- Slip Resistance: The serrated surface (optional) and open grid design offer superior traction even when wet or oily, reducing the risk of slips and falls.
- Efficient Drainage: Open area up to 70% allows rapid water and liquid flow, preventing ponding and reducing the risk of chemical spills accumulating.
- Easy Installation & Maintenance: Lightweight yet strong, these gratings can be quickly cut and fitted on site. They require minimal maintenance – just occasional cleaning.
- Customizable Dimensions: Width, length, bar thickness, and spacing can be tailored to your specific trench dimensions and load requirements. Contact us for custom quotes.

Frequently Asked Questions (FAQ)
