Brief Introduction
The polyurethane sandwich composite panel roofing system integrates thermal insulation and waterproofing functions. Featuring a stable structure, it delivers outstanding performance in waterproofing, wind resistance, heat insulation and sound absorption, together with high appearance adaptability. It is widely applied in industrial buildings, public venues, transportation facilities and commercial buildings.
Hongxinyuan metal‑faced roof sandwich panels adopt profiled steel sheets as both top and bottom facings. Core material options include rock wool (PU edge‑sealed) and glass wool (PU edge‑sealed). Edge filling enhances panel strength. The panels achieve reliable air‑tightness and water‑tightness as well as excellent thermal insulation. Fast construction also fulfills the design concept of energy‑saving roofing.
Corrosion Resistance
Aluminum foil can be used as an alternative to steel sheet for the inner panel. It provides a smooth and attractive interior surface and delivers effective resistance to high‑temperature and highly corrosive environments.
Well‑designed Longitudinal Joint for Roof Panels
The sloped‑face joint design at the minor edge of roof panel connections delivers superior strength and tight sealing performance.
Simple & Fast Construction for Heat Insulation and Fire Protection
Thermal insulation and fire‑protection functions for roofing are achieved in one single solution. Simple and rapid construction realizes the design concept of energy‑saving roofing.
High Inherent Strength of Roof Panel
Four‑wave corrugated profile improves the panel’s capacity against bending moment and deflection, which allows purlin consumption to be reduced according to actual conditions.
Aesthetic & Cost‑effective
The roof features strong structural visual effect with a wide range of optional colors, helping reduce material waste.
Metal Surface Insulated Sandwich Panel
Designed with a metal exterior and high-performance insulating core, this panel offers superior thermal insulation, soundproofing, and energy efficiency. It’s ideal for buildings where energy conservation and comfort are top priorities, ensuring long-term durability and reduced environmental impact.
