Metal Sandwich Panel

Home » Product » Metal Sandwich Panel

Introduction

Metal sandwich panels are also called “sandwich panels”. The upper and lower layers are metal sheets, and the middle is a fireproof core material. They are made into composite panels by high temperature and pressure curing. They have functions such as heat insulation, heat preservation, fire prevention, and sound insulation.

We provide you with metal sandwich panels of various sizes, colors, and patterns. The products have the characteristics of long service life, strong decorativeness, convenient installation, fire prevention, and heat insulation.

Metal Sandwich Panels Advantages

Lightweight and high strength: The weight of metal panels and core materials is relatively light, especially aluminum, which is lighter. At the same time, it is also strong in bending and compression resistance.
Strong thermal insulation performance: The core material has a low thermal conductivity, which can significantly reduce energy consumption and achieve energy-saving effects.
Good fire resistance: Different core materials have different fire resistance levels. We use the lowest B2 fireproof level, and the surface is coated with flame retardant. A1-B2 can meet the needs of different projects.
Strong corrosion resistance: The metal panels are all made of highly corrosion-resistant metal materials. They are not easily corroded in humid, acidic and alkaline environments and have a long service life.
Convenient installation: The metal sandwich panels are prefabricated and processed in the factory, which can be assembled quickly. The construction is simple and efficient, reducing construction costs.
