Profile: Metal Window Corp. is a manufacturer of aluminum windows and doors. Our custom sliding doors come in 6 basic configurations and also custom configurations. Our products are fabricated from extruded aluminum. Our product line includes aluminum casement windows, screens and hardwares. We offer anodized and organic costing services. Our electrolytic anodizing process provides substantial improvements over the natural oxide film because of the greater thickness, density and hardness of the factory-produced finishes.
