Buildings in tropical coastal cities face extremely harsh environmental challenges all year round. The sea wind carries large amounts of salt particles that will slowly corrode ordinary building materials, causing traditional concrete walls to peel off, steel bars to rust, and the whole building structure to age prematurely. The EPS Cement Sandwich Panel’s special anti-corrosion formula makes it perfectly suitable for these high salt spray coastal environments.
The cement facing layer of the panel is added with a special salt-resisting additive, which prevents chloride ions in the salt spray from penetrating into the panel interior. Even after 3000 hours of strict salt spray test, the panel surface shows no sign of corrosion, no peeling and no strength loss. Unlike metal wall panels that rust quickly in coastal areas, this panel will never produce rust stains that flow down and pollute the wall surface. When you cut slots on the panel for plumbing and wiring, the cement-based filling material you use to seal the slots also has the same anti-corrosion performance, so the whole wall system forms a complete anti-corrosion protective layer. Many seaside resorts, coastal fishing port warehouses and island residential buildings have adopted this panel, and after 10 years of use near the sea, the walls still stay intact, no corrosion damage at all. It greatly extends the service life of coastal buildings and reduces the expensive annual anti-corrosion maintenance cost.
