Technical Info - Porcelain Enamel Panels

At TECO, we take porcelain enamel panels—also known as vitreous enamel panels (VE panels)—to the next level with our advanced, high-temperature fusing process. As a leading enamel wall panel supplier, we ensure that our procelain steel panels are not only durable but also highly resistant to damage and built to last for decades.
How Do We Make TECO’s Porcelain Enamel Panels?
It all starts with carefully preparing the steel sheets. First, we thoroughly clean and treat the raw steel, removing any impurities to create a strong foundation. This step is crucial because it ensures a perfect bond between the steel panel and the enamel coating.
Next, we apply a base coat of enamel and fire it at over 830°C. This extreme heat permanently bonds the enamel to the steel panel, creating a tough, durable surface. But we don’t stop there! To achieve vibrant colors, maximum durability, and a smooth finish, we add an extra layer of porcelain enamel. This layer is then fired again, locking in color retention, scratch resistance, and weather protection.
Why Are TECO’s Porcelain Enamel Panels a Smart Choice?
Thanks to this precise manufacturing process, our porcelain enamel steel wall panels (VE panels) offer a long list of features and advantages, making them the perfect choice for various applications, including architectural facades, tunnels, and railway station metal wall claddings.
