Enhancing Chicago's Skyline: The Art and Craftsmanship of Glass Door and Curtain Wall Manufacturers

The Design Process

Every journey begins with a single step, and the creation of a lever latch door handle is no exception. Our design process starts with the needs of our customers, who require door handles that are not only functional and durable but also aesthetically pleasing.

Our team of talented designers initiates the process by sketching and prototyping various concepts inspired by both classic and contemporary styles. After countless iterations, the final design is chosen based on its visual appeal, ergonomics, and ease of installation.

Material Selection

The next phase is determining the appropriate materials for the door handle. We prioritize using high-quality materials that meet and surpass industry standards. Our range of materials includes:

Solid Brass: Known for its durability and resistance to corrosion, solid brass is an excellent choice for door handles. As a bonus, it also offers a luxe feel and appearance.

Zinc Alloy: A popular and cost-effective option, zinc alloy provides excellent strength and allows for intricate designs due to its precise casting properties.

Stainless Steel: Ideal for its low maintenance and sleek appearance, stainless steel is both formidable and corrosion-resistant.

Production Techniques

Once the design and materials have been finalized, production begins. We employ state-of-the-art machines and technologies to ensure accuracy and consistency, while also preserving the craftsmanship that sets our door handles apart.

Forging: This process uses either hot or cold forging to shape the metal, resulting in a stronger and more solid structure.

Casting: In this method, molten metal is poured into a mold and then allowed to cool and solidify, creating detailed and intricate designs.

CNC Machining: An automated process that uses computer-controlled tools to cut, shape, and refine materials ensures precision, accuracy, and a smooth finish.

Finishing Touches

Post-production, the door handles are polished and treated with various finishes to enhance their appearance and durability. Popular finish options include:

Satin Chrome: A brushed silver finish offering a minimalistic, modern touch.

Oil-Rubbed Bronze: A traditional and rich finish lending character to the door handle.

Polished Brass: A glossy, golden finish providing an elegant and timeless look.

Matte Black: An increasingly trendy choice, matte black offers a bold and sophisticated aesthetic.

Rigorous Quality Testing

Before we send our finished door handles into the world, they must pass several rigorous tests to meet and exceed industry standards. These tests include:

Corrosion Testing: By exposing the door handles to extreme weather conditions, we can ensure they will withstand potential damage and maintain their appearance.

Durability Testing: Through repetitive use and weight testing, we can guarantee long-lasting functionality.

Security Testing: Our door handles are examined under forced entry scenarios to ensure they provide adequate resistance against potential intruders.

Innovative Solutions

We continually strive to stay ahead of the curve by incorporating new technologies and design trends. This includes researching advancements in materials, exploring stylish and cutting-edge designs, and adopting environmentally friendly practices in our manufacturing process. By embracing these innovations, we can continue to offer unparalleled quality, style, and functionality in our lever latch door handles.
