Why Wanxiang

We have more than 20 years experience of construction industry. Our rock wool sandwich panel has even fiber distribution, strong interlayer bonding and A-class non-combustible. These panels offer good thermal insulation, sound absorption and structural stability, securing reliable projects.

Quality is ensured by full-cycle controls. We check rock wool purity and substrate quality, monitor production in real time, and verify products before shipment. We also provide flexible customization, including size, color coating and performance specs. Custom solutions are ready in 48 hours. They suit special span designs and harsh environments, like high-temperature, high-humidity, noisy and corrosion-prone areas.

Core Advantages

Excellent fire resistance & sound insulation: With non-flammable rock wool core, it blocks fire and reduces noise, fitting factories, schools and public buildings.
Moisture resistance & stable structure: It doesn't absorb water easily and stays firm, working well in damp or outdoor environments.
Easy installation & wide use: It's light and simple to set up, suiting quick construction projects and large-span structures.

FAQs

Q: What is rock wool sandwich panel?

A: It is made by bonding and pressing double-sided metal panels (mostly color steel plates) with a rock wool core in between.

Q: Where are rock wool sandwich panels applied?

A: Widely applied in workshops, warehouses and factories, along with public and residential buildings, fit wall and roof installations.

Q: Is the compressive and flexural strength sufficient?

A: It depends on panel thickness, core density and composite process. Standard products meet the enclosure and load-bearing needs. Custom thickened panels or high-density cores are available for special cases.
