Hemaokang Steel (Shandong) Co., Ltd. is proud to present our 0.35mm Thick Galvanized Steel PU Metal Wall Panel – a premium solution for exterior building envelopes that demand both waterproofing and thermal insulation. Manufactured with high-quality galvanized steel and rigid polyurethane foam core, this panel offers exceptional durability, energy efficiency, and ease of installation. As a trusted supplier with annual export value exceeding US$50 million and ISO9001 certification, we ensure every panel meets rigorous international standards.
Our PU metal wall panel is engineered to protect structures from harsh weather while significantly reducing heating and cooling costs. The 0.35mm thick galvanized steel outer sheet provides superior corrosion resistance and mechanical strength, while the PU foam core guarantees excellent thermal performance. Whether for commercial warehouses, industrial plants, cold storage rooms, or residential extensions, this panel delivers long-lasting performance.
Key Features & Technical Specifications
- Outstanding Thermal Insulation: PU foam core with low thermal conductivity (λ ≤ 0.024 W/m·K) minimizes heat transfer, saving up to 40% energy on climate control.
- 100% Waterproof Design: Tongue-and-groove joint system ensures seamless assembly, preventing water infiltration even under heavy rain or snow.
- 0.35mm Galvanized Steel Skin: Hot-dip galvanized Z275 coating provides excellent anti-corrosion performance, suitable for coastal and industrial environments.
- Lightweight yet Strong: Panel weight approx. 10–15 kg/m² (depending on thickness), reducing structural load while maintaining high load-bearing capacity.
- Fire Resistance: Options available with Class B (EN 13501) and Class A2 fire-rated PU foam (upon request). Please contact us for specific certifications.
- Easy & Fast Installation: Pre-drilled holes and hidden fastener profile speed up assembly, lowering labor costs.
- Eco-Friendly: PU foam is CFC/HCFC-free and recyclable; galvanized steel is 100% recyclable.

Frequently Asked Questions (FAQ)
-
Q: Can this panel be used for both exterior walls and roofs?
A: Yes, our 0.35mm Galvanized Steel PU Panel is suitable for both vertical wall cladding and roof applications. For roofs, we recommend selecting an appropriate panel thickness (at least 75mm) and adding a standing seam profile if needed. -
Q: What is the maximum length you can produce?
A: We can produce panels up to 12 meters in length to minimize horizontal joints. However, typical lengths are 2–10 meters for easier handling. Please consult our sales team for specific requirements. -
Q: How do you ensure the waterproof performance?
A: The panel features a patented tongue-and-groove joint with a built-in EPDM gasket (optional, upon request) and a self-locking mechanism. The galvanized steel surface has a high-quality PU coating that repels water. We also offer sealing tape and flashings for additional protection. -
Q: Is the PU foam environmentally friendly?
A: Yes, our PU foam is CFC/HCFC-free and has zero ozone depletion potential. The manufacturing process complies with RoHS standards. The panels contribute to green building certifications like LEED due to their energy-saving properties. -
Q: What fire rating options are available?
A: Standard panels achieve Class B (EN 13501) fire performance. For projects requiring higher fire resistance, we can supply Class A2 or Class A1 panels using special mineral-core or fire-retardant PU formulations. Please contact us for detailed test reports. -
Q: Can I get a color match for my existing building?
A: Absolutely. We offer a wide range of colors including RAL and custom shades. The topcoat is a durable polyester or PVDF paint system that resists UV fading. Minimum order quantity for custom colors may apply. -
Q: What is the delivery time for a container of panels?
A: For standard sizes (1000mm width, 50mm thickness), production usually takes 15–20 working days after deposit. Custom orders may require 25–30 days. We work closely with shipping agents to arrange timely delivery. -
Q: Do you provide samples before bulk order?
A: Yes, we provide free samples (A4 size) for quality evaluation. You only need to cover the express shipping cost. Sample preparation takes 3–5 days.
