Do you know the material of the sliding gate pulley wheel?

In the contemporary field of architecture and facility management, heavy duty sliding gate wheel  play an indispensable role. They are not only widely used in enterprises, institutions, and private residences, but have also become the standard configuration for public building entrances. However, there are numerous types of sliding gate wheel on the market, with significant price differences. What exactly are the reasons behind this?

The material of the wheel components is one of them. This article will delve into a guide for choosing the material of sliding door pulleys to help you make an informed decision.
The Importance of Sliding Door Pulley Materials

Let's take the commonly used sliding gate wheel with exterior support as an example today(our item code : LSV). The LSV series sliding gate wheel mainly consist of four key components: the bracket, the wheel, the bearing, and the rivet. Choosing the best materials for these components is crucial for ensuring the cost-effectiveness of the wheel. 
Selection of Bracket Material The bracket, as the base of the pulley wheel, directly affects the stability and durability of the pulley. The bracket is made from iron plates processed by a punch press, and the common iron plate materials on the market include: hot-rolled plates, pickled plates, and cold-rolled plates. Cold-rolled plates, with their excellent strength and surface finish, are the preferred choice in the high-end market.

For instance, Our Company uses cold-rolled plates to manufacture brackets, ensuring the strength and appearance quality of the sliding gate rollers. Careful Selection of Roller Material The roller, as the core component of the pulley system, directly relates to the pulley's load-bearing capacity and wear resistance. Round steel is the raw material for making rollers, and round steel materials are classified into low-carbon steel, medium-carbon steel, and high-carbon steel based on carbon content. Medium-carbon steel, such as China's 45# steel, is particularly suitable for making rollers that bear heavy loads and are frequently used in sliding doors due to its high strength and hardness. Although the cost is higher, the durability of medium-carbon steel rollers makes them an extremely cost-effective choice. 

All pulleys of Open Company are made of medium-carbon steel, which not only enhances the wear resistance of the pulleys but also improves the smoothness of the wheels, making them more durable and aesthetically pleasing. Conclusion and Experience Sharing With 25 years of production experience, we recommend considering the materials of both the bracket and the roller when choosing sliding door pulleys. Although the combination of cold-rolled plate brackets and medium-carbon steel rollers has a slightly higher initial investment, the long-term benefits are significant, providing stable and reliable performance for sliding gates. Preview of Next Content In the upcoming content, we will further explore the role of bearings and rivets in sliding gate wheels, as well as the impact of different materials on the overall price and quality of the pulleys. Stay tuned for more professional insights and practical suggestions. We also look forward to exchanging experiences with industry colleagues to jointly improve product quality.
