Product Description

Product Description

EPS Sandwich Panels

EPS sandwich panels are a composite building material featuring a core of expanded polystyrene (EPS) foam firmly bonded between two structural facings, typically metal sheets. This efficient sandwich panel construction provides excellent thermal insulation, structural strength, and lightweight properties, making them a premier choice for energy-efficient wall and roof systems in warehouses and cold storage facilities.

Joint way

There is no space and screws are hidden and covered,when installation.This connection way of roof sandwich panels can make the roof system have much more better waterproof performance than common roof sandwich panels.

Product advantages

Lightweight
Because of light density,it makes the EPS sandwich panels in lower weight,and makes the installation more easier.
Various colors
Many colors choices for you to choose for your buildings.
Long life
If the coating types are selected properly,the sandwich panels could be long life and less maintenance.
Waterproof
The joint type is hidden screws type,which make it act more better in waterproof performance.
Sound insulation
EPS sandwich panels is with 3 layers' materials,which is far more better than single layer steel sheet on sound insulation function.
Good price
EPS sandwich panels price is the best among all the kinds of sandwich panels.
Easy installation
It's easy installation to save the construction period.

Product application

EPS roof sandwich panels are extensively used in prefabricated houses, flat-packed container homes, poultry farms, warehouses, and cold storage facilities. These roof panels offer exceptional thermal insulation, structural strength, and quick installation, providing a durable and energy-efficient roofing solution for diverse building projects.

Packing & Delivery

Container type	Panel type	Max Length(M)	Loading quantity(M)	Loading quantity(M²)
20FT	Roof panel	5.9	271.4	257.83
40FT	Roof panel	11.9	595	565.25
Note:1,This calculation is based on max length;          2,We could also accept other special container type,like 45HQ;         3,This is the loading quantity reference for 75mm thick roof sandwich panels.

The roof sandwich panels could be sealed by sealing tapes,and loading is by our factory crane.And we will also put the thick EPS foam to protect the panels from crashing each other.

Some special notes

Protective films
All the sandwich panels that Yumi steel made are covered with a layer of PVC protective film.This PVC protective film must be removed within 4 months,after sandwich panels production.Otherwise there will be chemical reaction,and make the PVC film so difficult to be removed.Also if you want to store panels for long time,please protected the panels from sun exposure,high temperatures and other bad atmosphetic conditions.
Cutting for sandwich panels and flashings
Please use proper tools to cut the panels and flashings.Don't make overheat for the steel sheets,otherwise it will do harm to the zinc coating and cause corrosion.Also it will have damage to core material.Please use circular saws for metal cutting.When cutting panels remove excess metal filings that can cause corrosion, and prevent sparks and filings from falling onto other panels.
Dark colors warning
We do not recommend to use dark colors for sandwich panels.Because of sunlight absorption and overheating of steel sheets on panels.Steel temperature expansion and possible damages will be caused by overheating.Also temperature changes may result in deterioration of aesthetic or damage of panels.
Color difference
We can not make sure for same color,if you don't make order at one time.Please be noted,thank you.
Size tolerance
There will be material tolerance for width,length,steel sheet thickness of sandwich panels.If you want them to be no less than which size,please indicated,when make orders.Then we will ask steel mill and our production team to be noticed about the requirement.
