Trench Drain Grates Manufacturer for Industrial & Drainage Systems

Our trench drain grates are designed for efficient water drainage and heavy load applications. Ideal for industrial floors, roadways, and municipal drainage systems, they provide strength, durability, and anti-slip safety.

High Load Capacity: Suitable for pedestrian and vehicle traffic
Anti-Slip Surface: Serrated or safety grating options
Custom Fabrication: Designed to fit your drainage system

What Are Trench Drain Grates?

Trench drain grates are removable covers installed over drainage channels to allow water flow while supporting loads. They are typically made from steel bar grating or other anti-slip materials for durability and safety.

Depending on the application, serrated steel grating or anti-slip safety grating can be used to improve traction in wet or hazardous environments.

Q: What is the smallest hole you can produce?
A: Typical micro perforation starts at 0.3 mm; for smaller holes we recommend chemical etching — contact us with your exact spec.

Q: Do you offer custom patterns and prototypes?
A: Yes. We do prototypes with no MOQ. Send drawings or sample references to info@perfsheet.com.

Q: Can you cut panels to irregular shapes?
A: Yes. Provide a CAD file or drawing; laser or waterjet processes are suitable for complex outlines while preserving micro hole integrity.

Q: How do you handle edge finishing?
A: We can supply straight-cut edges, folded profiles, or hemmed edges. Hemming improves safety and aesthetics for visible edges.

Q: Can you produce curved panels?
A: Some materials can be roll-formed or pressed into curved shapes. Send radius and panel size; we’ll advise on manufacturability.

Q: Can you provide material certificates?
A: Yes — material certificates are included with shipments and we support third-party testing.

Micro perforated metal sheet manufacturing video

After perforation, especially for plates with very dense hole patterns, the perforated metal sheets will experience significant deformation. We perform flattening treatment after completing all perforation processes. Below is the video of flattening perforated metal sheets:

After the leveling process, our perforated metal sheets can be precisely laser-cut into any custom shape as required. Below is a production video demonstrating the laser-cutting process:
