Custom Grain Bin Floor Screen Replacement for Smaller‑Diameter Grain
Project Summary
Crawford Biotech fabricated a custom grain bin floor screen for a customer who needed to adapt an existing grain tank for smaller‑diameter grain. The original screens were designed for larger material and were no longer suitable for the customer’s application.
Rather than replacing the tank, Crawford Biotech produced a custom false bottom grain bin floor based on the dimensions of the existing screens, with revised opening sizes.
Scope of Work
The project involved:
- Measuring the customer’s existing grain tank screens
- Matching panel size, shape, and mounting configuration
- Fabricating new screens with modified opening dimensions to accommodate smaller grain
The finished components were designed to install in the same location as the original screens, allowing the grain tank to be reused without structural changes.
Custom Fabrication Considerations
This project reflects common requirements associated with custom grain bin floor fabrication:
- Opening size must correspond to material diameter to reduce material loss
- Replacement panels must align precisely with existing tolerances
- Custom fabrication allows targeted changes without redesigning the full system
Because the application requirements were specific, standard off‑the‑shelf grain bin floor panels were not appropriate.
Applications
Custom grain bin floors and false bottom screens are often required when:
- Grain size or material specifications change
- Existing equipment is repurposed for a new process
- Replacement components are no longer commercially available
Crawford Biotech supports these use cases through application‑specific metal fabrication.
Custom Grain Bin Floor Fabrication
Crawford Biotech designs and fabricates custom grain bin floors, false bottoms, and grain tank screens to meet exact dimensional and application requirements.
For operations needing replacement grain bin floor components or custom‑sized screen panels, Crawford Biotech provides fabrication solutions that integrate with existing equipment.
