In the modern architectural and automotive sectors, the demand for high-performance OEM/ODM Glass Setting Blocks has reached unprecedented levels. As buildings grow taller and automotive designs become more aerodynamic, the role of these small yet critical components is vital. Glass setting blocks, primarily made from EPDM, Silicone, or PVC, serve as the structural buffer between glass panels and their frames. They ensure proper weight distribution, allow for thermal expansion, and prevent the catastrophic failure of glass edges due to direct contact with rigid frames.
Currently, the global market is shifting towards high-durability materials that can withstand extreme UV exposure and temperature fluctuations. From the skyscrapers of Dubai to the electric vehicles (EVs) manufactured in Germany, precision-engineered glass shims and setting blocks are the unsung heroes of safety and longevity.
Transitioning from standard rubber to high-density EPDM for superior weather resistance and noise reduction in automotive and architectural glass.
Increasing demand for customized shapes (H, U, W, and P shapes) to fit innovative curtain wall designs and complex automotive windscreen profiles.
Global procurement teams are prioritizing suppliers with eco-friendly production processes and recyclable synthetic rubber materials.
Zhejiang Haala Automotive Parts Co., Ltd. is a leading medium-sized private enterprise dedicated to the research, development, and mass production of premium vehicle and architectural sealing strips. Located in the industrial heart of China, we specialize in high-precision OEM/ODM Glass Setting Blocks and specialized rubber extrusions.
Our facility is equipped with state-of-the-art EPDM production lines, automated molding machines, and rigorous testing laboratories. This integrated "one-stop" production model—spanning from raw material preparation to custom mold development—allows us to maintain competitive pricing without compromising on international quality standards.
We take pride in our "Quality First" philosophy, ensuring that every batch of glass pressure strips, silicone spacers, and EPDM gaskets meets the exact Shore A hardness and durability requirements of our global clients.
Businesses in North America, Europe, and the Middle East are increasingly looking for reliable glass setting block suppliers in China to mitigate rising costs. Key procurement factors include:
From commercial storefronts to residential window manufacturing, our glass blocks are utilized in:
As a specialized supplier, our range covers everything from standard EPDM shims to complex composite extrusions.

Professional production of various automotive sealing strips, door and window sealing strips, air conditioning sealing strips, furniture sealing strips, and electrical sealing strips.
The company has strong technical strength and management experience. Testing methods are complete, forming a one-stop production mode of raw material preparation, mold development, and product molding.
Our products are sold to Japan, Germany, the United States, France, Iran, Australia, Türkiye, India, Nigeria, Brazil, Russia and other countries with high praise.
Choosing the right glass setting block supplier involves understanding the material science behind the product. At Zhejiang Haala, we utilize advanced vulcanization techniques to ensure that our rubber products maintain their elasticity over decades of use. When glass is installed, it rests on these blocks; if the material is too soft, the glass may sink and touch the frame, leading to breakage. If it is too hard, it can cause pressure points.
Our engineering team works closely with OEM clients to determine the optimal Shore A hardness—typically ranging from 70 to 90 durometer—specifically designed to support the dead load of the glass while providing enough cushioning to absorb structural movements. This level of precision is why we are the preferred suppliers for international automotive glass mounting and architectural glass curtain walls.
Every market has unique requirements. In the European market, there is a high emphasis on chemical compatibility with structural glazing silicones. In Southeast Asia, the focus is on extreme heat resistance. Our ODM services allow us to modify material formulations to suit these local environmental conditions, providing a truly localized solution for our global partners.
For many years, Zhejiang Haala has adhered to the enterprise policy of "Reputation First," providing products and services to customers worldwide. We continuously strengthen the quality awareness of our employees and introduce high-tech equipment to achieve 100% customer satisfaction. Whether you are looking for a bulk Glass Setting Blocks Supplier or a partner for complex ODM rubber sealing projects, we have the technical strength and production capacity to deliver.
Our commitment to being "people-oriented and technology-driven" ensures that we remain at the forefront of the industry. We warmly welcome professionals and businesses from all over the world to cooperate with us and seek common development in the field of automotive and architectural sealing solutions.
