Yumisteel Training for Corrugated Sheet

First the trainer Alina opened the session by decoding Yumisteel’s corrugated sheet portfolio. She detailed how gauge thickness impacts structural load capacity, emphasizing that Aluzinc-coated sheets outperform standard galvanized steel in salt-spray tests. Key profiles like 4-wavefor roofing and agricultural grade for vertical installations were compared, highlighting tensile strength (300-550 MPa) and spans (0.6m–1.2m between purlins). Alina stressed how custom trim kits prevent edge lifting during typhoons – a critical specification for coastal projects. Attendees received spec sheets detailing thermal expansion coefficients and compatibility with ISO-certified fasteners.

The second module transformed theory into practice. Alina demonstrated corrugated sheet installation using Yumisteel’s system, showing how pre-drilled pilot holes prevent micro-fractures in the coating. She debunked myths about silicone sealant compatibility, proving Yumisteel’s PVDF fluoropolymer coating resists adhesive degradation. Using accelerated weathering samples, he contrasted chalking resistance between standard polyester (8-year fade warranty) and Yumisteel’s HDP finish (15-year warranty). For lifespan optimization, Alina shared field data: proper end lap sealing reduces corrosion failures by 70% in high-humidity zones. The "why" behind side-lap screw patterns (every second corrugation) to prevent oil-canning drew audible nods from seasoned installers.

Yumisteel's training empowered sales and technical teams with actionable insights on corrugated sheet performance. Attendees now confidently articulate coating's corrosion resistance, precise installation protocols for warranty-backed longevity, and ASTM compliance as competitive differentiators ,directly translating expertise into client trust and sales growth.
