Engineering Performance: Custom Loading Profiles

Sunli relies on our dedicated team of 28 skilled R&D engineers to develop high-performance warehouse structures. We design to improve structural stability and optimize material usage, introducing over 120 new products and structural improvements annually.

Our engineers use advanced CAD software, Finite Element Analysis (FEA), and 3D printing prototyping to evaluate how complex racking assemblies respond under full-capacity weight loads. We customize racking height, depth, column thickness, and beam profiles to match regional seismic zone safety codes.

Whether integrating smart shuttle carts, cold-chain drive-in systems, or multi-level mezzanine structures, our R&D group provides comprehensive engineering support from initial CAD concept drawing to final structural certification.

"Our engineering goal goes beyond saving space—we focus on building load-bearing structures that maintain structural alignment over decades of intense industrial forklift operation."
