This highlights the structural advantage of our integrated manufacturing ecosystem. In Step 2 (Shop Drawing), the engineering parameters of both aluminum systems and interior wood doors are consolidated into a centralized master blueprint to cross-check tolerance thresholds. Prior to wrapping in Step 3 (Precision Processing), we enforce cross-workshop multi-material joint verification and physical test-assemblies. This guarantees that different materials align flawlessly in coating alignment and hardware cohesion, eliminating field fitment errors entirely.
