใช้ในการผลิตสปริงที่มีคุณภาพสูงเป็นพิเศษ เช่น สปริงในอุตสาหกรรมยานยนต์ โช๊ค เครื่องยนต์ อาทิ สปริงวาวล์ สปริงเบรค สปริงคลัชท์ หรือ เครื่องใช้ไฟฟ้าบางประเภท เป็นต้น ซึ่งลวดเปียโนสามารถแบ่งเกรดเป็น SWPA, SWPB และ SWPV โดยแต่ละเกรดมีความเหมาะสมในการใช้งานที่แตกต่างกันไปตามประเภทงาน

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.
