Application Scenarios

This 50mm EPS panel is widely adopted for industrial, commercial, agricultural and modular construction sectors.

It works great for internal partition walls and lightweight external wall cladding for light steel workshops, logistics warehouses and factory auxiliary buildings.
Suitable for temporary public facilities: exhibition halls, shopping mall retrofit partitions, community service buildings and portable restrooms.
Ideal agricultural building material for livestock breeding sheds and farm storage warehouses.
Preferred wall & roof material for site offices, labour dormitories, container type modular houses and emergency resettlement shelters.

It represents an efficient and budget friendly building solution for non extreme environment construction projects.

Advantages

The 50mm EPS panel combines practical functional performance with outstanding cost efficiency:
1. Excellent thermal insulation: Low thermal conductivity stability indoor temperature and cuts building energy consumption.
2. Controllable fire performance: B1 / B2 flame retardant grades comply with international standards to satisfy basic fire safety requirements for most civil and industrial projects.
Note: B2 grade EPS is not suitable for projects requiring high fire resistance standards. Select B1 grade for higher risk fire rated applications.
3. Water proof & air tight performance: Concealed interlocking tongue and groove joint delivers seamless installation and prevents water ingress and air leakage.
4. Durable steel facings: High quality coated steel offers good anti rust and anti ageing performance for long term outdoor usage.
5. Decent sound insulating effect: Reduces noise transmission to improve indoor working & living comfort.
6. Fast modular erection: Prefabricated panel design minimizes on site work, shortens overall construction period and lowers site labour cost.
7. Light weight benefit: Reduces structural and foundation investment for low load building projects.

FAQ

1.What is the MOQ?

Minimum order quantity is one 20GP container. Small trial orders negotiable. Custom color or special edge may require higher MOQ.

2.Reference loading capacity (Wall panel, effective width 1000mm)

50 mm EPS panel: 950‑1100 m² /20GP; 1900‑2200 m² /40HQ
Note: Roof panels, extra‑long panels and accessories will reduce loading volume. Final loading layout will be offered after confirming your exact specs.

3.Why does the price differ?

The final price is determined by multiple key factors: panel thickness, density of the EPS core material, and fire‑resistance rating (B1 or B2 grade).

4.Which projects can use EPS sandwich panels? Are there any restrictions?

Our EPS panels work for warehouses, workshops, prefab modular buildings, agricultural breeding sheds and temporary exhibition & commercial buildings.
Key restrictions:
This panel has no published load‑capacity data and should not be used for multi‑story or high‑load projects.
For projects demanding high fire‑resistance standards, please contact us to obtain fire test reports and official classification details for pre‑confirmation.
Send us your project requirements and we will check product compatibility for you.

5.How do I decide the proper panel thickness for my project?

Project	Thickness	What to Confirm
Basic enclosure / temporary building	50 mm	Local thermal and fire requirements.
General warehouse / workshop	50–75 mm	Climate, indoor temperature target and local code.
Higher thermal insulation	75–100 mm	Required U-value / R-value and energy target.
Hot climate / stronger insulation target	100–150 mm	Calculated thermal performance and coating exposure.
Higher fire requirement	Project-specific	Exact tested classification; alternative core if required.
