Shenyang Qiangyun Color Steel & Steel Structure Co., Ltd. is one of the most reliable manufacturers and suppliers of 50mm eps sandwich panel eps roof in China. With abundant experience, we are committed to providing high quality customized products with competitive price. Welcome to wholesale advanced 50mm eps sandwich panel eps roof in stock here from our factory. Also, pricelist is available.

Product Overview

Our 50mm EPS sandwich panel is purpose-built for the harsh Middle East climate. Compared with thicker 75mm/100mm panels, it provides sufficient thermal insulation for light-steel factories and small warehouses at lower material and logistics cost, cutting total project budgets by 20–35% while complying with local building codes. Equipped with anti-UV, solar-reflective coating and reinforced edge sealing, it withstands strong sunlight, high heat, sandstorms and coastal salt spray.

Key Features & Benefits

Superior Thermal Insulation for Extreme Heat

EPS core with thermal conductivity <= 0.046 W/(m.K) effectively blocks heat transfer through the roof.
Light-colored reflective coating option (white/light gray) reflects up to 85% of solar radiation, significantly reducing roof surface temperature.
Can reduce indoor temperatures by 8-12C compared to uninsulated single-layer roofing, lowering air conditioning costs by up to 30%.
50mm thickness provides optimal R-value (R-3.5) for Middle Eastern climate zones - no need for excessive thickness

Middle East Climate-Resistant

Anti-UV topcoat resists color fading and chalking under intense solar UV exposure (QUV tested >= 1000 hours).
Salt-spray resistant coating passes 500-hour neutral salt spray test (ASTM B117) - ideal for coastal Gulf projects.
Reinforced edge sealing prevents sand and moisture ingress at panel joints.
Withstands temperature swings from -5C to 70C without warping, cracking, or delamination.

Fire Safety

Flame-retardant EPS core achieves B2/B1 fire rating (EN 13501-1, ASTM E84).
Meets Middle East local building code requirements for commercial and industrial structures.
Optional upgraded B1-grade flame-retardant EPS available for stricter fire safety zones.

Lightweight & Structural Efficiency

Self-weight of only 8-10 kg/m2 significantly reduces load on light-steel structure frames.
Ideal for large-span warehouses, factories, agricultural greenhouses, and temporary buildings.
Wind pressure and structural stability tested per international standards.

Precision Engineering & Easy Installation

Tight side-joint interlocking sealing prevents water infiltration during desert rainstorms.
Length customizable from 1m to 20m, reducing on-site cutting waste by 20%+.
Pre-punched fastener holes for quick installation - one worker can install up to 40 sqm/day.

Industry Pain Points & Our Solutions

The Middle East market faces unique challenges when selecting EPS sandwich panels for light-steel construction projects. Below are the most common pain points we see in the field - and how our product addresses each one:

Common Pain Point	Our Solution
Pain Point 1: Blindly selecting 75mm/100mm panels for projects that only need 50mm, resulting in 20-35% higher material costs, heavier structural loads, and increased shipping costs.	Our 50mm standard thickness is scientifically calculated for Middle Eastern thermal requirements - delivering optimal R-value (R-3.5) without unnecessary cost or weight. Can reduce total project cost by 20-35% compared to over-specified alternatives.
Pain Point 2: Low-quality 50mm panels with loose EPS foam, poor coating durability, and rough edge sealing - failing local inspection and requiring frequent repairs.	Our high-density compaction process (20 kg/m3) ensures uniform foam structure. Anti-UV topcoat passes 1000-hour QUV testing. Reinforced edge sealing prevents sand/moisture ingress. Every batch tested before shipment.
Pain Point 3: Coastal projects suffering from salt-spray corrosion, causing rapid rusting and coating peeling within 2-3 years.	Our salt-spray resistant coating passes 500-hour neutral salt spray test (ASTM B117). PPGL (polyester-polyurethane coated steel) option available for maximum coastal protection.
Pain Point 4: Roof surface temperatures exceeding 70C in summer, making interiors unbearable and increasing AC loads by 40%+.	Optional high-solar-reflectance white/light-gray coating reflects 85%+ of solar radiation, reducing roof surface temperature by up to 15C and indoor temperatures by 8-12C.
Pain Point 5: Fragmented supplier coordination - separate vendors for panels, accessories, and documentation causing delays and quality gaps.	One-stop solution: panels + accessories + export documentation + technical support. We handle everything from custom order to factory gate delivery, streamlining your procurement process.
