STEEL

Shumaker Industries is committed to manufacturing durable replacement drums by prioritizing high-quality steel. The key to our longevity lies in our approach to steel sourcing and formulation. Here's how we achieve it:

Forge Strong Partnerships with Domestic Suppliers:

We consistently procure steel from domestic mills. While competitors turn to cheaper foreign alternatives amid price fluctuations, we remain steadfast in our choice of domestic mills. This ensures the steel's consistency and reliability across every drum we produce, year after year.

Develop a Custom Steel Formula for Durability:

Through collaboration with domestic mills and leveraging our expertise in concrete mixers, we've developed a proprietary steel formula tailored to meet the demanding wear requirements of the concrete industry. This exclusive formula is unique to Shumaker Industries, granting us unmatched quality control and performance.

Achieve Optimal Performance Characteristics:

Our steel formula achieves a Brinell hardness rating of 200, ensuring superior resistance to wear. Importantly, we focus not only on surface hardness but also on achieving consistent hardness throughout the plate thickness. This durability allows our drum shells and blades to withstand extensive use in concrete mixing applications.

Ensure Consistent Thickness and Quality:

By using domestic steel, measured in the English system, we maintain precise thickness standards critical to our drum's performance. In contrast, foreign market metals often vary in thickness due to their reliance on the metric system. Our commitment to consistent quality translates into significant long-term savings and reliability for our customers.

In summary, Shumaker Industries' commitment to high-quality, domestically sourced steel and our proprietary formulation ensures that our replacement concrete mixer drums are built to last, meeting the rigorous demands of the ready-mix concrete industry.
