    A Superior Powder-Coated Finish

    The Midnight Slate high-quality powder-coated finish is applied by a UK specialist trusted by Jaguar Land Rover and Aston Martin. Specially formulated for Rhino Greenhouses, the coating process is chromate-free and environmentally friendly. Aluminum is notoriously difficult to paint, so each part undergoes a 12-stage pre-treatment before the powder is electrostatically applied for a flawless, even finish. Baked at 200°C, this process ensures exceptional durability, allowing us to offer an industry-leading 25-year guarantee—a level of quality even luxury cars don’t match!
