· Complies with GB/T 13912-2020, zinc layer ≥85μm, passing 720-hour salt spray test with zero rust. Suitable for workshop water supply/drainage and compressed air pipelines.
· Inner wall coated with epoxy resin (thickness ≥200μm) to resist industrial exhaust condensate corrosion, extending service life to 15 years.
· Steel yield strength ≥235MPa, tensile strength ≥375MPa, inspected by UT ultrasonic testing to ensure no internal defects.
· Pre-treated with sandblasting (Sa2.5 grade) and hot-dip galvanizing before delivery, enabling direct on-site hoisting and splicing, reducing anti-corrosion construction time by 90%.
· Forged from Q235B carbon steel, matching galvanized pipes. Pre-machined welding grooves (angle 37.5°±2°) ensure zinc layer repair rate ≥95% after welding.
· Paired with high-strength electrodes (J422), joint tensile strength reaches 420MPa, meeting anti-fatigue requirements for vibrating equipment connections.
Total Supply: 500 tons of galvanized pipes, 100 tons of I-beams, 100 tons of angle irons, 4,000 galvanized welding fittings.
Efficiency Gains: Steel structure installation cycle shortened by 35%; rainy-season construction unaffected by surface treatment, workshop capping completed 15 days ahead of schedule.
Cost Optimization: 20% lower comprehensive cost than fragmented sourcing; steel loss rate reduced from industry average 5% to 1.5%, saving $120,000 in material costs.
Compliance Assurance: All products certified by TISI; galvanized layer adhesion passes 10-cycle copper sulfate test without peeling, meeting Thailand’s industrial building seismic design code (TC-24).
"Thailand’s high-temperature and humid environment poses severe challenges to steel materials. The supplier’s hot-dip galvanized products perfectly solved the corrosion issue—especially the pre-treatment process for I-beams and angle irons, allowing fast construction even in the rainy season. The one-stop procurement model eliminated the hassle of coordinating multiple suppliers, and the on-site technical team ensured steel structure installation accuracy, enabling the project to meet equipment move-in conditions 20 days ahead of schedule.
