What is the difference between profiled steel plate and sandwich panel?

Profiled steel plate. The biggest difference with the sandwich panel is that there is only one layer of profiled steel plate, and the sandwich panel is composed of three layers.

Profiled steel plate refers to the steel formed by cold pressing or cold rolling of thin steel plate. The steel plate is made of organic coated thin steel plate (or colored steel plate), galvanized thin steel plate, anti-corrosion thin steel plate (containing asbestos.

asphalt layer) or other thin steel plates, etc. The profiled steel plate has the advantages of light unit weight, high strength, good seismic performance, fast construction, beautiful appearance, etc., and is a good building material and component, mainly used in the enclosure structure.

floor slabs, which can also be used for other structures. According to the requirements of different functions, the profiled steel plate can be pressed into corrugated, hyperbolic waveform, ribbed, V-shaped, stiffened type, etc.

Sandwich panels, which are composed of two layers of molded metal panels (or other material panels) and polymer heat-insulating inner cores that are foamed and matured directly in the middle of the panels, are easy to install, lightweight, and efficient. The filling system also uses a closed foam molecular structure, which prevents the condensation of water vapor.

The profiled plate, also known as the corrugated plate, is generally a color-coated steel plate that is cold-bent into various wave-shaped platepieces by rolling.

Sandwich panels, also known as composite panels, are composed of color-coated steel plates or other panels and bottom plates and insulation core materials through binders (or foaming).

into insulation composite maintenance panels.

The simplest difference is: the profiled plate is a veneer and the sandwich panel is a composite panel.

Profiled steel plate. Profiled steel plate is a corrugated sheet made of cold-rolled thin steel plate as the substrate, galvanized or galvanized with color coating and then rolled into a corrugated sheet.

It has the characteristics of flexible molding, fast construction speed, beautiful appearance, light weight, easy industrialization, commercial production, etc., and is widely used as a wide material for the roof and wall enclosure of poor buildings.

1.In terms of core materials, there are six types:

Polystyrene sandwich panel is EPS sandwich panel (the most widely used variety in the market);

Extruded polystyrene sandwich panels, i.e., XPS sandwich panels;

Rigid polyurethane sandwich panels are PU sandwich panels;

Tripolyester sandwich panel, i.e., PIR sandwich panel;

Phenolic sandwich panel is PF sandwich panel;

Rock wool sandwich panel is RW sandwich panel.

Foam metal sandwich panels.

2.There are two types of panels:

There are two types of metal panels and non-metal panels. Metal panels are easy to process and can be made into various shapes, but in some occasions, non-metallic panels have a role that metal panels cannot reach, such as corrosion resistance, impact resistance, etc.

Characteristics of sandwich panels:

1. Light weight per square meter is less than 24kg, which can fully reduce the structural cost.

2. Quick installation, light weight, plugging, installation and can be cut at will, which determines the ease of installation, can improve efficiency and save construction period.

3. Fireproof, the surface material and insulation material of the color steel composite coreing board are non-combustible or flame-retardant materials, which can meet the requirements of fire protection specifications.

4. Refractory, the color steel plate treated by special coating is kept new for 10-15 years, and the anti-corrosion coating is sprayed every ten years, and the life of the plate is more than 35 years.

5. Beautiful, the clear lines of the profiled steel plate are as many as dozens of colors, which can meet the needs of any style of building.

6. Thermal insulation Commonly used thermal insulation materials are: rock wool, glass fiber wool, polystyrene, polyurethane, etc., with low thermal conductivity and good thermal insulation effect.

7. Environmentally friendly and noise-proof, the sound insulation strength of composite board can reach 40-50 decibels, which is a very effective sound insulation material.

8. The plasticity of the strong pressure steel plate can be cut arbitrarily to meet the needs of special design.

9. High strength Using high-strength steel plate as the base material, tensile strength of 5600 (kg cm2), coupled with the most advanced design and roll forming, it has excellent structural characteristics.

The profiled plate, also known as the corrugated plate, is generally a color-coated steel plate that is cold-bent into various wave-shaped platepieces by roller inspection.

Sandwich panels, also known as composite panels, composite the color-coated steel plate or its large side panels and bottom plates with the insulation core material through binders (or foaming).

into insulation composite maintenance panels.

The simplest difference is: the profiled plate is a veneer and the sandwich panel is a composite rolled rubber plate.

The profiled plate is generally a forming plate (mainly color steel plate) rolled by a single-layer metal plate through a profiler

Sandwich panels are made of various materials on both sides of the board or net or paper, and the middle core material is a thermal insulation material.

Now the sandwich panels on the market are mainly color steel sandwich panels, and the intermediate core materials are: polyurethane, rock wool, slag wool, glass wool, polystyrene, extrusion, etc.
