Welcome to Hemaokang Steel (Shandong) Co., Ltd., a dedicated manufacturer of steel building products. We take pride in offering high-performance metal wall panels designed for durability and architectural elegance. Our Metal Wall Panel comes with a 5-year surface warranty and a mill test report for every shipment, ensuring complete material traceability and transparent quality control. Whether you are a contractor, builder, distributor, or architect, this product provides a dependable external cladding solution that keeps maintenance low and visual appeal high.
The core of our metal wall panel is a high-strength steel substrate, available in galvanized, Galvalume, or aluminum-zinc coated finishes. This variety allows customers to select the ideal base material according to their project environment and budget. The panels are then treated with a protective and decorative coating system that resists corrosion, UV rays, moisture, and mechanical damage. As a result, buildings maintain their clean appearance throughout the warranty period and beyond.
We know that every construction project is unique. That is why our wall panels can be manufactured in multiple thicknesses, widths, lengths, and profile shapes. Custom RAL colors are also supported to match the façade design requirements. From simple flat panels to corrugated or ribbed patterns, our production process can accommodate both standard and engineered profiles.
Key Features
- High-strength steel core: Made from cold-rolled steel with metallic coating, delivering excellent load-bearing capacity and stability.
- 5-year surface warranty: Protects against coating peeling, cracking, chalking, and fading under normal atmospheric exposure.
- Mill test report: A comprehensive document for each production batch records the material’s chemical and mechanical properties, guaranteeing traceability from cradle to site.
- Advanced coating options: Choose PVDF, SMP, HDPE, or premium polyester finishes for outstanding weather resistance.
- Low maintenance: The smooth, anti-adhesive surface prevents dirt adhesion, reducing cleaning frequency and costs.
- Easy cutting and fastening: Panels can be readily cut, drilled, and fixed with common tools, speeding up installation on site.
- Environmentally friendly: Steel panels are recyclable and produced under controlled energy and waste management practices.
- Versatile aesthetics: Various profiles, textures, and colors give architects creative freedom without sacrificing performance.

Enhanced Weather Resistance: The zinc or aluminum-zinc coating provides sacrificial protection to edges and scratches, while the topcoat blocks moisture and UV radiation. This dual-layer defense prevents rust creep and color change, even in coastal or high-humidity environments. Buildings outfitted with our panels enjoy lower life-cycle costs and extended cladding service life.
Material Traceability and Quality Confidence: In many overseas projects, owners and consultants demand factory evidence to verify compliance with contract specifications. Our mill test report contains the exact chemical analysis and mechanical values of the steel used. This document allows engineers to confirm the yield strength, elongation, coating thickness, and surface quality of the delivered goods. You can keep the report as a permanent record for future maintenance or inspection needs.
Fast and Economical Installation: Because our wall panels are proportioned to reduce unnecessary weight, labor can move and mount them quickly. The panels connect securely to steel or timber framing using self-tapping screws or concealed clip systems. This reduces construction time and lowers the total installed cost compared with heavier masonry or precast systems.
Application Scenarios: The panels are ideally suited for factory buildings, warehouses, distribution centers, commercial offices, showrooms, farm buildings, and residential perimeter walls. They can be used as exterior wall cladding, interior partition liners, ceiling soffits, and canopy fascia. The tight seam design also helps maintain building hygiene and pest control.

Dedicated Quality Assurance: Every production order goes through a strict inspection process, including visual surface checks, thickness measurements, and package integrity verification. Our qc team samples each batch and retains records for at least three years. If any issue arises from material properties, we can trace back to the original steel coil using the mill test report number.

Frequently Asked Questions
1. What does the 5-year surface warranty actually cover? The warranty covers unsightly surface defects like peeling, chalking, flaking, and excessive fading under standard atmospheric conditions, as long as the panels are installed and maintained properly. The warranty terms are outlined in the supplied certificate.
2. Why is a mill test report important for material traceability? The mill test report records the exact chemical ingredients and mechanical properties of the steel coil. It acts as a passport for the material, allowing buyers to verify that the wall panel matches the documented specification. This is especially valuable for projects requiring strict material traceability.
3. Can I order custom dimensions and colors? Absolutely. We offer thicknesses from 0.3 mm to 1.5 mm, effective widths from 800 mm to 1200 mm, and lengths based on your requirements. Color matching is available for RAL codes or custom samples.
4. Are the panels suitable for coastal or industrial environments? Yes. For corrosive atmospheres, we recommend Galvalume or aluminum-zinc coated substrates with PVDF coating. This combination provides outstanding chloride resistance and salt-spray performance. Our engineers can help you choose the right material grade.
5. How are the panels packaged for overseas delivery? Panels are stacked flat, wrapped with waterproof paper or film, and secured on strong steel pallets or wooden crates. Edge protectors and rust-preventive packaging are used to ensure they arrive without scratches or deformation.
6. What is your minimum order quantity? The MOQ varies by profile and thickness, generally 300 to 500 square meters. For samples and trial orders, we can reach a flexible arrangement. Please contact us with your requirements.
7. Do you provide technical installation guidance? Yes, we can offer installation instructions, flashing details, fixing recommendations, and CAD drawings. Our team also answers technical questions during the quotation stage and after delivery.
8. How long will it take to produce an order? Production normally requires 10 to 25 working days after receipt of deposit and final drawings. Larger orders or special custom-coated colors may take a little longer, but we always provide a clear delivery deadline in the confirming order.
