DQ Type Steel Elevator Bucket Overview

DQ type steel elevator bucket is a shallow bottom bucket designed for high-speed centrifugal discharge applications. It is manufactured using a one-piece stamping process, forming a seamless and high-strength structure.

Seamless one-piece design ensures higher strength compared with welded buckets.

Manufacturing Process

Both carbon steel and stainless steel buckets are produced through a deep drawing stamping process, where each bucket is formed as a single unit without welding.

This seamless structure improves overall strength, durability, and wear resistance.

Due to the material characteristics of steel, the bucket depth is slightly lower than that of plastic buckets. As a result, the “C” dimension remains close between models such as DS1314 and DQ1314, making them suitable for similar applications.

We offer all standard sizes in both carbon steel and stainless steel. For stainless steel buckets requiring a larger “C” dimension, thicker plate material can be used to ensure the required forming depth despite its lower elongation.

Design Classification

There are two main types of stamped steel buckets:

  • DQ type – shallow bottom bucket for centrifugal discharge
  • DS type – deep bottom bucket for gravity discharge

This product refers to the DQ type.

Use advice

  • Use for the high-speed centrifugal material discharging.
  • Recommend “Z-Y”+5% as the usable capacity for engineer design.

Why Are Stainless Steel Elevator Buckets More Expensive?

Stainless steel elevator buckets are generally more expensive due to both material and manufacturing factors:

1. Higher Raw Material Cost
Stainless steel is significantly more expensive than carbon steel, which directly impacts the base cost of the bucket.

2. More Challenging Manufacturing Process
Compared to carbon steel, stainless steel has lower elongation, making it more difficult to form during the stamping process. This increases the risk of defects such as cracking or surface imperfections.

However, they offer superior corrosion resistance and longer service life in demanding environments.

As a result, the production process typically has a higher rejection (scrap) rate, which contributes to the overall cost.

In Summary
The price of stainless steel buckets is not determined by material cost alone, but also by the increased manufacturing complexity.
However, we are able to produce all standard sizes listed, ensuring reliable supply for your application needs.
