SIW is honored to have collaborated with students from the CvE251 Material Testing course of the Department of Civil and Environmental Engineering, Faculty of Engineering, Srinakharinwirot University, on November 18, 2025, under the academic cooperation as outlined in the MOU.During this lecture, the company shared in-depth knowledge about prestressed concrete structures, the production process of steel wires used in construction, and quality control and testing systems in real-world industry applications. The aim was to give students a comprehensive understanding that combines both theoretical and practical perspectives. Additionally, a demonstration of the steel wire tension test was held in the university's laboratory to provide students with hands-on experience outside the classroom.We would like to express our sincere thanks to the course instructors, Assoc. Prof. Acting Maj. Ittiporn Sirisawat (Ph.D.), Assoc. Prof.Panuwat Joyklad (Ph.D.), and Assoc. Prof. Suniti Suparp, for warm welcome and continuous support.SIW is proud to contribute to the education of future engineers and hopes that this collaboration between SIW and SWU will continue to foster the development of knowledge, technology, and talent in the future.#SIWxSWU #AcademicCollaboration #DevelopingFutureEngineers#CivilEngineering #UniversityIndustryCollaboration #SIW #SiamIndustrialWire

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

🚫 Don’t paint over rust!Painting directly on rust allows it to keep eating the steel underneath, weakens the structure, and causes the paint to peel or blister.✅ The right way:1. Remove rust until bare metal2. Apply anti-rust primer3. Paint over againResult = Safe, Strong, Durable 💪#AntiRust #ProTips #SteelCoating #SafeStructures

⚠️ Precautions When Driving Piles !1. Underground utilities: Signal cables, water pipes, and electrical lines — if not properly checked, can cause pipe breaks and water leaks, affecting both the worksite and the community.2. High-voltage power lines above the work area: Cranes or pile drivers may hit the lines, posing serious risks to workers.3. Nearby buildings or structures: Pile driving can cause vibrations that may damage adjacent buildings, houses, or fences.SIW is ready with a team of professional engineers and experts!Worry-free at every step, from start to project completion.📞 Contact us through any channel today.#PileDriving #PileDrivingService #SIWService #EngineeringTeamReadyToConsult #ConstructionSafety

We can’t control the weather, but we can plan ahead.Don’t let rain slow you down, use these simple techniques to keep your project on track, protect your materials, and avoid costly delays.1. Check the Weather DailyMonitor forecasts every morning to adjust your work schedule accordingly. 2. Drain Standing Water DailyNever leave water to pool at the site. It can weaken soil conditions and threaten the stability of the foundation and structure.3. Start with Indoor Work FirstPrioritize indoor or covered tasks first. This allows construction work to continue with minimal disruption, even during periods of rain.4. Protect Materials and EquipmentStore cement, steel, wood, and electrical tools in dry areas or cover them with waterproof tarps to avoid damage and reduce replacement costs.5. Set Up Temporary Drainage SystemsUse temporary drainage systems like trenches or PVC pipes to quickly redirect rainwater and keep the site safe and operational.💡 Small steps like these can save time, reduce costs, and maintain construction quality—even during the rainy season.Plan smart. Store safely. Prevent damage before it happens.#ConstructionTips #RainySeasonReady #SiteManagement #ProjectPlanning #BuildSmart
