A composite roofing tile with a galvanized steel core bonded between an ASA weather cap and a PVC base. It marries the load-bearing strength of steel with the acid-, alkali- and salt-resistance of engineering resin — built for industrial and highly corrosive environments where both a bare metal sheet and a plain resin tile fall short.
PSP tile is our industrial anti-corrosion line. It is a different animal from our synthetic resin tile — it has a steel core inside, so it carries load like metal while the resin skins keep it from rusting.
A galvanized steel core gives the tile the span and load-bearing capacity of a metal roof, while the ASA and PVC layers seal the steel away from acid rain, salt air and chemical fumes that would rust a bare sheet within years.
It is specified where ordinary color-coated steel fails fast — chemical and fertilizer plants, coastal and high-salt zones, aquaculture and wet processing. The resin skin resists acids, alkalis and salts that eat through paint and zinc.
The metal core lifts fire performance to Class A (tested by China's national fixed-fire-fighting & fire-resistant components quality inspection centre) — a level plain resin tile (B1) cannot reach.
The composite build damps rain noise and drum, insulates better than bare metal, and has a low thermal-expansion coefficient so it stays dimensionally stable across hot-cold cycling. Color is held in the ASA cap, not surface paint.
Unlike our pure-resin tile, the PSP tile has a metal heart. The steel core is laminated between an ASA weather cap and a PVC base so the steel never contacts the corrosive atmosphere.

Verified material and performance data is shown below. PSP tile is made to order, so dimensional rows are confirmed against the factory spec sheet per project — we mark those TBD rather than publish a guessed number.
