Product Description

Product Overview

This super-wide prepainted aluminum coil is customized for cleanroom sandwich panel inner & outer skins, applicable to pharmaceutical workshops, electronic dust-free workshops, medical labs, food sterile workshops and modular clean engineering. The maximum production width reaches 2650mm, greatly reducing cross seams of large-area clean panels, effectively lowering dust hiding spots at joints, improving the airtight, dust-proof and sterile performance of cleanroom enclosures. Equipped with multiple alloy options and antibacterial functional coatings, it meets all indoor, humid and outdoor clean building standards.
