Our operations are certified by ISO9001 International Quality Management System and ISO14001 Environmental Management System, ensuring that every product meets international standards.
With more than 200 employees and over 300 brand stores, Delanshini continues to deliver reliable aluminum window and door solutions trusted by customers worldwide.
Aluminum sliding windows are a modern and practical solution for both residential and commercial buildings. Designed with sleek frames and smooth operation, they provide excellent ventilation and natural light while saving space. With their elegant appearance, durability, and easy maintenance, aluminum sliding windows have become one of the most popular window styles for contemporary architecture.
Our Aluminum Fence Gate is designed for both residential and commercial applications, combining modern aesthetics with long-lasting durability. Manufactured from high-quality aluminum alloy, this gate offers excellent corrosion resistance, lightweight strength, and low maintenance requirements.
Cast aluminum doors are premium, durable doors designed for modern residential, commercial, and industrial spaces. Known for their strength, corrosion resistance, and aesthetic versatility, cast aluminum doors provide long-lasting performance while allowing for elegant and contemporary designs. At Delanshini, our cast aluminum doors combine precision engineering with superior materials to create doors that are as functional as they are beautiful.
French doors and windows are classic architectural elements known for their elegance, natural light, and timeless design. Featuring large glass panes and symmetrical frames, they create a bright and inviting atmosphere while adding charm and sophistication to any home. Whether used in modern houses, villas, or traditional buildings, French designs enhance both aesthetics and functionality.
Aluminum casement windows are a versatile and stylish choice for modern architecture. Hinged on the side and able to open outward or inward, they provide excellent ventilation, clear views, and a clean, timeless look suitable for both classic and contemporary spaces.
Folding doors, also known as bi-fold doors, are designed to create a seamless connection between indoor and outdoor spaces. Composed of multiple panels connected by hinges, these doors fold neatly to one or both sides, allowing for a wide and unobstructed opening.
Bottom rolling sliding doors are designed for smooth and stable operation, especially in large or heavy door systems where top-hung installation is not feasible. Instead of suspending the weight from the top frame, bottom rolling systems use a floor track with precision rollers that evenly distribute the door’s load. At Delanshini, we specialize in high-quality aluminum bottom rolling sliding doors that combine modern aesthetics, robust performance, and effortless functionality.
A sunroom is a bright, versatile living space designed to bring natural light into your home while offering protection from wind, rain, and outdoor temperatures. Built with expansive glass panels and durable framing, a sunroom creates a seamless indoor–outdoor experience—perfect for relaxing, entertaining, or simply enjoying panoramic views year-round. Whether attached to a house or built as a standalone structure, a sunroom enhances both the comfort and value of your property.
Hinged doors are one of the most traditional and widely used door styles, known for their simplicity, reliability, and timeless design. A hinged door is attached to the frame by one or more hinges, allowing it to swing open and close smoothly either inward or outward. At Delanshini, we offer high-quality aluminum hinged doors that combine classic functionality with modern aesthetics.
