Steel Plate Eps Metal Wall

Product Introduction

Steel Plate EPS Metal Wall is an innovative building solution. The outer steel plates lend it strength and durability, while the EPS inner layer provides excellent heat insulation. This makes it energy - efficient. It resists corrosion well, making it perfect for industrial structures, factory walls, and large - scale storage facilities, delivering long - lasting performance.

Product Specifications

Quality Assurance

The company has established a first - rate material testing center laboratory. Equipped with over 30 pieces of professional equipment, it serves two main purposes. Firstly, it comprehensively tests the physical, mechanical, and combustion properties of raw materials, auxiliaries, and finished products in the enclosure system. Secondly, it actively participates in new product R & D. Moreover, every operation in the lab adheres strictly to international standard operating procedures, ensuring high - quality and reliable results.

A Steel Plate EPS Metal Wall is a composite structural panel that integrates a galvanized or color-coated steel sheet with an Expanded Polystyrene (EPS) insulation core. It is widely used in industrial buildings, cold storage, prefabricated houses, cleanrooms, and warehouse enclosures, offering a balanced combination of thermal insulation, mechanical strength, and cost efficiency.

This guide explores the design principles, material composition, engineering performance, industry standards, and installation protocols for steel plate EPS wall systems. It also addresses regulatory compliance and answers common technical questions to support engineers, architects, contractors, and procurement specialists.

What is a Steel Plate EPS Metal Wall?

A Steel Plate EPS Metal Wall, also referred to as an EPS Sandwich Panel, consists of:

• External and internal steel sheets (usually PPGI/GI/GL, 0.3–0.6mm thick)

• EPS core insulation (ranging from 50mm to 200mm thick)

• A continuous lamination process that bonds the layers under pressure and heat

This panel type is designed for non-load bearing walls, partitioning systems, and thermal envelope structures where insulation, speed of installation, and material economy are essential.

Material Composition and Layer Configuration

Key Performance Characteristics

1. Thermal Conductivity

• EPS thermal conductivity: λ = 0.033–0.038 W/m·K

• Heat transfer coefficient (U-value) for 75mm panel: ~0.45 W/m²·K

• Complies with ASHRAE and EN ISO 6946 energy efficiency targets

2. Compressive Strength

• EPS core: ≥100 kPa at 10% deformation (EN 826)

• Suitable for wind pressure zones up to 1.5–2.5 kN/m² (depending on fasteners and framing)

3. Fire Resistance

• EPS is combustible (Euroclass E) unless modified with flame retardants

• Not suitable for buildings requiring non-combustible façade systems unless encapsulated

• Can meet GB 8624 B2/B1 or ASTM E84 Class C fire ratings

4. Acoustic Performance

• Limited sound insulation (~23–28 dB for 100mm EPS panel)

• Not ideal for acoustic-sensitive zones; use rock wool cores where required

5. Weight and Handling

• Light density (~10–13 kg/m² for 75mm panel), ideal for fast installation and low structural load

• Requires edge protection during transport and installation

Applications of Steel Plate EPS Metal Walls

Installation Guidelines and Technical Precautions

Panel Installation

• Installed using hidden fasteners (self-tapping screws with neoprene washers)

• Panels can be installed vertically or horizontally, depending on structural framing

• Tongue-and-groove interlock ensures wind and thermal sealing

Expansion Allowance

• Metal sheeting expands with temperature: provide ≥5 mm per 3 m panel length in high-temperature zones

• Avoid rigid fixing to allow for expansion/contraction

Fire Safety Precautions

• EPS must be protected with fire-rated linings in occupied or regulated zones

• Avoid electrical conduit embedded directly in the EPS core

Vapor and Moisture Management

• Seal all joints with butyl tape or polyurethane foam

• Maintain vapor barrier continuity on the warm side of insulation

Frequently Asked Questions (FAQs)

❓ Is EPS metal wall panel suitable for high-rise construction?

Not typically. EPS panels are non-load bearing and have limited fire resistance, making them more suitable for low-rise industrial or prefab applications.

❓ Can EPS metal walls be painted or customized?

Yes. The steel surface can be pre-coated in any RAL color, and custom printing is possible. Internal linings may also include anti-bacterial coatings.

❓ How does it compare to PU or rock wool panels?

Yes, but only for low-slope or small-span roofs with additional waterproofing layers. PU or rock wool panels are better suited for roofing applications.

❓ Is EPS recyclable?

Yes. EPS is recyclable, but not biodegradable. Many manufacturers offer recycling programs or repurposing of scrap material for packaging.
